Open Belgium 2021: Sharing open road data in Flanders The TN ITS way:

good morning everyone and welcome to this online version of open belgium i want to quickly thank our three main sponsors monodesign microsoft and against help vinyl on but without further ado i want to give the floor to steven one moment please getting started does that work for you yes okay so uh good morning everyone my name is stephan chubble i'm resp representing i'm the work group leader the technical specifications of the tn its platform and tn ids stands for transport network intelligent transportation systems so today i will be talking about um sharing open road data in flanders and europe the tni ts way i will give an introduction first and then lina here will continue focusing on the flemish context and giving you examples of what tnits is about and what it means um so without further ado here's the overview of my 10 minutes introduction so context introduction to tnits quick word on the tnits go project and i will also show you an overview of the european open road data exchange services and stop with a an outlook so first of all on the context so of course everyone is concerned about road safety and vehicle manufacturers over the last year have developed a number of technologies to support drivers keeping lane keeping safe speed you know even making sure that the car um drives correctly and shifts clear things like that so these are called advanced driver assistance systems and they typically work with a map in onboard of the vehicle that can that map can actually be for the driver for a visualization aid but it could also be for the car just to as i mentioned before um you know pick the right gear in an automatic gearbox so that map is is quite important uh if it's on board then of course it needs to be maintained because as it is a representation of the environment it needs to be correct and that's a crucial thing the maintenance of the digital map so the leading map makers have invested in a number of technologies to collect information on the road environment and bring that to their maps to update their maps think about this type of street view vehicles think about floating car data so monitoring either your mobile phone or your navigation device in your car and use these anonymous traces to update their maps but one important aspect of sources for changes for maps comes from government sources that's authoritative data a lot of that data already in europe is being published or made available as open data what is important is because the leading map makers they have high quality data map databases already the focus is on the changes of the road data so not necessarily the bulk as is data but the changes of the road data and there's also a common data model and interface required to do that because if you imagine like a leading map maker if they get access to authoritative data in one country they would prefer that it is that the same access would apply for authorities in different in different countries so common data model and interface and that's exactly where tnits jumps in so tnits is on one side it's an association it's a platform under the ertico umbrella but it's also technical specification so it's under the same technical specification technical committee what is it 278 working group 7 that's the its group and it's also a building block for today's and future mobility data space so on the right hand side of the slide you see a number of building blocks and each represents a domain where standardization of interfaces of data models has happened in the in the past or in the recent past so on the bottom you see vehicle sensor data there is a a standardization activity ongoing uh called sensoris to deal with that for traffic information you might have heard of dart x for multimodal there's also a group that's working on a technical specification so there's i would say complementarity in the [Music] technical specification for the exchange of mobility data and on the top right you see tnits as one of the building blocks for base layer data or base map data so tmits is a trusted and market driven mobility data exchange service trusted because authorities provide the data and market driven is because leading map makers are actually you know heavily involved in the both the association and the technical discussions and also the strategy of the platform so it's once the um i would say road authorities adopt the or implement such a service then they will be sure that at the end the map makers will consume the data and update their maps accordingly so what's in focus as i mentioned before tnits represents the data model the format the infrastructure to exchange primarily changes of road attributes for the maintenance of digital maps for different its services so we're talking about typically static road attributes attributes just speed limits traffic restrictions warning information ev alternative fuel charging point lane and information and so on so when we look at a typical tnits you see tnits infrastructure in place it's at the side of the road authorities when they publish changes of road data they do it in the tia and its compliant way and that's the the bridge so to speak to the map makers tnits does not address how the map makers provide fresh maps to the users be it the car a roadside unit a traffic center a portable navigation device or an in in vehicle system that's outside the scope of the tnits what is also interesting is in the red circle you see that the arrow goes both ways and that's the so-called so you see that the the changes streaming from left to right so towards the road towards the map makers but there's also feedback link that's uh specified and that actually reflects information that is provided by the map makers back to the road authorities which describes how the map makers actually decoded and integrated that data so let me go to the next slide so a word on the tnits association so i mentioned it's coordinated by ethico and currently the members are either road authorities mob service providers ideas and transport organization and you see some names so we have a lot or a strong nordic presence in the road administrations we we have the main map makers in europe on board tomtom here and geo junction so the association is supporting the european policy on rtti and its um it supports the standardization so this technical specification is available it offers implementation support so if a road authority wants to implement such a tnits service it can get support from the association and that support might be the access to the reference model so the uml that describes the data content and the exchange infrastructure then it's also about building the brand and the trust so at the end at the driver's side at the end of the data users it needs to be known that the data the maps are maintained vit and igs process as that increases the reliability of that information and therefore also the service um we have worked for over uh seven years in strong cooperation with the european commission with sen with the joint research center and also with its associations and we are not doing that alone we are doing that together with a number of partner standardization groups i will not go in detail about them but just understand that there is a strong link of course with dynamic information and where whereas we focus on static road data there's a also the community that's working on traffic based on dynamic information traffic data that's the date x2 and the traffic management 2.0 uh platforms that work on that there's the link to automated driving via cam via the autodrive forum there's the link with the national access point program and then there's of course linked to send as a standardization body in europe uh one word on the or a few words on the tnitius go project so it's a ceph project it will actually end this year there are 20 partners in europe and the aim is to build at least 15 tnits services across europe which publish changes of road attributes typically minimum on the 10t network so there are a number of partners there that provides also updates for lower road classes i work on that do that immediately but and and that project is also supporting all standardization and implementation initiatives i mentioned the feedback loop here is where it's being prototyped and also new features for our new attributes for new cases are being explored in this project i will not go into a great detail on this slide however i would like to emphasize so this is the um the overview of the tnits services today in europe on the top row you have the country for which the service or who has implemented the service you say who is the pro data provider you see the status there is the coverage of the updates whether it's like for a full country and applicable for the 10t or all roads whatever on the so somewhere in the middle you see the map attributes which attributes and features are supported and typically as you can see speed limits are of top priority overrode information like street names root numbers that type of information road classes lane information is also [Music] made available by a number of [Music] road authorities it indicates the location referencing method either openlr or gml coordinate string it indicates the updates so the frequency of the update so you see that some countries are providing daily up uploads or daily changes of road attributes on their network there's the link to the service there is a mention if the service is also available via the national access point program and on the right hand side a little bit bigger is the state of the data license under which the data is provided so um the second row you see flanders that's the one you will be hearing more about on the next presentation so what's the link with open data first of all because of the origin of tnits and and the fact that that is um was supported by the european commission by a number of research projects the results of funded projects are typically open uh as much as possible so that's that's one thing on the other hand from the overview seen before that you can see that many or all almost all of the data providers offer data under open data license creative common force mentioned the most attribution is probably around 50 that means that you have to declare that you are using or you have to indicate the source of the information i've seen no share of light conditions which is very important to maximize the reuse of that information there is the technical specification with send which is available for marginal costs and of course you are free to use the specification to implement so on the implementation itself the web service to expose the data there is no there are no costs involved and there are some authorities who do not use an open data license yet but use the tnits specification and the interface for their pilot service asian in france so the national geographic institute in france is an example of that of such an authority now that brings me to almost my last slide so i'm not going to go too much in detail but this is the roadmap for tnits so we're now in 2021 we will finalize the tni ts go project and implement the feedback loop we will um have activities to include tnits work under the new national access point program in 2020 tnits will of course support the intelligent speed assistance which is mandated by the european commission in their general safety what is its grtsr program for new cars so by 2020 all new cars on the european market will need to have a speed assistance technology so tnits is going to support with fresh speed limit information so 2023 we will also see the involvement of cities and commercial road operators so currently the focus is on national road authorities but that will shift in the future because there might be important bigger cities metropolitan cities that have important data to share in the tnits way without going through a national body so 2025 extended road attributes and also work on automated licensing and 27 with support for the higher level of sae automation so for self-driving cars and on the further horizon we expect that there will be some harmonized worldwide system in place where there's a single process for sharing and reusing road data one half has to keep in mind that the map makers who consume the tnits data they are typically global players like tom thomann here and that's in fact the best way how they can consume the data the best way how they can [Music] forward the data to the end users and that's so the end user is typically the citizen and you know if you benefit the citizen that's of course in the interest of the um of the authorities so along the path you will see the maintenance of the technical specification and of course the growth of the community so if you just tuned in and um [Music] you know do not really understand what i was talking about so here it is in a nutshell the platform sot and it's a platform technical specification to exchange changes of raw data in europe the focus is on static road data and it's a key component in the mobility data space in europe and outside europe the road authorities provide trusted data to modern service providers and help thus to improve road safety and ensure efficient road use and currently there are a number of operational services in europe and the share most of them share their data under open data license more information you can find on the links you can have a look at them after the call or later on on the watching the movie uh latest news we recently had a webinar on tnips success stories which you might want to have a look at so that's it from my site i conclude my presentation and i give over the floor to lean i hear it uh thank you stefan for this uh interesting uh presentation um so in this uh second part we are going to focus more on the case of flanders so we want to make it a bit more concrete and at the end of the session you can ask questions if there are questions and we will answer them one by one you can also write them in the in the chat so you don't forget them before i start my presentation i want to do a a small poll to see whether there are already some people in the audience who know uh about our project um so you can answer just a yes or no um so we can have an overview of that okay so i i see that the most people answered it um i will publish the results in just a second so i see that uh about uh a third of the people already know about uh the project so i'm going to give these people a quick uh recap in the beginning of our presentation then i'm going to focus more on the tnits service itself and then further on we are going to talk about the challenges we tackled in the project um about talk about one proposed solution or mobile app moving and then in the end we are going to address our future plans um both in the short term and in the longer term um then at the end also my colleague here frank haver will give a presentation a a demonstration of the the two applications so the project snell at flanders is actually a cooperation between the department of mobility and public works and and the agency of roads and traffic um so here you can see an overview of the project team uh you can see the name of here frank have it he's the application owner but he um so you hear more about him uh at the end and uh my name is liam becklands i am the business analyst and also the person behind the help desk so um the project has actually uh three goals um the first one is to create one unique authentic data source for all the traffic signs in flanders so to accomplish this we first had to merge two existing databases uh the first one uh the traffic sign database of moa was uh was developed for the cities and municipalities and then you also had the road asset database of rv for the major roads so it was uh chosen to develop the road as a database of rv further and therefore we did a gap analysis to know more about the needs of the cities and the municipalities this was done in 2017 and in 2018 the fergie the new vegetable defender application was launched um secondly we want to derive a speed map for flanders and then third uh thirdly uh we want to publish this as open data so uh on the one hand for uh the tnits service for the map makers and on the the on the other hand also for uh yeah just uh for the the general public um as a gis services on the helping website of flanders so um firstly how did we derive these uh speed limits um so the the traffic signs or point locations and then uh the the road network are lines um so we we project actually these uh traffic sign locations onto the the the streets the lines um with an algorithm that actually drives as a car to the whole road flemish road network when it passes a traffic sign the attributed speed is also uh gets will be on the speed on the line and from then on uh this speed will be the case for for that line and further on as you can see in the example um the result is an automatically generated speed map which takes into account the updates uh that were done during the day and then process them each night and then the next day you can see the results uh as a no speed map um the algorithm uses a number of things so first the traffic signs for example a build up area sign that has a yeah says that uh the speed has to be 50 kilometers an hour then the road morphology of the the road network and also the implicit speed limits that are [Music] that you can find in the legislation for instance when there is no traffic sign present the speed is 70 kilometers an hour uh the result is uh for such as this but then for whole flanders so here you can see the example of the city of turnout um and then on the right uh for leopoldsburg so for example if you come from the west in here on the right you can see the orange color uh that says the speed is 70 kilometers an hour then you pass the build up area sign of leopoldsbury and from then on the speed is 50 kilometers an hour so uh all this data is is chair is shared within the tnits project uh here on the slide you can find the link to the the service itself um which was developed as a pilot project uh in the common exchange form at rosata so we took all the traffic signs in the database and and tried to map them on this format we started with only the speed limits and the traffic signs with uh with a speed limit and then we also uh took into account more traffic signs as you can see here on the slides this is only a selection you can find the whole list on our website so all this information is shared with the map makers tomtom in here as stefan already discussed so uh there only the updates are shared so you have uh the updates performed by road authorities um they uh appear in the dnits service so they can can be used by tomtom and here to process these updates um and and this will be available in the products uh so gps devices and other devices um and they will take this into account when they calculate your route from a to b um and as such this has a positive impact on the traffic safety and liability um then we also offer other uh publicly available data on um web map services and the future feature services so firstly the graphical representation of traffic signs so really and that you can see how the traffic sign looks looks like uh like it is visualized in the application itself then you have also point locations that you can use to do queries for instance and also all the derived data sets so firstly the speed limits but also other speed zones like um build up areas highway zones and residential areas for example for people who don't who don't have access to gis software they can also go to the hellbound homepage on the map you can also visualize the speed limits and the the traffic signs then what were the challenges in the product in the project so uh data quality was a big challenge uh we used two data sources so firstly the official flemish road network vehicle and where we use the morphology and the driving directions um so we don't take into account unpaved roads or private roads but if this data is not accurately available in the road network then this will cause errors also the driving directions were only available on the major roads and not for the smaller ones and this is also this a bit problematic at some locations then we use of course also the traffic sign database um where we had the challenge of getting all the municipalities and cities to update their database so for a number of municipalities the their traffic sign database is quite outdated um and they yeah they find it difficult to start updating them so we try to encourage them to do this uh through giving workshops and also we try to make on-site data collection more efficiently i will talk a bit more about that in the further presentation there are also some cities that use external software so they don't work in our application but they use [Music] other software providers and there we are talking to them to synchronize their data so we can also use it to derive or speed limit map um so to get the users on board we did workshops in each flemish province uh we talked about tips and tricks and i gave some training we also have a website for keyboard upon flanner where you can find manuals for the applications more information about our open data and also frequently asked questions and also our help desk is always available so you can send a mail with a question to virgeshbur um then um we i want to talk a bit more about our mobile app movement so we we understood from our users that they had problems to do to do on-site inspections they went on to on-site with a paper map and tried and started writing on that map which uh traffic signs were outdated in the database and which were uh okay and so on but this takes a a lot of time so therefore we developed our mobile app moving very quickly actually in a in a few months um so we focused on the minimal usable product we asked our users uh what is uh really the most essential what do you need to do these inspections and we launched a beta version so the a number of users could already test the application very quickly and the results were quite positive so we also focused on user friendliness on a mobile device because when you go on to rain you of of course want to use a tablet or even a smart smartphone so it had to be easy to use on a small screen and the big advantage of using moving is that you when you do an inspection you have this date of on-site inspection which is an important measure of data quality because of course our users of our open data they don't know which of these cities and municipalities is really updating their database or which ones are outdated and with this date of on-site inspection you get a an important measure of data quality so uh what were the results of our efforts so in 2018 the virgin board of ragnar application was launched um and you can see that a number of municipalities got on board quite quickly you also see the the hedged municipalities that they use external software and then now quite recently in 2021 you see that the map is turning blue and that more and more municipalities are starting to use our applications we also track our user amount of users with google analytics from 2019 on and you can see the rising trend in user accounts to 2020 and also for a move-in that we launched at the end of 2019 you can see that it was uh really popular in the spring of uh 2020 and we believe it it has it's also the consequence of the kovit 19 measures when a number of employees of local authorities had to do different jobs because they couldn't do their regular tasks so actually for government 19 are so it was actually a good thing for our traffic sign database then what are our future plans so we want to bridge the digital gap between on-site inspection and database input further so actually our vision there is that you take a picture of a traffic sign and it is automatically updated in our database of course uh this is uh something for the long term and uh we are not there yet but this is uh what do you want to accomplish in the future um other plans are deriving weight restrictions because we now focus on speed zones and we also want to derive other interesting data sets from traffic sites we are also integrating with other application so as stefan told you the focus is on static data sets but we are also looking into how we can incorporate dynamic road signs within the mobility data project then we also have a new application here here in flanders for making the local decision mobility decisions um publicly available within the lblod project so we want to make a link between a mobility decision by a local authority and the traffic signs that are linked to that decision and then we have also a new version of hebot and we also want to see what we can do with temporary traffic signs but that is only just starting then we also want to do a redesign of the existing application it was launched in 2018 uh as a new version of an old application so it is uh already quite uh yeah quite old and uh we want to tackle uh technical depth and improve our data model and of course keep all the users on board and then also in the tnids project we want to look into the feedback loop what can we can do with this in our application and also the new uh go to the the new uh standard um so this was uh everything for me and i want to give the floor to heart van gaaver we will give you an overview of how our applications work okay okay uh hello everyone i'm here forever i'm the application owner of moving and the traffic sign database i work for the agency for roads and traffic and in the next 15 minutes i give you a short demo of the moving app and the traffic sign database uh first i'm going to start with moving because that's the most important thing to give some inspections of the existing existing traffic signs but also uh you can add new ones uh for instance it's in fact a web app so i can use it on my browser but uh when you have chrome installed on your ios or on under your android device you can use it mobile so uh i go i zoom in i can choose here uh my background cards auto photos of grb or our regular background cards when i zoom in they will appear you see the black dots and the purple ones that's uh where i have permission to so uh the purple ones i can manage the black ones are in fact the traffic signs that are uh that's are from the local authorities so i work for uh agency of roads and highways so here this road is one of ours so i can manage the traffic signs there i can also uh uh click on one and then you see which traffic sign there is uh and located on that place so you can see here uh we have a lot a bunch of direct uh traffic signs uh i can also click on one that's not in my permission so i can see what's uh behind or in the side streets of our main road there's al also a legend so i can see what is just happened to our traffic signs right now i have done none of the control tools so all there are no recent controls uh here i can also put out the signs that not in my supervision or not in my authority and then i can start a control first of all i can check one start control and then i can choose between remove it change it or there is no action uh necessary when i put no action necessary i can still uh take a new photograph of the sign in fact so i can take one here i can take this photograph i open it and i can even remove this uh yeah it's uh on test an integration site so uh there is some problems with the photo so i can remove this photograph and at this new one i click on send and you can see there is a control um right now that needs to process in the traffic sign database also i can remove some for instance i click on remove [Music] i can even choose which one of the traffic signs will i remove i think before for instance only the under traffic uh assign here i will remove and the three other will remain so i can also add a new photo i'm not to do it right now and i send it i can remove a whole of everything and i check check all the the things here uh click to remove and send it or i can change one um i can start control i can say uh change it and i say at c 43 90 43 here 90 on my and i can take a new picture for instance i just uh select one it's not the right one but just on the demo so it's uh doesn't matter i can remove this picture because it's not the good one and i send it and then uh the last one so hey um i can add a new one so when i click in the card for instance i can take my order photos because it's a it's more uh it's better to to look where did you pick uh the new uh the new traffic sign for instance i want us to set here a new traffic sign i just click in the cards i said start new uh traffic sign and i give you my uh state of the direction which it seems when the the cars are driving so in this uh thing i it's uh that direction that i should uh set my new traffic sign i choose the side of the road in this fact right i go to control i set in my uh at for instance also a c43 with 90 and uh b9 uh 400 of uh and 90 will be 900 millimeters tall also i can add a photo and i can send it and you can see when i go back to the regular site you can see here with the cross in it it's a new uh traffic sign that i uh put into the database so uh now i i've done my work and moving so you can uh go along on the streets uh check every sign that you uh pass and then you go for the other work you open the vergers borden flanders application under so here uh yeah i'm still on tests uh on here i hope you see it otherwise i have to you see here the controls on terrain and height uh for instance i have five so uh here you see uh the user which the text which i had it i added the dates it's a new one to change to remove it you can see here the status uh the owner of the the traffic sign so this is uh district peers i see the traffic signs and where the traffic sign is located so this is the n16 in bournem and i can see here the pictures i added to the so i can go when i use the spyglass i can go to the traffic sign stats and you can see here now it's selected and i can then do the action effect and the action is in fact the green logos or that you see here so when i click on the green logo my action is done so when i select another one and reset we reselect the traffic and you see the photo is added then i choose the next one was remove one traffic sign over the bench i go are you sure you want us to remove the the plate and you see it's directly removed the others because there are three uh f33as uh so i removed one i can check it also and i click on ok and it's done then here i want to remove the total traffic sign are you sure to remove totally i say yes oh and here it says it is a temporary sign of it so i can remove it so it's normal so i can't i first have to uh set the the temporary or the plants traffic sign on the right spot and then i can remove it when i want to here i want to change one so here i set in my um see it right not right now but i can uh i set to at sc 4390 so i'll go here to the c uh section and c43 i choose to 900 no kilometers uh added and this nil it's the speeds regime is 90 so i click on ok and it will be added on the d7 it's okay i click on ok the photo is renewed and it's out of my list and then the last one is a new one that i will add so i click on the logo uh i just need to link it to the flanders road database or reagan register so it's linked on this segment of the vegan register uh then the application knows it's n16 it's on the right side i picked the the date of placement so i for the first of march for instance the authority spurs i go to my i said also it's a c43 also a 900 with 90 on it and i'm my second also automatically there's a support added to the bunch of uh traffic signs my second plate is a b9 that's a 400 so i'd it also uh then my traffic sign is completed so i can check everything i can change my diameter of the support when it's on concrete or uh just on soil i can choose here uh every everything i can manage and it's okay i just click on ok and you see when i close this one uh i added this uh extra uh there are a whole bunch of citrus 43s effort here but this is the new one i added i can also see on my dates check control and that's very important for the tnts for the for here and tomtom to know this date or last change 15 three fifteen three the fifteenth of march is today so they can uh when they uh gets the tnt service they can um filter on that and then uh took the change as uh as real so uh that's very important so uh when i go back to moving it takes a while but i when i refresh and i go uh back to the place where i did some uh it's about here i think normally i can find a little more normally they but it takes a while but normally all the the recently changed uh traffic signs will be with a full circle around it so you know you have recently uh checked these ones and you have to check all along the where there are no recent controls or checks on it um that's in brief what you can uh here in the gui you have you can do the same somebody muted me i think so you have here in the gui you can do the same things directly on the database so you don't have to use moving but it's a very simple uh thing to maintain or to update your traffic sign database uh a quick review to uh the tnats rest data sets so you see uh the links will be provided on links uh so you here see the that are already a lot of uh rosetta data sets i mean i click one you can see here uh how it's uh give to the uh tomtom and here's so they can read it out you see here for instance uh an added traffic sign on the 14th of march it was inspected the second of march and then the after in the traffic sign database it's added on the 14th of march and you see it's a fixed traffic sign start of motorway and the maximum speed limit is 120 kilometers an hour so the dna service it translates the data to the rosetta specs and you can see it right here uh we also have data x-ray to a date x2 via the vercarecentrum.be we have some data extra two uh data and uh lint tools uh all everything is uh put on here pins so okay you can uh find its uh mobility transport of lens uh the fed cares button flanders so you can see the locations of the the traffic signs or the the raft speed limits when you use our open data link rvms you can also check out the derived speedway zones or uh all the other zone 30 or zone 50 and all the other ones so that's uh my demo about 50 minutes 20 minutes perhaps so over to the questions the first question is will other map makers also be involved for instance google maps ways open street map um we already talked to waze um and yeah there are their viewpoint was that they find their input from the community very important so they they know that our data exists but they um as far as we know we they are not really using it because they think their own information is is a yeah from the best quality um how how they deal with uh very varying data quality yeah that um that is an important uh point um and we we try to deal with it to uh by giving them access to the the dates so the date of last uh of the inspection on terrain and also the date of the last edit um and also they only get the updates uh that are done so they don't uh really need to take into account all the the old data so they only get the the changes the updates and we we think that these updates are are always uh yeah better than the the old data yeah steven it's in fact yeah it's a tnts service but it was before perfectly the rosette specs um yeah the crowd source data that is something we we want to look into but for our process with our applications the the bottleneck is the the cashbot of lander application because in moving you can do these inspections you can say what is wrong um on terrain but uh someone has to go uh over all these inspections to really make the changes in the database so if we would make moving publicly available the the people at the local authorities would have a very large list of inspections to to cover but um we we want yeah to take this into account and try to to look at how we we can solve that but it's a very interesting uh thing to look at yeah of course i think the last question probably stephen yeah so currently we have no contacts with the brussels or walloon authorities we have tried a number of times reaching out to them and well bottom line is that there is not always the possibility to work on setting up tnits service for many different reasons it could be that the priority is on dynamic data it could often there is an issue on resources often there is an issue on source data and tools bottom line is we yeah it's it has not realized to materialize them we're of course very welcome um to um explain tnits to them to brussels and balloon authorities to educate them to convince them of the of the benefits that setting up these services has for the authorities themselves that's important and of course the benefits for for their citizens [Music] it's it's a pity but i i would also say it's not unique to the belgian situation we have in europe other regions where the responsibilities and the i should say commitments are are diverse only in a few countries especially in the nordics and you have like these kind of unique federal road administrations and that's a one-stop shop and that's of course the ideal situation is if you think about germany the responsibility is distributed over provinces or bundeslanders as they're called and there it's very difficult to introduce tnits on that level um that is now i understand in germany a federal organization that's been put into place for the highest road classes motorways and we hope that we will cooperate with them in the future to set up this type of data exchange also the situation is problematic in in france and italy for the rest i mean typically the smaller the country is the easier it is to [Music] do to get things moving okay are there any questions left i i think we covered them all maybe i can come back on tim's question on how to how do map makers deal with varying data quality um i've worked for one of the leading map makers for almost 20 years so i'm well positioned to to give an answer on that so typically there is like a system in place that evaluates different sources of changes either from floating car data from authoritative data such as tnits from other type of gis data from active user input people complaining like okay the speed limit for my road is completely wrong let's put it on 50. so that happens so there's a system in place which um assigns values to different input streams and as it is now uh authoritative data such as tnit yes can trump other types of data so there's kind of a trumping mechanism in place and finally depending on certain thresholds or whether certain thresholds are met or not met an automatic update is generated and the map is updated if a certain threshold of confidence is not met then it goes to a manual review stream and then operators evaluate what is the best source to rely on to make an update if there is a decision that i mean the input information is not of sufficient quality then that can be um [Music] fed back to the the provider either a person actively submitting a change request or the authorities as i've mentioned before for floating car data of course that that doesn't work you cannot send back uh an observation from a car uh that that's that chain is not uh is not implemented and that's also the interesting thing about the feedback loop i think and that we can give feedback from the map makers to the the authorities for example so that is something we really want to look into so currently in pilot phase we have provided so we the map makers have provided feedback related to successful matches of location references or unsuccessful matches [Music] that's that's probably the most important feedback information on mid and longer term this feedback can also act as a way to inform authorities of changes on the network that is observed from an older source than what is you know what they mentioned as a potential change but that's part of the um ongoing discussion with the mapping industry and authorities in europe okay okay are there more questions or [Music] maybe we can conclude this session i don't see any questions coming in so i suggest that we conclude this session as lien said i want to thank yetling and stefan for this session and i will end the recording now but i will keep the room open for two more minutes if there are maybe um any questions coming up in the chat good morning everyone you
