- 4. Goal of the project Section 1
- 5. FME INNOVATION DAY 2025 Project Overview ● Pilot Study on F45 ● drivenBy provided data with mobile mapping
- 6. FME INNOVATION DAY 2025 Meet the F45 ● Access? ● Priority on intersections? ● Speed limits? Conform with design principles? Homogeneous?
- 7. Section 2
- 8. FME INNOVATION DAY 2025 Available data ● Cycling network provided by OVL ● Traffic signs collected by drivenBy ○ Cycling along F45 with 360° camera ○ Image recognition linked with GPS tracker
- 9. FME INNOVATION DAY 2025 Data selection – 3 Models 1. select candidates and create bounding boxes 2. classify type/code of traffic sign 3. read text on signs Result : dataset of traffic signs with codes, orientation and location
- 11. FME INNOVATION DAY 2025 Steps to undertake 1. Identifying intersections of F45 with road/rails 2. Creating a topological network 3. Linking priority signs to intersections 4. Linking speed/access signs to segments
- 12. FME INNOVATION DAY 2025 Identifying intersections of F45 with road/rails ● Intersection with road segment (black), WRL (yellow) (GRB) ● Not under an engineering structure (pink) ● Duplicate and quality filtering using a custom made transformer Green points : intersections. Blue lines : cycling network, Black lines : road network Pink polygon : engineering structure
- 13. FME INNOVATION DAY 2025 Creating a topological network ● Filtering illegal directions ● Needed for priority rules ● Used for inheritance and speed zones (later more) In the leftmost intersection, segment 306 is incoming and 232 outgoing.
- 14. FME INNOVATION DAY 2025 Linking signs to intersections and segments ● NeighborFinder to link signs to closest segment ● For speed and access signs this is sufficient ● For priority signs : via topological network We know the +B1 sign is linked to this intersection because 79 is incoming and 45 outgoing (in positive direction). The opposite is true in the negative direction.
- 15. FME INNOVATION DAY 2025 Speed/access zones ● Sign applies to multiple segments ● Start and end segment are known ● We need to find a path, how? All segments between these two signs must be accesible for cyclists, have a maximum speed of 30km/h and cyclists have priority at each intersection.
- 16. FME INNOVATION DAY 2025 Pathfinding ● Using the topological network ● Constructing a tree to find a path A zone has been identified between a ZF111 and ZF113 sign including multiple segments. The line is green which means that the speed limit is 30km/h.
- 17. FME INNOVATION DAY 2025 Inheritance ● Same idea as for the zones ● Sign is valid until next ‘large’ intersection ● Inheritance of information across ‘small’ intersections C3+M11 : Access prohibited for everyone except cyclists and speedpedelecs. Linked to segment 213 but bestows its properties to segment 359.
- 18. Section 4
- 19. FME INNOVATION DAY 2025 Layers ● Intersections ● Priority symbology ● Markings ● Speed zones ● Speed ● Traffic signs ● Problem areas All the layers that are availble in the project. For data control there are a few layers which are mainly used to correct the source data and do a second or third run after corrections.
- 20. FME INNOVATION DAY 2025 Example 1 ● B15a give priority on the next intersection ● Speed is 30 ● Shark’s teeth (yield lines) on intersection for cars and tack coat in both directions for cyclists B15a : Priority at the next intersection.
- 21. FME INNOVATION DAY 2025 Example 2 ● Along positive direction ○ cyclists have access (D7) ● Along negative direction ○ access is forbidden for everyone (missing undersign or M3bis on wrong location) ○ must give priority to traffic due to the B1 sign B1 : Must give priority, D7 : Mandatory for cyclists to use the cycling path, C1 : Forbidden direction for everyone, M3bis : Main sign not applicable for (motor)cycles.
- 22. Section 5
- 24. FME INNOVATION DAY 2025 Inventory ● Crossings ○ Type - Wegenregister vs OSM ○ Design ● Traffic signs ● 360 images connected to our GIS environment ● control
- 25. FME INNOVATION DAY 2025 Derived characteristics ● Process ○ Interesting but room for improvement ○ Approach to zones ● Map/statistics ○ More reliable for cycling tracks than in mixed traffic ○ Priority ○ Speed, access: high percentage of unknown ○ Sensitive to errors in source data/ relation between signs and segments
- 26. FME INNOVATION DAY 2025 Derived characteristics ● Problem areas ○ Most problems are data-related ○ Some are valuable
- 27. FME INNOVATION DAY 2025 Future ● Room for improvement - pilot ○ Not ready yet for presentation to local governments ○ Not ready for extension to complete network ● Reference data set ○ To be compared to other data sources ● Define essentials
