Re: [sumo-user] Building Walking Areas from Polygons

[Sasan Amini <aminissn@xxxxxxxxx>]

Thanks for the answer Jakob. I already tried --ignore-errors but I still get errors regarding number of lanes and speed:

ERROR 1: PROJ: proj_identify: Cannot find proj.db
ERROR 1: PROJ: proj_create_from_database: Cannot find proj.db
Error: Required field 'nolanes' or 'speed' is missing (add fields or set option --shapefile.use-defaults-on-failure).
Error: Available fields: material parents level note Shape_Leng Shape_Area parents_2 crossing
Error: No nodes loaded.
Quitting (on error).

Netconvert supports shapefile input (https://sumo.dlr.de/docs/Networks/Import/ArcView.html)

If you set option --ignore-errors, it will tolerate missing fromNode and toNode ids.

Nodes will be added automatically and and nodes within a configurable distance (shapefile.node-join-dist) will be merged.

However, this will only build sidewalks of fixed width.

There is currently no code that ties together shapefiles with custom walkingarea shapes (https://sumo.dlr.de/docs/Networks/PlainXML.html#walking_areas)

Jakob

Dear all,

I have a question regarding pedestrian modeling. I have my sidewalk infrastructure in a very accurate shapefile and would like to build a pedestrian/walking network out of it. IS it generally possible to do such conversion using NETCONVERT? Obviously, I don't have nodes or numLanes etc. in this shapefile. 

I would appreciate any suggestions.

Best,

Sasan
