Re: [sumo-user] Routing based on traffic density

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Yes. routeSampler should work for this.

Edge-data files can be created manually with netedit and also from text-based formats of detector data.

However, if your density data comes from a database or some other kind of format the easiest solution is to write a small data-transformation script.

You only need to set on count attribute per edge and time interval. and the name of the attribute can be set with a routeSampler option.

Hello,

 

I have a question regarding edge based routing.

I have access to traffic density data on edge granularity in hourly steps and would like to know if there is an implementation in SUMO,

which generates routes from this kind of data or upscales a subset of routes (I can get around 5% of the actual routes) to derive the wanted density?

 

I thought about using routeSampler.py, which uses routes and edge-count data as input parameters

Is this an attempt, which should work?

 

If yes:

I couldn’t find information about an edge-count data file (--edgedata-files), which isn’t dumped by SUMO, but just created from traffic density data.

Is  it possible to create such files just from density data?

 

The information i gathered to get an understanding of the routeSampler.py is mostly based on these documentation pages:

https://sumo.dlr.de/docs/Demand/Routes_from_Observation_Points.html#introduction

https://sumo.dlr.de/docs/Simulation/Output/Lane-_or_Edge-based_Traffic_Measures.html

https://sumo.dlr.de/docs/Tools/Turns.html#turn_count_data_format

 

Thank you for your help.

Regards,

Benedikt Kaubrügger
