Re: [sumo-user] Edges to TAZ assignment.

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

OD2TRIPS converts an OD-Matrix to trips by sampling from edges within the districts (TAZ). An OD matrix captures information about traffic flow between different areas of the city. If you have only a single area defined, than the process degenerates to that of randomTrips.py

Put differently: the existence of an OD-Matrix pretty much implies a pre-existing zone concept and this should be reflected in the OD2TRIPS input.

Hello SUMO Community,

 

To use to OD2Trips, the documentation says edges has to be mapped to TAZs. (https://sumo.dlr.de/docs/Demand/Importing_O/D_Matrices.html)

I am trying to use a whole city’s road network as the network file (downloaded from openstreetmaps as osm and converted to net file via netconvert, doesn’t have district information built in) and OD matrix that includes origin destinations all around the city.

Can I assign every edge in a network file to a single TAZ ?

OR

Could anyone explain me why TAZs are important for OD2Trips to work ?

 

Thanks and regards,
