Re: [sumo-user] Retrieve route edges for a trip with traci

[Kevin Malena <kevin.malena@xxxxxxxxxxxxxxxx>]

Thank you!

 

Since I want to integrate this into my simulation, I will try to implement a function in matlab to define the client order because this is mandatory and not yet done.

 

Cheers,

Kevin

You can load the trip into duarouter and read the resulting route output. Likewise you can load the trip into sumo and write the full route using option --vehroute-output.

Also, consider using another traci client to call findRoute.

Hey,

 

is there a chance to get the edges for a trip which is defined by start and end edge? I wanna use traci (traci4matlab) but findRoute doesn’t work?

I tried to find the (probable) parsing mistake, but wasn’t successful so far.

For exemplary edges edge_a and edge_b the command and the error are:

 

Command:

traci.simulation.findRoute('edge_a,' edge_b ','passenger')

 

Error:

Index exceeds array bounds.

 

Error in traci.Storage/read (line 22)

                                               value = this.content(oldpos:this.pos-1);

 

Error in traci.Storage/readString (line 59)

            value = char(this.read(len));

 

Error in traci.simulation.readStage (line 17)

intended = result.readString();

 

Error in traci.simulation.findRoute (line 45)

route = traci.simulation.readStage(result);

 

The same error occurs in the provided test function traci_test2.m if u uncomment line 802 (route = traci.simulation.findRoute('1i','2o') )

 

 

 

In https://sumo.dlr.de/wiki/Demand/Automatic_Routing it says that the fastest route is chosen and in the sumo-gui the route can be made visible by “show current route”.

Probably someone knows a walkaround.

 

Thanks,

Kevin
