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

[Kevin Malena <kevin.malena@xxxxxxxxxxxxxxxx>]

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
