Re: [sumo-user] TraCI rerouteEffort output behaviour

[Toby Cannon <tobycannon50@xxxxxxxxx>]

I think in my case the latter explains this behaviour, thanks for your help.

Within this file a few of the vehicles that don't have reason="traci:rerouteEffort" seem to have reason="device.rerouting" listed a few times, indicating that during the trips they are being rerouted multiple times. I have a couple of questions:

1) Is this rerouting them based on effort? If not, is this possible?

2) What's causing the vehicles to reroute? Are there set trigger points? I have read the web page on automatic routing and have not set / changed any of the rerouting settings.

If anyone could shed some light on how this works I'd be very grateful.

here are things that might explain the symptoms

- if the departure times are fractional (can easily happen when running randomTrips.py) wheras the simultion steps are integer (the default) then the equality condition will often fail

- if the original route equals the route computed by rerouteEffort, no rerouting will take place and thus no trac:rerouteEffort is recorded

Hi SUMO users,

I'm attempting to reroute all vehicles by effort on the first step they enter the simulation.

I have a list of 273 trips, however, in the vehicle output file only around 50 or so are showing reason="traci:rerouteEffort" in their route element.

A basic version of my code is below:

tripInfo is an array consisting of id and depart times for each vehicle [[id, depart], [id, depart]...]

(I've checked tripInfo and there are 273 elements in this as there should be)

while traci.simulation.getMinExpectedNumber() > 0:

        for vehicle in tripInfo:

            if (vehicle[1] +1 == traci.simulation.getTime()): 

                traci.vehicle.rerouteEffort(vehicle[0])

        traci.simulationStep()

traci.close()

Does anyone have any idea on why reason="traci:rerouteEffort" is not being shown for all 273 vehicles?

Many thanks,

Toby
