Re: [sumo-user] Extremely High Values Returned by traci.edge.getTravelti

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

getTraveltime computes its result based on the average vehicle speed on the edge. If all the vehicles are standing while queued at a traffic light, high values result.

You could either compute your own minimum travel time based on the edge length (sumolib) and your own assumptions regarding minimum average speed or you could access the smoothed travel times computed by the rerouting device. For this to work you need to equip a vehicle with the device and then call

traveltime = double(vehicle.getParameter("vehID", "device.rerouting.edge:edgeID"))

For details on how to configure the averaging algorithm, see http://sumo.dlr.de/wiki/Demand/Automatic_Routing#Edge_weights

Hello,

When using the function traci.edge.getTraveltime(), the returned value is sometimes extremely large. Is there anyway around this?

Thanks
