Re: [sumo-user] Validation for Traffic Phase

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

there is a simple case and a complex case.

In the simple case:

 - each traffic light controls a singe network junction

 -  the traffic light has the same id as the junction

 - each index of the traffic light state corresponds to a single lane-to-lane connection and those indices have not been change from their default values

If these conditions are met, you can use sumolib function net.getNode(nodeID).areFoes(index1, index2) for each pair of indices that have a 'G'.

see https://sumo.dlr.de/docs/Tools/Sumolib.html

In the complex case you have to establish the correspondence between traffic light indices and junction indices. This can be done with the help of

sumolib.net.getTLS(tlsID).getConnections()

sumolib.node.getLinkIndex

Alternatively, you can use traci:

- use traci.trafficlight.getControlledLinks to find the internal lane(s) controlled by a given traffic light index (called viaLane in the result object)

- use traci.lane.getInternalFoes to find which internal lanes are in conflict with each other

regards,

Jakob

Hi,

my name is Abdullah. I am using SUMO in my thesis. I wanted to know if there is a way to validate that a junction's traffic phase like this 'GrGr' phase (for a simple four way intersection where cars can only go straight) is correct but 'GGGr' is incorrect. I have not found a function in traci that provides sufficient information to be able to deduce this.

Is it possible to do this? Also is it possible to get topological information like coordinates of a lane?

Thank you for your help.
