[sumo-user] How to use the function getCollidingVehiclesNumber()

[Zhiqiang Hu <hzq950419@xxxxxxxxx>]

Hi sumo-users,

when I wrote "print(traci.simulation.getCollidingVehiclesNumber())" into my code, I got this error:

  Traceback (most recent call last):

  File "runner.py", line 173, in <module>

    run()

  File "runner.py", line 137, in run

    print(traci.simulation.getCollidingVehiclesNumber())

  File "/home/hzq/sumo/tools/traci/_simulation.py", line 187, in getCollidingVehiclesNumber

    return self._getUniversal(tc.VAR_COLLIDING_VEHICLES_NUMBER)

  File "/home/hzq/sumo/tools/traci/domain.py", line 115, in _getUniversal

    self._cmdGetID, varID, objectID)

  File "/home/hzq/sumo/tools/traci/connection.py", line 127, in _sendReadOneStringCmd

    return self._checkResult(cmdID, varID, objID)

  File "/home/hzq/sumo/tools/traci/connection.py", line 155, in _checkResult

    result = self._sendExact()

  File "/home/hzq/sumo/tools/traci/connection.py", line 105, in _sendExact

    raise TraCIException(prefix[1], _RESULTS[prefix[2]], err)

traci.exceptions.TraCIException: Get Simulation Variable: unsupported variable 0x80 specified

Could you please tell me how to fix it ?

Thanks in advance.

Best regards,

Zhiqiang
