structurally similar to the implementation of getCollidingVehiclesNumber() and getCollidingVehiclesIDList()

Hi Jakob,
I use emergency_stops = traci.simulation.getCollidingVehiclesNumber() to get the emergency stops,but it returns 0 as below.I would like to know why the simulation outputs can count the emergency stops but the python interface can't.I suggest to add it to the latest development version of SUMO.

The command wasn't yet implement in the TraCI protocoll (server side), That is why none of the clients can provide the function yet.

@HZQ950419 You have to download the latest development version. (traci.simulation.getEmergencyStoppingVehiclesIDList()) It appears that our nightly build process is currently out of order. You can try to download http://sumo.dlr.de/daily/sumo-msvc12x64-git.zip tomorrow or build sumo yourself on the operating system of your choice: http://sumo.dlr.de/wiki/Developer/Main#Build_instructions
