How to implement Lane Change Models using VEINS?

[kh...@ismll.de]

Hi All,

Is there any method in VEINS (Traci) for implementing a default lane change scenario? 

Any help will be appreciated.

thanks,

Umer

If you want to change the lane change model: you will have to modify the
road traffic simulator.

If you only want to temporarily force a vehicle to a certain lane: the
SUMO TraCI documentation has a page on that at. See [1]

Best,

Christoph

Thanks Christoph,

Yes, I can control the vehilce's current lane by implementing a customized policy.

But does Veins has a default lane-change policy or model ? like MOBIL or Incentive criterion based lane changes?

Yes.

Please see the SUMO documentation.

Hello Umer,

You need to modify the TraCICommandInterface.cc file and the TraCICommandInterface.h file. 

TraCICommandInterface.cc

void TraCICommandInterface::Vehicle::changeLane(uint8_t laneIndex, int32_t timeGo) {
    uint8_t variableId = CMD_CHANGELANE;
    uint8_t variableType = TYPE_COMPOUND;
    int32_t count = 2;
    uint8_t laneIndexT = TYPE_BYTE;
    uint8_t timeT = TYPE_INTEGER;
    TraCIBuffer buf = traci->connection.query(CMD_SET_VEHICLE_VARIABLE, TraCIBuffer() << variableId << nodeId << variableType << count << laneIndexT << laneIndex << timeT << timeGo);
    ASSERT(buf.eof());
}

TraCICommandInterface.h

void changeLane(uint8_t laneIndex, int32_t timeGo);

You can call the function in the application, like BaseWaveApplLayer.cc file. Something like that:
traciVehicle->changeLane(0,5000); //changeLane(laneIndex,time)

Hi Wellington, 

Can you explain what the laneIndex is, and if I want to change the vehicle from the current lane to the left, how can I get the laneIndex? I know there is a vehicle method called getLaneIndex. But using the current vehicle, I can only get the current laneIndex, how could I get the left laneIndex? Thanks.
