Hi Michael,
Thank you for the clarification.
I have another doubt regarding the initiation of the scenario.
The scenario includes,
1. I have 4 vehicles in a straight road going from west to east with 2 lanes.
2. Movement of vehicles on both the lanes are in west to east direction.
3. The scenario starts with 2 vehicles on lane 0 and 2 vehicles on lane 1.
So my question is how can I incorporate the above mentioned (Point 3) in sumo.
In which file should I make the necessary changes.
I tried changing route file by adding departLane="random" , but still all the
vehicles start from a single lane and I can only see one lane. Also I have
already created type file and mentioned numLanes="2".
Best Regards,
Sujit Sharan

You could use traci.vehicle.moveToVTD which accepts precise coordinates
and an angle as input. You cannot set lateral velocity though, you would
need to update the position yourself in every step.
