Re: [sumo-user] Turning vehicles

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

The trivial solution would be to run a simulation one or more steps into the future and use that as an estimate.

However, you can also use traci to retrieve the geometry of the turning lanes and then compute the position along that length.

futureLanes = traci.vehicle.getBestLanes(vehID)[traci.vehicle.getLaneIndex(vehID)][-1]

x,y,z = traci.simulation.convert3D(

   traci.lane.getEdgeID(laneID), int(laneID[-1]), offset))

Note, that you need to compute laneID and offset by advancing along futureLanes until the intended distance is covered.

Jakob

We are a university group doing a project on modeling and verification of
autonomous vehicles in intersection. To do this we need to calculate the
future positions of a vehicle. This is easy when going straight as we only
need to update the x or the y coordinate of the vehicle according to their
speed. However, when turning the function is non-linear and therefore harder
to calculate. We were wondering if a function for calculating the position
of the vehicle exists that we can use?
