Re: [sumo-user] 3D Opendrive roads & 3D traffic synchronization in Traci

[Chris Weinhaupl <chrisweinhaupl@xxxxxxxxx>]

I am just looking at elevation for my tunnel simulation because I would like to add the concept of ramps.

Where am I adding the z coordinates to a 'junction' or 'edge' ?

I am adding z in netedit?

Thanks

1. Yes.  All geometries support an optional z-coordinate which will be set when the input data provides it. See https://sumo.dlr.de/docs/Networks/Elevation.html

2. moveToXY currently does not support setting a Z coordinate. If there are multiple roads on top of each other, you could specify the target edge id (which you could figure out via sumolib.net.getNeighboringEdges (https://sumo.dlr.de/docs/Tools/Sumolib.html#locate_nearby_edges_based_on_the_geo-coordinate) and comparing the edge geometry to the target z-coordinate

pitch angle can be retrieved via traci.vehicle.getSlope, yaw via traci.vehicle.getAngle  and roll-angle is not modelled at all.

Hi all,

I had a couple of questions regarding SUMO roads and 3D traffic synchronization using Traci

1. Can we import a 3D opendrive road into SUMO? does SUMO support 3D roads in general?

2. I noticed in TraCI API, you can set a car's position using moveXY function and specify its heading angle. I was wondering can we send 3D car's state to SUMO? (XYZ position and RPY angles). Also how can we get 3D angles from SUMO (e.g pitch angle when car is going up a bridge)

Thanks in advance

Regards,

Hamid
