Re: [sumo-user] How to get the turning behavior of the vehicle?
Thanks again for your reply,

I have seen https://sumo.dlr.de/docs/Tools/Sumolib.html#parse_vehicles_and_their_route_edges_in_a_route_file  when I was querying sumolib
But it is more inclined to disassemble routing files and coordinate conversion. I want to know the turning direction of the route

There is a getDirection() function in the class Connection of sumolib, but what I don’t understand is how to use the routing path or edge as input to determine the turning direction. (https://sumo.dlr.de/pydoc/sumolib.net.connection.html)

Many thanks,
Yun

Thank you for your reply
I read some documents of sumolib but still don't understand how to use it

ex: dir = fromEdge.getConnections(toEdge)[0].getDirection()  
The getConnections is a function of sumolib.net.edge.Edge, but I don’t know how to set attributes like fromedge and toedge and then get their direction
Could you please explain more?

Many thanks,
Yun

You can use sumolib to read the turning direction for each network connection. All you need to do is parse the route file and look up a connection for each pair of successive route edges: dir = fromEdge.getConnections(toEdge)[0].getDirection()

Hello,
I want to record the left and right turn behavior or the number of turns of the vehicle in a route
Do Traci or other function libraries provide similar functions?

Many thanks,
Yun
