Re: [sumo-user] How to collect Junction data from Links

# import the library
import sumolib
# parse the net
net = sumolib.net.readNet('myNet.net.xml')

# retrieve the coordinate of a node based on its ID
myJunction = net.getNode('myJunctionID')
incomingEdges = myJunction.getIncoming()
outgoingEdges = myJunction.getOutgoing()

How do I use sumolib? I saw the documentation but it didn't help me at all

See https://sumo.dlr.de/docs/Simulation/Output/index.html#values_for_junctions

Also, you can use sumolib to retrieve all edges around a junction: https://sumo.dlr.de/docs/Tools/Sumolib.html (then use this to aggregate travel statistics on edges).

Hello, I have a python code to handle Multi-agent Reinforcement Learning using SUMO as a microscopic traffic simulation. It collects data from a .sumocfg file and generate .csv file with Step, Link, Running Vehicles, Occupancy and Travel Time parameters from the simulation.

 

I'm trying to modify it by including a Junction parameter and aggregate and ordenate the link parameters by junction.

 

How can I access a Junction with .getEdge()?
