Thank you for your kind response.
1. I have implemented the first option successfully for different vtypes.
2. By Traci I used the following code. It is working successfully for a
single vehicle and will work for multiple vehicles.
If the number of vehicles increases and we want to check for each vehicle,
then this code will have a lot of redundancy.
Can you suggest me some changes so that I will be able to improve the code?
def run():
# intialisation of variable
steps = 0
edge_id ="e0"
while steps < 3000:
traci.simulationStep()
#to get the edge id
edge_id0 = traci.vehicle.getRoadID("0")
edge_id1 = traci.vehicle.getRoadID("1")
#if the edge id is e1 then change vtype to d
if(edge_id0 == "e1"):
traci.vehicle.setType("0", "d")
if(edge_id1 == "e1"):
traci.vehicle.setType("0", "d")
#if the edge id is e1 then change vtype to c
if(edge_id0 == "e2"):
traci.vehicle.setType("0", "c")
if(edge_id1 == "e2"):
traci.vehicle.setType("0", "c")
steps+=1
traci.close()
