Hello, SUMO community,
I would appreciate any help on my issue.
In my scenario, I want vehicles to stop for several seconds when they enter a specific edge and then resume driving. For that, I am using TraCI with the ‘setStop’ function and a dictionary to store the ‘hasStopped’ value for vehicles that have already stopped.
But after making a stop, the vehicle does not resume driving and the simulation runs indefinitely. What could be the problem here?
Best Regards,
Danil
Here is my code:
class
EvaluationVehicle:
"""Data container class for the individual vehicles. Stores all relevant data for the Evaluation vehicle-related."""
def
__init__(self,
id, type):
self.id = id
self.type = type
self.hasStopped =
False
def
run():
start = datetime.now()
print(str(datetime.now()))
# create empty dictionaries to store data
vehicleMap = {}
# begin and end times of the simulation in seconds from 00:00
begin =
0
end =
4000
seed =
1
# set parking entrance edge ID and parking exit edge ID
pEntrEdgeID =
"988716348.13"
nextToEntryID =
"988716348.13.3"
# start Traci
traci.start(["sumo-gui",
"-n",
"osm_1.net.xml",
"-r",
"osm.bicycle.trips.xml",
"-a",
"parking.add.xml",
"--step-length",
"0.25",
"--delay",
"250",
"--parking.maneuver",
"true",
"-b",
f"{begin}",
"-e",
f"{end}",
"--seed",
f"{seed}"])
while
traci.simulation.getMinExpectedNumber() >
0:
traci.simulationStep()
# get the list of vehicles currently in the simulation
vehIdList = traci.vehicle.getIDList()
# loop over each vehicle in the simulation
for
vehicle_id
in
vehIdList:
vehEdgeID = traci.vehicle.getRoadID(vehicle_id)
vehType = traci.vehicle.getTypeID(vehicle_id)
# check if the vehicle ID is not in vehicleMap
if
vehicle_id
not in
vehicleMap:
# if not, create an EvaluationVehicle object for the vehicle and store it in vehicleMap
vehicleMap[str(vehicle_id)]
= EvaluationVehicle(str(vehicle_id),
str(vehType))
# If the vehicle enters the edge and has not stopped before,
stop it for
a specific
time
if
vehEdgeID == pEntrEdgeID
and not
vehicleMap[str(vehicle_id)].hasStopped:
stop_time =
2
traci.vehicle.setStop(vehID=vehicle_id,
edgeID=nextToEntryID,
pos=1,
laneIndex=0,
duration=stop_time,
flags=2)
vehicleMap[str(vehicle_id)].hasStopped =
True
# close simulation
traci.close()
