Hi,
you can use traci.lane.getAllowed("lane id") to check if the given lane allows
your vehicle type (see
https://sumo.dlr.de/docs/TraCI/Lane_Value_Retrieval.html). With
traci.lane.setAllowed("lane id") you can change the vehicle types that are
allow in the given lane (see
https://sumo.dlr.de/docs/TraCI/Change_Lane_State.html).
I'm not sure if it Is the best solution, but you could add turnarounds in your
net to avoid dead ends and allow the vehicles to turn around in the next
junction. You can do this with netconvert:
netconvert -s yournet.net.xml --no-turnarounds false -o newnet.net.xml (see
https://sumo.dlr.de/docs/netconvert.html)
Regards,
Giuliana

Subject: [sumo-user] Dead End - changeTarget/MoveToXY issues
I want to set up the problem properly and then highlight the issue I am having.
I have a series of people that need to be picked up by a busroute, and I see
numerous capabilities to handle bus routes that I am not using as of yet. What
I am doing now is I am visiting a RoadId or route segment near the person and
when the vehicle arrives the person will board and then the bus will change its
Target to a new destination target to the next customer in the route.
at times this fails because the person is on a road segment that does Not allow
vehicles to travel down, like local road/rural road/private road. I have
gotten around this by writing a radius alternative algorithm using your api too
discover a nearby road that does allow vehicles. This works fine.
Occasionally when the vehicle arrives to a person's nearby location, the route
ends on a dead-end route. In this case changeTarget does not turn the vehicle
around, instead what may be an available destination is failed, as well as I am
sure the original problem which some of the edges are not allowing vehicle's
may also be failing.
Simply, I have tried moveToXY as a way to re orient the vehicle at angle -= 180
degrees. This would seem to be needed a prerequisite to calling changeTarget.
This is my current thinking and strategy. But somehow, I am calling movetoXY
in manner that does not work. It must be in lane_index, edge_id, angle, xv, yv
values. I need to turn this vehicle around so a change Target can take it to
the next customer.
Lastly, is there a way to check if an edge allows vehicle or not, and
potentially can that be changed.
tmp = traci.simulation.convertRoad( XcnvTry, YcnvTry )
destEdgeId = tmp[0]
lane_index = tmp[2]
nptabu = np.array(tabu)
stateNotTabu = StateNotInTabu([destEdgeId], nptabu)
if stateNotTabu:
tabu.append([destEdgeId])
print('Size of Tabu List:', len(tabu))
try:
traci.vehicle.changeTarget(prid, destEdgeId )
#done = True
headingToX = XcnvTry
headingToY = YcnvTry
initialChampionFound = True
dtry = distEuclid( XcnvTry, YcnvTry, XCustcnv, YCustcnv )
if dtry < chDfrmOrig:
chEdgeId = destEdgeId
chDfrmOrig = dtry
chXtry = XcnvTry
chYtry = YcnvTry
print( "NEW CHAMPION - Base Radius stRadius:", stRadius ,"
cnt:", cnt, " ch:", chDfrmOrig, chXtry , chYtry )
if circularMove:
break
except:
pass
return chEdgeId, chXtry, chYtry, cnt
Could not make Bold work:
# route_id = traci.vehicle.getRouteID(prid)
# edge_id = traci.vehicle.getRoadID(prid)
# lane_index = traci.vehicle.getLaneIndex(prid)
# position = traci.vehicle.getPosition(prid)
# xv = tuple(position)[0]
# yv = tuple(position)[1]
# angle = traci.vehicle.getAngle(prid)
# angle -= 180.0
#
# fndMinus = edge_id.find('-')
# if fndMinus >= 0:
# edge_id = edge_id[1:]
# else:
# edge_id = '-' + edge_id
#
# traci.vehicle.moveToXY(prid, edge_id, lane_index, xv + 50, yv + 50, angle,
keepRoute=2)
# try:
# traci.vehicle.changeTarget(prid, destEdgeId)
# # done = True
# headingToX = XcnvTry
# headingToY = YcnvTry
# initialChampionFound = True
# dtry = distEuclid(XcnvTry, YcnvTry, XCustcnv, YCustcnv)
# if dtry < chDfrmOrig:
# chEdgeId = destEdgeId
