[sumo-user] Dead End - changeTarget/MoveToXY issues

[Paul Fierro <paulfierro@xxxxxxxxxx>]

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
