Failure of Vehicle.setRoute by startEdgeID (junction) in TraaS

[YenKang]

When I execute setRoute function and the current Edge of the vehicle is the junction whoes ID is ":cluster_1240288780_2365426109_0", the system would crash due to the error of route arrangement.

The sumo console showd the error message

Warning: Invalid route replacement for vehicle '1'. No connection between edge '381410220#2' and edge ':cluster_1240288780_2365426109_0'. Error: Answered with error to command 0xc4: Route replacement failed for 1 Error: tcpip::Socket::recvAndCheck @ recv: peer shutdown Quitting (on error).

My codes

String vType ="truck"; 
double depart = 0.0; 
int routingMode = 0;
String startEdgeID = ":cluster_1240288780_2365426109_0";
String endEdgeID= "30438916#0";
SumoStage stage = (SumoStage)conn.do_job_get(Simulation.findRoute(startEdgeID, 
    endEdgeID, vType, depart,routingMode));

LinkedList<String> v1_route_from_Junctions_to_validEdge = new LinkedList<String>(); 

for (String edge :stage.edges){ 
    v1_route_from_Junctions_to_validEdge.add(edge); 
}

System.out.println("v1_route_from_Junctions_to_validEdge:"+ v1_route_from_Junctions_to_validEdge);
conn.do_job_set(Vehicle.setRoute("1", stage.edges));

My outpot console

currentEdgeId::cluster_3846116384_5209464726_10

converted_road_Edge::cluster_3846116384_5209464726_10

it.polito.appeal.traci.TraCIException: SUMO error for command 196: Route replacement failed for 1

My questuion

Is any solution for us to setRoute by "junction"?

You can give the edge following the internal edge as first edge of the routing. There is currently no way to find this edge via traci / traas. You will need to parse the network or use sumolib to do so.

You should also be able to retrieve the subsequent edge using lane.getLinks(internalLaneID)
