Re: [sumo-user] Change route dynamically
The central intersection only allows going straight. The connections for left- and right turns are missing.

Thank you Jakob, 

Re 1:

Could you please advise why the destination is unreachable? I am sure I am missing something here.  Below is the network and neither of 4o and 54i works, but both 1o and 51i work (in changeTarget). What is the reason behind this?

<route id="left" edges="52o 2i 1o 51i" /> this is the route for this vehicle in the rou.xml.

Many thanks
Mohsen

1) This error most likely occurs because the destination edge is not reachable from the current vehicle edge.
2) you can use traci.simulation.findRoute() to get a list of edges as well as the estimated travel time (if a route exists). Alternatively, you can use vehicle.getRoute to get the list of edges after a successful call to changeTarget
3) Autocomplete does not work with the python client because it uses some advanced coding techniques to modify the domain objects. Instead, use the documentation at http://sumo.dlr.de/daily/pydoc/traci.html

Dear SUMO users and developers, 


I would like to change the route dynamically via traci, but I face some challenges and appreciate that if you could assist.

1- by using 
aa=traci.vehicle.getIDList()
traci.vehicle.changeTarget(aa[ 0], "53i")

SUMO throws this error: traci.exceptions. TraCIException: Route replacement failed for left_0
left_0 is the ID of the vehicle.


2- How can I get a list of edges from the current location (by using getRoadID) to the new target "53i" in this case?  

3- I am using visual studio (VS) for connecting to traci and notice that it does not have the autocomplete function, is there a guide about enabling this in VS?


Many thanks
Mohsen
