[sumo-user] TraCI run rerouter got warning "no connection" and cause eme

[Todd Chang <cchiahs1@xxxxxxx>]

Hi All,

 

I have problems when I try 2 methods to repeat vehicle route.

 

1.

I set up a rerouter to let vehicle run in repeated circle.

I use TraCI to run SUMO because I want to store vehicle speed.

 

The simulation goes well and the vehicles are cycling without problem.

But at some time point, the warning message appears:

“Warning: Vehicle ‘1’ performs emergency stop at the end of lane ‘e2_0’ because there is no connection to the next edge.”

Edge ‘e2’ is where I set rerouter.

This is weird because of course the edges are connected.

So the vehicle speed will jump to 0 and then jump to a unrealistic high value.

I was wondering how to solve this.

 

2.

I also tried the repeat commend in route setting instead of rerouter.

The vehicle repeats the route when I run sumo-gui.

But the vehicle won’t repeat when I use TraCI to run the simulation, it just run the route once and disappear.

How can I repeat the routes when run with TraCI?

 

Thanks.
