Re: [sumo-user] Vehicle stops following the route after calling moveToXY()
It may help to make the Geforce the default adapter. On my system, sumo-gui was using  the integrated graphics adapter by default and this had a huge impact on running time. (open the nvidia system control panel (should be available from a right click on the desktop background) go to 3D settings and select nvidia as your preferred graphics processor).
There is still a known issue where 'show-route' drops the gui refresh rate while the simulation is running but at least you should have no problem seeing routes in a stopped simulation.

That was it indeed, thanks very much for the fast response!
I did try visualizing the route in sumo-gui, but that dropped framerate to under 1 per second (in netedit the route is shown with decent framerate, and I have an nVidia Geforce RTX2080). I could see it was on the route though, it just didn't want to move.

Most likely, the last call to setSpeed is keeping the vehicle from moving. To hand speed control back to SUMO, call setSpeed(vehID, -1).
You can check whether the route was set correctly in sumo-gui: https://sumo.dlr.de/docs/sumo-gui.html#showing_routes_and_route-related_information

Hi,

I'm creating an application where I can either control a SUMO car from my program, or let SUMO drive autonomously over a route.
When my program is in control I call Vehicle::moveToXY() and Vehicle::setSpeed() to overrule the position. This works ok. But when I try to hand control back to SUMO (not calling moveToXY/setSpeed anymore) it just sits there without moving.

My vehicle is define in the .rou.xml file like this:

<vehicle id="ego" type="Ego_Car" route="r_1" depart="0.00" departLane="free" color="blue"/>

I tried explicitly setting the route ID:

Vehicle::setRouteID(egoName, routeID);

but that didn't help. Any idea how I can detect what is causing the vehicle not to follow the route anymore? Is it even possible after a call to Vehicle::moveToXY() to put the vehicle back on a route, or should I respawn the vehicle somehow from scratch? (even then I'd need to inject the latest position at least once)

Thanks,
Ruud van Gaal
