Re: [sumo-user] Teleporting Vehicle
- badly coordinated traffic lights when there are multiple lights close to each other. A good solution is to define a joint controller with a custom signal plan: https://sumo.dlr.de/docs/Simulation/Traffic_Lights.html#controlling_multiple_junctions_with_the_same_controller
- traffic that doesn't adapt their routes in response to jamming (can happen if you are loading vehicles with fixed routes, should work fine if you are loading trips
- too much traffic

Thanks! Increasing the priority of the edges that are part of the roundabout helped a lot.

I also noticed that in my simulation, in places on the network with traffic lights, there is a conflict and the vehicles are not moving. As in the image below:
What can is happening?

The bicyle path that passes across the roundabout has prevented netconvert from recognizing the roundabout as such. Instead of giving priority to vehicles inside the roundabout, priority was given to the entering vehicles. This swiftly causes deadlock. A quick remedy with netedit would be to select all edges that are part of the roundabout and increase their priority to '15' (higher than the surrounding edges). This will fix right-of-way and should solve your deadlocks.

Thanks for the answer Jakob.
The network was imported from OpenStreetMap, so I don't know if I should make some adjustments to improve the network and its connections. The roundabouts are just like the image below. There are other conflicts that I have observed on the network, but I believe most are at the roundabouts.



Please if you can look at my data and give me recommendations mainly regarding the network.

Thanks

There are no studies for teleportation limits that I'm aware of. Our own rule of thumb is to tolerate teleports in large simulations if its under 0.1% of total traffic.
If you get deadlock in roundabouts it might be due to mis-modelled right-of-way, bad connections or because there are traffic lights with unsuitable signal plans involved.

Hello,

I am simulating morning rush hour congestion. But it is having a lot of conflicts at various roundabouts, and the vehicles no longer move in the simulation.
Would the solution be only if teleportation is allowed? (I had left <time-to-teleport value="-1"/>, but I fixed this problem in the simulation)
And do you have any recommendations to improve congested networks?
Does anyone know if there is a document, tutorial or published article that limits the number of vehicles (or percentage of vehicles) teleported so that we can still trust the output data? Because there are many warnings of teleported vehicles in my simulation, and I would like to see studies for teleportation limits.

Thanks.
