Re: [sumo-user] Grid Deadlock
Thanks Jakob

Using the latest development version of netgenerate, you can create splits with options --turn-lanes 1 and --turn-lanes.length 50
This has the side effect of creating an additional turn lane but that could actually improve your scenario if you reduce the default.lanenumber correspondingly.

I see, so thats made manually with netedit? 
Is it possible to generate it like that from netgenerate ?

Best regards,

You cannot. The rerouter always applies to the whole edge. You can only split the edge into two seperate edges and place the rerouter on the first one.

Hi Jakob,

How can I give the rerouter the position where I want to place it in the edge?

Best regards,
José

Hello,
The time-to-teleport should not be lower than the longest traffic light cycle as this is an expected waiting time. The default value of 300 for teleporting serves this purpose.

The deadlock is caused by https://github.com/eclipse/sumo/issues/4257
A remedy would be to split the rerouter edge along its length and put the rerouter on the first part so that vehicles are not rerouted close to the intersection.
The symptoms of the deadlock (opposing strategic lane change request by parallel vehicles) was not easily visible due to https://github.com/eclipse/sumo/issues/4258 (now fixed).

Jakob

I enabled teleporting and got the following for a small amount of vehicles (10) 

Warning: Teleporting vehicle 'flow0.3'; waited too long (wrong lane), lane='C1toB1_2', time=3091.00.
Warning: Vehicle 'flow0.3' ends teleporting on edge 'B1toB0', time 3091.00.

What should be a good number for teleporting? I had set it on 1000. And in 1 or 10 is teleporting everything.

Best regards,
José

I have ran the simulation a few times, and its the same 2 vehicles that stop there flow0.7 and flow0.9 from a total of 100 vehicles(before 20).

Jakob,

This is another execution and there are four at the moment in deadlock,

If the deadlock consists only of the vehicles show in the first screenshot, please paste another screenshot that shows a closeup of the vehicles in front of the intersection.

I added that to my flow, but I get the same error.

This is my rou.xml definition


<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://sumo.dlr.de/xsd/routes_file.xsd">
  <!-- Vehicles Types -->
  <vType color="211,242,0" guiShape="passenger/wagon" id="schumacher" maxSpeed="22.22" speedFactor="normc(1,0.1,0.2,2)" vClass="private" />

  <!-- flows -->
  <flow id="flow0" begin="0" number="20" type="schumacher" from="B0toB1" to="C1toB1" via="C2toC1" departLane="best"/>
</routes>

and my additional file

<additionals>
    <rerouter id="rerouter0" edges="B1toB2">
        <interval end="1e9">
            <destProbReroute id="C1toB1" />
            <destProbReroute id="A2toA3" />
        </interval>
    </rerouter>
    <rerouter id="rerouter1" edges="C1toB1">
        <interval end="1e9">
            <destProbReroute id="B1toB2" />
            <destProbReroute id="B0toC0" />
        </interval>
    </rerouter>
    <rerouter id="rerouter0" edges="A2toA3">
        <interval end="1e9">
            <destProbReroute id="B1toB2" />
        </interval>
    </rerouter>
    <rerouter id="rerouter1" edges="B0toC0">
        <interval end="1e9">
            <destProbReroute id="B1toB2" />
        </interval>
    </rerouter>
</additionals>
Its a grid of 4 by 4.

After a few seconds the deadlock starts.
Is there any improvement I could do to my configurations?
I am adding 100 vehicles to the network from time 0 to 6000.

Best regards,
Jose

Hey everyone,

Has anyone experienced Deadlocks in their simulations?
I have been trying to figure out why is this happening without luck.

Here is a Screenshot,

If anyone has any hint, I will thank you.

Best regards,
José
