crash after rerouting and losing a stop

[Sirius-1110]

Hi !
I have created a bidi road, like

    <edge id="-E22" from="J2" to="J33" priority="-1" spreadType="center" bidi="E22">
        <lane id="-E22_0" index="0" speed="13.89" length="144.30" width="10.00" shape="113.83,107.61 -30.26,99.79"/>
    </edge>
    <edge id="E22" from="J33" to="J2" priority="-1" spreadType="center" bidi="-E22">
        <lane id="E22_0" index="0" disallow="pedestrian" speed="13.89" length="144.30" width="10.00" shape="-30.26,99.79 113.83,107.61"/>
    </edge>

Then I created a loop route, the vehicles depart from E22 and leave on -E22.
When multi-vehicles meet on E22, SUMO crashed without raising any Error.

However, it seems the crash would not happen when there are only 2 vehicles meet on bidi road. Like,

The sumo configuration file is as follows:

<?xml version="1.0" encoding="UTF-8"?>

<!-- generated on 2023-05-04 09:05:01 by Eclipse SUMO sumo Version 1.16.0

<configuration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://sumo.dlr.de/xsd/sumoConfiguration.xsd">

    <input>
        <net-file value="../multi-leg%20intersection/daye.net.xml"/>
        <route-files value="../multi-leg%20intersection/daye_flow.rou.xml"/>
        <additional-files value="../multi-leg%20intersection/daye.add.xml"/>
    </input>
    <processing>
        <lateral-resolution value="0.3"/>
        <collision.action value="warn"/>
        <default.speeddev value="0"/>
        <pedestrian.model value="striping"/>
    </processing>

</configuration>

How can I solve this problem? Thanks.

Probably not the cause of the bidi. In the following scenario, sumo also crashes without throwing an error.

In fact, it is because of some errors when drawing the intersection in Netedit, this error will cause sumo to crash when the vehicle passes through the intersection.

Please provide the input files to make sumo crash because this needs to be fixed.

Sorry, the bug has been fixed before I closed this issue.
I just tried to reproduce this bug, but it didn't work.
I must finish the task of simulation this week, so I'll try to reproduce the bug at a later time (maybe this Sunday).
And my guess is that when I use the "set custom junction shape" of netedit, there are some unreasonable operations.Maybe J24 is too close to J2.

Hello, namdre !
To solve #13192 ,I increased the width of roads E22 and -E22, and changed the lateral-resolution value to 0.1.
The car will still be stuck in the road for a while, but there will be many warning messages

Warning: Vehicle 'flowCrushing14'; frontal collision with vehicle 'flowCrushing11', lane='E3_0', gap=-9.85', latGap=-0.20, time=51.00 stage=move.
Warning: Vehicle 'flowCrushing11'; frontal collision with vehicle 'flowCrushing14', lane='-E3_0', gap=-9.85', latGap=-0.20, time=51.00 stage=move.
Warning: Vehicle 'flowCrushing12'; frontal collision with vehicle 'flowCrushing14', lane='E7_0', gap=-7.83', latGap=-1.80, time=55.00 stage=move.
Warning: Vehicle 'flowCrushing14'; frontal collision with vehicle 'flowCrushing12', lane='-E7_0', gap=-7.83', latGap=-1.80, time=55.00 stage=move.

Then I referd to #9402 and increased the length of all vehicles, the bug occurs again!

when you talking about SUMO crashing, are you referring to the collision warnings are do you mean that the application itself aborts and stops working?

Sorry, I mean that application itself aborts and stops working.
And here are the input files.

"set custom junction shape" of netedit

It is worth mentioning that I didn't use the "set custom junction shape" of netedit this time, so I'm not sure what causes the bug

[namdre]

Thank you for the error example!

By the way: custom junction shapes should rarely be responsible for such problems

note, that your vehicles "lose" their stops on rerouting if the new route doesn't pass the original parkingArea. You could avoid this by defining stops as child elements of the routes which are assigned by the rerouters.

I decided to assign parking areas with traci instead of setting parking areas in the route, and this bug didn't happen again.
Thanks again for your kindness help!
