Hello,
the problem is this: https://github.com/eclipse/sumo/issues/8482
Make sure that all the 'state' definitions have the correct length.

Hi,

it seems that the sumo-gui process exits with exit code 1,  no core.

It can be reproduced also with a current version (ok 4 days old)

Re: [sumo-user] About the state of the simulation when multiple parking areas are created

[g2121044]

I understand.
I will try to figure out the cause again based on the two advices you gave me.


Thank you for the information very much,

- if for some reason the number of traci calls is increased, this can have an 
impact on running speed. You could test this be using libsumo which removes 
this communication overhead (https://sumo.dlr.de/docs/Libsumo.html)
- it would be helpful if you could figure out whether the additional running 
time is spent in sumo or in your own script. Currently, the only way to do this 
is to log the duration of the traci.simulationStep calls from within your script

Yes, I am controlling the vehicle with TraCI.
- Are you using a cab device? If so, how are you doing it?
No, I am not using a cab.
- Are you using Rerouter with parkingAreaReroute?
No, I am not using rerouter.


The simple flow of the simulation is as follows.
1. Move each vehicle to the parking area as soon as the simulation starts. 2. 
(This process is only in rou.xml)
2. When a customer request is received, the dispatching algorithm and the 
duarouter determine the route and vehicle. 
3. The route is changed to the target vehicle using traci.vehicle.setRoute.
4. When the vehicle arrives at the boarding and alighting point, if all the 
assigned requests have been fulfilled, the vehicle will change target to the 
parking area.


From the state 1 of this flow, the process is slowing down.
And when I compared the speed of the simulation by changing only the number of 
parking areas, the difference in speed was noticeable. (All other conditions 
were the same except for the parking area.)
Therefore, I thought that the parking area was the cause.
However, when I found out that it was not the cause, the problem became even 
more difficult.

Hello,
ParkingAreas by themselves should have no impact on simulation speed.

- are you controlling the vehicles via TraCI?
- are you using the taxi device? If so, how?
- are you using rerouters with parkingAreaReroute?

Hello Everyone

I have a question about the state of the simulation when multiple parking areas 
are created.

I am a graduate student and I am using SUMO for my research on DARP (dial a 
ride problem).
I set up four parking areas on the four sides of a square road network, and 
simulated DAR on the road network.
The number of vehicles is set to 8. Each of the four parking areas has two 
vehicles waiting for a customer's request.

As a result of the simulation, the processing speed of the simulation was 
clearly reduced compared to the case with one parking area. The speed of the 
simulation was probably reduced by more than 90%.

Does the simulation process become slower when multiple parking areas are 
created?

I have tried to use multi-threading (--device.router.thread), but it does not 
work.

Kazuma Nishikawa

Re: [sumo-user] Issue with new Netedit version

[Jakob Erdmann]

Hello,
I suppose there must be something special about your use-case because
'move' mode does work as expected in our tests.
These things might help (not necessarily all at once):

- try the latest development version:
https://sumo.dlr.de/docs/Downloads.php#sumo_-_latest_development_version
(this will be released as 1.9.0 soon anyway)
- provide the network file and describe in details where you tried to click
- provide a screencast of the problem
