Program running error with 'sumogym_tester.py' about naturalistic-sumo-gym HOT 4 CLOSED

Hi,

1. The first issue is related to the speed limit of a lane and the speed of a vehicle. SUMO gives these warnings(errors) because the speed of a vehicle exceeds the speed limit of the lane it is assigned to. Setting random speed could be a quick fix. You can also try to increase the speed limit of lanes in the network.

2. I was not able to reproduce this error. Could you share more information about it? Did it happen in the beginning of the experiment or after several iterations? Also, some code snippets or screenshots could be helpful.

Thanks.

Hi,
Thank you for your patient answer.Regarding the second question, I'd like to provide the following screenshots.

As you can see, I gave an ID, but it seems that the program is running to

Curr _ pos = traci.vehicle.getposition (self.egoid) (probably on line 143)

Previously, only a few cars were loaded into the map, so the ID of the car could not be captured, resulting in LaneID being'', entering the if loop, returning the value of None, obs being NoneType, and an error occurred.

Could you please offer some suggestions? Thank you for your answer.

Hi,

Thanks for providing the information. I believe this is an out-of-network issue that happened to the ego vehicle. We have a checkpoint from Lines 450-482 in sumo_gym.py:

# sim check before traci update
if in_road == False or lane_id == "":
    info["debug"] = "Ego-vehicle is out of network"
    sim_check = True
elif self.egoID in traci.simulation.getCollidingVehiclesIDList():
    info["debug"] = "A crash happened to the Ego-vehicle"
    sim_check = True
else:
   .......

This captures the out-of-network issue and shuts down the program. So it takes care of the None observation issue as well.

I noticed that this error happened in the reset stage in your example? Did it happen at the beginning of the simulation then? Also, did you make any changes to the original code?

Thanks.

Hi Shen, it seems for some reason, your code is starting with the ego-vehicle being out of network, which suggests some problem with either the road network or the ego vehicle initialization. You can check the net and route files but I dont think its a problem with the code. I am closing this issue but if you still keep on having problems, you can reopen it again.
