Hi Don,
there is a dedicated command to let vehicles stop explicitly:
traci.vehicle.setStop
<https://sumo.dlr.de/pydoc/traci._vehicle.html#VehicleDomain-setStop> . If
you use that one, vehicles will overtake the stopping vehicle. Although I
admit your approach should not break the overtaking feature and needs
further investigation from our side.
Best regards
Mirko

Betreff: [sumo-user] Opposite side overtaking stopped vehicles

Hi,
I am currently working on a traffic simulation project using SUMO and
TraCI, and I have encountered an issue that I hope you can assist me with.
In my simulation, I want to model a scenario where a specific vehicle (with
type "ego") stops on a two-way road with one lane per direction of travel,
and the following vehicles overtake it by using the opposite lane. I have
tried to implement this behaviour using the traci.vehicle.slowDown and
traci.vehicle.setSpeed commands, but the following vehicles do not overtake
the stopped vehicle as desired.
I have attached the TraCI script and the corresponding .net, .rou, and
.sumocfg files for your reference.
Here is a brief summary of what I have tried:
Using traci.vehicle.slowDown to gradually slow down the vehicle to a stop.
Using traci.vehicle.setSpeed to set the speed of the vehicle to zero.
In both cases, the target vehicle stops as expected, but the following
vehicles do not overtake it. I have ensured that the road allows overtaking
in the opposite lane and have experimented with various lane-changing
parameters and models, but the issue persists.
Is there a specific configuration or approach that would allow the
following vehicles to overtake a stopped vehicle? I need to do this to
study the operational impact of vehicles breaking down on such roads.
Thank you in advance for your assistance. I look forward to hearing from
you.
Best
Don
