Re: [sumo-user] Novel one-lane road for both directions, and any workaro

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

right now, full bidirectional operation is only possible with trains.

You have two methods to emulate the desired behavior for cars:

1) by using opposite direction driving (https://sumo.dlr.de/docs/Simulation/OppositeDirectionDriving.html)

  - place lots of standing cars as obstacles on the road. Vehicles will be forced on the opposite side to pass the obstacles.

  - areas without obstacles are the detour locations.

2)

- place two edges going in opposite direction directly on top of each other (i.e. by setting attribute spreadType="center" and giving them the reversed geometry).

- use TraCI to detect dangerous situations

- call vehicle.setStop(...,flags=traci.constants.STOP_PARKING) to clear the road for oncoming traffic and avoid a collision

regards,

Jakob

Hello all,

I have a novel situation that I need to model and I would like to know if it is technically possible in SUMO:

I must model a one lane road which operates in both directions, i.e. the road does not have a lane in each direction, it is literally one lane used by vehicles going in opposite directions, obviously towards each other.

(Just for context, the idea is to make the oncoming vehicles somehow (perhaps using TraCI or something) avoid colliding into each other by detecting each other from a distance and then one of them rerouting into a small pit-stop or shoulder or D-tour until it safe to get back on the road and continue moving forward.)

Is it even technically possible to code such a road in SUMO?

Thank you,

Kadri
