Re: [sumo-user] Set checkpoint lanes in a highway for a veh flow in Ecli

[Kostas Beis <kostasbeis97@xxxxxxxxx>]

Hi Mirko,

thanks for your quick response

creating bottlenecks will create a traffic jam in my scenario

I'm trying to avoid me setting the changelane in TraCI because i want to test how sumo default reacts to checkpoint setting in comparison with a experimental strategy of mine

I added to the route file in the desired flow the " viaXY="6500.00,0.60" " which are the coordinates of the desired checkpoint but it doesnt seem to work

I read that I need to set the --mapmatch.junctions option but I don't know how to include it in the simulation configuration file

I see two options here:

• If you don't mind creating bottlenecks at your checkpoints, then create them "physically", thus split the highway of five lanes into three edges of one to two lanes for a very short stretch (can be 1m). Then you can create routes through specific checkpoints as you like.
• Issue lane change commands via TraCI (see https://sumo.dlr.de/docs/TraCI.html, https://sumo.dlr.de/pydoc/traci._vehicle.html#VehicleDomain-changeLane)

Best regards

My simulation consists of a 5-lane, 10 km long highway with different vehicle flows. I want one veh flow to pass through 2nd lane at 3 km, through 4th lane at 6 km and to arrive at 3rd lane at 10 km. Some kind of "checkpoints" inside the highway. I have managed to set only the arrival target lane (3rd) in the route file of simulation by writing arrivalLane="4" in specs of the flow. Can anyone help?
