[sumo-user] Question

Hi all, I intend to perform simulation in sub-lane model. I was wondering to know whether there is a way to make vehicles drive in specific sub-lanes. For instance, making a vehicle to drive in rightmost sub-lanes. Thanks, Reza. ___ sumo-user mailing

[sumo-user] Lane change state

Hi, I was wondering to get the state of a vehicle with TraCI commands to see whether the vehicle is in the middle of lane changing or not. I used "getLaneChangeState" command. However, I did not understand the results of this command. Based on the link

Re: [sumo-user] Problem with laneChange command in TraCI

Thank you very much dear Jakob for your detailed answers. I did all your solutions but did not get what I needed. The main problem is that min lat gap is not observed. I set min lat gap to 1.8, but I still see that vehicles come closer than this limit to each other. I was wondering to know whether

[sumo-user] Cooperative lane-changing

Hi, I would like to know more about the details of cooperative lane-changing. I read the article about lane-changing by Jakob (Erdmann, J., 2015. SUMO’s lane-changing model. In Modeling Mobility with Open Data (pp. 105-123). Springer, Cham.). However, it did not give details about cooperative

Re: [sumo-user] Problem with laneChange command in TraCI

The same thing happened in my simulation, and vehicles did not brake to prevent it. The width of a passenger car is 1.8 m, and the minGapLat was set to 1.5 m. Therefore, when three vehicles move side by side in two lanes, the min lateral gap was not observed. Please find attached a screenshot of

[sumo-user] Vertical movement of vehicles

Hi, I have encountered some situations in the simulation in which vehicles move vertically to change lane. This happens mostly in congested areas. I was wondering to know how I can prevent it. Please find attached a recorded video of this behavior. Regards, Reza. ezyzip_(3).zip

[sumo-user] Creating on-ramp

Hi, I intend to make a connection between a three-lane road segment to a two-lane segment in order to create the merging point of a highway on-ramp. However, the third lane of the first segment cannot make a connection to the second segment. I was wondering to know how I can make this connection.

Re: [sumo-user] Cooperative lane-changing

I was wondering to know how I can adjust the cooperative lane changing or create another cooperative lane-changing and speed adjustment to react to failed TraCI lane change commands. I would like to know how I can find the codes behind SUMO's cooperative lane-changing and speed adjustments.

[sumo-user] Problem in Set Lateral Alignment in TraCI

Hi, I wrote a code, in TraCI, in order to make vehicles to pull over and stop in a two-lane one-way road and in a specified duration. For the vehicles moving in the right lane, the lateral alignment is set to "right," and the speed is set to 0. Also vehicles in the left lane are forced to change

In order to make my modeling more close to reality I need to use the sublane model. However, I was wondering to know if there is any way to force two vehicles not to occupy the same lane in the same distance from the origin. In this way, when a vehicle intends to change its lane, it does not
