Re: [sumo-user] Vehicle Position in a Lane
Hello,
if you are looking for examples of lateral evasion, you can look at our sublane model tests at https://github.com/eclipse/sumo/tree/master/tests/sumo/sublane_model
Regarding the files you sent:
- the lateral- resolution parameter was not used in your example
- lateral evasion only takes place if vehicles are driving next to each other for more than a single simulation step.
- in your example, the only car with a modified minGapLat parameter was 'EXT'. However, that car never overtook another vehicle and was always overtaken by much faster cars within a single simulation step

On a somewhat unrelated note: setting accel and decel to 35 for most of the vehicles will likely lead to unrealistic behavior  Values are in m/s^2 and your cars have accelerations/ decelerations that would put most rockets to shame.

regards,
Jakob

Hello, 

I think there was a slight misunderstanding regarding my question. The issue is that in SUMO it does not replicate lateral evasive maneuvers. I changed the "minGapLat" from 0.1 to 2.0, and there was no visual change in the SUMO-gui. Similarly, the lateral-resolution was increased with no visual change. I have attached all the files related to the simulation. Will there be a visual change at all? 

Thanks.

Hello,
- if you just want cars traveling in the center of their lane all the time you can run the default model (not setting the lateral-resolution option)
- if the lanes and vehicles have default width (3.2m and 1.8m-2.4m) then setting --lateral--resolution 0.4 (or lower) should be sufficient to let vehicles pass each other without taking lateral evasive maneuvers (in maneuver planning, the surrounding vehicles widths are rounded up to occupy full sublanes thus exaggerating their width depending on resolution)
- you can lower the vType parameter 'minGapLat' from its default of 0.6m to reduce evasive behavior

Jakob

Hello, 

I have noticed the trend that passing vehicles stay towards the far edge of a lane when passing a car or truck. I have tried changing some of the variables within the sublane model, to increase the lateral spacing, but it has been without luck. I have also tried changing the "--lateral-resolution", but it did not work. Do I have to enable the sublane model somehow within the simulation? I am wondering what the best way to incorporate this idea will be. 

Thanks

(The scenario trying to be modeled can be seen in the attached image. This is data from our driving simulator that is not yet replicated on SUMO)
