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

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Until this ticket is fixed, the only remedy is to reduce lateral resolution:

- the car-following module treats surrounding vehicles as if they occupy their sublanes fully

- if the vehicle width is not a multiple of the lateral resolution, this introduces a virtual buffer around the vehicle. In the extreme case of lateral-resolution = laneWidth, each vehicle is assured to use it's lane exclusively (yet lateral movements will be smooth).

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 this
situation. Also, the other issue is the min lateral gap is not considered
when a vehicle passes a stopped vehicle. This happens when some vehicles are
ordered by TraCI changeLane command to move to right lane and some vehicle
have already stopped in the right side of the right lane. They pass stopped
vehicles approximately with no lateral gap.
