Hi i'm using OpenPlanner 2.0 clone at hatem gitalb.

I want insert the information about dotted line for lane change possibility

so i revise lane.csv all LaneChgFG to 0 (openplanner enableLaneChange flag true)

vehicle still do lanechange.

there is a way for this problem?

for solve this problem, i think FindAdjacentLanesV2 function may be change to check LaneChgFG information

is it right?

Hi @ichthus_han,

Sorry this flag is not supported.

It should be easy fix I will add it to my change list.

Currently the lane change happen as the following.

1- FindAdjacentLanesV2 is called when the map is loaded.

2- FindAdjacentLanesV2 search for any parallel lanes and for each waypoint it assign left and right waypoints.

3- Left and Right Ids information is used in the lane change planning.

But the problem with "LaneChgFG" it doesn't give information about the left and right lanes. that is why I don't use it.

you can create a feature request or issue on my GitLab fork so I can follow up.

@Hatem AdjacentLanesV2 function find parallel lane just regard the area boundary(3.5 m default) right? if is right, i think find adjacent lane with lanchangeFG is possible So, left or right lane will find when find the parallel lane boundary is smaller than 3.5m and LaneChangeFG true. is it possible idea?

Sure , that is possible. It is similar to what I added to my change list. how soon do you need this feature ? also can you share a map so I can test it with.
