Hello Jakob,
I was trying to calculate the junction width (as blue lines shown in the
picture), as well as a distance from center-line of each lane to the left side
of the junction edge (as red lines shown in the picture).
Another irrelevant question, I understand that we have a 0.1 meter gap between
the lanes, is there a way that I can remove this gap or specify it to be 0 ?
Thanks,Yifeng

Hello,
currently you can get neither of the points A-F from netedit (besides by
right-clicking on he canvas and chosing 'copy cursor position to the
clipboard').
The .net.xml only contains the shape of the center-line of each lane. You would
have to shift this shape by the width of the lane to compute the outer
boundary. (i.e. using NBEdge::getCWBoundaryLine)
However, if you wish to compute whether vehicles are within lane boundaries
there are other options available.
Maybe you can elaborate on what you need these boundary points for.
regards,
Jakob

Hello All,
I was wondering if I can get all the edge boundary points in the netedit.exe?As
shown in the picture, for both one-way or two-way edge (1->2), can I get the
boundary points A, B, C and D? It is even better if I can get points E and F
for the two-way edge.
I understand that I can get the point A and B in
\src\netbuild\NBNodeShapeComputer::computeNodeShapeDefault() where Position p;
the junction shape points are calculated (when the subject edge is *i (1->2)),
but how about point C, D and E, F?
Any information would be appreciated.
Thank you and cheers.
Zeng
