Sumo-Option WalkingArea intermediate points

[Domsall]

When loading a SUMO configuration/simulation WalkingAreas get a predefined number of intermediate points.

It would be great to have an option similar to netconverts --junctions.internal-link-detail to smooth out WalkingLanes within the intersection. With the current implementation, the angle difference between the start/ending of WalkingLanes and Edges can be extremly high.

The responsible code is in https://github.com/eclipse/sumo/blob/35c5ed5661c1f5fe417e0a997efaee03d23d652a/src/microsim/transportables/MSPModel_Striping.cpp#L320

After testing different implementations, I recognized that adding a few lines of Code like the following should solve the problem:

const OptionsCont& oc = OptionsCont::getOptions();
const int numPoints = oc.getInt("junctions.internal-link-detail");
shape = shape.bezier(numPoints);

Am I missing something?! Do you have any suggestions for the naming?!

since the shapes are specific to the striping model, I would name the option --pedestrian.striping.walkingarea-detail

The current implementation has shapes with either 4 or 2 points. The bezier function should only be applied to the 4-point shapes but should then lead to reasonably smooth shapes in most cases.
The shapes will become longer though and I'm not sure whether that will increase realism.
But since it's optional, I see no problem with this.
