collision between bike and ped on shared path at TLS-intersection #11641

Open yunpangfloetteroed opened 2 years ago

Add your issue description here. (1) as title; The reason is that the pedestrian keeps approaching the bike for reaching the crosswalk although there is no enough space.

(2) bikes and the pedestrian keep staying even during the green phase. It results in teleporting of all three objects. It seems that the pedestrian block the way.

The pedestrian tries to squeeze himself for passing one bike (on the rightmost side) in front of the intersection. At this moment, the pre-defined jamming time (300 s) is not reached. So, it should not be a jamming behaviour. or?

Being completely blocked by vehicles triggers instant jammed mode

The bike does not consider the existance of the pedestrian and changes his position from the leftmost to the rightmost side right in front of the stop line, and block the pedestrian's way. it is also not expected.

this is due to #7026 (triggers the initial pedestrian jamming)

The signal timing plan in the attached example/test is adjusted. Bikes has minor green and the ped has major green. Bikes accelerate on the crosswalk and can pass the pedestrian, but then make emergency braking at the end of the crosswalk. Why? It is expected that they should be able to avoid emergency braking.

The bikes do not "see" the crossing pedestrians while they are driving across a pedestrian crossing lengthwise. This is a bug. Currently, pedestrians are only noticed when a) passing a crossing crosswise b) the person is on a "shared" walkingarea
