do not build vehicle-actuated pedestrian crossings #7637

Closed namdre closed 2 weeks ago

namdre commented 4 years ago

when option --tls.default-type actuated is set (i.e. in the webWizard) even traffic lights for a pedestrian crossing will be vehicle-actuated. This reduces flow in an unrealistic way. Instead, build static tls (or pedestrian-actuated crossing once available #1746)

namdre commented 2 weeks ago

The current remedy (by osmGet.py / osmWebWizard.py) is to set option --tls.discard-simple thereby not building a traffic light for simple crossings at all.

There is still a choice to be made between having a static light (which gives somewhat realistic signal effects even when simulating without pedestrians) or building a pedestrian actuated crossing (#1746). In the later case, vehicle flow is overestimated when the simulation does not model pedestrians because then the light stays green all the time.

Pedestrian crossings are now pedestrian actuated.

making actuated crossings static for non-pedestrian simulations should not be handled at the network level but rather at the simulation level (#15723)
