| Re: [sumo-user] modelling pedestrians correctly |
_______________________________________________Dear all,
currently, when modelling pedestrians, I always use 'regular' edges and connections. This results in warnings (such as "Warning: Vehicle type '7' with vClass=pedestrian should only be used for persons and not for vehicle 'ped26'."), and sometimes pedestrians accidentally end up on the street (which I can solve by disallowing them). I do nonetheless because: it allows usage of E2 type detectors to detect presence of pedestrian-style vehicles, and it is easy to build the network cause I can just use regular connections. Pedestrians will stand in line at the intersection, but I am mostly interested in the general flow of traffic, and there are generally few pedestrians in the simulation.
However, it would be nice to model the pedestrians more correctly. I wonder, given an intersection like this:
How can I build the network so that the pedestrians will only cross from the sidewalk edges on the one side to the sidewalk edges on the other side, and have a detector (button) on either side of the crossing? Beause of the way my TraCI application works, most preferably this would be an E2 detector.
Should I create sidewalk-edges only in a single direction, since pedestrians can walk in two directions? If so, how to avoid pedestrians that just crossed the intersection from activating the detection?
Actually all traffic has detectors, that I did add draw in the above simplified example. A typical intersection may look more like this:
And in the simulation like this (note a lot of traffic lights are light blue, and thus actually not controlled):
any help is appreciated!
