Simulation of a Signalised Pedestrian Crossing

VISWALK is PTV Vision's pedestrian simulation (also called crowd simulation) software. It is fully integrated into VISSIM, PTV Vision's renowned and market-leading traffic simulation software.

In this way VISSIM offers several ways to model pedestrian-vehicle-interaction. It offers a wide range to customize these interactions to meet the local behavior.

This demonstration example of a VISSIM simulation shows pedestrians crossing a street at a signalized, pedestrian actuated crossing. For better illustration, the state of the signals is additionally visualized with colored and protruding stop lines after about 15 seconds. At the same time the color of the pedestrians changes from normal to a color that depicts their behavior:

The green pedestrians always obey the traffic light: They operate the signal (push the button) and wait for the green light to come in order to cross.

The yellow pedestrians also push the button, but when there is a sufficient gap between the vehicles on the street, they do not obey the red light and immediately start to cross.

The red pedestrians do not push the button and ignore the red light by simply crossing whenever road traffic allows them to. They just behave as if there was no signalization at all.

An entirely free 30 days trial version with full simulation capability is available at www.ptv-vision.com/demo .

I know it's only an example, but, is it possible consideer elderly people, handicape people, women with baby, etc? They walk slow, and, as Bartolomiej, the time is too short to for this crossing. If it's difficult to people without problems fot walk, imagine so for those people above!

@carolinamlopes: yes, it is possible to change the walking speed of people (0 to 20 km/h), cars, and of course all timings of the traffic signal program can be freely set.

what program is this?

[ptvvision]

@duillana: this is VISSIM. See more visualizations of traffic simulations in our channel.

@catsrsuper In Soviet Russia, you always find a proper saying for nonsense. ;-)

@cyclenut There is a difference between KNOWING the laws (which I do) and following the laws (which I may or may not do). For instance most states say you must be stopped until the person has fully crossed a cross walk. Meaning even though they are now in the other lane, you have to wait for them to keep going (which makes sense incase they decide to be idiots and do an about face and start running the other direction).

That being said, I'd rather just hit them than wait ;)

@cyclenut in Britan, wait for the best chance.

In the US, we are to stop and let any person already on the road cross. Being trapped in the middle of the road is very dangerous and should not be allowed.

In some states vehicles have to stop for people on the edge wanting to cross. A few states say a person crossing mid-block without a crosswalk have right-a-way.

Let me point out, I'm one of very few Americans that read traffic laws...

if you want to make chaos complete, you need to implement cars overtaking on the crossing (just as passing pedestrians over red).

BTW: Why are there are no pedestrians coming back?
