I will leave the car-pedestrian interaction as is for the moment. It would be interesting to see if AnyLogic plans to change this in the future. So the current situation leaves us with two very capable libraries that are best used for their intended areas: pedestrian movements and car traffic, where both do not come into contact with the other too much. Cars should do emergency stops, look around corners upon turning and dynamically adjust their view areas. Pedestrians should start “watching” their surroundings for cars as well. However, to approach realistic interactions, you’d need much more advanced screening heuristics. So cars and pedestrians do not know each other too well. What are your ideas to improve the situation? Verdict This is possible but beyond the scope of this little exploration. This is where you would need to start creating much more intelligent heuristics beyond my simplistic “stop if someone is in the view area”. This is what it looks like:Īs you can see, cars do stop as soon as they observe pedestrians. As soon as the car “sees” a pedestrian, it goes into state “stopForPed”, waits for 10 seconds and then resumes its normal driving. Notice how we need to to transform XY coordinates to align pedestrians and cars. Adjust it such that pedestrians only leave it “on free() function call” as below: The first step is to add a “PedWait” object one pedestrians reach the crossroads. This way, they can cross the road without crashing orthogonal traffic. We will make them wait at the traffic light until their parallel traffic gets green lights. Now the pedestrian library has some blocks that we can employ to mimic pedestrians adhering to traffic. Last time, we already added a traffic light system to our cross roads. There are two workarounds for you: simple and complex. While this might be sensible from a modelling perspective, it is clearly a drawback for a large portion of traffic models that look at the interaction of cars and pedestrians. Each is aware of their own world and there is little overlap.
They are not even crashing into each other.Ĭurrently, car and pedestrian agents do live in separate “worlds”, so to speak. And if you just closed your eyes to avoid seeing horrible pedestrian scenes, there is no need: cars simply pass through pedestrians like ghosts would. Pedestrians will walk across the road (of which they have no perception, actually) without “seeing” cars approaching.Īt the same time, cars do not “see” pedestrians so they happily drive on even if a flock of pedestrians blocks their way. While AnyLogic generally aims for a “everything works with everything else” philosophy, this is one example where it doesn’t hold. Now, you might be hoping that pedestrians look out for car agents while trying to cross the road.
