Abstract

The presented paper compares the impact of different assumptions and limitations on variables in physics based pedestrian models. It questions commonly made assumptions on their validity, impact and significance and compares them to data from other works, such as meta studies about real world behavior of pedestrians. The paper features a testbed utilizing a cellular automata powered algorithm within a multi layer model to simulate different constraints and strategies, for example assuming a fixed maximum velocity of pedestrians, likelihood distributions of pedestrians' velocity, ego vehicle velocities and pedestrian density. These results are interpreted in their different effects on the outcome, which are evaluated against commonly agreed safety requirements. Eventually, key take-aways for sound claims on safe predictions models are extracted.
