Simulation of Pedestrian Single-Lane Movement by a Biped Model

Simulation des einspurigen Fußgängerverkehrs durch ein Biped-Modell

The "Biped Model" is developed to simulate pedestrian locomotion by physical step rather than by time step which is usually the case in most known models of pedestrian dynamics. The model consists of two components:

  • the stepping simulator and
  • the adjustment of velocity for each step.

Schematic of the biped model. The stand moment simulator refers to the generation of spatial state at stand moment. The balance moment simulator refers to the generation of a spatial state at the balance moment.

Simulation results show that the velocity-density relations are consistent with the empirical data. Stable stop-and-go waves are simulated with a critical density. Furthermore, with the consideration of biped movement, the lock-step phenomenon is reproduced. The model provides new possibilities to study crowd behavior while considering personal bipedal mechanics. Besides, phenomena like stop-and-go and lock-step could be reproduced fairly well. Also, a good agreement between the experimental and the simulated fundamental diagram was found. For more details we refer to this article.
