Modeling Pedestrian Detour Behavior By-Passing Conflict Areas

In the process of walking, most pedestrians prefer to choose shortest path, which requires passing through conflict area. However, in case high crowd density, 5–20% total population will follow pre-planned route before walking or during initial period trip bypass Aiming at reproducing this detour behavior phenomenon, an extended social force model (SFM) is proposed according a three-layer pedestrian simulation framework. This not only fully considers choice mode, but also contains avoidance and game point. At strategic layer, mode selection based on Logit established considering starting time angle, distinguish between two groups who those repeatedly adjust trip. Then, path decision visual perception density tactical layer Voronoi-based SFM operational are combined guide specific movement types groups. A series evaluation indexes such as central mean local level selected, Kolmogorov–Smirnov (K-S) test dynamic warping (DTW) method used evaluate compare scores each index different models. The results show that can improve existing certain extent. sum, travel score, level, score respectively increase from 0.71 0.81, 0.46 0.39 0.48, indicates significant improvement performance.
