Prolonged clogs in bottleneck simulations for pedestrian dynamics

This article studies clogging phenomena using a velocity-based model for pedestrian dynamics. First, method to identify prolonged clogs in simulations was introduced. Then bottleneck were implemented with different initial and boundary conditions. The number of analyzed investigate the decisive factors causing this phenomenon. Moreover, time lapse between two consecutive agents passing exit, trajectories analyzed. influence three type studied: parameters spatial boundaries, algorithmic related implementation model, movement model. Parameters boundaries include width position exit. Algorithmic are update methods size step. Model cover several describing level motivation, strength range impact among agents, shape agents. results show that occurrence is closely linked but has virtually no correlation factors.
