Abstract
Based on traffic information, an extended two-dimensional optimal velocity model is presented by incorporating velocity difference between two neighboring pedestrians. Linear stability conditions are obtained by theoretical analysis, and the results show that the traffic information can promote the stability of pedestrian flow. Furthermore, the model is applied to mixed pedestrian flow, where only part of pedestrians follows the information and others neglect it. It is found that the pedestrians complying with traffic guidance system (called TGS pedestrian) can make the mixed flow more stable, and some unstable regions can change to stable region when the proportion of TGS pedestrian is large enough. It is also found that the initial distribution of them has little effect on the flow.
