Pedestrians’ violation behavior model based on group decision-making

Based on dynamic group decision theory of herd mentality, this study analyzed pedestrian violation mechanism and focused on the interaction views of pedestrian violation under the influence of herd mentality. For a typical signalized intersection in Yangzhou of China, a dynamic group decision-making model of pedestrians’ illegal crossing is established with opinion dynamics theory and scale-free network. Opinion leaders were considered and introduced in this model to capture the limitations of individual homogenization. Then, MATLAB was used to simulate and present the dynamic evolution process of decision makers. Results suggested that under the general conditions, the group decision results are closely related to the initial degree of knowledge, and once a few people lead the violation, there would be a greater probability of an illegal group crossing in the intersection. More importantly, the results gave a clear dynamic evolution process of the viewpoint and provided reference for similar research and a good guide for the management of violation crossing.
