As two core elements of traffic system, pedestrian and vehicle have always been the focus of research on traffic flow dynamics, and modelling research of them is also one of the important means to explore basic traffic flow, which is helpful to provide scientific guiding principles for the formulation of traffic and crowd evacuation programs under the disaster environment. The theme of the book is to present the basic method of modelling vehicle and pedestrian dynamics on the basis of classical traffic theory and model. The contents mainly include four parts: In the part of vehicle traffic flow modelling, models based on basic car-following and lane-changing behaviour are introduced. In the part of pedestrian traffic flow modelling, pedestrian models that can realistically and accurately reflect characteristics or rules of pedestrian flow are developed. In the part of vehicle-pedestrian mixed traffic flow modelling, an improved KKW model and a pedestrian motion model considering TTC is proposed, in which the spatial motion of a vehicle and a pedestrian is uniformly updated horizontally and longitudinally. In the part of related application, some evacuation models and methods are involved. It is hoped that this book could provide a reference for scholars in the relevant research field. Modelling vehicle and pedestrian movement is of great scientific significance for analyzing and optimizing the evacuation strategies for people in the disaster environment, which also can provide rich and reliable core model library support for the development of traffic software. It is hoped that this book could provide a reference for relevant scholars.
