Introduction

The understanding of vehicular movement has been a long-standing focal point in traffic flow theory. The modeling of such movement methodologies not only finds direct application in traffic analysis, but also holds substantial potential within the AVs industry, particularly as CAVs progressively infuse the system. This section firstly briefly describes the basics of microscopic traffic flow modeling concept, and then discuss the challenges brought by the autonomous vehicles. After that, literature review is conducted for car following and lane changing behaviors, which are major two models of microscopic traffic flow models. The drawbacks of current models are presented, together with the structure of the book.
