Serving as an introduction, the book focuses on the microscopic and macroscopic models of traffic flow. It presents the physics and computer science side of traffic research and provides a not-yet-available overview of subject including all aspects and recent developments. The state-of-the-art review on the control of traffic flow, flow in networks, and computer simulation emphasizes the basics and is an essential part of the book. The authors Kai Nagel and Peter Wagner both have backgrounds in physics and computer science and have contributed to all topics covered in the book. Therefore, they offer a new physical perspective on the topic, which addresses the physics and computer science side of traffic research. The combination of modelling and reality in the book manages to narrow the bridge between the different communities significantly.
