Traffic Flow Theory: Characteristics, Experimental Methods, and Numerical Techniques provide traffic engineers with the necessary methods and techniques for mathematically representing traffic flow. The book begins with a rigorous but easy to understand exposition of traffic flow characteristics including Intelligent Transportation Systems (ITS) and traffic sensing technologies.
- Includes worked out examples and cases to illustrate concepts, models, and theories
- Provides modeling and analytical procedures for supporting different aspects of traffic analyses for supporting different flow models
- Carefully explains the dynamics of traffic flow over time and space
