Abstract: Freeway traffic management is a business process,which helps to maximize the productivity of freeway.Its core task is to balance the demand and capacity,prevent traffic congestion,and minimize traffic accidents.Based on a comprehensive review of the theories and practices in the traffic management of modern freeway,it is concluded that a successful freeway traffic management program has to incorporate the following three core concepts,i.e. (1) the concept of information-driven and performance-based management; (2) the concept of system management;and (3) the concept of proactive system management.Information-driven and performance-based management serves as the basis of such a successful program,while system management as the primary strategies,and the proactive management as the ultimate goal.These three concepts constitute the key concepts of modern freeway management.As a necessary prerequisite to manage freeway well,these three key concepts provide the fundamental guidance to the manager,who will propose the feasible management strategies fitting with the practical situation.It is hoped that discussions of these key concepts will help to enhance freeway management practice,improve freeway operation efficiency and freeway traffic safety.
