Nowadays, due to increased traffic congestion in roadway networks and limited resources, integrated corridor system management is becoming essential to traffic managers. This paper presents a case study of State Route 4 (SR 4) in California to demonstrate the practice of integrated corridor system management. In order to better manage the corridor system, the authors answer these questions: 1) what are the current and future problems of the corridor, 2) where are the existing and future congestion areas, 3) where are the existing and future bottleneck locations, 4) what are the causes of the congestion, 5) what are possible improvement strategies, and 6) due to the budget constraints and limited resource environment, how to direct resources to where they will have the greatest impact and how do these strategies rank by cost effectiveness. To answer these questions, there is a need to evaluate the existing and future corridor conditions performance based on the existing and forecasting data. This paper uses a macroscopic simulation model to analyze the existing and future conditions performance. After identifying problems, the corresponding improvement strategies are proposed. This paper uses the life cycle cost-effectiveness analysis (CEA) to rank different improvement strategies and find the most cost-effective strategies. The main contribution of this paper is not the specific techniques, but the demonstration of performing the techniques in integrated corridor system management.
