Freeway to Arterial Interfaces

Due to the population growth and the extreme growth in car ownership per capita, network-wide congestion is increasingly growing and spreading. Therefore, transportation agencies are actively seeking innovative strategies to manage the growing traffic on rural and urban roadways. Ensuring a safe and efficient transportation network with adequate accessibility to neighbors and local businesses is a challenge that all the transportation jurisdictions are struggling with. This chapter focuses on the state of the art for mitigating the mobility issues at freeway and arterial levels. Specifically, four areas of interest are explored: at the freeway level, innovative ITS technologies, and data-driven strategies for estimating freeway travel time, and the potential applications of travel time as one of the most crucial measures for monitoring and regulating traffic. At the arterial level, strategies, and technologies to monitor, maintain, and improve traffic conditions at intersections and corridors, and finally, the recent effort in advancing the Integrated Corridor Management Systems for managing traffic congestion as an integrated system for improving network-wide traffic safety and mobility, and quality of life.
