Linking Freeway and Arterial Data - Data Archiving Testing in Supporting Coordinated Freeway and Arterial Operations

Overall traffic delays are increasing in most of the US surface transportation systems. The Coordinated Freeway and Arterial (CFA) Operations is a new initiative that is trying to integrate freeway and arterial operations via data sharing. This paper presents part of the development from the Great Lakes Intelligent Transportation System I-75 Integrated Corridor (GLITS I-75) project, which is as pilot project of CFA intending to evaluate the feasibility of managing traffic in a multi-jurisdictional freeway and arterial corridor under varying traffic conditions and traffic diversion scenarios. The paper focused on testing the integrated freeway and arterial data archiving system in investigating their potential capability in supporting CFA scenarios. First, the concept of the GLITS I-75 Project is summarized. Second, ITS data archiving technologies were tested at the Road Commission for Oakland County´s Traffic Operation Center (RCOC TOC). Finally, in particularly, the potential linkage of archived freeway and arterial data was discussed to show how its potential benefits of the CFA operations.
