A Collaborative Software Framework Design in Supporting GLITS I-75 Integrated Freeway Arterial Operation Project

摘要

This paper summarizes the software design within the GLITS (Great Lakes ITS) I-75 Freeway and Arterial Integration project. The GLITS I-75 Project was a pilot project of the Integrated Corridor Management (ICM) aimed at coordinating freeway and arterial operations to quickly release freeway bottlenecks by optimizing the parallel arterial road’s capability to accommodate traffic diversion from the freeway. This software framework links two different types of traffic management systems (freeway and arterial) and smoothly integrates corresponding functions together, minimizing the changes of their existing architectures. The paper will include the following aspects: 1) Functions requested to coordinate the freeway and arterial operations within GLITS I-75 Project; 2) Existing software architecture analysis for both freeway management and arterial management; 3) Concept of the collaborative software framework; and 4) GLITS I-75 Project software design summary.
