A Collaborative Software Framework Design in Supporting GLITS I-75 IntegratedFreeway & Arterial Operation Project

摘要

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