The Crescent Project element of the HELP Program is a bi-national multi-jurisdictional cooperative research and demonstration initiative involving the public and private sectors in an application of advanced technologies for the creation of an integrated heavy vehicle management system. The initiative is a leading example of the commercial vehicle operations (CVO) aspect of the Intelligent Vehicle Highway Systems (IVHS) concept. Some of the advanced technologies demonstrated in this project include: automatic vehicle identification (AVI); weigh in motion (WIM); automatic vehicle classification (AVC); and data communication networks and systems integration. The HELP program, initiated in the early 1980s, consisted of three phases which included: assessing the feasibility of the concept, technical studies involving laboratory and field tests, and a demonstration phase. Perhaps the most significant activity of the project centered on the subject of institutional arrangements, associated with current operational policies and practices, within both government and industry sectors. The demonstration element of the program, referred to as the Crescent Demonstration Project, began in 1991 and involved 6 U.S. states and one Canadian province. This project was phased into full scale operation over a three year period. |
