Abstract:The project involved the installation of HAR transmitters in Baton Rouge and Lake Charles. The transmitter sites were located at key entry points to each metropolitan area. At the conclusion of the project all seven of the transmitter units were fully broadcast capable. They were, however, somewhat limited in terms of timeliness of broadcast information due to the lack of real-time traffic data and manpower limitations required to operate the system.
The project included a review of literature and practices related to the development and application of HAR systems in the United States to address the applicability of existing commercially available HAR systems as well as the specific planning, placement, and operational requirements necessary to implement an effective HAR system. The review also addressed the concept of using HAR in combination with other advanced technologies such as GPS, video suweillance, radar, and pavement loop detection to determine future means of integrating a real-time traffic data collection/processing capability with HAR.
The project also included the development of guidelines for monitoring the system, suggested message information content, and training for personnel responsible for the operation and maintenance of the system as well as equipment specifications, personnel operating requirements and the acquisition of a Federal Communications Commission (FCC) broadcast license.
