This project, categorized as a Product Test, involved the system development and testing of a communication device based upon the ReFLEX Narrowband PCS technology commonly used in two-way pagers. The pager-based communication device was tested with three different remote sensors in the Boston Metropolitan area with assistance and support from the Massachusetts Highway Department. This product is cost effective for transmitting data from Highway Performance Monitoring System sites, and in event-based data transmissions such as incidents, weather, equipment failure, etc. It can be a cost-effective alternative in typical ITS application in situations when traditional methods such as telephone, spread-spectrum or cellular either are technical infeasible or have high installation costs. |
