Smart Call Box Field Operational Test Evaluation. Subtest Reports

摘要

Smart call boxes are an enhanced version of devices used as emergency call boxes211u001ein California. The overall system consists of a microprocessor, a cellular 211u001ecommunications transceiver, solar power sources, data collection devices, 211u001emaintenance computers, and data recording systems. The Smart Call Box Field 211u001eOperational Test (FOT) evaluated the feasibility and cost-effectiveness of using 211u001esmart call boxes for five data processing and transmission tasks: traffic census, 211u001eincident detection, hazardous weather reporting, changeable message sign (CMS) 211u001econtrol, and video surveillance. In addition, institutional issues were analyzed 211u001eas a part of the FOT. This report presents detailed evaluation results for the 211u001eindividual subtests. A separate Summary Report presents an overview of the FOT. 211u001eMost of the traffic census systems functioned adequately but suffered from 211u001ereliability problems. None of the incident detection systems functioned 211u001ecorrectly, but the problems appear to be minor. Hazardous weather detection and 211u001ereporting systems functioned adequately, but could be improved by several 211u001eproposed design enhancements.
