摘要：	Smart call boxes are an enhanced version of devices used as emergency call boxes in California. The overall system consists of a microprocessor, a cellular communications transceiver, solar power sources, data collection devices, maintenance computers, and data recording systems. The Smart Call Box Field Operational Test (FOT) evaluated the feasibility and cost-effectiveness of using smart call boxes for five data processing and transmission tasks: traffic census, incident detection, hazardous weather reporting, changeable message sign control, and video surveillance. Evaluation focused on cost-effectiveness, with effectiveness understood to include both functional adequacy and reliability and costs to include capital costs. telephone charges, and maintenance costs.
