Abstract:

This report describes a cost-effective data collection system for Caltrans 170 traffic signal ; controller. The data collection system is based on TCP/IP communication over existing ; low-cost mobile communication networks and Motorola® iDEN1 mobile handsets. An ; adaptive wireless flow control protocol is developed to ensure reliable continuously ; communication over unstable wireless link. The system is fully integrated with Caltrans ; 170 signal controllers and its CTNet server program. Lab testing shows that with the ; adaptive flow control protocol, each handset can deliver data fetched from signal ; controllers at a period of 200ms continuously over 95% of the time. One set of data ; collection device costs less than $100 and its monthly cost can be as low as $10.
