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.
