Evaluation Method Investigation for Non-Traditional Traffic Monitoring Technology

This paper proposes an effective and easily-implemented evaluation method to assess the performance of a mobile probe traffic monitoring system. The authors explain how sample size will affect the system performance and how to determine the criteria and threshold for system acceptance testing. They note that several research programs and traffic agencies are actively in exploring the feasibility of deploying such a traffic information system with this technology. Cell phone data can now to used to give a fairly good estimate of travel time in urban, suburban, and rural regions. Furthermore, the amount of cell phone subscribers has been increasing, and this improves the feasibility of estimating traffic state by using cell phones as probes. The authors outline the potential benefits from using cell phones as probes to estimate real-time traffic state including: significant cost savings due to the use of existing wireless communication system; scalability to future wireless technology requiring only minor upgrading; and combining the basic geographic distribution data of wireless communication network components and the geographic information system (GIS) of the roadway network can improve the accuracy of mapping tracked cellular phones into roadway links.
