CELLULAR BASED TRAFFIC SURVEILLANCE -- THE WASHINGTON, D.C. AREA OPERATIONAL TEST

This paper describes the conceptual design and preliminary engineering associated with the operational test of cellular phones as a traffic surveillance tool. The FHWA sponsored project is a joint initiative of Maryland State Highway Administration, Virginia Department of Transportation, Engineering Research Associates (ERA), Bell Atlantic Mobile and Farradyne Systems, Inc. With over 12 million cellular phones currently in operation the proposed system design has a potential to provide a cheap source of traffic data that will improve in the future. The surveillance test is made up of two major elements: the cell system and the traffic system. The cell system derives vehicle locations and various cellular activity parameters. The traffic system monitors this data and interprets the information as traffic parameters that are useful to traffic control and IVHS. These two systems maintain a dialog. Anomalous cell activity is used as a potential incident indicator. When a potential incident is indicated, the traffic system requests additional data from particular cell sites to provide increased confidence in the probability that the incident is real. This paper outlines this process.
