Determination of vehicle origins and destinations have long been a goal and a tool for traffic planners. Recently there has been an increase in the use of machine vision systems (automatic license plate readers) for determining origins and destinations. The original work in this area involved recording traffic on s-video compatible tape formats (e.g. s-VHS and Hi-8mm). Recently the use of real time analysis of traffic flows has been implemented. This paper describes the implementation of a system to acquire license plate information on the Tacoma Narrows Bridge, in Washington state. The paper describes the system installation, the system architecture, the data handling and mail outs and some preliminary results.
