Abstract: In this research project we are developing a roadway detection system that can directly determineO/D data non-intrusively without violating the public's privacy (as in license plate recognitionsystems). While we have previously developed a real-time laser-based non-intrusive detectionsystem for measurement of true travel time on the highway, we improved the system further. Afeed-back loop, using microchip control, was introduced into the system. This makes the systemeasy to use. The mechanical components were also improved to increase the precision of thesystem. Software to display the information or communicate with other research groups wasupdated.
