DEVELOPMENT AND EXPERIMENTS OF SIDEWARD-RADIATION-TYPE OPTICAL VEHICLE SENSOR

An optical vehicle sensor is used to sense vehicles running on the road and to carry out two-way information communication with an on-vehicle unit while each vehicle is driven. In Japan, overhead-type optical vehicle sensors (installed directly above each lane) were put into practical use in 1992. It was found that installation of these types of sensors on a multi-lane road needed improvements for better appearance of streets and easier maintenance. In June 1993, development of the sideward-radiation-type optical sensor was completed for installation on a multi-lane road. In outdoor experiments using vehicles, successful results were obtained. This paper presents the features of the developed sideward-radiation-type optical vehicle sensor, the conditions and results of experiments (especially communication function experiments), and consideration for further improvements.
