Systems for detecting vehicle positions using lane markers embedded in roads are being researched in various countries as an AHS (Advanced Cruise-Assist Highway System) element technology. Systems which allow running vehicles to detect their position in the lane as well as the presence and positions of stop lines and other information in real time are important infrastructural technologies for system development to realise AHS user services on Smartways. Commissioned by the Public Works Research Institute (PWRI) of the Ministry of Construction, AHSRA has researched technologies for real-time detection of vehicle positions since 1996. In 1999, AHSRA selected a lane marker system to be used in the AHS proving tests, which will be performed from autumn to winter of 2000, and after improvements to allow use in the field, this system was installed at the PWRI proving test site. This paper presents an overview and the specifications and performance of the lane markers and the marker detectors mounted in test vehicles that will be used for the proving tests.
