Samenvatting
This system operates by means of electromagnetic wave in the lane marker system for detecting the lateral position of a vehicle in a highway lane. The previous system, which was a lane marker utilising resonance reflective electromagnetic wave and was introduced in last year's ITS World Conference 1999 in Toronto, possessed good detection performance but was susceptible to interference by nearby vehicles. Also, the applicable vehicle speed was 180km/h or slower. The new system described here solves the problem mentioned above with improved detection performance, and is considered fully usable in a real application due to its excellent detection performance, ease of installation of the lane markers and detectors, and the long service life.
