We have developed a vehicle location estimation sensor with a pair of leaky coaxial cables for traffic survillance system. Recently there has been a great demand of traffic surveillance sensor that can be used under a bad weather condition where traffic monitoring camera cannot be used. Therefore, we propose a two-dimensional location estimation method using a pair of leaky coaxial cables (LCX). Once the two-dimensional location estimation is realized, the present method will be able to measure every vehicle position and analyze the vehicle density on a lane for detecting a traffic jam and a traffic accident. In this paper, the position of the car is measured based on the time of arrival techniques. Experiment results are presented to show that the proposed method is indeed feasible.
