A Punctilious Detection Method for Measuring Vehicles' Speeds

This paper presents a development of a highly sensitive magnetometer system that can be used for speed detection of a high speed moving object such as vehicles. The system model consists of two light weight, tiny size and very low power consumption magnetic sensors which are separated by 1 meter from each other. The whole system can be placed either beneath the surface of the road or in parallel beside the road. The two magnetic sensors detect intricate magnetic patterns which are produced by moving objects, individually and successively. The collected data from the sensors is analyzed in detail to achieve appropriate correlation coefficients which leads to measure the speed, precisely. A computer-based heuristic algorithm has been designed to handle the data that has been collected from the sensors, rapidly. Experiments have been conducted to examine the system's performance and to validate the system's operation
