Research and evaluation of an integrated vehicle detector

Abstract: The article presents the method and results of an evaluation of an integrated vehicle detector. The device under study represents the latest trend in detector construction. Several detection methods have been applied in a single device. The tested device utilizes: passive infrared (PIR), ultrasound, and electromagnetic microwave radiation. The purpose of the research was to determine the accuracy with which the TT 298 vehicle detector acquires data. The following were evaluated: vehicle counting, determination of vehicle type structure, and measurement of vehicle speeds.The functionality of the device and the ease of collecting and analyzing measurement results were analyzed.
1. INTRODUCTION
Traffic control – as a field of knowledge – gained importance in the second half of the last century as a result of the sudden increase in the number of means of transport.
Advanced ITS subsystems such as: traveler information systems, traffic control systems on expressways and street networks, emergency response systems, and parking space management systems are increasingly effectively using data that reflect current traffic conditions [1]. Vehicle detectors that acquire such data are an integral part of every modern traffic management system [5].
There is no single, universal device that is optimal for all applications.
In addition to induction loops, magnetic detectors, video detectors, microwave detectors, ultrasonic detectors, infrared (PIR) detectors, pneumatic, piezoelectric, laser, ultrasonic, and many others are used [6].
As in every field of technology, there is continuous progress; existing detection methods are being improved, and new technologies and devices are being proposed [8].
The article presents the method and results of an evaluation of an integrated vehicle detector.
The device under study represents the latest trend in detector construction, where three detection methods are used in a single device. In Poland, no evaluation of this type of detector has been performed. A practical effect of the presented work was the preparation of a test stand for traffic parameters used for didactic purposes and conducting research work [9]. (…)
