Abstract
Currently, large inductance coils buried underground are commonly used to detect passing vehicles at road toll stations. The inductance-based systems are vulnerable to environmental magnetic interference and hence are inaccurate in counting passing vehicles. Also they cannot categorise the vehicles. This paper presents a capacitance sensor array, which has been developed not only for detection of passing vehicles but also for identification of types of the vehicles. Together with infrared sensors, the new system can be used to control a road barrier and to keep a record of passed vehicles through a driveway accurately. Tests have demonstrated that it is more reliable than the inductance-based systems. © 2007 IOP Publishing Ltd.
