Non-intrusive detection, the way forward

Abstract

With an increasing demand on our transportation networks, it is important to design and implement effective detection systems, for numerous reasons it can also be advantageous if these systems can be non-intrusive. Implementation of a detection system needs careful consideration, as there is a wide variety of technologies available on the market, each with its own characteristic strength and weakness. The strengths of a specific technology, will in most cases determine whether the detection system is suitable for the desired application. Other factors which can easily be overlooked, during the planning of detection system installation is: life span, maintenance and operating costs of the equipment. Environmental influences are also important to bear in mind, as the specific environment into which a chosen system is to be deployed, will in many instances affect the choice of the detection system. From the most basic detection technologies to more advanced systems. We provide a series of examples, based on tests conducted throughout South Africa and also studies conducted overseas. These examples demonstrate how these detection systems are deployed, and how they operate in a real life environment. The intent of this paper is to present an approach to the design and implementation of a detection system, ensuring that we make use of the best detection solutions.
