REDUCING THE QUEUES

This article describes some recent developments in traffic detection, surveillance, and control systems, which are designed to minimise the congestion being caused by increasing traffic flows in urban areas. These innovations are motivated by a belief that all kinds of road traffic will be increasingly controlled everywhere in terms of speed and access. Accurate and reliable movement sensing will be essential to highway planners, toll operators, system managers, and law enforcers. In a major project in Singapore, there are 130 sites using over 1000 Traffic 2000 piezo-electric axle sensors, in conjunction with inductive loops and a Marksman 660 classifying machine. The Canadian company Delcan Corporation has been busy installing traffic control and surveillance systems worldwide for example in China, Hong Kong, and Taiwan. Delcan is also supervising the acceptance testing of a SCOOT urban traffic control system for Dubai Municipality in the United Arab Emirates. Gertrude (General Electronic Regulation for Urban Defense of Environment) is marketing another system claiming remarkable traffic and environmental results. This traffic control system relies on a very dense transmission network linking its many electronic devices and is being applied in several cities in France and Portugal.
