Abstract

Traffic congestion in urban areas is a serious problem. It affects both the quality of life and economic well-being of the areas. The trends in car ownership and travel demand indicate that the pressure on the road space will further increase. There is increased awareness of the impact of congestion on air pollution; danger to pedestrians and cyclists and; and unpredictable delays to buses and commercial vehicles.

UTC systems have played an important role in minimising the impact of congestion in urban areas. They have provided a very cost effective means of achieving significant savings in delay and reducing journey times in congested networks. The performance of the systems have been judged on the basis of how effective they have been in maximising throughput of the network and minimising delay.

There is now a need for a more comprehensive approach to traffic management for congested networks. The UTMC specifications are being developed with the aim of providing a framework for a number of different systems to work cohesively to meet the emerging objectives for managing traffic in congested networks. In this paper, the need for UTMC is systems first examined. This is done in context of emerging transport objectives. The potential functions within UTMC systems are then outlined.

The paper also outlines the key elements of the UTMC specifications. The benefits to suppliers and users of UTMC are also highlighted.
