Abstract

Transport is now firmly established in the political agenda, as public awareness grows of the impact of congestion on towns and cities and the people who live and work in them. Consequently, transport policies are evolving, and new ways of managing transport networks are needed to support this change cost effectively.

Use of the Urban Traffic Management and Control (UTMC) Technical Specification will be one way of assisting authorities to meet this need. The Technical Specification for UTMC systems has now been jointly produced by the Traffic Director for London and Department of Transport and aims to encourage the development and implementation of UTMC systems.

To achieve this, the UTMC Technical Specification defines a framework for a computer "network". This network supports the inter-connection of a wide range of equipment which provide facilities such as traffic signal control and variable message signs (VMS). The key aspect is that all the components communicate with each other in a standard and, in computer terminology, "open" manner that is defined in the UTMC Technical Specification. It includes a Data Dictionary which defines the structure and meaning of data used in UTMC systems.

Figure 1.1 shows an example UTMC system. It shows how different equipment could be connected together using the UTMC network, sharing communications and information which can be accessed by operators and other systems and services.
