EVERY BIT COUNTS: ENHANCING THE BENEFITS OF UTC THROUGH DISTRIBUTED APPLICATIONS

The development of the Urban Traffic Management and Control (UTMC) system in Nottingham shows the added value to be gained by linking urban traffic control (UTC) with other systems such as automatic vehicle location and passenger information schemes. Recent collaboration between Nottingham Trent University (NTU) and Nottingham Traffic Control Centre (NTCC) has resulted in the development of DIME (DIstributed Memory Environment) to access real-time traffic data collected by the SCOOT UTC computers. DIME has been designed to support a wide range of traffic and transport applications, and it allows various telematic applications to communicate with each other. It is a distributed computing system with two components: (1) the shared memory manager (SMM) task owning the shared data buffers; and (2) the applications program interface (DIME-API) libraries linking user applications with the SMM. The current set of applications interfaced to SCOOT via DIME include a predictive macroscopic simulator, a portable traffic-travel information system, and a microscopic traffic simulator. Experience of the system shows that variation of travel times seems to be important in persuading drivers to use public transport, and urban sustainability can be greatly enhanced by a UTC interface based on a geographical information system (GIS).
