Urban Traffic Management Control (UTMC) computerised systems are being used throughout the UK to improve the flow of traffic in towns and cities. They are designed to link communications between various components of traffic management, such as traffic signal control, air quality monitoring, car park management and bus priority. Where these systems are optimised, congestion has improved and lower pollutant emissions are likely.
An example of this can been seen in the Leicestershire case study available below.
Average traffic delay is reduced by 20% on the implementation of a SCOOT (Split Cycle and Offset Optimisation Technique) system reducing idling emissions. Other systems are often used by local authorities to control traffic light signals in more isolated junctions e.g. MOVA (Microprocessor Optimised Vehicle Actuation) and on average showed a 13% decrease in delay.
