URBAN CONGESTION STUDY 1976, INTERIM REPORT (THIRTEEN TOWNS AND CITIES IN ENGLAND - EXCLUDING LONDON)

The study presents results of the 1976 urban congestion study covering 8 major cities and 5 conurbations in the UK. The surveys collected information over time on speeds, flows, composition of traffic, vehicles parked on street and stop times for peak and off-peak periods for weekdays in each study year. Although it is difficult to define congestion absolutely, speeds, flows, and stop times could be used as parameters in its assessment. The main findings for the 1976 study showed that average speeds in free standing towns and conurbations seem to have reduced with substantial increases in speeds to a level which matched those found in the free standing towns. Flows in the free standing towns continued to increase roughly in line with vehicle growth yet with continued, though smaller, speed increases. A number of factors probably contributed to these results, in addition to new roads and extended traffic management. These include changes in traffic composition giving higher proportions of faster vehicles, systematic improvement in vehicle performance and the movement of population and employment from inner areas, a trend which was particularly marked in the conurbations. The study also confirmed that a reduction took place in the number of buses on the network with the greatest reduction occurring in the peak periods. peak periods. /TRRL/
