While the traffic control and delay minimisation benefits of UTC systems such as SCOOT and TRANSYT have been clearly demonstrated, the road safety implications and effects on other road users are less well established. The main objective of this study is to assess any SCOOT effect on safety. Appropriate accident statistics for six UK areas (Worcester, Westminster, Maidstone, Southampton, Cambridge and Coventry) were examined and any differences in the data for the periods before and after the installation of SCOOT were identified. The significance of any changes in accident frequencies were assessed in relation to accident trends in selected control areas. There was no evidence that SCOOT has increased the frequency was no evidence that SCOOT has increased the frequency of pedestrian accidents or accidents at Pelican and Zebra crossings in comparison with the selected control areas. There was limited evidence that pedestrian safety in areas operating SCOOT has improved less rapidly than for all A roads with 30 or 40 mph speed limits in Southern England.
