Theme 4: Road Engineering and Speed Management

These projects address the contribution of speed to accident risk and the ways in which the enforcement of speed limits and road safety engineering measures can reduce casualties most effectively.

Interaction between speed choice and road environment (Road safety research report No. 100)

This project aimed to identify the most effective, low-cost speed-reducing measures for a selection of urban and rural environments. The overall approach consisted of three sequential steps: Stage 1 - a review of previous experience with speed-reduction treatments; Stage 2 - applying expert judgement to the information gathered in Stage 1 to design a range of treatments for each of the problem areas and road types; and Stage 3 - simulator experiments to identify the most promising treatments.
