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.
The effects of speed cameras: how drivers respond (No.11)
This study examines the effectiveness of various strategies related to the deployment of speed cameras, and how different types of driver responded to cameras and perceived their operation.

Congestion and accident risk (No. 44) (533 kb)
A study of the extent to which accident risk increased in congested traffic. Despite a presumption that risk was higher in congested conditions, with the exception of motorway sites, accident rates are actually lower.

Assessing the casualty reduction performance of local highway authorities (No53) (454 kb)
A study identifying the contextual, organisational, resource and technical factors which lead to the exceptionally good, or poor, performance of a local highway authority in reducing casualties.
