Conduct a critical review of the SWOV report with a view to giving the Department guidance on:
* the validity of the conclusions from this report;
* the need for further analysis of the existing data; and,
* the need for further research.
The use of Daytime Running Lamps (DRL's) is claimed to reduce the number of road accidents, particularly those associated with certain manoeuvres.
A number of countries have introduced requirements for vehicles to use DRL's or dipped beam headlamps during the daytime. Analysis of the consequential accident reduction would appear to suggest that the use of such lamps during the daytime is beneficial, but that the benefit increases with an increase in latitude. However, in certain cases, re-examination of the original data would suggest that the benefits may have been significantly exaggerated. Although benefits have been demonstrated, the reasons have not necessarily been fully explained, nor have the potential costs been calculated.
On the basis of the 'demonstrated' benefits, proposals are being put forward for the mandatory fitment of DRL's. However, most of the benefits have been calculated on the basis of dipped-beam headlamps being used, and these lamps have different attributes to the DRL's. These different attributes might affect the potential benefits and costs of such lamps.
Towards the end of 1997, SWOV published a report entitled "The Safety Effects of Daytime Running Lamps". The report was funded by the EC and sought to establish the benefits of DRL's. The purpose of this project is to conduct a detailed review of the SWOV report.
