In order to save electricity during the winter of 1973-74 most highway authorities reduced the level of street lighting by 50 per cent. However three boroughs in the greater London area chose not to make these reductions, enabling a comparison of accidents to be made between lit and unlit boroughs. The comparison is not straightforward because all boroughs were forced to make 50 per cent cuts on trunk and metropolitan roads. The evidence suggests that there was an increase in after-dark accidents but the traffic conditions were unusual and direct comparison of fully lit roads with those only partly lit showed that the difference was not significant. When all roads were considered, there were significant increases in the proportion of pedestrian accidents and fatal accidents occurring in the dark. Accidents on major roads appear to have been worse affected by the lighting cuts. The observations of this study do not prove that street lighting cuts changed the accident pattern, but they do conform with intuitive expectations and may help authorities to minimise additional accident risks when considering cuts. /TRRL/
