The report discusses the findings of an investigation into the effect of street lighting on accidents in Hamburg. Accident rates are compared for sections of the same road where one is lit and the other is not. Lower accident rates were found over the section where lighting had been installed both at the interchange and over lengths of motorway. The effect of an improvement in lighting by replacing gas lamps with electric lighting was investigated by comparing their accident rates after improvement with those on similar roads where the existing electric lighting remained unchanged. A significant reduction of accidents occurred after the lighting had been improved. It is shown that considerable economic benefit can be obtained from the introduction or improvement of lighting. Conversely it is shown that the effect of reduced lighting at periods of low traffic volume results in a costly increase in accidents, far exceeding the saving in lighting costs. /TRRL/
