Samenvatting
This report describes the results of a literature review undertaken to determine the cost effectiveness of a range of safety improvements for rural roads. Safety benefit to cost ratios have been determined for eleven categories of improvements to the road and roadside, including road delineation, signage, pavement resurfacing, shoulder and lane widening, overtaking lanes, geometric improvements, roadside hazard management, construction of medians and barriers, intersection treatments, railway crossing treatments, and new road construction. Deficiencies in available research have been identified and recommendations on future research provided. (A)
