Abstract

The automatic speed camera activity has resulted in a considerable reduction of personal injury accidents and injured persons. The change is statistically significant. The greatest reduction, approximately 50%, is in fatal accidents and fatalities. The effects of camera enforcement on the average speed have been estimated using the speed measurements before and after the installation of the camera boxes. The enforcement method has resulted in significant speed reductions on the camera monitored sections of road. Great speed reductions are shown both at and between the camera boxes. Speeds can be expected to be reduced at the boxes by just over 8 km/hr and between the boxes by nearly 5 km/hr if the average speed before speed camera enforcement began was 95 km/hr. The basis for the effect estimates is comprised of the total result from the 14 research stretches that have been in operation in 2002/2003 and the four stretches that were monitored by cameras for all of 2003. The combined road distance is about 340 kilometers. The study shows socioeconomic savings of 164 million SEK per year. The costs in the form of investments, operations, and increased travel time total nearly 60 million SEK and savings in the form of reduced costs for personal injuries, vehicles, and the environment make up about 244 million SEK.
