DEVELOPMENT OF THE RELATIONSHIP BETWEEN THE POSTED SPEED LIMIT AND ACCIDENTS ON MARYLAND ROADS

This study was a research effort conducted to study the effect that posted speed limits have on the number of accidents and type of collisions on the roadways in Maryland. The purpose of this study was to uncover a relationship between the posted speed limit and the geometric characteristics of Interstate, U.S., and Maryalnd roads which would enable the State Highway Administration to project consequences of lower and higher speed limits. The resulting relationship was to serve as a basis upon which requests for posted speed limit changes could be made. The resulting analysis did not indicate any first order linear relationship between accidents, speed and geometric characteristics for Interstate and U.S. roadways. Relative and Absolute risk indices were developed for different road characteristics which indicate the effect on the accident frequency of changing the posted speed limit.
