Abstract

Information were utilized to estimate accident frequencies for entire ramps, as a function of speed-change lane length, among other variables. An economic analysis is then presented to evaluate the cost-effectiveness of extending speed-change lanes. The method allows a highway planner or designer to assess the benefits of improving the safety of interchanges considered for reconstruction, or when experiencing higher than average accident frequencies, without requiring existing accident records.
