REHABILITATION OF EXISTING FREEWAY-ARTERIAL HIGHWAY INTERCHANGES

The results of a study of interchange rehabilitation projects at freeway-arterial interchanges are presented. The study included the evaluation of 40 recent interchange rehabilitation projects and the development of recommended design procedures and guidelines for interchange rehabilitation projects. The significance of arterial crossroads and crossroad ramp terminals as a source of traffic operational and safety problems at freeway-arterial interchanges in emphasized. An analysis of the safety effectiveness of interchange rehabilitation projects was conducted, and safety measures of effectiveness for major and minor geometric modifications are reported. An overview of the recommended design procedures for interchange rehabilitation projects is also presented. The recommended procedures address six stages of the design process: identify interchanges with operational or safety problems, study problem locations and identify specific deficiencies, identify improvement alternatives, quantify the effects of the improvement alternative, evaluate the alternatives and select the best one, and implement the improvement and evaluate its effectiveness.
