Abstract:This volume presents evaluations of the traffic operational and safety effectiveness of 40 recent interchange rehabilitation projects. All of the projects involved geometric design modifications at freeway-arterial interchanges in urban and suburban areas. The evaluations, presented in case study form, describe the geometrics of each interchange, the traffic operational safety problems that existed before the improvement, the interchange rehabilitation alternatives considered (including the one finally selected) and the operational and safety effectiveness of the rehabilitation project. The introductory portions of the volume describe the selection of the interchange rehabilitation projects and the procedures used for traffic operational and safety analyses. This volume is the third in a series. The other volumes in the series are: Volume 1-FHWA/RD-81/103 Executive Summary; Volume 2-FHWA/RD-81/104 Design Procedures; and Volume 4-FHWA/RD-81/106 Research Report.
