Procedures and Guidelines for Rehabilitation of Existing Freeway-Arterial Highway Interchanges. Volume II. Design Procedures for Rehabilitation of Freeway-Arterial Interchanges

摘要

This volume presents design procedures that can be used to improve existing interchanges with traffic operational or safety problems. The procedures are intended primarily for application to freeway-arterial interchanges located in urban and suburban areas. However, similar procedures would be appropriate for freeway-freeway interchanges and for interchanges located in rural areas. The report presents procedures for each step in the interchange rehabilitation process including identification of interchanges with traffic operational or safety problems; identification of specific deficiencies through engineering studies; identification of improvement alternatives; quantification of the effects of improvement alternatives; evaluation of alternatives and selection of the best; implementation of the improvement project; and, evaluation of the improvement project.
