| Abstract | The objectives of this research project were to develop improved design procedures and guidelines for major (i.e., Freeway-to-freeway) interchanges through the examination and analysis of existing design procedures and current freeway operational characteristics. Pertinent informantion was gathered through a review of the literature, conversations with and workshop participation by practicing design engineers and traffic operations specialists, and through written questionnaires. The criteria and guidelines used in the design of major interchanges at both the overall configuration level and the individual component level (such as entrances, exits, lane drops, major forks) are reviewed; conclusions and recommendations for future practices are stated. Freeway traffic control systems are examined in the context of major interchange design and operation, and the implications of various systems are explained. A methodology for interchange evaluation using decision theory and tradeoff analyses is presented, with example applications. Extensive case studies of a lane drop and exit ramps at a major interchange are described to illustrate the manner in which the recommended quidelines might be applied in practice. Two sample "Fact Sheets" illustrating the manner in which design experience information might be disseminated to the design community are included. A bibliography of over 200 pertinent references accompanies the report. This report is in 3 volumes. |
