Capacity Analysis Techniques for Design and Operation of Freeway Facilities.

摘要

In design of freeways the various geometric features,the configuration and spacing of interchanges,the number and arrangement of lanes,must be determined largely through level-of-service and capacity analyses. A special feature of the technique involves the grouping of successive ramps along a freeway into overlapping pairs. The influence of one ramp upon another is then isolated and each component of the freeway is dealt with by a separate analysis. Finally the results are combined to reach a composite solution for design of the complete freeway facility or for it as an operating system.
