| Abstract | This research was performed to complete and advance the status of recently developed procedures for analysis and design of weaving sections (known as the Leisch method and-initially published in the 1979 issue of ITE Journal). The objective was to enlarge upon and complete the earlier work through calibration of the method by using data from the BPR Weaving Area Study, NCHRP Project 3-15, and studies of Institute for Research of Pennsylvania State College; also to expand and refine the initial statistical analysis to provide full documentation; as well as to update the nomographs previously developed, including a demonstration of problem solutions for application. The research and development conducted closely verified the previous work, and largely expanded on documentation and application of the procedure. The general framework of the procedure is patterned to some degree upon the 1965 Highway Capacity Manual in order to maintain familiarity and ease of applica-tion. This was verified in using the technique, allowing fer relatively siMple and rapid solutions. The method is applica6le to both design and operational analysis situations, and oriented to be in consonance with .ll.ASHTO Design Policies. The report is presented in two parts: Volume 1--covering the development and verification of the procedure; and Volume 2--providing a users guide to demonstrate the solution of a variety of weaving problems. |
