Abstract

A summary is presented of the efforts and conclusions developed in a study which included a review of available left-turn analysis procedures, comparative evaluation of several methods, and field testing of one technique. Existing analysis methods are noted, and guidance provided by the Australian Road Capacity Guide and the 1965 Highway Capacity Manual method are discussed. The Texas Model, a microscopic traffic simulation package used to develop a set of left-turn analysis procedures, is described. An analysis procedure based on this model is compared with the 1985 Highway Capacity Manual. Particular reference is made to single-lane approaches without turn bays or phases, and to single- and multiple-lane approaches with turn bays.
