The professional costs associated with developing, tabulating, and evaluating alternatives in the execution of a highway location planning study have now become large enough to be considered a problem. A method is presented that minimizes the wasted efforts (and project costs) associated with testing in location planning studies and at the same time makes the study process more accurate and precise. This method of highway location selection offers the transportation planner a computer-assisted technique that can generate and then search through a large number of generated highway locations to identify optimal solutions. The traffic analysis zone is the basic element of which generated locations are composed. Zone deficiencies are determined for each zone and then used to determine zone-pair connectivities that represent the degree of importance of connecting deficient zones by a highway. A measure of effectiveness, defined as the aggregate connectivity of a location divided by its length, is used to approximate benefit/cost ratios in evaluating each generated location. The process also includes methods to account for highway-related costs (or benefits) of social, environmental, and economic impacts. This process allows an estimate of the highway benefits of a large number of location alternatives without running traffic assignments for each generated location. /Author/
