DESIGN-SYNTHESIS APPROACH TO TRANSIT PLANNING

Mark H Scheibe, Gordon W. Schultz

Open publisher page 0 citations

Abstract

Transportation system design should be oriented toward meeting specific local and regional objectives. In most current planning, objectives are used only to evaluate selected alternatives. This paper presents a design-synthesis approach to transit planning, which allows objectives to be input directly to the process and generates a transit system incorporating characteristics that are selected to optimize the attainment of specific service and cost objectives. The design-synthesis technique specifies transit service in the abstract so that characteristics of service such as frequency, headway, travel speed, and fare can be examined individually without being constrained to a specific system alternative. The paper reports successful applications of the approach in (a) identifying short-range transit improvements for San Diego and Denver and (b) designing long-range transit alternatives for Denver.
