This paper develops the methodology and compares door-to- door trip characteristics of some urban transportation modal combinations that are currently in use, are being considered, or appear to hold near-term promise for corridor travel in large U.S. cities oriented to the central business district. The cost and travel time of various options are developed separately for residential line-haul, and downtown trip components. Then they are combined selectively to explore relative merits of door-to-door alternatives. The analysis addresses the many possible variations in corridor length, central business district size, daily volume level, and temporal flow pattern. Furthermore, the sensitivity of costs with respect to changes in design sepcifications, operating policy, automation, and nature of construction is explored. A case study compares various options for Metro in the Washington, D.C., metropolitan area. The marginal costs of busway-based systems are lower than those of systems based on rail rapid transit. Automation is not likely to lower rail rapid transit operating costs dramatically. High-performance, exclusive busways require substantial initial investment but are less costly and faster than rail rapid transit in almost all environments and volume levels. Residential collection with jitneys costs only a little more than residential collection with buses and provides much better service. Car pools provide the least expensive service and attractive door-to-door time.
