Abstract:

The purpose of this study was to compare forms of multi-modal travel by means of a case study of a freeway corridor in the Phoenix metropolitan region. The corridor selected was State Route 51. The SR 51 case study relied on existing data, modeled situations, and cost estimates to determine the most cost effective choice for multi-modal travel. Existing volume data was provided by Arizona Department of Transportation’s (AzDOT) Freeway Management System (FMS) and supplemented by a micro-simulation study previously conducted for AzDOT concerning the operations of the existing high-occupancy vehicle (HOV) lanes. Cost data were coalesced from literature review material and transportation data sources exclusive to Arizona. The computations factored in traffic flows under different freeway scenarios depicting different forms of multi-modal travel that would be reasonable for the SR 51 freeway. Five options were compared: (1) high-occupancy/toll (HOT) lanes, (2) adding a fourth general purpose (GP) lane, (3) HOV lane with non-exclusive bus rapid transit (BRT), (4) exclusive BRT, and (5) light rail transit (LRT). The results, ranked from most cost-effective to least cost-effective, are as follows (Note: the range is due to whether costs are spread over all traffic or only peak-period traffic): HOT Lane ($0.012 to $0.027 per person-mile); Fourth GP Lane ($0.019 to $0.042 per person-mile); HOV (w/BRT) Lane ($0.026 to $0.057 per person-mile) (existing condition); Exclusive BRT Lane ($0.066 to $0.147 per person-mile); Light Rail Transit ($0.161 to $0.358 per person-mile)
