Economic Implications of Transportation Investments and Land Development Patterns

摘要

The report presents four papers that can be used for evaluating the private,government, and social implications of alternative transportation and land use decisions. The first paper, Business Location in Today's Economy, explores the relationship between changing business operating conditions and firm location needs. The implications of these changes to broader planning and policy goals are also discussed. The second paper, The Costs of Alternative Land Use Patterns, presents an analytical framework and a prototype model for estimating the full costs of alternative land use patterns. The paper also presents results from application of the full cost model to Portland, Oregon. The third paper, Using STEAM for Benefit-Cost Analysis of Transportation Alternatives, discusses application of FHWA's recently developed STEAM model for multi-modal transportation evaluation. STEAM utilizes speed relationships that account for the effects of queuing under recurring congestion as well as incidents. The fourth paper, Improved Speed Estimation Procedures for Use in STEAM and in Air Quality Planning, presents the speed relationships and methodology used to develop them.
