Abstract: The discrepancy between transit's large share of local transportation resources and its generally low share of local trips has raised questions about the use of scarce transportation funds for this purpose. We use a regional transport model consistent with utility theory and calibrated for the Washington, DC metropolitan area to estimate the travel benefits of the local transit system to transit users and the congestion-reduction benefits to motorists. We find that (i) rail transit generates congestion-reduction benefits that exceed rail subsidies; (ii) the combined benefits of rail and bus transit easily exceed local transit subsidies generally; (iii) the lowest income group received a disproportionately low share of the transit benefits, both in absolute terms and as a share of total income; and (iv) for practical purposes, the scale of the current system is about optimal.
Keywords: Transit; Transit subsidies; Traffic congestion

Environmental Valuation & Cost Benefit News covers legal, academic, and regulatory developments pertaining to the valuation of environmental amenities and disamenities, such as clean air, trees, parks, congestion, and noise. We apprise the reader about ways in which costs and benefits are measured, and the results of empirical studies. We hope that this information will allow public and private organizations to comprehend the risks and benefits of various actions, help disputants to resolve conflicts equitably and efficiently, and improve the quality of public policies. We will only discuss issues related to the empirical quantification of private and social costs and benefits and damages, and summarize information from daily newspapers, academic journals, legal publications, court decisions, professional newsletters commissioned studies, and on-line services. This newsletter is dedicated to the principal that all policies place values upon life, liberty, and the pursuit of happiness. We believe that more information, explicit specification of assumptions, and rigorous analysis can help our society to better meet these ends. This site will increasingly serve, in conjunction with others, as a valuation database. We will include a wide range of studies, including non-environmental reports, because omission of a factor effectively values it at zero, and biases decisions. Heavy traffic has caused several site crashes. We are attempting to correct these problems. Apologies for any inconvenience.
