Urban sprawl costs the American economy more than US$1 trillion annually, according to a new study by the New Climate Economy. These costs include greater spending on infrastructure, public service delivery and transportation. The study finds that Americans living in sprawled communities directly bear an astounding $625 billion in extra costs.

This study evaluates rail transit benefits based on a comprehensive analysis of transportation system performance in major U.S. cities.

This analysis investigates the ability of nonmotorized travel (walking, cycling) to help achieve transportation planning objectives. It indicates that nonmotorized travel provides significant benefits, and that these benefits can increase with cost effective incentives.

This report discusses factors to consider when evaluating transportation economic stimulation strategies. Transportation investments can have large long-term economic, social and environmental impacts. Expanding urban highways tends to stimulate motor vehicle travel and sprawl, exacerbating future transport problems and threatening future economic productivity.

This report describes an evaluation framework for identifying optimal (best overall, taking into account all benefits and costs) transportation emission reduction strategies. Current

This paper provides guidance for implementing Pay-As-You-Drive (PAYD) vehicle insurance, which directly incorporates mileage as a rate factor. It describes PAYD pricing options, discusses PAYD benefits and costs, describes regulatory reforms, evaluates various objections to PAYD, and provides specific recommendations for PAYD implementation. Various data sources indicate that crash costs increase with annual vehicle mileage. As a result, PAYD increases actuarial accuracy (premiums better reflect a vehicle

This paper describes ways to improve LEED (Leadership in Energy and Environmental Design) transportation and parking credits. Typical LEED programs reduce building energy consumption 20-60%. Cost effective mobility and parking management programs often provide similar motor vehicle trip and parking generation reductions, resulting in large economic, social and environmental benefits. However, the current LEED rating system overlooks some of the most effective mobility and parking management strategies.
