THE JOURNAL OF TRANSPORT AND LAND USE
In light of the increasing reliance on compact growth as a fundamental strategy for reducing vehicle emissions, it is important to better understand how land use-transportation interactions influence the production of mobile source emissions. To date, research findings have produced mixed conclusions as to whether compact development as a strategy for accommodating urban growth significantly reduces vehicle travel and, by extension, mitigates environmental impacts, particularly in the area of air quality. Using an integrated simulation approach coupled with long-term land development scenarios, we conducted an assessment of the impacts of different long-term primarily residential growth patterns on vehicle travel and pollutant emissions in the eight counties of the San Joaquin Valley region in central California.

Risks and Rewards of Public-Private Partnerships for Highways

Friday, January 6th, 2012

REASON FOUNDATION
Public-Private Partnerships (PPPs) for infrastructure are contracts between public and private entities for the provision of facilities in areas such as power, water, transportation, education and health. Well-written PPP agreements specify the allocation of risk, which should create incentives for the private provider to deliver more efficiently and in a timelier manner than would be the case if the project were undertaken by a state-controlled entity.
