Future air pollution emissions in the year 2030 were estimated for the San Joaquin Valley (SJV) in central California using a combined system of land use, mobile, off-road, stationary, area, and biogenic emissions models. Four scenarios were developed that use different assumptions about the...

Diesel-electric locomotives used by U.S. freight railroads are relatively low emitters of criteria air pollutants and greenhouse gases when compared to competing modes; however, the continuous growth in goods movement is cause for concern as locomotive emissions may grow. Railroads only account...

Emission inventory models are a key input to regional air quality plans, called State Implementation Plans (SIPs) in the US. These plans frequently include emissions caps, or “budgets,†to which transportation system emissions must be compared. When emissions models and vehicle...

With the passage of the Global Warming Solutions Act of 2006 (AB32), California has begun an ambitious journey to reduce in-state GHG emissions to 1990 levels by 2020. Under the direction of executive order S-20-06, a mandated Market Advisory Committee (MAC) charged with studying market-based...

This literature review has been prepared to synthesize and assess previous small-scale economic evaluations of telecommuting. These small-scale studies can be categorized as telecommuting pilot projects that take into account telecommuter and employer costs and benefits. (The reader is referred...

This report evaluates the costs and benefits of home-based telecommuting. Combining empirical data from the literature with a Monte Carlo simulation technique, a distribution of cost-benefit ratios is produced from three perspectives: the employer, the telecommuter, and the public sector.......
