State-of-the-art methods for the safe and efficient design of bicycle facilities are based on difficult to collect data and potentially dubious assumptions regarding cyclist behavior. Simulation models could offer a way forward, but existing bicycling models in the academic literature have not...

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...

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...

Combined, aviation and marine transportation are responsible for approximately 5 percent of total greenhouse (GHG) emissions in the United States and 3 percent globally and are among the fastest growing modes in the transportation sector. Controlling the growth in these emissions will be an...

In this paper we seek to document what, if any, divergences exist between how experts and ‘lay’ people conceptualize the energy used in automobiles, motivated by previously-documented divergences in the home energy sector. From a total of 15 interviews with 19 individuals, we...
