Modeling Frequency of Truck Crashes on Limited-Access Highways Abstract Involvement of large trucks in crashes can cause much damage and serious injuries, due to their large sizes and heavy weights. The purpose of this study was to identify the relationships between large truck crashes and traffic and geometric characteristics on limited access highways. Crash and traffic and geometric-related […]

Factors Contributing to School Bus Crashes Abstract School bus safety is a community concern because parents expect their children to be transported to and from school safely. However, relatively few studies have been devoted to examining the factors contributing to school bus crashes. In this study, a logistic regression model is used to delineate the factors that contribute […]

Network-Based Simulation of Air Pollution Emissions Associated with Truck Operations Abstract Estimating greenhouse gasses (GHGs) and other emissions (especially diesel particulates) is an increasingly important basis for regional policy analysis. According to the EPA (2010a), the transportation sector contributed 27.2% of total GHG emissions in 2008, and 50% of these were from truck operations. This research focuses on […]

A Framework for Determining Highway Truck-Freight Benefits and Economic Impacts Abstract This paper proposes a method for calculating both the direct freight benefits and the larger economic impacts of transportation projects. The identified direct freight benefits included in the methodology are travel time savings, operating cost savings, and environmental impacts. These are estimated using regional travel demand models […]

U.S. and European Freight Railways: The Differences That Matter Abstract This paper examines the differences between the United States (U.S.) and European (EU27) freight railways. The inherent or structural factors influencing the railways modal share will be evaluated. It was found that nearly all of the disparity in modal share can be explained by structural or inherent differences, […]
