Book Description

The use of large trucks has steadily increased since the passage of the Surface Transportation Assistance Act to the point where they now account for over 50% of vehicle traffic on some highways in Virginia. Projections now forecast that large-truck travel will grow at twice the rate of personal vehicle travel in the near future. Although several studies have been conducted to determine the effects of large trucks on safety on multilane primary and interstate highway systems, the effects on two-lane secondary roads have been largely ignored. This study identified the causal factors and predominant types of large-truck crashes on two-lane secondary roads in Virginia and compared the large-truck crash rates for two-lane secondary roads and two-lane primary roads. The study also identified advanced technologies associated with intelligent transportation systems (ITS) that can be used to minimize the causal factors of large-truck crashes on these roads. The results showed that large-truck crash rates are significantly higher on two-lane secondary roads than on two-lane primary roads, with the predominant types of crashes being angle, rear end, sideswipe same direction, and sideswipe opposite direction. The study identified several ITS technologies that can be used to mitigate the predominant causal factors and recommends a pilot study to test the effectiveness of one such system.

Book Description

"Why GAO Did This StudyVehicles carrying objects that are not properly secured pose a safety risk on our nation's roadways. Debris that falls from a vehicle can collide with other vehicles or pedestrians, causing serious injuries or fatalities. According to data collected by NHTSA, there were about 440 fatalities caused by roadway debris in 2010. However, the exact number of incidents resulting from vehicles carrying unsecured loads is unknown.Congress, through the Conference Report for the Consolidated and Further Continuing Appropriations Act, (2012), directed NHTSA to improve its data on unsecured-load incidents and directed GAO to report on state laws and related exemptions, and punitive measures regarding unsecured loads on non-commercial vehicles, such as cars and light trucks used for non-commercial purposes. This report examines NHTSA's data collection efforts as well as states' laws related to unsecured loads. GAO reviewed NHTSA documents and interviewed officials from NHTSA, as well as representatives of highway safety associations and state police agencies. GAO also conducted a survey of all 50 states and the District of Columbia, with a response rate of 100 percent, and researched the laws, punitive measures, and education efforts in each state.GAO provided a draft of this report to NHTSA for review and comment. NHTSA provided technical comments that were incorporated, as appropriate"
