Book Description
Roadway safety is an integral part of a functioning infrastructure. Many types of vehicles use the highway system for a variety of purposes, and each affects the roadways differently. Aside from commuter traffic and leisurely travel, a major use of the highway system is the transport of goods. These goods are typically transferred in large trucks. As supply and demand grows, the amount of trucks on the roadways needed to transport goods increases. The United States has experienced constant growth in the amount of freight transported by truck in the last few years. While overall national freight growth is constant, localized effects are more varied. Freight traffic may spike in areas based on events such as a new factory, or the discovery of a natural resource. These additions to a localized area can be taxing on the citizens and infrastructure, and the effect that truck traffic has on these areas may be more concentrated. The state of Wyoming has begun to experience a large increase in truck traffic on some of its local and county roads due to an increase in oil and gas production. The primary measure to evaluate the safety of a roadway is the number of crashes. This study addresses the effect that large truck traffic is having on the safety of various road sizes and classifications. For this study, large trucks are defined as vehicles weighing more than 26,000 pounds and the safety is measured by a crash's severity. An investigation on past literature revealed that many studies have been done on the factors involved in and the causation of heavy truck crashes, but none address the causation and effect the truck crashes have on different types of areas. Answers to this question may give transportation engineers guidelines on how to address truck safety in specific types of areas. A descriptive analysis of statewide crash data revealed many different trends in crashes. Most truck crashes occurred on interstates and primary federal highways. When road conditions were not clear, crashes more often occurred when snowy weather and icy roads were present. Heavy trucks were involved in multi-vehicle crashes less often than passenger vehicles. To verify some of the effects from the descriptive analysis, a logistic regression model was used to further explore the results. A localized study was also conducted to acquire better knowledge of the effect that trucks were having on local roads. This crash analysis focused on four counties in Eastern Wyoming and found that where truck traffic volumes have been increasing, so have crash rates in those counties.

Book Description
The purpose of this report is to identify potential improvements in terms of more effective safety and environmental regulation for trucks, backed by better systems of enforcement, and to identify opportunities for greater efficiency and higher productivity. The report is based on a review of literature, consultation among stakeholders, and research and analysis from working group members. It also presents the results of a comprehensive benchmarking study of 39 truck configurations in operation around the world – from typical workhorse vehicles to very high capacity vehicles – and assesses their performance in terms of dynamic stability, productivity and impact on the infrastructure.

Book Description
There are approximately 4,000 fatalities in crashes involving trucks and buses in the United States each year. Though estimates are wide-ranging, possibly 10 to 20 percent of these crashes might have involved fatigued drivers. The stresses associated with their particular jobs (irregular schedules, etc.) and the lifestyle that many truck and bus drivers lead, puts them at substantial risk for insufficient sleep and for developing short- and long-term health problems. Commercial Motor Vehicle Driver Fatigue, Long-Term Health and Highway Safety assesses the state of knowledge about the relationship of such factors as hours of driving, hours on duty, and periods of rest to the fatigue experienced by truck and bus drivers while driving and the implications for the safe operation of their vehicles. This report evaluates the relationship of these factors to drivers' health over the longer term, and identifies improvements in data and research methods that can lead to better understanding in both areas.
