Filter by Keyword44 report(s) found with highway safety in the keywords field Alternatives to existing transportation truck escape ramps and crash barriers are examined using arrays of wood, bamboo, and fiberglass structural elements that act as energy absorbers as they deform. The behaviors of each material type are analyzed to determine if they have the necessary potential for... This research compares safety, measured by expected crash frequency and severity, on road segments where design exceptions were approved and constructed to similar road segments where no design exceptions were approved or constructed. Data were collected for design exceptions in Utah in the years 2001... In an attempt to predict these crashes, North Dakota driver licensing data and crash data were used to develop a sample of 20,392 teen drivers age 14 to 17. Within the first year after being licensed, these drivers sustained 317 crashes that resulted in an injury or death. The resulting logistic regression... North Dakota consistently experiences a relatively high level of crashes and injuries on rural roads, considering lane miles and vehicle miles traveled. Approximately 55% of the state's travel, in vehicle-miles, takes place on rural roads. North Dakota fatal crash reports from 2003 to 2007 show that... Given the sparsely distributed crashes across various highway systems, this study designed an empirical Bayes (EB) based sliding window technique within a spatial context. By examining roadway safety spatially, the safety analysts are able to account for high-risk locations completely within longer predefined... Occupant protection is one of the easiest and most inexpensive ways to protect yourself when riding in a motor vehicle. Yet many North Dakota youth, especially rural youth, fail to wear their seat belts, even with a primary seat belt law for children under the age of 18 in the state of North Dakota.... Seating children in the rear of vehicles has been shown to decrease the odds of being fatally injured in a motor vehicle crash by 36% to 40%. Although rear seating is safer, rates of children being front-seated remain high, especially for older children. Few states have enacted legislation regarding... Improving roadway safety is an ongoing priority for transportation agencies. However, addressing safety issues in rural areas is difficult for local governments due to the limited resources available for maintenance and improvement projects. Traffic Safety Evaluations (TSE's) have emerged as an effective... SAFETEA-LU contains language indicating that state department of transportation (DOTs) will be required to address safety on local and rural roads. It is important for state, county, and city officials to cooperate in producing a comprehensive safety plan to improve their statewide safety. This legislation... Highway barriers exist in part to protect life and property from excessive danger as part of normal road usage. Typically, these barriers can be characterized as stiff and passive. In this study, we report on the potential use of highly flexible materials that maintain the effective resistance to load... |
