Collision risk identification and prediction is an effective means to prevent truck accidents. However, most existing studies focus only on highways, not two-lane rural highways. To predict collision probabilities identify high-risk scenes this study first calculated time post-encroachment using high-precision trajectory data combined them with extreme value theory the probability. Subsequently...

Introduction . Road safety is one of the state targets. One indicators road traffic accidents in programs number accident-prone section. Reducing their will lead to a significant increase level security. This due fact that large accidents, deaths and injuries are concentrated these sections. Therefore, task determining factors formation accidentprone section relevant. Materials methods The stud...

O n September 16, 1999, Hurricane Floyd caused widespread flooding through a largely rural area of North Carolina. More than 40 of 100 counties experienced some flooding (Fig 1); the most severe was in the eastern third of the state. Interstate highways and divided 4-lane US highways, as well as hundreds of state highways and local roads, were closed at multiple sites because of flooding or was...

The need for cooperation in the planning of metropolitan trans­ portation facilities has taken on added significance as a result of the Interstate Road Program with its emphasis on arterial improvement in urban areas. A meeting to discuss this problem more fully was held in October 1958 at Syracuse University. This meeting, the National Conference on Highways and Urban Redevelopment (more commo...

Operational speed is an index that represents drivers’ speeding behaviors and shows the comfort and safety levels they experience. Many models had been proposed to predict operational speed in tangent and curve segments of highways. Most of these works had used geometric, with few of them conducted using roadside variables to predict operational speed. Also, the operational speed study in multi...

example, which ranked second highest in terms of per capita income, grants amounted to $46.51 per capita compared with $18.38 for the continental United States; 50 percent of the total grants to the State went for highway construction. Similarly, in the middle-income group, Wyoming received $34.87 per capita in grants, and 48 percent of all grants was for highways. New Mexico, among the low-inc...
