Skid Characteristics of Pavement Surfaces in Indiana
In 1953, drivers in the United States became involved in 31,450 fatal and 1,302,000 non-fatal accidents. Many of these accidents were primarily the fault of the drivers involved, but a great number might have been minimized or prevented by safer highways. Although many factors are involved in the building of safety into highways, one of the more important items is the resistance of pavement sur...
متن کاملLimitations of Using Skid Number in Accident Analysis and Pavement Management
Pavement frictional characteristics are commonly determined by conducting skid tests in accordance with ASTM Standard E274. The results of these tests [skid number (SN)] are used in ranking roads to establish construction priorities and to estimate tirepavement friction in accident analysis. The role of SN in these two applications is addressed. There are serious limitations constraining the us...
متن کاملDetermining Curve Number and Estimating Runoff Yield In HESARAK Catchment
The process of precipitation – runoff of each basin, is influenced by hydrologic, geomorphology conditions, geological formation and vegetation. There are different methods in drainage basins. One way to estimate the runoff height is Curve Number (CN) method. That reperesents the hydrological behavior of basin. data were collected for statistics of climate and then topographic map of 1: 25000 a...
متن کاملEvaluating Safety Effects of Ramp Density and Horizontal Curve for Freeways Using Texas Data
Increased emphasis has been placed on improving the explicit role of highway safety in making decisions on highway planning, design, and operations. This can be achieved by quantifying the safety effects of geometric design elements for various highway facilities. While great attention has been directed primarily on rural two-lane highways and to a lesser degree, on urban arterials and rural mu...
