Korea is topographically and meteorologically prone to natural disasters. In addition to extraordinary weather, localized heavy rain is a irregular occurrence. Highway in Korea are frequently damaged by rain, wind, flood, etc. Recently, slope failures are disastrous when they occur in mountainous area adjoining highways. The accidents associated with slope failures have increased due to rapid u...

Abstract—In the previous airfield construction industry, pavements made of reinforced concrete have been used very rarely; however, the necessity to use this type of pavements in an emergency situations justifies the need reference to this issue. The paper concerns the problem of airfield pavement dimensioning made of reinforced concrete and the evaluation of selected dimensioning methods of re...

Analysis of fatality automobile accident data can be challenging in rural areas where a relatively small number of such accidents occurs on specific sections of highways. Combining crash data from the Fatality Analysis Reporting System (FARS) and highway networks and design specifications from the Oklahoma Department of Transportation (ODOT), this article employs Poisson regression analysis to ...

The initiatives known as the Intelligent Vehicle Highway System (IVHS) of the early 1990's, of the Automated Highway System and the Intelligent Transportation System of the middle 90's, and now USDOT's Intelligent Vehicle Initiative of 1998, have all created a climate for rapid advance in ground vehicle communication and control technology. An industry such as that of aerospace lighting, with i...

This article proves the existence and uniqueness of a weak solution to a scalar conservation law on a bounded domain. A weak formulation of hybrid boundary conditions is needed for the problem to be well posed. The boundary conditions are represented by a hybrid automaton with switches between the modes determined by the direction of characteristics of the system at the boundary. The existence ...

A Ithough the number of traffic accidents each year has been substantially reduced over the past decade, highway crashes continue to be a serious problem in the United States. In 1983 approximately 42,400 persons died in highway crashes, and 2 million suffered nonfatal injuries. The 217. reduction in annual highway fatalities and the 367. reduction in the highway fatality rate (fatalities/lOO m...

Intelligent vehicle platoon driving is a process of flexible control based on the coordination between vehicle and highway in intelligent vehicle-highway system. It can improve the velocities and reduce the spacing between vehicles in the platoon, thus, to improve road capacity and road safety. It is the most important for developing intelligent vehicle-highway system to construct intelligent v...

Highway construction has accelerated urban growth and induced direct and indirect changes to land use. Although many studies have analyzed the relationship between highway construction and local development, relatively less attention has been paid to clarifying the various impacts of highways associated with farmland loss. This paper integrates GIS spatial analysis, remote sensing, buffer analy...

Implementing an asset management system that covers field instrumentation in a process plant environment requires some type of smart device platform. Since most modern field devices provide HART communication capability in addition to the analog process variable, plants may have to weigh approaches employing either traditional or integrated HART I/O as part of the decision to move to an instrum...
