Abstract
Two-Lane Highway of Korea is important, Because it has the largeest portion of all roads of Korea. But it has only one lane for one direction. So, If Delays are happened by low-speed vehicles, high-speed vehicles should over-take through the other side of the road. This over-takings can generate the high possibility of traffic accidents and the severity of traffic accidents by over-takings is very high. Because it generates a head-on collision. But the level of Service that indicates the operation states of Two-Lane Highway is defined as a conception that explains the operation conditions of traffic safety etc. Whencalculating the Level of service. It is considered by only delays. So, in this paper, first, this author wants to present the calculation of delay-time by Total-Delay Rate. Second, by multiplying this delay-time by the costs of delays wants to present the method of calulates the total delay costs. Third, to consider the traffic accidents, After predicting the number of traffic accidents, As multipling this by the average of costs of traffic accidents. want to present the method to calculate Total traffic accidents costs. Forth, present the operation costs.
