설계 일관성 평가 모형의 고찰과 개선방안 연구

It's essential to meet the expectations of drivers through reasonable road design, which makes the drivers to recognize the conditions of road sufficiently. In this case, we could say that because the roads are consistently designed, drivers can make a safe and comfortable drive. There are so many studies about the alignment design consistency methods which are previously mentioned. In this study, Firstly we categorize the studies which are concerned with the estimation of the alignment design consistency methods and then apply the method which fits for the actual condition into the practice. And we'll make a realistic method by using the data which are collected from the National Road. The developed model in this study is the predicting model including speed(V l ) as the variable on the upper stream 100m of the curve. This model was developed which divided to two cases in the all directions of two lanes ; One case is the R≤200m and another case is the R＞200m. In the section of the R≤200m, this case was influenced on the road alignment(R) and (V l ) and another section was found that is affected to the speed(V l ) on the upper stream 100m rather than the effect of road alignment(R). In the case of all directions of four lanes, however, this study is predicted divided to two sections on the 400m of R, these section have more influenced to (V l ) than the road alignment factors. This result of the four lanes was represented to different result with the two lanes. This study will further need development of the predicting model with the higher confidence through collecting data with more the exact data, the various road alignment data and speed of the several sections on the upper stream on the curve.
