THE DEVELOPMENT OF HIGHWAY CROSS SECTION SLOPE ANALYSIS ALGORITHM AND THE APPLICATION USING POSITION AND ATTITUDE DATA OF VEHICLE

抄録

The geometric information are highly required to manage and safety evaluation of the highways. Although the detailed highway drawings provide geometric information, occasionally they include differences compared with the real world highway geometry due to overlay or rehabilitation of highways. Especially cross section slope is often changed since rutting or deformation of pavement. Cross section slope is important element at the road safety aspect because it is related to drainage and the centrifugal force of vehicle. In this paper, the cross section analysis algorithm was developed using the position and attitude data of vehicle. The cross section analysis algorithm includes the slope calculation for normal crown, transition and superelevation section. After developing algorithm, the algorithm was applied to the fields to acquire the cross section information. The algorithm showed a good performance when it has been applied to the fields which have various alignment conditions.
