The Theory of Adjustment Applied in Road Data Collecting and Optimum Designing of Road

摘要

In the investigation of China present road state and optimum designing of road, the linear data collection and computing of relevant parameters are very important. Though the methods of collecting data are feasible, but the methods of computing design parameters of road are lacking. This paper discusses that the theory of condition adjustment applies in road data collecting and optimum designing of road. The method goes as follows: after the road line types, mileages, curvatures of two endpoints of the road have been known, considering the constraint conditions on the distances between road and buildings on both sides of the road, we adjust all parameters of line type using the theory of Condition adjustment so that they satisfy a series of objective requirements while considering the condition that the curvatures of road should be continuous. This method has proved its availability by Visual C++ programming finally.
