| Abstract: | Here a set of algorithms are studied. On one plan line, by use of the numeral topography model (NTM), the ground elevation could be obtained. Then by the B-spline method the profile can be fitted out. Based on these elevations, the traction power can be calculated and then the curve of the relation between resultantforce and velocity and travel time can be given by use of these data. The running capacity and the construction cost would be obtained so that we can have all kinds of evaluations about this plan line. |
