Abstract

A simplified theory of the motion of heavy vehicles on grades is presented. A set of speed-distance curves computed from the theory, based on values of maximum sustained speeds observed in arizona, is given as the current basis for design of climbing lanes in Texas. Speed-distance curves representing the observed performance of a test vehicle on 11 grades are compared with the corresponding curves developed from the theory. Fair agreement was found, and it was concluded that the simplified theory is accurate enough for use in the design of climbing lanes.
