Abstract : This study subdivided the technology of transportation into the following five categories: (1) vehicles; (2) propulsion systems; (3) rightof-way and allied structures; (4) storage and maintenance facilities; and (5) control systems. The general approach is to consider these five categories as the physical building blocks of any transportation system, to evaluate and describe each component in terms of extant and developing technological and economic pressures, to reshape each component into the form it will probably have in the foreseeable future, and to reconstruct possible transportation systems of the future by rebuilding with the blocks which evolve from the foregoing procedures. The performance of land transportation systems and the derived equations of motion are based on an analysis of vehicle-propulsion system combinations. Equations of motion for vehicle-propulsion system combinations are developed by considering the movement of a land transportation vehicle as linear motion of a rigid body. The relationship between automation and effective speed can be evaluated. A design engineer can use the derived equations to estimate acceleration characteristics and maximum speed for a given vehicle-propulsion system combination. (Author)
