System Approach To Transportation 700183

The systems approach to a problem defines the goal and constraints on the problem and works backward to find the requirements these imply for the subsystems and lesser components.This paper deals with a California experience in socially relevant system engineering and with the system approach to transportation. For the latter, one must determine needs, examine alternatives, determine trade-offs, rank alternatives on a cost-effective basis, and iterate by restudying the chosen system on a deeper and narrower basis.
