A review of significant activities in the area of computerized school bus routing is conducted. The various factors which contribute to the complexity of transporting students to and from school are first surveyed and, following this, the overall problem is formalized in terms of a system of nodes and links. An analysis of several routing systems is presented, including: 1) manual schemes, 2) punched card systems, 3) systems which are based on models drawn from other fields such as sales or warehouse shipping, 4) computerized systems and 5) randomly generated routing systems. The conclusion is advanced that the computerized systems developed for particular school districts are usually not generalizable to other districts. Since the needs of individual districts vary widely, it is recommended that each develop a computerized system which best fits its local specifications. (PB)
