THE VIABILITY OF METHODS OF COMMUNICATING TO AND FROM MOVING VEHICLES DEPENDS ON THE AVAILABILITY OF INEXPENSIVE AND RELIABLE ELECTRONIC COMPONENTS OF ADVANCED PERFORMANCE. IF SUITABLE COMPONENTS ARE AVAILABLE, A VARIETY OF SOPHISTICATED SCHEMES FOR MANAGING PRIVATE, COMMERCIAL, AND PUBLIC TRANSPORT BECOMES FEASIBLE ECONOMICALLY AND TECHNICALLY (IF NOT POLITICALLY); POSSIBILITIES INCLUDE THE TRANSMISSION OF ROUTE OR HAZARD INFORMATION TO VEHICLES, THE EXTRACTION OF DATA FROM VEHICLES (IDENTITY, AXLE LOADING, ETC.), AND TWO-WAY COMMUNICATION FOR PUBLIC-TRANSPORT VEHICLES. THIS PAPER SURVEYS THE ROLES WHICH MAY EXIST IN TRAFFIC MANAGEMENT FOR MODERN SOLID-STATE COMPONENTS SUCH AS ADVANCED SILICON INTEGRATED CIRCUITS, CHARGE-TRANSFER DEVICES, SURFACE-ACOUSTIC-WAVE STRUCTURES, AND MICROWAVE SOURCES. SPECIAL EMPHASIS IS GIVEN TO THE BASIC PROBLEMS OF, FIRSTLY, ESTABLISHING LOCALISED REGIONS FOR PROPAGATION ON A SPACE-DIVISION-MULTIPLEX BASIS AND, SECONDLY, PROVIDING STRUCTURES WHICH GENERATE, STORE, AND DETECT COMPLEX CODES OR MESSAGES.
