PANATRAC 300 and 400, recently developed computerized area traffic control systems, are described. The PANATRAC 400 can control up to 1200 intersections in a large city by a hierarchy computer system. The PANATRAC 300 is designed to control up to 300 intersections in a relatively small city by a single-stage computer system. The essential part, such as CPUs and communication control units in both systems, is doubled in its number for preventing failure of the system; when one computer fails, another is switched in one second to perform intersection control. The communication control unit, being capable of 512 intersections, is simplified, so that it can be installed in only two 19 seconds racks (80 seconds high). The PANATRAC 300 uses minicomputer MACC-6500, which consists of a CPU, conventional peripheral machines, a communication control unit and a PIO. The PIO controls a display system that shows traffic information on a large city map board.
