A COMPUTER CONTROLS TRAFFIC SIGNALS

FIFTEEN YEARS HAVE PASSED SINCE THE CONCEPT OF CONTROLLING TRAFFIC SIGNALS BY MEANS OF A DIGITAL COMPUTER WAS FIRST PROPOSED. THIS TECHNIQUE ORIGINATED IN METROPOLITAN TORONTO AND IS NOW IN USE IN MORE THAN A DOZEN OTHER MAJOR CITIES THROUGHOUT THE WORLD. PREVIOUS PAPERS HAVE DEALT AT LENGTH WITH THE HARDWARE AND WITH EARLY EXPERIMENTAL RESULTS. THIS PAPER EMPHASIZES TORONTO'S EXPERIENCE OVER THE LAST FIFTEEN YEARS-RECOUNTING BRIEFLY THE DEVELOPMENT OF EQUIPMENT; SUMMARIZING THE CONCEPTS AND THE INITIAL PILOT STUDY AND ITS EARLY RESULTS; AND CONCENTRATING MAINLY ON THE CONTROL LOGIC BEING USED AND THE EVALUATION PROGRAMS WHICH HAVE BEEN DEVELOPED. /AUTHOR/
