EVALUATION OF SMALL CITY TRAFFIC SIGNAL NETWORK

THE PURPOSE OF THIS RESEARCH WAS TO DETERMINE THE ADVANTAGES RESULTING FROM THE INSTALLATION OF A COORDINATED TRAFFIC SIGNAL CONTROL SYSTEM IN THE CBD AREA OF LAFAYETTE, INDIANA. A BEFORE AND AFTER STUDY WAS PERFORMED AS A MEANS OF EVALUATING THE COORDINATED SIGNAL SYSTEM, AND THE SYSTEM WAS COMPARED WITH LESS COSTLY COORDINATED AND UNCOORDINATED PRE-TIMED SYSTEMS. THE METHODS OF DATA COLLECTION WERE DESCRIBED. AN ANALYSIS WAS PERFORMED USING THE DATA COLLECTED TO DETERMINE WHICH SYSTEM OPERATED MOST EFFICIENTLY AT DIFFERENT VOLUME LEVELS. FINALLY BENEFITS REALIZED BY THE FLEXIBLE SYSTEM IN MONETARY TERMS WERE DETERMINED.
