ECONOMIC MODEL FOR THE MAINTENANCE OF TRAFFIC SIGNALS

THE PURPOSE OF THIS INVESTIGATION WAS TO DEVELOP A COMPREHENSIVE TRAFFIC SIGNAL AND FLASHER MAINTENANCE PROGRAM, USING SYSTEMS ANALYSIS TECHNIQUES, THAT WAS BOTH ECONOMICAL AND PRACTICAL FOR THE CRAWFORDSVILLE MAINTENANCE DISTRICT IN INDIANA. ALL PHASES OF THE CORRECTIVE AND PREVENTIVE MAINTENANCE OPERATIONS WERE ANALYZED TO DETERMINE THE OPTIMAL MAINTENANCE PROGRAM. THE OPTIMUM LAMP REPLACEMENT PROGRAM, INVOLVING THE DETERMINATION OF THE PROPER TIME DURATION FOR THE MOST ECONOMIC GROUP LAMP REPLACEMENTS, WAS OBTAINED FOR ACTUAL CONDITIONS. THE SHORTEST ROUTES FOR PREVENTIVE OPERATIONS WERE ASCERTAINED FOR SEVERAL MAINTENANCE ALTERNATIVES, AND THE MOST ECONOMIC OPTION WAS REVEALED. IN ADDITION, THE STAFF NECESSARY FOR EFFECTIVE MAINTENANCE OF TRAFFIC SIGNALS AND FLASHERS WAS SPECIFIED FOR THIS STATE HIGHWAY DISTRICT. PREVENTIVE MAINTENANCE IS ADVISABLE FOR TRAFFIC SIGNALS AND FLASHERS BECAUSE IT AFFORDS ECONOMIC ADVANTAGES AND REDUCES THE PROBABILITY OF FAILURE, THEREBY IMPROVING TRAFFIC SAFETY. THE PROCEDURES DEVELOPED IN THIS ANALYSIS CAN BE APPLIED TO ANY MAINTENANCE ORGANIZATION THAT HAS RESPONSIBILITY FOR TRAFFIC SIGNALS AND FLASHERS. /AUTHOR/
