SEMI-ACTUATED SIGNAL STUDY

THE SEMI-ACTUATED SIGNAL STUDY IS A PORTION OF A LARGER STUDY BEING CONDUCTED TO IMPROVE THE EFFECTIVENESS OF TRAFFIC SIGNAL SYSTEMS. THE SPECIFIC AIM OF THE SEMI-ACTUATED PORTION WAS TO TEST THE EFFECTIVENESS OF THE USE OF SEMI-ACTUATED, AS COMPARED TO FIXED TIME SIGNAL CONTROLLERS AT MINOR SIGNALIZED INTERSECTIONS ALONG PROGRESSIVELY TIMED ARTERIAL STREETS. THE REPORT DESCRIBES THE DESIGN, DATA COLLECTION AND ANALYTICAL PROCEDURES. FOR THE SITES INVESTIGATED, THE REPORT CONCLUDES THAT FIXED-TIME SIGNAL CONTROL AT MINOR INTERSECTION PROVIDES LESS STOPPED-TIME DELAY ON A SYSTEM BASIS THAT EITHER SEMI- ACTUATED PRESENCE DETECTION OF SEMIACTUATED PULSE DETECTION. /FHWA/
