TRAFFIC SIGNAL SYNCHRONIZATION ON A ONE-WAY STREET

VARIOUS SCHEMES OF TRAFFIC SIGNAL SYNCHRONIZATION ARE CONSIDERED FOR A STREET NETWORK COMPRISED OF A MAIN ONE-WAY STREET WHICH IS INTERSECTED BY ONE-WAY (SIDE) STREETS. TRAFFIC ON THE MAIN STREET APPROACHING THE FIRST INTERSECTION IS ASSUMED STEADY AS ARE THE FLOWS ON ALL SIDE STREETS APPROACHING THE MAIN STREET INTERSECTIONS. TRAFFIC SIGNALS ARE IDEALIZED AS PERFECT OFF-ON SWITCHES AND TRAFFIC IS TREATED AS A VARIABLE-DENSITY FLUID MOVING WITH A CONSTANT VELOCITY ON THE MAIN STREET. TOTAL DELAY AND TOTAL NUMBER OF STOPS ARE EVALUATED FOR SEVERAL TYPES OF SIGNAL SYNCHRONIZATION SCHEMES. SOME OBSERVED CONCLUSIONS ARE: (1) FOR ANY GIVEN COMMON CYCLE TIME, AND GIVEN RED-GREEN SPLITS AT EACH INTERSECTION, THERE IS A CHOICE OF SIGNAL OFFSETS (PHASES) THAT SIMULTANEOUSLY MINIMIZES BOTH THE TOTAL DELAY AND STOPS, BUT IT IS NOT NECESSARILY THAT CHOICE WHICH PRODUCES A THROUGH BAND OF MAXIMUM BANDWIDTH, (2) THERE ARE SIGNAL SETTINGS FOR WHICH SOME SIGNALS OPERATE ON ONE-HALF OR ONE-THIRD THE CYCLE TIME OF OTHER SIGNALS WHICH GIVE A MAIN-STREET DELAY EQUAL TO THAT FOR THE OPTIMUM CYCLE TIME SETTING BUT GIVE LESS DELAY TO THE SIDE STREET, AND (3) SIMILAR MODELS ARE COMMONLY USED TO FIND MAXIMUM THROUGH BANDS FOR TWO-WAY TRAFFIC, BUT IT IS NOT OBVIOUS THAT THIS IS A SUITABLE OBJECTIVE EVEN FOR ONE-WAY STREETS, I. E., IT MAY BE MORE BENEFICIAL TO MINIMIZE EITHER TOTAL DELAY OR NUMBER OF STOPS, OR BOTH. /AUTHOR/
