A RESPONSE SURFACE APPROACH TO IMPROVING TRAFFIC SIGNAL SETTINGS IN A STREET NETWORK

THE PROBLEM OF DETERMINING THE SETTINGS FOR THE CONTROLLABLE PARAMETERS OF A NUMBER OF PRETIMED TRAFFIC SIGNALS LOCATED THROUGHOUT A GENERAL STREET NETWORK IS CONSIDERED. A TECHNIQUE BASED ON RESPONSE SURFACE METHODOLOGY IS PRESENTED THAT COMBINES A SEARCH PROCEDURE AND A TIME-ORIENTED SIMULATION MODEL OF THE SYSTEM UNDER STUDY. ANY MEASURABLE OBJECTIVE FUNCTION MAY BE OPTIMIZED OR IMPROVED UTILIZING THIS METHODOLOGY. AN EXAMPLE SITUATION IS PRESENTED IN WHICH A LINEAR COMBINATION OF VEHICLE STOPS AND DELAYS FOR A SIX-SIGNAL NETWORK IS LOCALLY MINIMIZED FOR VARIOUS SETS OF CONTROLLABLE PARAMETERS AND FOR THREE DIFFERENT TIME PERIODS. IN ALL CASES THE TECHNIQUE GENERATED PARAMETER SETTINGS THAT WERE SIGNIFICANTLY IMPROVED WITH RESPECT TO THE INITIAL OPERATING CONDITIONS FOR THE SIX SIGNALS. STATISTICAL VERIFICATION OF THE RESULT IS GIVEN. /AUTHOR/
