AN EXPERIMENTAL DESIGN FOR THE EVALUATION OF THE "BLUE STREAK" DEMONSTRATION PROJECT

THREE SOURCES OF PASSENGER DIVERSION ARE REVIEWED BY THE AUTHOR AS MEASURES OF EFFECTIVENESS. THE FIRST CHANGE IS AUTOMOBILE TRAFFIC TO TRANSIT, THE SECOND SOURCE OF DIVERSION WILL BE EXISTING TRANSIT USERS WHO SHIFT TO BLUE STREAK AND THE THIRD WILL BE THE GENERATION OF NEW TRAFFIC BECAUSE OF THE IMPROVED SERVICE TO THE CENTRAL BUSINESS DISTRICT (CBD). THE AUTHOR STATES THAT IF THERE IS A DESIRE TO DETERMINE WHETHER THERE HAS BEEN A SHIFT IN MODAL SPLIT BETWEEN AUTOMOBILES AND TRANSIT, THESE THREE SOURCES OF RIDERSHIP CHANGES MUST BE MEASURED AND PARCELLED OUT. THE TRAVEL TIME SAVINGS OF BOTH CBD-ORIENTED AUTOMOBILE USERS ORIGINATION IN OR ENTERING THE CORRIDOR AND THE CAPTIVE RIDERS OF TRANSIT ARE ALSO STRESSED AS BEING A PERTINENT MEASURE OF EFFECTIVENESS. ROUTING DIFFERENCE IS ESSENTIAL TO OBTAINING TRAVEL TIME SAVINGS AND DEVELOPING A RATIONAL MODAL SPLIT MODEL. THE EVALUATION OF BLUE STREAK AS TO PERSON CAPACITY OF THE RESERVED OFF-RAMP IS DISCUSSED. IT IS FELT THAT IF MEANS AND VARIANCE IN OFF-RAMP PERSON VOLUMES CAN BE DETERMINED, IT WILL BE POSSIBLE TO DETERMINE THE CONDITIONS UNDER WHICH EXCLUSIVE BUS RAMPS ARE WARRANTED. IT IS FURTHER FELT THAT THE EVALUATION OF THE BLUE STREAK SERVICE MUST BE CARRIED OUT LARGELY IN THE CONTEXT OF PERSON MOVEMENT BY TRANSIT IN THE CORRIDOR. FOUR EXPERIMENTS WERE PERFORMED; TWO INVOLVED INTRA-TRANSIT MEASURES, THE OTHER TWO WERE TRANSIT VS. HIGHWAY DIVERSION EXPERIMENTS. BASIC VARIABLES IN EXPERIMENTAL DESIGN ARE PRESENTED AND IT IS CONCLUDED THAT WITH THIS DESIGN, IT SHOULD BE POSSIBLE TO MEASURE THE TOTAL TRANSIT PASSENGER VOLUME WITHIN THE BLUE STREAK CORRIDOR AND CONTROL FOR EXOGENOUS CHANGES IN PASSENGER VOLUME. /UMTA/
