BLUE STREAK BUS RAPID TRANSIT DEMONSTRATION PROJECT -- PHASE I: INTERIM REPORT

THE PURPOSE OF THE REPORT IS TO OUTLINE INITIAL SURVEY DATA AND PROVIDE A PROJECT OVERVIEW FOR LATER COMPARISONS WITH LONG-RANGE RIDERSHIP INFORMATION. THE BLUE STREAK PLANNING PROCESS AND THE ROLES PLAYED BY DIFFERENT PARTICIPANTS ARE DISCUSSED BRIEFLY. THE PHASE I ANALYSIS CONTAINS DATA ON RIDERSHIP, MODAL SPLIT, AND TRAFFIC VOLUME BY TIME OF DAY AFTER COMMENCEMENT OF EXPRESS BUS SERVICE. SURVEY PROCEDURES ARE DISCUSSED IN DETAIL; BASICALLY, DATA WAS COLLECTED AT TWO "SCREENLINE" POINTS ALONG THE ROUTE. THESE WERE TERMINAL BUS STOPS IN THE CENTRAL BUSINESS DISTRICT AND BRIDGE CROSSINGS OVER THE LAKE WASHINGTON SHIP CANAL WHICH RUN PERPENDICULAR TO BLUE STREAK ROUTES. IN ADDITION, THE REPORT COVERS AVERAGE SPEEDS ALONG DIFFERENT SEGMENTS OF THE FREEWAY NETWORK, TRAFFIC VOLUME ON SELECTED DOWNTOWN ACCESS RAMPS, TRAVEL TIME FROM SELECTED TRIP GENERATORS, AN ORIGIN-DESTINATION SURVEY, AND OVERALL RIDERSHIP BROKEN DOWN BY SUCH INDICATORS AS FAMILY INCOME, AUTOMOBILE ACCESSIBILITY, AND BUS-ACCESS MODE. HEADWAYS AMONG BUSES OPERATING ON SELECTED ROUTES ARE ALSO DETERMINED. ALTHOUGH THE DATA GENERATED BY PHASE I WERE COLLECTED PRIMARILY FOR COMPARATIVE PURPOSES AT A LATER DATE, SOME INITIAL CONCLUSIONS ARE ADVANCED. INTERAGENCY COOPERATION AMONG THE VARIOUS TRANSPORTATION DEPARTMENTS SERVING SEATTLE WAS INSTRUMENTAL IN MAKING BLUE STREAK A SUCCESSFUL VENTURE. EARLY RESULTS CLEARLY INDICATE A SIGNIFICANT DIVERSION OF PREVIOUS AUTOMOBILE COMMUTERS TO THE EXPRESS BUS, PRIMARILY DUE TO THE AVAILABILITY OF PARK-AND-RIDE FACILITIES AND THE BUSES EXCLUSIVE USE OF CERTAIN HIGH-DEMAND FREEWAY RAMPS AND LANES. PRELIMINARY ESTIMATES INDICATE THAT AS MUCH AS 30% OF OVERALL RIDERSHIP WAS NEWLY GENERATED. /UMTA/
