EVALUATING ALTERNATIVE STRATEGIES FOR CENTRAL-CITY DISTRIBUTION

CENTRAL-CITY DISTRIBUTION IS AN ESSENTIAL ELEMENT IN THE HIERARCHY OF A REGIONAL TRANSPORTATION NETWORK. IT IS THE TOTAL SYSTEM THAT THE USER VIEWS, AND CONSEQUENTLY BOTH COLLECTION AND DISTRIBUTION SYSTEMS REQUIRE SEPARATE EVALUATION. A CENTRAL-CITY DISTRIBUTOR SYSTEM CAN BE COMPOSED OF PEDESTRIAN WAYS, BUS SYSTEMS ON EXISTING STREETS, OR MECHANIZED LOOPS ON EXCLUSIVE RIGHTS-OF-WAY. THE DISTRIBUTOR SYSTEM TECHNOLOGY IS INFLUENCED BY THE NATURE AND CONFIGURATION OF THE REGIONAL SYSTEM. IF THE REGIONAL SYSTEM PENETRATES THE CORE AREA, THEN BOTH DELIVERY AND DISTRIBUTION MUST BE ACCOMPLISHED WITHIN ONE SET OF CRITERIA. IF TWO OR MORE TECHNOLOGIES ARE CONSIDERED, THEN A GREATER VARIETY OF ALTERNATIVES IS POSSIBLE BECAUSE THE REGIONAL SYSTEM IS FREED OF ITS ROLE AS A CBD DISTRIBUTOR AND THE DISTRIBUTOR SYSTEM IS FREED OF THE RESTRAINTS DICTATED BY THE LOCATION OF THE REGIONAL LINES. THE SELECTION OF ALTERNATIVE STRATEGIES IS BASED ON A VARIETY OF FACTORS INCLUDING FACILITY COST, LEVEL OF SERVICE, ENVIRONMENT, AND COMMUNITY IMPACT. TRAVEL TIME, INCLUDING WAITING, WALKING, STATION DWELL, TRANSFER AND RIDING, IS UTILIZED IN THIS STUDY TO EVALUATE A VARIETY OF SINGLE- TECHNOLOGY AND SMALL-VEHICLE SYSTEMS DEVELOPED FOR THE PITTSBURGH CENTRAL BUSINESS DISTRICT. THE MODEL DEVELOPED CALCULATES ALL APPROPRIATE PATHS BETWEEN EACH CORDON POINT AND THE ZONE CENTROID FOR A CONVENIENCE (MINIMUM TIME) RULE AND FOR AN ACCESSIBILITY (MINIMUM WALK) RULE. /AUTHOR/
