INVESTIGATION OF THE SENSITIVITY OF TRANSPORTATION SYSTEMS PERFORMANCE TO CHANGES IN LAND USAGE

THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE EFFECT OF FUTURE LAND USES UPON TWO CASE CITIES, BOSTON AND HOUSTON. TWO NEW PATTERNS OF TRANSPORTATION DEMAND WERE CREATED FOR THE CITIES. THE FIRST PATTERN DEMONSTRATED THE INCREASED SUBURBAN NUCLEATION OF TRIP ACTIVITY; THE OTHER SHOWED AN INCREASED CENTRAL FOCUS OF LAND USE. KEY TRANSPORTATION SYSTEMS WERE TESTED AGAINST THESE DEMANDS IN A LARGE-SCALE COMPUTER SIMULATION, WHICH PRODUCED OUTPUT AND AN ARRAY OF SYSTEM PERFORMANCE MEASURES AS WELL AS USER AND SOCIAL COSTS AND BENEFITS. THE KEY SYSTEMS WERE: (1) FREEWAYS, (2) DUAL- MODE GUIDEWAYS, (3) RAPID RAIL, AND (4) PERSONAL TRANSIT GUIDEWAYS. IT WAS CONCLUDED THAT THE TRANSFER OF A SIGNIFICANT NUMBER OF TRIP ENDS TO SUBURBAN NUCLEI DIMINISHED THE CAPABILITY OF CONVENTIONAL RAPID RAIL AND BUSES TO SERVE THE SUBURBAN COMMUNITIES. THE DEMAND UNSERVED BY PUBLIC TRANSIT SYSTEMS CAUSED AN INCREASE IN THE CONGESTION OF STREETS AND FREEWAYS. ONLY THE CONVENTIONAL RAPID RAIL SYSTEM IN BOSTON SHOWED ANY SIGNIFICANT IMPROVEMENT IN PUBLIC TRANSIT AS A RESULT OF AN INCREASE IN THE CENTRAL FOCUS OF TRIP ACTIVITY. THIS CAN BE ATTRIBUTED TO THE INCREASED LOCALIZATION OF CENTRAL BUSINESS DISTRICT STREET CONGESTION SUPERIMPOSED ON AN ALREADY SLOW TRANSPORTATION SYSTEM. THE CHANGES IN THE PERFORMANCE MEASURES INDUCED BY THE INCREASED CENTRAL FOCUS WERE QUITE SMALL, AND TENDED TO BE UNIFORM FOR ALL FOUR KEY SYSTEMS. /UMTA/
