URBAN LAYOUT AND TRANSPORT SYSTEMS: A THEORETICAL/PRACTICAL STUDY

THE COMPLEXITY OF THE CITY HAS LONG DEMANDED AN URBAN THEORY WHICH WOULD BE OF PRACTICAL VALUE IN UNDERSTANDING THE CITY AND DETERMINING AIMS FOR IMPROVEMENT. THE OBJECTIVE WAS TO MEET PEOPLES' WANTS AT MINIMUM TOTAL COSTS. THE STUDY FELL INTO FIVE SECTIONS: (1) THE SHAPE OF NEW TOWNS IN TWO DIMENSIONS. VARIOUS LAYOUTS WERE COMPARED FOR MINIMUM TOTAL TRANSPORT COSTS. THE BEST LAYOUT WAS FOUND TO BE CIRCULAR, BUT WAS NOT CRITICAL PROVIDED THAT EXTREME SHAPES WERE AVOIDED. (2) THE LAYOUT OF ESTABLISHMENTS IN A NEW TOWN. THE BEST LAYOUT WAS FOUND TO BE INDETERMINATE, BUT WOULD PROBABLY BE CLOSELY APPROXIMATED TO BY A BASIC LAYOUT OF A CENTER PLUS FOUR SUBCENTERS. (3) THE MAIN ROAD NETWORK OF NEW TOWNS - VARIOUS NETWORKS WERE COMPARED TRAVEL PATTERNS, THE BEST GENERAL NETWORK PROVING TO BE A RADIAL/RING OR BOX, WHICH MOST OF THE OTHER POSSIBLE FORMS, E. G. THE SQUARE GRID, WOULD TEND TO RESEMBLE IN PRACTICE. (4) PUBLIC TRANSPORT SYSTEMS AND URBAN LAYOUT - THE KEY TO THE BEST BUS SYSTEM WAS FOUND TO BE THE EXPANSION OF ROUTES, AND OF BUSES OVER THEM, UNTIL TOTAL WALKING, WAITING AND BUS COSTS PER DAY WERE EQUAL. THE BEST SYSTEM FOR CENTRAL JOURNEYS WAS FOUND TO BE RADIAL, WHICH COULD ALSO CATER FOR DISPERSED JOURNEYS AS WELL AS DISPERSED SYSTEMS. (5) OVERALL CONCLUSIONS AND APPLICATION TO EXISTING TOWNS - THE RESULTS WERE USED TO CONSIDER IN WHICH DIRECTION RADIAL, GRID AND LINEAR TYPE CITIES COULD BEST BE CHANGED IN THE LONG RUN. /RATAOC/
