EXCEPT FOR BULK TRAFFIC, GOODS MOVEMENT IN URBAN AREAS IS DOMINATED BY THE MOTOR TRUCK, AND THERE IS LITTLE PROSPECT IN THE FORESEEABLE FUTURE OF ANY MAJOR TECHNOLOGICAL CHANGE THAT WOULD REDUCE THE DOMINANCE OF THE FREEWHEELING VEHICLE ON THE STREETS AND HIGHWAYS. THE FLEXIBILITY OF THE TRUCK IN ORIGINATING AND TERMINATING MOVEMENTS IS COMBINED WITH THE ECONOMIES OF SCALE OF OTHER MODES, WHETHER LARGE TRUCK UNITS ON THE HIGHWAYS, RAILROAD CARS, SHIPS, BARGES, OR AIRPLANES, FOR VIRTUALLY ALL INTERCITY AND INTERREGIONAL MOVEMENTS OF GENERAL FREIGHT. IT HAS FREED MANY INDUSTRIAL AND COMMERCIAL ESTABLISHMENTS FROM THE NECESSITY OF LOCATING ALONG RAILROAD LINES, AND HAS BEEN A MAJOR CONTRIBUTOR, ALONG WITH THE AUTOMOBILE, TO THE DECONCENTRATION OF BOTH RESIDENCE AND BUSINESS. URBAN DENSITY PROFILES--THE GRADATIONS FROM CITY CENTER TO PERIPHERY--HAVE LESS STEEP GRADIENTS, AND THE ORIGINS AND DESTINATIONS OF FREIGHT MOVEMENT HAVE TENDED TO BECOME MORE DISPERSED THAN DURING EARLIER PERIODS WHEN RAIL TRANSPORTATION WAS DOMINANT. THE EMERGING CTY IS INCREASINGLY A MULTINODAL ONE. EVEN THOUGH THE CENTRAL CORE MAY CONTINUE TO BE THE LARGEST IN EACH OF THE RESPECTIVE METROPOLITAN AREAS, ITS RELATIVE IMPORTANCE WILL CONTINUE TO BE REDUCED, WITH MANY OF ITS FUNCTONS TAKING PLACE IN THE NEWER INDUSTRIAL AND COMMERICAL NODES. TRANSFER FACILITIES AT INTERMODAL TERMINALS CONSTITUTE NEW FOCUSES OF URBAN ACTIVITY AND NEW CENTERS FOR THE EMERGING HIGHWAY NETWORKS. SUCH FACILITIES INCLUDE TRUCK TRANSFER STATIONS, RAILROAD AND FORWARDING COMPANY PIGGYBACK AND TRAILER TRANSFER FACILITIES, AIR CARGO TERMINALS, PORT TERMINALS, AND BULK STORAGE FACILITIES FOR FUELS. THE COMPREHENSIVE TRANSPORTATION- LAND USE STUDIES, DEVELOPED FROM THE EARLIER ORIGIN- DESTINATION STUDIES AND COMBINED WITH REAL PROPERTY INVENTORIES AS ESSENTIAL PARTS OF THE URBAN AND METROPOLITAN PLANNING PROCESS, HAVE LAGGED IN NOT GIVING AS GREAT EMPHASIS TO DEVELOPMENT OF MODELS OF FREIGHT MOVEMENT AS THEY HAVE TO PASSENGER MOVEMENT. THE PLANNING OF FUTURE RELATIONSHIPS AMONG SYSTEMS OF FREIGHT TRANSPORTATION AND THE LOCATION OF THE VARIOUS LAND USES MUST, FURTHERMORE, INVOLVE CONSIDERATIONS OF ALTERNATIVE PATTERNS OF MOVEMENT IN ORDER TO MINIMIZE THE TOTAL VOLUME OF TON-MILES GENERATED, JUST AS THE MORE-OR-LESS STANDARDIZED TRANSPORTATION-LAND USE STUDIES THAT ARE NOW MAJOR PARTS OF THE PLANNING PROCESS CONSIDER OPTIMIZATION OF THE NETWORKS OF ROUTES FOR PASSENGER FLOWS. /AUTHOR/
