CRITERIA FOR TRANSPORTATION PLANNING

A METROPOLITAN AREA IS DEFINED AS A COMMON LABOR AND HOUSING MARKET WHICH EXTENDS OVER A TIME DISTANCE OF 45 TO 60 MINUTES (WHICH) PRESENTLY MEANS A RADIUS OF 20 TO 40 MILES). IT MAY BE SAID THAT THE TRAFFIC PROBLEM EXISTS NOT BECAUSE MEANS OF TRANSPORTATION ARE BAD BUT BECAUSE THEY ARE GOOD, I.E., ALTHOUGH GROWTH OF URBAN AREAS HAS BEEN GREAT, AVERAGE JOURNEY TIME TO WORK HAS BEEN FAIRLY CONSTANT. IT APPEARS THAT BENEFITS OF IMPROVED TRANSPORTATION HAS BEEN IN TERMS OF MORE SPACE AND GREATER CHOICE NOT IN TERMS OF LESS TIME. ASSUMING MOBILITY IS TO BE THE GOAL OF TRANSPORTATION, THE CRITERION FOR PLANNING MUST BE THE MINIMIZATION OF THE FRICTION OF SPACE IN TERMS OF TIME, MONEY AND INCONVENIENCE. FOR "PERSONS" TRANSPORTATION, (AS OPPOSED TO GOODS) TIME- MONEY EQUIVALENTS HAVE TO BE DEVELOPED; HOW MUCH MONEY ARE PEOPLE PREPARED TO SPEND TO SAVE TIME AND IS THE SAVING OF 30 SECONDS BY 60 PEOPLE THE SAME AS SAVING 1/2 HOUR BY ONE PERSON? ALSO, THE QUANTIFICATION OF INCONVENIENCES INTO TERMS OF TIME AND MONEY IS DIFFICULT; HOW MUCH ARE PEOPLE PREPARED TO SPEND TO AVOID THEM? IN ADDITION TO BENEFITS AND COSTS OF THE TRAVELLING PERSON, "MALEFITS" (OPPOSITE OF BENEFITS) MUST BE CONSIDERED SUCH AS TIME LOSS OF PEDESTRIAN MOVEMENT BECAUSE OF VEHICULAR IMPEDIMENTS, AND ENVIRONMENTAL EFFECTS OF DANGER, NOISE, ESTHETIC DISPLEASURE AND AIR POLLUTION. THESE "MALEFITS" REPRESENT SOCIAL COSTS THAT MUST BE BORNE BY THE BUYER OR THE TRANSPORTATION USER. THE GOAL OF REDUCING FRICTION OF SPACE FOR THE MOVING PERSON CALLS FOR A SYSTEMATIC ANALYSIS OF THE SOURCES OF FRICTION AND THE COST OF THEIR ELIMINATION. HERE THE COMPARISON OF COSTS AND BENEFITS ARE TOO FREQUENTLY FRAMED IN AN "EITHER-OR" SOLUTION. IT IS POSSIBLE THAT AN ANALYSIS MAY SHOW THAT 80% OF THE FRICTION CAN BE ELIMINATED AT 50% OF THE COST OF A 100% SOLUTION. COST ESTIMATES MUST INCLUDE CONSIDERATION OF THE SOCIAL COSTS OF PRIVATE TRANSPORTATION, COSTS OF PUBLIC TRANSIT OPERATION (BOTH EXPRESS AND LOCAL), TIME COSTS OF PASSENGER TRANSFERS OR WALKS TO STATIONS, AND/OR HIGH CAPITAL INVESTMENT FOR NEW PUBLIC TRANSIT SYSTEMS. THE DISCUSSION EMPHASIZES THE PROBLEMS OF TRANSPORTATION RATHER THAN TECHNICAL MEANS OF SOLUTION AND THAT SYSTEMS RESEARCH SHOULD PRECEDE TECHNOLOGICAL RESEARCH, ALTHOUGH BOTH MAY HAVE TO PROCEED SIMULTANEOUSLY.
