PLANNING SPECIAL TRANSPORTATION SERVICES

READILY AVAILABLE DATA, SUCH AS REGULAR CENSUS DATA REGARDING INCOME AND OCCUPATIONAL STATUS OR SPECIAL CENSUS DATA REGARDING TRAVEL CHARACTERISTICS AND AUTOMOBILE OWNERSHIP CAN BE USEFUL IN TWO WAYS. THE FIRST IS TO IDENTIFY A REGION OF HOMEGENEITY, OR SIMILAR CHARACTERISTICS, IN WHICH PATTERNS OF TOTAL TRAVEL BEHAVIOR ARE SOMEWHAT PREDICTABLE. THE SECOND IS TO USE THE DATA TO DEVELOP CAUSATIVE RELATIONSHIPS BETWEEN POPULATION CHARACTERISTICS AND TRAVEL. IN A TIME WHEN WE ARE PLANNING FOR GROUPS THAT ARE BECOMING INCREASINGLY ARTICULATE IN DEFINING THEIR GOALS, WE CAN NO LONGER BE SEDUCED INTO THINKING THAT DATA ALONE WILL SOLVE ALL PLANNING PROBLEMS. HOWEVER, IT IS POSSIBLE THROUGH PROPER STUDIES OF TRIP-DETERMINING PARAMETERS TO ISOLATE AREAS OF PARTICULAR INTEREST FOR SPECIAL (MICRO) STUDY. CONTOUR MAPS DEFINING RINGS OF CHARACTERISTIC INCOME, LAND VALUE, HOUSING RENTALS, AUTOMOBILE OWNERSHIP, TRANSIT HABITS, PROFESSIONAL STATUS, ETC., CAN BE COMBINED WITH TRIP-MAKING CURVES TO SHOW AREAS OF POTENTIAL NEGLECT IN LARGE-SCALE PLANNING. ISOLATION OF THESE AREAS FOR INTENSE STUDY, COUPLED WITH GATHERING OF TRIP-MAKING DATA PECULIAR TO THE SPECIFIC AREA, ARE THEN PRELIMINARY STEPS TO BE TAKEN IN A MORE TRADITIONAL TRANSPORTATION ANALYSIS. A BENEFICIAL CONCEPT INHERENT IN MICROAREA ANALYSIS IS THAT IT DOES NOT HAVE TO BE LIMITED TO POOR AREAS, AREAS DEFINED AS HAVING THE GREATEST TRANSPORTATION NEGLECT. AN AREA WITH A HIGH CONCENTRATION OF UPPER INCOME BUT GENERALLY ELDERLY POPULATION WOULD BE ANOTHER EXAMPLE OF A MICROAREA THAT MAY NEED SPECIAL-SERVICE PLANNING. THE FINAL PRODUCT IS A HIGHER LEVEL OF TRUE TRANSPORTATION SERVICE TO ALL THE RESIDENTS OF THE METROPOLITAN AREA. /AUTHOR/
