ESTIMATION AND EVALUATION OF DIVERTED AND GENERATED (INDUCED) TRAFFIC

TRAVEL BEHAVIOR IS PRESENTED AS ESSENTIALLY BOTH A TEMPORAL AND A SPATIAL PHENOMENON. RELIANCE ON PURELY CROSS- SECTIONAL DATA IS CRITICIZED, SUCH AS THE STANDARD ORIGIN- AND-DESTINATION SURVEYS, WHICH MAY HAVE POORLY DEFINED SPATIAL AGGREGATION, AND CAN ONLY ACT TO SUPPRESS RATHER THAN TO CLARIFY FUNDAMENTAL RELATIONSHIPS. IT IS PROPOSED THAT VALID SHORT- AND LONG-RUN INFORMATION IS NEEDED TO TREAT THE INDUCTION AND DIVERSION PROBLEMS. THIS INFORMATION MAY BE OBTAINED FROM A CONTINUING PANEL SURVEY OF A SAMPLE SELECTED WITHOUT REGARD TO THE OCCURRENCE OF A PARTICULAR EXPERIMENT. THIS CONTINUING SURVEY MAY BE CONDUCTED THROUGH PERIODIC USE OF A SELF-ADMINISTERED TRAVEL DIARY TO STUDY HOUSEHOLD TRAVEL BEHAVIOR. COSTS ARE ESTIMATED TO CONDUCT A CONTINUING SURVEY IN A SUBURBAN COMMUNITY. THE MOST EFFICIENT SINGLE ESTIMATE OF AVERAGE DAILY TRIP MAKING, ALLOWING FOR DATA COLLECTION COSTS, APPEARS TO BE THE ACQUISITION OF CONSECUTIVE, THREE-DAY, WEEKDAY SAMPLES. IT IS CONCLUDED THAT SUCH A STUDY SHOULD PROVIDE A MORE EFFICIENT MEASURE OF INDIVIDUAL FAMILY TRAVEL THAT MAY BE IDENTIFIED WITH THE PATTERN AND INTENSITY OF AGGREGATE DAILY TRAVEL WITH RESPECT TO BOTH TIME AND LOCATION.
