DEVELOPMENT OF THE MICHIGAN DISAGGREGATE DATABASE ON DRIVING EXPOSURE.

RECENT INFLUENCES ON THE DESIGN OF AUTOMOBILE DRIVING EXPOSURE SURVEYS ARE BRIEFLY DISCUSSED RELATIVE TO OTHER AREAS OF TRAVEL DEMAND RESEARCH. THE CASE FOR THE COLLECTION OF MICRO DATA IS ARGUED AS BACKGROUND TO THE DEVELOPMENT OF A MAJOR DRIVING EXPOSURE SURVEY EFFORT KNOWN AS THE MICHIGAN DRIVING EXPERIENCE SURVEY, WHICH INTERVIEWED 7581 DRIVERS STATEWIDE DURING ALL OF 1976. A SUMMARY OF SAMPLING, INTERVIEW, DATA PREPARATION AND QUALITY CONTROL METHODOLOGIES IS GIVEN, WITH A DESCRIPTION OF STUDIES SO FAR RELEASED AND EXAMPLES OF FINDINGS. IN COMMENTING ON MICHIGAN'S EXPERIENCE WITH THE METHODOLOGY, WHICH WAS IMPLEMENTED AT LOW COST ENTIRELY WITH THE SPONSORING STATE AGENCY'S OWN PERSONNEL, SURVEY MANAGEMENT IS IDENTIFIED AS THE AREA MOST CRITICAL TO SUCCESS.(Author/publisher).
