MINIMUM TIME PERIODS-ORIGIN AND DESTINATION SURVEYS

AN ATTEMPT WAS MADE TO DETERMINE THE ACCURACY THAT CAN BE EXPECTED FROM THESE LESS COSTLY AND TIME SAVING SHORT-TIME SURVEYS, AND TO DETERMINE IF CERTAIN SHORT-TIME SURVEYS YIELD MORE ACCURATE RESULTS THAN OTHERS. TIME PERIODS RANGING FROM ONE HOUR TO 16 HOURS WERE SELECTED FOR STUDY. THE INTERVIEWS FROM ALL OF THE SHORT-TIME SURVEYS WERE EXPANDED TO A 24 HOUR TOTAL AND COMPARED TO THE KNOWN 24 HOUR VOLUME INTERCHANGE TO EACH ZONE. FINDINGS ARE BASED ON ORIGIN AND DESTINATION DATA COLLECTED AT OPELOUSAS AND ALEXANDRIA, LOUISIANA AND LANSING, MICHIGAN. THE 16 HOUR STUDY (6 AM - 10 PM), WAS FOUND TO BE THE MOST ACCURATE. THIS STUDY WILL PROVIDE DATA COMPARABLE TO THAT FOUND IN THE 24 HOUR SURVEY. THE 8 HOUR PERIOD, (10 AM - 6 PM), SUPPLIED MORE RELIABLE DATA THAN THE 12 HOUR, THE 10 HOUR, OR OTHER 8 HOUR PERIODS INCLUDED IN THIS STUDY. RESULTS FROM THE 12 HOUR, THE 10 HOUR, AND OTHER 8 HOUR STUDIES PROVIDED DATA CONSIDERED STABLE ENOUGH TO MEET THE REQUIREMENTS OF THE PLANNING SECTION. MAXIMUM ERROR LIMTS OCCUR IN THE LOWER VOLUMES; AS LARGER VOLUME RANGES ARE CONSIDERED THE ERROR LIMITS DECREASE. /AUTHOR/
