A LARGE PORTION OF RECREATIONAL VEHICLE (RV) USE IS CONFINED TO SHORT TRIPS. IN 1976, 35% OF THE TOTAL VACATION TRAVEL WAS UNDER 1,000 MILES PER RV. NEARLY ONE-FIFTH (17.3%) OF THE RVS WERE USED LESS THAN 100 MILES THAT YEAR; 35.3%, MORE THAN 3,000 MILES; 17.7%, MORE THAN 5,500 MILES.

Percent Distribution by Trip Length of Vacation-
Miles Traveled in Recreational Vehicles

THE MOTORCYCLE INDUSTRY COUNCIL PRESENTS TWO CONCEPTS OF AVERAGE ANNUAL
MILEAGE. THE FIRST CONCEPT IS DEFINED AS THE "ACCUMULATED MILES PER
YEAR" BECAUSE IT IS THE ANNUAL AVERAGE OF ALL MILEAGE ACCUMULATED ON
THE VEHICLE. THE
THE "MOMENTARY MILES PER YEAR" IS DEPENDENT ON THE
MILEAGE ACCUMULATED IN A PARTICULAR YEAR ACCORDING TO THE VEHICLE AGE
AND THE CONCEPT THAT ANNUAL MILEAGE DECREASES AS THE MOTORCYCLE AGES.

GENERALLY, THE VALUE OF MOMENTARY MILES PER YEAR IS ABOUT 30-40% LESS
THAN THAT OF ACCUMULATED MILES PER YEAR. THIS DIFFERENCE EXISTS BECAUSE
THE MAJORITY OF MILEAGE ACCUMULATED ON A MOTORCYCLE OVER THE VEHICLE LIFE
IS ACCUMULATED DURING THE FIRST AND SECOND YEARS OF USE, AND THE MAJORITY
OF MOTORCYCLES IN USE IN A GIVEN YEAR ARE OLDER THAN TWO OR THREE YEARS
OLD. THUS, THE MAJORITY OF MOTORCYCLES IN USE IN A GIVEN YEAR ARE ACTUALLY
TRAVELING LESS THAN THE AVERAGE OF MILES ACCUMULATED OVER THE CURRENT
VEHICLE LIFE, AND THEREFORE, MOMENTARY MILES PER YEAR IS LESS THAN
ACCUMULATED MILES PER YEAR.

THE ANNUAL HOUSING SURVEY, CONDUCTED EACH YEAR SINCE 1972 BY THE BUREAU OF
THE CENSUS, ASKS GENERAL QUESTIONS ON MEANS OF TRANSPORTATION TO WORK,
TABLE 1.73 AND TABLE 1.74 GIVE U.S. TOTALS DERIVED FROM THE 1976 SURVEY.
FROM THIS DATA WE SEE THAT MASS TRANSIT IS USED MOST OFTEN IN CENTRAL
CITIES (13% OF WORKERS) WHEREAS CARPOOLING IS MOST FREQUENTLY A MEANS
OF TRANSPORTATION TO WORK IN AREAS OUTSIDE OF SMSAS (20% OF WORKERS).
IN CENTRAL CITIES THE "WALKS ONLY" CATEGORY INCLUDED PEOPLE WHO LIVE
WITHIN WALKING DISTANCE OF THEIR PLACE OF EMPLOYMENT; OUTSIDE SMSAS IT
INCLUDES PRIMARILY FARMERS OR SUCH SELF-EMPLOYED PERSONS.
