Another striking illustration of the elimination of recreational travel during the war is given in figure 13, which shows daily traffic volumes on the Merritt Parkway in Connecticut during corresponding periods of the spring and summer in 1941, 1942, and 1943. In 1941 there were very high traffic peaks on week ends and holidays, whereas in June and July 1943 there was less traffic on such days than during the business days of the week.

TRUCK TRANSPORTATION IN WARTIME

In table 4, the vehicle-mileages of passenger vehicles and trucks are given separately for main and local rural roads, for each year from 1941 to 1948, inclusive. Main roads are generally State highways, or primary State highways in cases where all or nearly all of the rural road mileage is under State jurisdiction. In 1948, nearly three-quarters of all travel on rural roads was on these main roads, as can be seen from the table, and 21 percent of this travel was by trucks. The discussion of truck traffic is confined to main rural roads because weight surveys have been made principally on this class of road since the 1936-38 prewar period.
