1984 D. C. CORE CORDON COUNT OF VEHICULAR AND PASSENGER VOLUMES

This project in the Spring of 1984 counted persons and vehicles entering the downtown employment area of Washington, D.C., between 6:30 am and 9:30 am to quantify demands placed on highway and transit facilities. This is part of a continuing surveillance activity. For the 3-hour period there was a 16 percent increase in persons entering downtown by all modes. Transit was used by 35 percent of these and another 35 percent were in multi-occupant autos. Transit ridership grew by 8 percent from 1983 to 1984. Following the April 1983 opening of Metrorail across the Potomac, transit ridership across the river crossings increased 12 percent. From 1981 to 1984, the number of vanpools into DC doubled. There was a 10 percent increase in automobiles into downtown from 1977 to 1984. Transit seats in service to downtown declined by 15,500 or 10 percent between 1982 and 1984. The most heavily traveled truck routes into the area were identified, along with the states of registration of autos entering the downtown. Between 1982 and 1984 the total surface vehicles went up by 9.8 percent between 6:30 and 7:30 am, by 2.5 percent between 7:30 and 8:30 am, and by 5.3 percent between 8:30 and 9:30 am. The greatest increases in transit ridership between 1982 and 1984 occurred before 8 am.
