After only 12 months of operation, the Chicago Transit Authority's new Orange Line, providing rapid rail service from Chicago's Loop to Midway Airport, had reached a weekday ridership of 37,500 passengers. Preliminary analysis indicated that the line had increased transit ridership overall in the southwest corridor by 31.0%, raising transit's mode share of work trips from 16.4% to 21.5%. Based on an on-board rider survey done after 4 months, nearly one-quarter of daily boardings were new to transit, representing former automobile commuters or new trips for which the automobile was a candidate. That share grew to over 25% by the end of the first year. Core, secondary, and tertiary markets were defined in March 1994 in the southwest corridor, together providing 84% of the line's ridership. Demographic and travel characteristics of the transit riders surveyed are compared with comparable market-area data from the 1990 U.S. Census. Survey data regarding the intensive marketing campaign that accompanied the line's opening are analyzed. A separate analysis comparing diverted and new transit riders with those who shifted from other transit services is given. A series of guidelines is drawn for successfully inaugurating major transit-service improvements designed to decrease reliance on automobiles. The origin-destination and access-mode data from the March survey were also used to measure the net decrease in automotive cold starts and vehicle kilometers traveled. These measures were developed to estimate the air-quality benefits of this new rapid-rail service. |
