The goal of most transportation demand management (TDM) programsis the reduction of single-occupant-vehicle (SOV) use. The selection and packaging of TDM measures are critical in devising and implementing an effective program. The basis for the selection process can come from specialized transportation surveys. One such survey administered at the US Department of Transportation (DOT) headquarters in Washington, D.C., is reported. The survey was distributed to 11,568 DOT employees, with a response rate of 41 percent. Only 16 percent of respondents commute by SOV. The Washington, D.C., core average is nearly 31 percent. DOT has excellent rideshare participation, with an overall occupancy of 1.89 employees per automobile. Several attitudinal questions were asked to investigate possible mode shifts if the headquarters were relocated near Union Station. DOT employees considerdiscounted transit passes and increased parking costs strong incentives to change modes of travel. It is anticipated that a combination of transit subsidies, rideshare programs, and flexible work schedules will be considered for the possible consolidation of DOT. (A)
