The Travel Survey was completed in 2003 and was used to support transportation model improvements for the 2004 and 2008 Regional Transportation Plans and other transportation studies. It was a survey of the daily travel habits of households within six counties of Southern California (Imperial, Los Angeles, Orange, Riverside, San Bernardino and Ventura. Surveys of this magnitude are conducted about every ten years. The previous survey was conducted in 1991. The next travel survey was conducted in the year 2011. The Southern California Association of Governments (SCAG) contracted Nustats, a nationally recognized research firm, to conduct the travel survey. The survey was funded by SCAG, LACMTA, Caltrans, RCTC, SANBAG and the California Air Resources Board.
The survey provides valuable travel characteristics to agencies responsible for planning and improving roads, carpool lanes, trains, buses and other features of our transportation system. It sheds light on how that system is being used and by whom. For example, electronic sensors can tell you the condition of your favorite freeway; but only through travel surveys do we get a sense of how many freeway trips are destined to nearby supermarkets, or perhaps to distant places of work. Transit agencies, likewise, use travel surveys to plan bus service between popular places. The Survey provides critical travel behavioral information and demographic data needed by SCAG to update the Travel Demand Model.
