2001–2002 Southern California Regional Travel Survey

The 2001–2002 Southern California Regional Travel Survey collected data on household characteristics and travel behavior to update regional travel demand models. It covered six counties including Imperial, Los Angeles, Orange, Riverside, San Bernardino, and Ventura.

Data Collection Agency

The Southern California Association of Governments (SCAG) contracted with NuStats Partners to conduct the survey following the 2000 decennial census.

Methodology

Survey data collection occurred in 2001 and 2002 using computer-assisted telephone interviewing (CATI) and travel diaries. Roughly 17,000 households completed the survey. An additional global positioning system (GPS) sample was taken for the purpose of auditing the self-reported diaries; data derived from this sample are provided for download below. Battelle provided data collection support for the GPS sample.

Survey Records

Survey records include 40,376 participants.
