Neighborhood Travel and Activity Study (NTAS)

Caltrans has awarded the University of California, Irvine (UCI) with funding to conduct the Neighborhood Travel and Activity Study (NTAS). This study will help close a crucial data gap in land use – travel behavior studies by examining the effects of small area land use policies such as targeted infill development, transit-oriented land uses near stations, or similar localized policies.

The NTAS is being conducted by the University of California, Irvine led by Dr. Douglas Houston. For more information, please visit the study website at:


The results of this survey-based research will provide valuable information to help ensure that future transportation projects reflect community needs and that transportation funds are spent wisely.


This study will survey approximately 300-600 households in rail transit corridors in the Los Angeles area during October-December, 2012. The research team will collect information about daily travel patterns, household characteristics, transportation resources, and residential location preferences.


Households contacted to participate in this study can visit the study website at to register their interest in participating in the study.

Participating households will have a 1 in 10 chance of winning a $100 grocery gift card.
