Travel Behavior Study

The Napa County Transportation and Planning Agency (NCTPA) is conducting a “Travel Behavior Study” which is a joint project with Napa County and is the first step in developing a comprehensive Countywide Transportation Plan. This study will allow us to better understand the details of how travelers move inside Napa County, including visitors.  Most standard transportation data sources focus on the daily commute travel because this is generally when the system is most congested.  In Napa, with nearly 3 million visitors per year, understanding the movements of visitors within the county is of critical importance to understand traffic patterns and transportation demand. 
The study will make use of several different sources of information including basic traffic counts at selected locations, mailed surveys based on the capture of license plate numbers, cell phone tracking data (information about where a sample of vehicles travel within Napa County without identifying the owner/driver) and finally, detailed intercept interviews at selected locations, including 30 wineries throughout the county.

Community Representation

A Community Advisory Committee (CAC) is formed to assist NCTPA and the County of Napa with the development of this study.  The CAC will meet during different stages of the study.  Members of the committee are comprised of representatives from business and wine industry groups, and other community stakeholders.  To view past meeting agendas with topics of discussion click hereTo view the committee member list click here.
