The project is being carried out in collaboration with the Napa County Transportation and Planning Agency. Transportation consulting firm Fehr & Peers has been hired to collect the data from residents, commuters and visitors. Fehr & Peers will set up infrared cameras and computer systems that can record drivers’ licence plates. These plates will be used to find the drivers’ home addresses through the Department of Motor Vehicles database. Fehr & Peers will then conduct a survey to ask the drivers about where they were going, how often they make those trips, and which roads they travel on, etc. An online survey will be conducted to know the commuting patterns of students and employees. Another company called Air Sage will collect anonymous GPS data from cell phones. Air Sage computers can track the cell phones as they move around on a map. They then classify the location based on the length of time spent there. Officials plan to complete data collection by February 2014. This data will then be refined and analysed to understand traffic patterns.
