Travel data, also known as household travel or activity data, usually consist of a travel diary or log of all the trips (tours or trip chains) undertaken by an individual or a household druing a given period of time (usually one day). These data are distinctly different from the more common traffic volume counts measured in vehicles per hour over days or months at specific locations in the transportation network. Travel diaries include and origin, destination, travel mode, departure time, travel time, distance and travel party for each trip. Moveover, very disaggregate information about the houlsehold, individuals, vehiches, workers and often attitudes are usually assoicated with the trip information. Travel datasets are large and complicated both for the data collectors and also in terms of participant burden. For example, the Federal Highway Adminstration's (FHWA) 2009 National Household Travel Survey (NHTS) dataset has 206 different variables organized into four dat tables. Vermont's 1690 households reported 10,865 trips. However, the travel diary data is critical as it is the only source of data that allows analysts to estimate total vehicle miles of travel for different sub-groups or residents of different locations including the mode choices and spatial patterns. There are three main objectives of this project are intended to facilitate discussion of whether Vermont should purchase and NHTS Add-on sample in 2015: 1) To tabulated the travel data needs of Vermont stakeholders, 2) To assess the strenths and weaknesses of using the NHTS Add-on to mee the Vermont travel data needs, and 3) To outline alternatives for collecting VT travel data including frequency, key variables and budget considerations.
