摘要：	Traveler route choice behavior is the cornerstone of numerous advanced traffic management technologies. Yet, few datasets of actual travel routes have been collected and analyzed. There are two specific objectives of the analysis work conducted in this NEUTC research project (the data collection was only partially funded by this project). The first was to advance the methodological aspects of using GPS to collect route data, including constructing the spatial model that automatically identifies trip ends in the large-scale continuous GPS data stream. This work makes use of 10-days of in-vehicle travel routes collected from 256 households using Global Positioning System (GPS) receivers from 2002 to 2003 in Lexington, Kentucky (population 250,000). Information for each vehicle, such as speed, latitude, longitude, and heading was recorded every second or every five seconds (depending on the power feature in the particular vehicle and the corresponding settings of GPS devices). A travel habits survey was also conducted with every driver in each household after the ten-day data collection cycle was completed. This dataset was used for the second project objective: to estimate routing efficiency and selection patterns by determining if route choice is influenced by attitudes, travel habits, roadway characteristics, congestion, or a combination of a few or all of these elements. Surveys were collected from 524 drivers in the 256 households.
