This paper reports on the anonymous tracking of Bluetooth enabled consumer electronic devices to measure the travel time, or space mean speed, of travelers. This sampling technique was deployed at six interstate locations and two signalized arterials in the Indianapolis, IN metropolitan area the week of the NASCAR Brickyard 400. The week prior to the race before data was also collected from a subset of those sites. The day of the race, almost 19,000 unique MAC address were captured at the eight locations. From that information real-time travel time estimates were provided to Indiana Department of Transportation (INDOT) mobile data terminals. After the race, the data was processed to obtain travel time plots and origin destination matrixes to provide a quantitative evaluation of race day traffic management operations. Selected reports and charts from that analysis are discussed in the paper.
