Agencies in the Houston region have traditionally used toll tag readers to provide travel times on freeways and High Occupancy Vehicle (HOV) lanes, but these systems require large amounts of costly and physically invasive infrastructure. Bluetooth is a widely used technology embedded in cellular telephones and in-vehicle applications for exchanging data over short distances. The initial demonstrations of wireless address matching were primarily designed to prove the ability for Bluetooth technology to produce matches between two points on a roadway outfitted with the proper Bluetooth reader equipment, with a resulting travel time and speed calculated. Costs for Bluetooth travel time measurement systems are one to two orders of magnitude below costs for traditional toll tag reader equipment, depending on the application. This cost advantage could significantly lower the threshold for hundreds of agencies and private entities to enter the travel time measurement market, but there is little guidance on the application. Development and testing of various prototype software and hardware platforms were conducted to use the anonymous Media Access Control (MAC) address from each Bluetooth device to measure and report real-time traffic conditions.
