Bluetooth Traffic Monitoring Technology
Source: University of Maryland
Beginning in late 2007 the University of Maryland, with support from the Maryland State Highway Administration, developed an anonymous probe technique to monitor the travel time on highways and arterials based on signals available from the point-to-point networking protocol commonly referred to as Bluetooth. The majority of consumer electronic devices produced today come equipped with Bluetooth wireless capability to communicate with other devices in close proximity. For example, many digital cameras use Bluetooth for downloading pictures to a laptop computer. It is also the primary means to enable hands-free use of cell phones.
