Congestion monitoring technology  developed at the University of Maryland?s Center for Advanced Transportation Technology (CATT) is finding success overseas reports a recent Gazette article. The technology which has been adapted commercially by Traffax, Inc. monitors travel time of vehicles on both freeways and arterials based on re-identification of vehicles containing Bluetooth wireless equipment.

Companies can purchase units known as BluFax from Traffax, Inc. to monitor not only travel time of vehicles but of pedestrians as well. Using sensors that detect Bluetooth signals from devices such as cell phones and global positioning systems (GPS) Blufax can accurately estimate travel time along the freeway, arterial, or sidewalk where the units are set up. Because Bluetooth technology is unidentifiable as to what device it came from and whose device it belongs to; privacy concerns are nonexistent.

A company in Australia has found Blufax beneficial in measuring the delay imposed on vehicles due to road construction activities.  Because of Traffax?s overseas success they were asked to participate and present at an international trade panel which was geared toward small and medium-sized enterprises to encourage foreign trade.
