MADISON, Wis. & NATIONAL HARBOR, Md.--(BUSINESS WIRE)--TrafficCast International, Inc., today introduced BlueTOAD™, (Bluetooth Travel-time Origination And Destination) traffic monitoring technology that traces anonymous Bluetooth signals to derive travel times, road speeds and vehicle movements. BlueTOAD delivers accurate traffic data to meet specific needs of Departments of Transportation, traffic engineers and traffic information providers for reliable reports of road conditions.
“BlueTOAD will enable granular road speed coverage, particularly for areas that more traditional sensors cannot address efficiently, such as arterials and on-ramps,” said Neal Campbell, CEO of TrafficCast. “It is also an effective planning tool, with installations cost-effectively delivering more thorough data on vehicle patterns than typical methods like car counts and monitoring strips.”
BlueTOAD devices receive signals emitted by Bluetooth-equipped electronics such as mobile phones, car radios, navigation devices and computers. Only the internal identifier, known as the MAC address, is transmitted to the BlueTOAD receiver; these are not associated with individuals, so personal information is unavailable and the data is anonymous.
Bluetooth is a communications networking protocol used to wirelessly connect electronics devices over relatively short distances. In a span of eight years 1.5 Billion Bluetooth devices have shipped. Beyond mobile devices, it is predicted that by 2013 two out of every three new cars will offer Bluetooth connectivity.
TrafficCast’s adoption of Bluetooth employs a novel, patent-pending implementation based upon industry-leading, mobile-device hardware and software platforms. It incorporates Zigbee wireless mesh networking with cellular packet backhaul for real-time traffic monitoring. Based upon this platform configuration, TrafficCast projects up to 4x cost saving over most other implementations.
With BlueTOAD, travel time is sampled directly from device movements, and can sort through the implications of vehicle movements in congested road segments. More broadly, BlueTOAD data integrates with TrafficCasts’s comprehensive road speed data product, Dynaflow 2.0, released in April and market-tested for unprecedented coverage, accuracy and reliability.
Separately, BlueTOAD communications modules enable aggregation of data from multiple monitoring devices for consolidated backhaul to traffic operations centers. Through proprietary data protocol conversion software, BlueTOAD can access data from dissimilar technologies and provide cost-effective real-time access to information sources over a single channel.
