Future of Engineering

The mobile was initially invented to enable people to stay connected on the go. Additional features such as music, games and internet connection made it more attractive. Now it's going to help out scientists who are trying to find their way around traffic.



Engineers at the Indiana Department of Transportation have tried to monitor travel time by tapping into the signal emerging from the bluetooth phones and other devices that we carry on our way to work.

The method picks up the identifying "addresses" from Bluetooth devices in consumer electronics. Because each device has its own distinct digital signature, its travel time can be tracked by detectors installed at intersections or along highways and other locations.

"Information is a commodity people are aggressively seeking, and this method promises to cost effectively provide information that has never been widely available to travelers," Bullock said.

Data collected through this technology would help in building a better traffic signal timing, as well as real-time traffic information for motorists. It can also monitor the movement of long queues thus enabling customers to get better service in airports and other places.

Travel time monitoring is sure to help in the growth and development of a well planned city.
