MIT Professor’s IoT Sensors Make Roads Safer

Back in 2005, before smartphones were generally available, MIT Professor Hari Balakrishnan was so fed up with commuting delays in Boston that he built a mobile system to monitor road conditions.

He and his research team at MIT’s Computer Science and Artificial Intelligence Laboratory developed CarTel, short for car telematics. Using signal processing and machine learning, their sensing device for vehicles was able to infer the presence of potholes and other impediments from changes in traffic flow, which it measured with GPS and an accelerometer…

In 2010 Balakrishnan and two cofounders commercialized CarTel by launching Cambridge Mobile Telematics

Balakrishnan, an IEEE Fellow, is this year’s Marconi Prize winner for his “fundamental discoveries in mobile sensing, networking, and distributed systems.” The award, given by the Marconi Society, is considered to be the top honor in communications.
