Rapid Flow Technologies LLC has recently spun out of Carnegie Mellon University with the goal of introducing new Intelligent Transportation Systems (ITS) technologies into the marketplace. Rapid Flow was created to commercialize the Surtrac adaptive traffic signal control technology developed in the Robotics Institute at Carnegie Mellon as part of the Traffic21 research initiative. Rapid Flow is also a part of the NSF I-Corps Site program at Carnegie Mellon.



The company’s founders include the original inventors of Surtrac, who have successfully expanded the initial pilot deployment of Surtrac in Pittsburgh to a network of 47 intersections over the past three years. Rapid Flow holds an exclusive license to the patented Surtrac technology from Carnegie Mellon University, and the University has a stake in the company.

In addition to Surtrac, Rapid Flow is also engaged in the development of ubiquitous Bluetooth AVI sensor network technology for ITS performance modeling and other applications through a Small Business Innovation Research (SBIR) grant from the U.S. Department of Transportation.
