Carnegie Mellon University spinoff targets traffic flow

Traffic changes constantly in cities and only worsens, says Greg Barlow, whose company Surtrac Inc. developed a system to improve flow and reduce stops.
He claims an overall 25.8 percent travel-time improvement in tests in East Liberty, and said on Wednesday that Pittsburgh Public Works officials want to see it proved over a longer period.
“Pittsburgh is willing to try new things and be part of innovation,” said Barlow, who intends to incorporate the Carnegie Mellon University spinoff whose computer system improves not only travel times but speed and waits at lights. A bonus, he said: reduced emissions.
