Feds move to require new cars to ‘talk’ to each other

The Pittsburgh region already is using smart traffic signals developed by CMU in parts of Shadyside and Cranberry, and the city recently received a $10.9 million grant to develop a smart spine to help move traffic in and out of the Golden Triangle from the east. CMU researchers say it would be an easy software adjustment to have the traffic and vehicle information work together in a cohesive system monitored at a central location. “This [rule] is a welcome step forward,” said Raj Rajkumar, co-director of the university’s General Motors Connected and Autonomous Driving Collaborative Research Laboratory, where he does research on self-driving vehicles. He said vehicle-to-vehicle communication would be “the perfect complement” to self-driving vehicles.
