Port Authority CEO Katharine Kelleman said because BRT is an on-street system that will change traffic patterns, there’s no real way to pilot the full system; doing so would be too disruptive.

“But we can add some improvements without waiting for the full project, so we’re definitely looking at that,” she said.

Those possible improvements include signal prioritization or preemption, which helps keep traffic moving by ushering mass transit vehicles through busy intersections or corridors using smart traffic signals. Kelleman said Port Authority is working with both the City of Pittsburgh and Carnegie Mellon University to get its buses talking with surrounding infrastructure.
