Data-driven bus service set to roll out

Imagine a mass transit system that could figure out on a daily basis where people are and where they want to go, and then get them there — nonstop — on luxury buses for just a few dollars more than a T ride costs.
That’s the concept behind a first-of-its-kind “pop-up” bus service scheduled to begin trial runs in mid-May with at least four nonstop commuter routes in Brookline, Boston, and Cambridge.
