Boston Celtics first round draft pick Kelly Olynyk joined Massachusetts Transportation Secretary Richard Davey at a Sept. 19 event to encourage Celtics fans to use the Massachusetts Bay Transportation Authority (MBTA) to TD Garden this season. They boarded the Green Line at Kenmore Station—where the MBTA activated electronic message boards, displaying information about which Green Line trains will be the next to arrive—before traveling to North Station.

“For the first time in the 100-year history of the Green Line, customers on the outbound platform will no longer have to guess which train is coming next,” Davey said. The new system will continually display the destinations of the next two trains approaching Kenmore.

The Green Line customer information system is the latest component of Davey’s plan to enhance the public transit experience through the use of high-tech innovations at minimal cost to the MBTA. The countdown signs are now in operation on every platform along the Red, Orange, and Blue lines; smartphone apps also put real-time information in the palms of customers’ hands.
