In 2007, the Federal Transit Administration (FTA) sponsored an evaluation of the Bus Rapid Transit (BRT) service implemented between the South Boston Waterfront and the Logan International Airport. The Silver Line Waterfront BRT included various Intelligent Transportation Systems (ITS) elements, including:

• Computer Aided Dispatch/Automated Vehicle Location (CAD/AVL) communications system designed to electronically communicate vehicle location.
• On-board public address and variable message sign passenger information display, which announces all stops.
• Light-emitting Diode (LED) signs, providing schedule and general information
• Computerized information kiosks
• Automatic intrusion detection system to prevent unauthorized access to the tunnel, closed-circuit television systems, portal protection, and other, undisclosed security and anti-terrorism initiatives
• Transit fare vending machines

As part of the Silver Line Waterfront BRT service implementation, the Massachusetts Bay Transportation Authority (MBTA) installed two fare vending machines—one full service and one cashless—at each of the Logan Airport terminal stops. Terminal C, however, has only a full service fare vending machine. Full service machines cost $35,494, and cashless machines cost $23,420 each. The MBTA paid for the fare vending machines. Construction and installation costs, which were paid for by the Massachusetts Port Authority (Massport), totaled $275,000. Infrastructure costs, which were paid for by the MBTA and Massport, was an additional $593,000. The total cost of the deployment was $1.26 million, including equipment, infrastructure, and installation.
