The Metropolitan Area Commuter System is rolling out technology upgrades this week, including a website with up-to-the-minute bus tracking. [...] MACS is now linked with RouteShout, a smartphone app that allows bus riders to track departure times and other bus schedule information, and Google Maps for easy trip planning. The borough coordinated with technology companies and installed GPS systems and tablets in all of the buses to make the technology upgrades happen. Barth said he hopes to install more of the screens —similar to what airports provide informing travelers of flight departure and arrival times — if money allows.
