New MTA web service tracks B’klyn bus

Brooklyn straphangers will now know when their B63 bus will arrive without having to stand in the street.

The MTA will roll out “BusTime” on it’s third route today — the B63, which runs between Fort Hamilton and Cobble Hill.

The free bus-tracking Web service allows riders to simply check their smartphones to find out how long until the next coach arrives and even see its current location.

The two Manhattan routes got the high-tech treatment in October.

In time, agency chiefs hope to roll out the program across the entire system.

Each B63 bus was equipped with a computer chip — which is part of the technology that will be used to eliminate the MetroCard — that allows the bus location and time until arrival to be displayed on handheld devices.
