BROOKLYN - The MTA is phasing in a new bus service that it expects will improve service along Nostrand Avenue.

The new initiative, called the Nostrand Avenue Bus Rapid Transit Service, will generally follow the route of the "B44" bus, the MTA says. The buses will also have traffic-signal priority south of Flatbush and a faster, more modern fare-collection system.

Officials for the NYC Transit and DOT are hopeful that the bus service will be implemented by the summer of 2012.
