In the late 1960s, bus ridership decreases combined with rising expenses forced WPS to reduce deficits by cutting back on service.

The system is called "radial" because the layout of the routes brings all buses to the downtown transitway and then radiates them out in a spoke-like fashion to cover the service area.

It is called a "pulse" system because all routes are timed to arrive at the downtown transitway at regular intervals, allowing for transfers with little or no waiting.

Green Bay Metro partners with Via to provide microtransit service utilizing smartphone applications and a similar fare structure.

[7] Zone 1 (red) services Green Bay's west side, including destinations such as Northeast Wisconsin Technical College.

[8] Limited service routes #71, #75, and #78 operate on regularly scheduled school days and is open to the general public.

[9] On February 26, 2001, all Metro operations relocated from the 318 South Washington Street facility to a new Transportation Center located at 901 University Avenue.

The Washington Street facility was originally constructed in the late 1800s for administration, maintenance, and storage of an electric streetcar system.

Both Wisconsin Public Service and the city of Green Bay financed many building expansions and enhancements over the years.

Operational efficiencies of a modern facility and the reduction of "deadhead" mileage from the garage to the primary hub have been cost-saving benefits.

Passengers at the Transportation Center benefit from a staffed information counter, real-time bus arrival board, automated pass dispenser, spacious climate-controlled seated waiting area, vending machines, and public restrooms.

At the heart of the facility stands a 300-foot long canopy with 14-foot vertical clearance for bus traffic and a width sufficient for protecting the passengers from sun and rain.
