Commuter bus systems are usually categorized as public transportation, especially for large urban transportation networks. These routes usually cover longer distances than most transit bus routes, but are still short, usually 40 miles in one direction. An urban-suburban bus line usually connects the suburban area to the city center.

The vehicle can be something as simple as just a converted school bus (which sometimes already has overhead racks for storage) or a minibus. A commuter bus, which is a standard transit bus modified to have some of the functions of a long-distance intercity bus, can often be used. Vehicles are designed for people with disabilities (with an elevator or ramp in the front) and therefore have several high-back seats, usually in the front, that can be folded down for wheelchairs. The remaining seats are padded reclining seats with individual lighting and overhead storage drawers. Since this is a commuter bus, it has some (but not many) standing seats, stop request devices, and a ticket booth. This model also has a bike rack at the front to accommodate two bicycles.

Suburban models in the United States are often used in parking and fare services and are very common in the New York City area, where New Jersey Transit Buses is a major operator serving widespread bedroom communities.
