A transit bus is a public transportation vehicle designed for short-distance travel within cities and metropolitan areas. These buses typically follow fixed routes and schedules. They can be powered by diesel, electric, hybrid, or alternative fuels.

Transit buses operate on a scheduled route system, making multiple stops to pick up and drop off passengers. They are managed by municipal transit authorities or private operators. Payment is usually made through fare collection systems, including cash, cards, or contactless methods.

Transit buses come in various types to accommodate different passenger needs and urban environments:

Standard Transit Buses: Typically 30 to 40 feet long and designed for city commuting.
Articulated Buses: Extra-long buses with a flexible joint for higher passenger capacity.
Electric Buses: Battery-powered, environmentally friendly options. 
Trolley Buses: Electric-powered buses connected to overhead wires, used in some cities.
Double-Decker Transit Buses: Two-level buses for maximizing seating capacity in high-traffic areas.

Transit buses typically range from 30 to 60 feet in length, depending on the model and passenger capacity. Standard city buses are usually 40 feet long, while articulated buses can extend up to 60 feet.

The main difference between a transit and trolley bus lies in their power source: 

Transit buses are usually diesel, hybrid, or battery-powered and can travel freely on roads.
Trolley buses rely on overhead electric wires, which limit their routes but provide a quieter and more sustainable transportation option.

Yes, most modern transit buses include low-floor designs, wheelchair ramps, and priority seating to ensure accessibility for passengers with disabilities. Many also have audio and visual announcements for better navigation.

A standard 40-foot transit bus can typically seat 30 to 40 passengers, with additional standing capacity. Articulated buses can accommodate up to 100 passengers, depending on the layout.
