Seating Capacity: Sub-urban buses are often designed to carry a significant number of passengers, providing a balance between passenger capacity and route flexibility.

Comfort: These buses might offer basic comfort features such as cushioned seating, ventilation, and possibly air conditioning.

Luggage Space: Given that sub-urban routes might involve longer distances, there might be provisions for luggage storage within the bus.

Accessibility: Accessibility features for passengers with reduced mobility could be a consideration, including low-floor entry and space for wheelchairs.

Efficiency: Sub-urban buses might be designed for fuel efficiency and optimized for longer routes between towns and cities.

Safety: Safety features such as ABS, emergency exits, and possibly fire safety measures are important for sub-urban buses.

Route Optimization: Some sub-urban bus models may be equipped with technology for route optimization, real-time tracking, and passenger information systems.

Environmental Considerations: Depending on the region and regulations, sub-urban buses might also focus on emissions reduction, potentially through alternative fuel options or advanced engine technology.

Driver Comfort: Longer routes often mean longer driving hours, so the driver's cabin might be designed for comfort and ease of operation.
