Passenger capacity refers to the maximum number of people that a vehicle, such as a bus, train, or airplane, can safely accommodate. This number is determined by factors like seating arrangements, safety regulations, and the design of the vehicle. For example, a standard city bus may have a passenger capacity of around 40 to 60 people, depending on its size and layout. Understanding passenger capacity is important for transportation planning and efficiency. It helps ensure that vehicles are not overcrowded, which can lead to safety issues and discomfort. Additionally, knowing the capacity aids in scheduling and resource allocation for public transport systems, such as those operated by public transit authorities.
