What feature allows for easier access to a bus for passengers?

The kneeling mechanism is a feature designed to enhance passenger access to a bus, particularly for individuals with disabilities or mobility challenges. This mechanism lowers the vehicle's entrance step, bringing it closer to the ground, which reduces the height that passengers need to step up or down when entering or exiting the bus. This is especially beneficial for seniors, people using wheelchairs, or those with other mobility impairments, as it makes boarding and alighting significantly easier and safer.

While wider doors, ramps, and adjustable seating can also contribute to accessibility and comfort for passengers, the kneeling mechanism specifically targets the vertical distance related to the bus's entry point, making it a direct method for facilitating easier access. Wider doors may help accommodate larger mobility devices but do not address the step height directly. Ramps provide access, but they are not present on all buses, and adjustable seating improves comfort but does not enhance access. Therefore, the kneeling mechanism is the most relevant feature focused on making entry and exit more accessible for all passengers.
