regularly calibrating them would translate into increased costs in real-world application. This is the reason for its low score in the cost criteria. If in the future, sensors
can be viable, this concept will become the preferred one.
3 Modeling the Solution
Our study on the height difference between the first stair and the ground led to the
determination of the average height of the first stair to be 400 mm. In concept 2,
step height is reduced to 200 mm, as design involved mechanical system installation
cost is low and will require minimal maintenance during operation. As system is
directly connected to the door, it can be operated by any person with ease. This
system provides flexibility to detach door, and system is to provide door opening
without unfolding the stairs.
4 Conclusion
The above-proposed design aims at utilizing the opportunity to ease and enhance
the experience of the children, elderly, and differently abled commuters of buses.
The design is aimed to be cheap and simple enough to be easily retrofitted into buses
