An Audio Based Bus Proximity Indicator For Visually Challenged People

摘要

It is always good to know a bus commuter waiting at a stop gets to know how far a bus is. Based on the investigation about daily activity characteristics and modes of the blind, the study found that the main difficulties encountered in a trip of the blind included walking on the road, finding way, taking a bus and looking for usual life-area. If his route of travel happens to be common for more than one bus- route number, it is even better for him to know which is the nearest bus or the earliest arriving bus. This will enable him to opt for the bus or some other mode of commuting. This becomes very useful for the physically challenged commuter, as after knowing in advance the bus arrival he/she will be ready to accommodate in the bus. A thought of project Bus Proximity Indicator is the best solution for the above situation and is best suitable for the visually challenged people. In this a wireless RF linkage between a certain bus and a bus stop can be used for determination of the bus proximity that help's commuter to know how far his bus is and to identify the bus number through audio signal from audio playback recorder.
