The last time I visited a mall, an ad banner asked me to turn on the blue-tooth on my cellphone, so that i could receive certain updates. Can a similar software app be made for a cellphone which would receive updates from a transmitter on board a bus or a train which can inform the recipient the next station, the last station and other relevant information like nearest hospital, restaurant, railway stations and other buses they can take to other places. The system can be modified depending on the disabled person. For example a sound operated app for blind,etc. This system can prove equally useful for common man too.
