As Singapore is currently lacking in facilities that help aid the visually impaired navigate and board buses, my team decided to look overseas and research on how other countries cope with such issues. Mentioned below are a few examples of systems being used in other countries.
‘Passenger Bus Alert’ System
According to a research conducted in India by Gholap (2015), the Passenger Bus Alert System begins with the visually impaired approaching the bus stop with an RFID tag. Upon arrival, the RF unit at the bus stop will recognize the signals sent by the RFID tag and proceed to communicate with any nearby buses. It also mentioned that when the bus reaches, the Light Emitting Diode (LED) on board will be switched on, indicating to the driver of the presence of a visually impaired at the bus stop. Thereafter, the buzzer on the bus will be activated to alert the visually impaired that the bus has arrived. Furthermore, the bus routes will be also announced via speaker to the visually impaired.

‘Talking Bus Stop’ System
According to SPD (2014), persons with visual impairment can make use of the ‘Talking Bus Stop’ system to access real time bus information, such as which bus stop they are at, which buses are coming and when the buses are due to arrive. Speakers installed at the bus stops will be triggered to announce the appropriate bus information when a visually impaired approaches with a key fob.
