BUS STOP NAME INDICATION SYSTEM
If the passenger can see or is not visually impaired, they may see outlines of useful landmarks that indicate the approach to their bus stop. The near or totally blind rely on identifying directional changes that the bus makes to find their bus stop. Asking about the place to fellow passenger the driver is another alternative although it is very uncomfortable.
This system has a transmitter at every bus stop which continuously transmitting a unique ID .Bus contains a main unit which receives transmitted ID and indicates the passengers the arrived stop.
Transmitter unit comprises of a Microcontroller (AT89c51) unit which generates a unique bus stop ID for every bus stop and multiple transmitter units. IR LED to transmit the code. Receiver unit comprises of IR receiver unit containing TSOP1738 to detect and demodulate the transmitted code which is detected by the microcontroller and indication about the bus stop is produced.
Another system: A passenger notification system
Here a sensory announcement such as verbal or vibrational is made available to the passengers at each stop by the driver. There is a switch which is responsive to the motion of the driver's arm with respect to the torso. The switch when activated initiates a pre recorded message.It is also mandeted by the persons with disabilities act that the driver must annnounce the name of each stop. Thissystem can thus be very useful to the driver.
The main blocks in the system are:
--------- -------------- -----------------
actuator | | audio/code| | audio/visual|
switch | | player | | display |
--------- -------------- -----------------
