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 announce 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
-- -- --
The detailed drawings and description of the system in this pdf:

BUS STOP NAME INDICATION SYSTEM
If the passenger has some residual vision, 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. Seeking confirmation from a fellow passenger or from the driver is another alternative although it does require a lot of confidence to do this.
Keeping in mind these problems, this system has been planned to facilitate a blind person or a person new to the area who doesn t have knowledge on bus stop information.
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. IRED to transmit the code. Receiver unit comprises of IR receiver (TSOP1738) to detect and demodulate the transmitted code which is detected by the microcontroller and indication is produced.
I will keep updating this page with more abstracts. Keep checking them. And don t ask me for Documentation and coding. I can just point you in the right direction. And a little googling goes a long way too

WORKING EXPLANATION
The plete circuit diagram of automatic bus station announcement system is discussed in this article.
Transmitter:
the code of each bus is transmitted from the bus by the transmitter circuit. ncoder IC HT12E is used to generate the code of the bus number. The encoder chip HT 12D has the 8 bit address and 4 bit data lines. any code for a bus can be sent to this. each corporation is separated from one another by the code used. the transmitter will activated in a pulsating form. astable multivibrator wired around IC 555 is used for this purpose.
Message section:
The voice chip APR600 is used to play the voice message. PR 9600 offers true single chip voiced recording. There is facility for the non-volatile and playback for about one minute. 4 different messages are recorded on the chip. A micro controller is also used for controlling the recording and playback.

will you mail about this topic" bus stop indication " overall information about it
