AN ALERTING SYSTEM IN CITY BUSES

Bus information is an essential part of many intelligent transportation systems (ITS) applications in today’s world where everything is connected. India’s automobile population has significantly expanded in recent years, which has resulted in severe traffic congestion and pollution in metropolitan areas, especially during rush hours. Increasing the number of individuals who use public transportation instead of their own automobiles is an ideal solution to these problems (comfort, convenience and so on). The suggested system would employ a speech recognition system to enter the user’s chosen location and a voice module to notify the arrival details. The suggested system’s performance has been found to be encouraging, and it is anticipated to be helpful in India’s development of advanced public transportation systems (APTS). The major benefit of this gadget is that it offers a bus alerting system for simple navigation; the user receives notifications for their destination as well as voices that announce the bus’s data. The system also has a further blind protection function that, in the event of any abrupt accidents, detects them using a MEMS accelerometer sensor and sends SMS-based location-based notifications to the designated person of concern. 

Everyday struggles are different for each visually impaired person.

A number of behaviors, including learning and notably movement, are compromised because of their inability to perceive what is going on around them. The difficulty increases if they have to take public transit. Additionally, they rely on the goodwill of those around them in order to find the public transportation vehicle. They frequently aren’t even aware that they are at a bus stop. It is necessary to conduct research and develop systems that could enable these individuals to independently locate and utilize the public transportation system, just like a regular person, in order to increase their comfort and quality of life while using public transportation.

PROBLEM STATEMENT

Now days most of passengers a getting the problem of over reach their station due to large number of passengers in a bus caused by failure of passenger’s sound to reach operators(Bus conductor and driver) at a right time.

Also muted people face challenge to communicate with bus operator (conductor )
When the bus is full of passengers ,the fail to give sign when the reach their station.

PROJECT OBJECTIVES

The main objective is to design alerting system that will provide an effective communication.

SIGNIFICANT OF THE PROJECT

The proposed circuit system will help to;

To ensure the effective communication between passenger and operator (Bus conductor and driver)
It helps to locate at the bus station which can help the passenger to know where they are.

LITERATURE REVIEW



In literature review describes the details and important things in alerting system focusing on the present system which are being used and the proposed system.

DISADVANTAGE OF EXISTING SYSTEM

It is difficult to the passenger when the travelling to identify bus station because there is no user interface which can help a passenger to identify easily.

PROPOSED SYSTEM



The system describe d in this work of alerting system in passenger bus which can improve effective communication between passengers and bus operator

The following activities needed to be undertaken.

BLOCK DIAGRAM

PRINCIPLE OF OPERATION OF THE PROPOSED SYSTEM

The idea of this project is to have a transmitter that will activate the Arduino Uno that already attaching with the receiver module. The Arduino Uno Microcontroller will perform the process to take out the output

The buzzer is attaching at the output of Arduino Uno. At last ,the buzzer is ringing as the output of this project.

ARDUINO ATMEGA

The Arduino Uno is a microcontroller board is basing on the ATmega328 . It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.

The Arduino Uno is getting power via the USB connection or with an external power supply.
The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts. The power pins are as follows:
VIN. The input voltage to the Arduino board when it’s using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
5V.This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 – 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don’t advise it.
3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.
GND. Ground pins.

DISPLAY ANALYSIS

There are wide range of standard LCD (liquid Crystal Display) module .For this project a LMO16 (16X2) display has been preferred

Reasons for preferring are
They are economical
Easily programmable
Also have no limitation of displaying special and even custom characters
It has got the following ratings
Voltage – 5v
Current – 150mA – 200mA

Buzzer calculation

The sound pressure level of audible sound ranges from 0db through 120db .The selected audible sound level is 90db which
From decibel formula,Decible level=10log[I/Io]dB where I is the sound intensity measured in W/m2
Io is the standard intensity of 10-12W/m2
Then
90db=10log[I/10-12]dB
90=10logI-10log10-12
90=10logI+120
– 30=logI10
I=IX10-3W/m2
From,I=P/A where byP is sound power and A is a spherical area reached by sound
P=1X10-3X3.14X2X2
P=0.0125 W
Therefore, the selected buzzer must consume power of 0.0125W

GPS MODULE

The input vcc 3.0v to 4.2v
Current less than 50mA
Therefore its suitable because it can be powered or connected to 3.3v pin to the Arduino

RESISTOR ANALYSIS

R3
R3=V/I
Where V=3.3V,I=50mA
R3=3.3V/50mA
R3=66 Ohms

Proposed circuit

CONCLUSION

According to the function performing by this project the objective of providing effective communication between passengers and operators of the bus will eliminate. This project is beneficial to the transportation facilities that can help passengers to determine the place where they are. The bus’s transceiver is then informed of this location. There is an alarm in the bus unit alerting the presence of blind and a voice is sent to the user’s headset informing them that the specific bus has arrived if the names in the transceiver in the bus match with that of the name sent by the blind. With GPS assistance

RECOMMENDATION

According to the requirement of the proposed solution, the device especially GPS module should be accurate in order to provide accurate coordinates for the accurate location for it to give information to microcontroller by sending appropriate commands to display the current location for which the passenger or operator decided to stop to that location ,then he or she will push the button to buzzer to inform the bus operator to stop the bus.
