Many technologies have recently made noticeable changes in several domains. This paper will shed the light on the field of transportation to improve the life quality of visually impaired persons (VIPs) using some of these technologies such as Radio Frequency identification (RFID) and wireless sensors network. Furthermore, a mechatronic system architecture and an appropriate design for its components will be proposed. This system will allow VIPs to safely catch buses with the help of an audio device and a tactile interface through a wireless communication system (Wi-Fi) between the transmitter and the receiver. VIPs will have the opportunity to get information about bus/transit stop locations and departure times or other transit schedule information. The motivation behind this project is that buses are vital in enabling blind people to participate fully in society, access to facilities and services.

CHAPTER ONE
1.0 INTRODUCTION
Public transport is the only viable mobility option to seek education, work and social connectivity for a majority of blind and visually impaired persons. They face major difficulties in independently accessing public buses since they cannot read the route number and are unsure about the physical location of the bus and its entry/exit door. Despite constantly seeking help from sighted fellow travelers, blind persons frequently miss their desired bus, are unable to reach the entry gate and frequently get hurt in the process. The possibility of these events adds to the fear and anxiety of the visually impaired traveler.
A radio-frequency based solution has been developed which consists of two modules: a mobile-like hand-held user module, and a bus module installed inside the bus. Once at a bus stop, the user presses the query button on the handheld module to obtain route numbers of the buses in vicinity. These numbers are read out to the user via a speaker / head phone in the user module. This essentially solves the first problem of helping the user know if the desired bus is there at the bus stop. Once the route number of a desired bus is read out, the user needs to select it by pressing the selection button. This triggers a voice output of the number from a speaker installed at the entry door of the bus, thereby assisting the user in orienting and navigating towards its entry. The select button can be pressed multiple times to trigger the guiding voice output from the bus. Once the select button is pressed, it activates a bulb at the driver panel thereby informing the driver about a person with special needs who wants to board his particular bus
1.1 OBJECTIVE OF THE PROJECT
The objective of this work is to design a handheld radio frequency identification device used by the blind to obtain route numbers of the buses in vicinity. This essentially solves the first problem of helping the user (the blind) know if the desired bus is there at the bus stop.
1.2 PURPOSE OF THE PROJECT
Blind persons frequently miss their desired bus, are unable to reach the entry gate and frequently get hurt in the process. The possibility of these events adds to the fear and anxiety of the visually impaired traveler. The purpose of this project is to built a device that will solve the problems of the blind when travelling.
1.3 SIGNIFICANCE OF THE PROJECT
Bus identification system for the blind project explains about concept of implementing efficient communication method for blind people. Though there are many applications like text to speech converters, cochlear implants and prosthetic limbs in the market. Using this application we provide and wireless communication system which works on radio frequency for blind people which can improve standards of bus transportation and provides easy accessing method for blind people which minimum risk.
1.4 SCOPE OF THE PROJECT
This device uses transmitter attached to bus which will transmit signals. The blind are provided with hand held device with a audio and tactile interface via radio frequency technology. This system is tested on present bus transport system. The transmitter will send details to hand held device through which the blind will understand corresponding routes details and arrival of bus. As per transmitter specifications communication between transmitter and receiver are established at 900MHZ.
1.5 APPLICATION OF THE PROJECT
In existing system there is no specific method for helping blind people for improving transport system. Blind people used to take help form other people to catch bus. In present system blind people can find solution using a communication system which will be helpful for transport department as well as blind people and also to visually impaired persons (VIPs).
1.6 LIMITATION OF THE PROJECT
- The problem of this work is that if the user lost the transmitter that will make him/her lost her way.
- It is costly
- It needs to be monitored by someone to make sure that the battery is in good condition, this is because the device will stop working if the battery is dead.
1.7 FUTURE DEVELOPMENT
Here we use one way communication between bus transmitter and hand held device. In future this project has scope for implementing duplex communication which will help bus driver to identify the blind information and vice versa. Using this method we can improve bus transport service for the blind.
1.8 PROJECT WORK ORGANISATION
The various stages involved in the development of this project have been properly put into five chapters to enhance comprehensive and concise reading. In this project thesis, the project is organized sequentially as follows:
Chapter one of this work is on the introduction to bus identification system for the blind. In this chapter, the background, significance, objective limitation and problem of bus identification system for the blind were discussed.
Chapter two is on literature review of bus identification system for the blind. In this chapter, all the literature pertaining to this work was reviewed.
Chapter three is on design methodology. In this chapter all the method involved during the design and construction were discussed.
Chapter four is on testing analysis. All testing that result accurate functionality was analyzed.
Chapter five is on conclusion, recommendation and references.
This material is a complete and well researched project material strictly for academic purposes, which has been approved by different Lecturers from different higher institutions. We make abstract and chapter one visible for everyone.
All Project Topics on this site have complete 5(five) Chapters . Each Project Material include: Abstract + Introduction + etc + Literature Review + methodology + etc + Conclusion + Recommendation + References/Bibliography.
