1.ABSTRACT:

We propose a prototype pedestrian-to-vehicle communication

system which uses a cellular phone and wireless communication to

improve the safety of pedestrians. One of the effectual measures against

pedestrian-to-vehicle accidents is to make each of pedestrians and drivers

find the others and recognize the risk from out of sight and with time to

spare for avoidance of accidents. A pedestrian-to-vehicle communication

system was developed by using a cellular phone and a car navigation

system equipped with XBee and wireless communication function.

 

 

2.OBJECTIVES:

This system focuses on the vehicles inform pedestrians of their

existence. Since a very limited effort is made for pedestrian safety, we

address the issue in a concrete way. Specifically, we first formulate the

requirement on the minimum information exchange distance for allowing

pedestrians to have necessary time to perceive and react. Because the

minimum distance is a function of the positioning accuracy and the

communication range, we carry out real-world experiments and investigate

the performances using XBee Technology .

4. METHODOLOGY:

The transmitter will have the pedestrian monitoring system ,

when it detects the moment then it gives the signal to the ARM , then the

ARM will send the information to another receiving station through XBee

which is in vehicle. At the same time ARM will generate the out put that is

fed to buffer IC 4050 ,buffer stores and given to the driver IC 2003 in

driver current will amplifies and voltage will inverts with the help of

Darlington circuit of driver IC to drive the relay . Then signal is given to

the output load for indication purpose .

When ARM receives the data from the XBee, it will enable the alert

through the Buzzer in receiver side which is placed in vehicle.

5. ADVANTAGES & DISADVANTAGES:

ADVANTAGES:

1.This project we can operate Easily .

2.Compare to other high end techniques like image detection systems at the

road side.

3.It is low cost.

4. This project also helps to avoid accidents between vehicles, pedestrians 

DISADVANTAGES:

One time investment cost

6.APPLICATIONS:

1. Automatic vehicle braking by detecting Objects in front

Vehicle.

2. We can implement this project for Driver assistance.

3. we developed an application with the functionalities of

XBee communications, risk calculation, and hazard

alarming.

7.CONCLUSION: 

Wireless communications technology has a potential to support

safety of vulnerable road users by enabling information exchange between

pedestrians and vehicles. This system introduces our study on pedestrian

safety support by XBee based communications. We formulated the

requirement of the minimum information exchange for pedestrian

protection and conducted a study on the applicability of XBee based

communications system.
