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.
