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 pedestrianto-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
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.
