CONTENTS Abstract Objectives Block diagram Methodology Advantages & disadvantages Applications Conclusion

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: This project we can operate Easily . Compare to other high end techniques like image detection systems at the road side. It is low cost. This project also helps to avoid accidents between vehicles, pedestrians  

DISADVANTAGES: One time investment cost

6.APPLICATIONS: Automatic vehicle braking by detecting Objects in front Vehicle. We can implement this project for Driver assistance. 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.
