1.ABSTRACT: An emergency is a deviation from planned or expected behavior or a course of event that endangers or adversely affects people. When an auto crash occurs suddenly, the reaction of the emergency services now becomes a race between life and death. Today, wireless innovation has tilted the odds in favor of success like never before. Before, the people in the emergency services had little more to rely upon than raw courage. Now the world of wireless has inspired an entirely new way of managing and minimizing the death rate due to auto crash.

2.OBJECTIVE: Security in travel is primary concern for everyone. The scene of a fatal accident is always a theater where man and technology face the ultimate test. Whether the emergency is fire, earthquake or flood, relief or needed medical attention in this case, the stakes are always high. Indeed, wireless communications has become extremely important in emergency response.

4.METHODOLOGY: This project is developed to provide a information about the accident on highways to the nearest police station or tollgate. The main modules in this project are Piezo Sensor, ARM controller unit with LCD display and XBee. The transmitter will be there in the vehicle and the receiver will be there in the tollgate, police station. The transmitter module has accident detection Sensor as a input, the sensor here used is Piezo sensor, which is used to detect the accidents on highways or anywhere.

If PIR sensor got input means that indicates the accident has happened, and that sensed signal will be send to the ARM controller, then the ARM controller analyses the signal and indicates the accident has happened via LCD display. And the same information will be transmitted to the receiver via XBee and that will displayed on receiver LCD display and alarm will be turned ON to indicate there is an emergency . Then the police force or tollgate people will take appropriate action based on the information received at the receiver end.

5.ADVANTAGES AND DISADVANTAGES: All the components required are easily available. It is accurate [Errors are nullified] & precise as it is Digital. Manual errors can be avoided to some extent. Easy to use. Secure and reliable communication. Leading edge technology that meets today's and tomorrow's needs.   DISADVANTAGES: One time investment cost. It has to be planted throughout the area.

6.APPLICATIONS: This project can be implemented on Highways. Restricted zones. Wherever security and safety is needed there we can implement this project.

7. CONCLUSION: The proposed Accident informer on highways to the nearest tollgate or police station based on ARM7 and XBee has been implemented successfully and is tested on hardware. Experimental results verify the effective developed operation. This System is designed to provide the continuous information about the highways whether everything is fine or some accident has happened.
