Accident Detection System and Vehicle Overtaking System Using Wireless Technology
Accidents are one of the most dreaded situations in one`s life, on an average atleast one vehicular accident occur everyday around the world. It has also been observed that the most number of people die as they do not get to the hospital in time after such road accidents in highways or remote locations such as rural villages. This causes unintended loss of life.
Therefore to overcome such haphazard’s we propose to development a wireless system which will reduce this problem drastically. The system will relay wirelessly to a local police stations or hospitals, the exact location of an accident as it occurs. Therefore notifying the authorities about such an event, where they can help out the accident victims in time. Thus saving precious lives. The system/ device will consist of micro controllers, wireless communication modules and display devices to enhance user interaction and to make it easy for anyone to use.
The other benefit from this system is that it is also being used as a driver assistor for overtaking vehicles in highways. Which will reduce noise pollution and unwanted honking of horns? Therefore this project is designed to enhance the utility of electronics and telecommunication devices to assist and save human life on the go.

Accident detection System
* Block Diagram explanation :-
Accident Detection System : This is basically a mechanism which will notify the microcontroller that an accident has occurred in the vehicle. This system is just switching mechanism which has very less response time.
MICROCONTROLLER : This block consists of microcontroller ATmega16 AVR based circuit. Here microcontroller is used as the main digital signal processing system. It will control the communication module and the LCD display. Some of the features of the microcontroller include, * High-performance, Low-power AVR® 8-bit Microcontroller * 8K Bytes of In-System Self-programmable Flash program memory * 512 Bytes EEPROM
* 1K Byte Internal SRAM
* Programmable Serial USART
* Master/Slave SPI Serial Interface
* Power-on Reset and Programmable Brown-out Detection
* Active: 3.6 mA
* Idle Mode: 1.0 mA
* Power-down Mode: 0.5 μA
Communication Module : This section consists of a 2.4Ghz bluetooth spectrum transmitter/receiver module. The CC2500 is a low-cost 2.4 GHz transceiver designed for very low-power wireless applications. The circuit is intended for the 2400- 2483.5 MHz ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency band. The RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data rate up to 500 k Baud. CC2500 provides extensive hardware support for...
