ABSTRACT
In the current scenario the world is plagued by accidents which are primarily due to human errors in judgment and hence thousands of lives are lost. These accidents can be avoided if only there was a mechanism to alert the driver of approaching danger. This can be done by monitoring the distance between nearby cars and alerting the driver whenever the distance becomes too short. This is precisely the aim of this paper. In this paper we propose the use of Bluetooth Technology by which we can check the speed of the car whenever it comes dangerously close to any other vehicle up front, thereby saving very many lives.
INTRODUCTION
Since Bluetooth devices are capable of communicating with eight other devices simultaneously we can monitor and check the speeds of up to eight cars simultaneously, thus preventing accidents. Thus if we have two Bluetooth enabled devices in two cars the devices automatically communicate with each other when they come in the range of up to 100 meters of each other. The range is dependant on the power class of the product. Power transmission rates vary in many Bluetooth devices depending upon the power saving features available in a particular unit, bandwidth requirements, transmission distance. The statistics of road accidents is tremendous and highlights the need for such a system. The following is a statistic on the number of road accidents occurring each year.

OPERATION:
Because of traveling at high speeds there is a possibility of having accident. The figure 2 shows that when two cars or more come within the distance of 10 km at high speeds there is a possibility of having accidents. The Bluetooth radio is a short distance, low power radio operating in the unlicensed spectrum of 2.4 GHz and using a nominal antenna power of 20 dBm.
AUTOMTIC BRAKE SYSTEM:
The automatic brake system is the next generation braking system for controlling the speed of the car. On receiving the control signal from the traveling car the computer inside the car manipulates the signal and gives control signal to the braking system.
There are four main components to an automatic braking system:
REPRESENTATION OF OUR IDEA:
In the figure 7 when car A and car B come within the range of 100m both the Bluetooth devices get enabled and if any one of the car comes too fast then the bluetooth device sends a warning signal to the other car and it processes the signal and gives it to the automatic braking system.
CONCLUSION:
The Bluetooth technology is being widely adopted by the Industry leaders. The possibility for new applications is very exciting with this versatile technology. It provides a simple, logical answer to all the Problems which is built a single common radio into every mobile computer ,then neither do companies have to worry about WAN, nor do
communication companies need to worry about building external cables.
The Bluetooth communication device will thus be a small, low powered radio in a chip that will talk to other Bluetooth enabled products. Bluetooth has been designed to solve a number of connectivity problems experienced by the mobile workers & consumers. Thus, this technology helps make the electronic devices more user friendly and helps address various
