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 if there was a mechanism to alert the drivers 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 prime aim of our 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 many lives.
INTRODUCTION
As India sees a sharp rise in sale of personal vehicles, it is witness to another unfortunate rise, in number of deaths in road mishaps — around 1,05,000 every year, reports World Health Organisation in its report on “Decade of Action for Road Safety 2011-2020” . By using Bluetooth technology this number can be decreased. Bluetooth is a short-range radio link intended to replace the cable(s) connecting portable and/or fixed electronic devices. Key features are robustness, low complexity, low power and low cost. At a given point of time, Bluetooth devices can communicate with eight other similar devices. Thus 8 cars having Bluetooth enabled can communicate with each other within a distance of 100 meters. The range is dependent 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. We can use this feature of Bluetooth to avoid accidents, as any car comes closer to another than the specified distance, the driver will be alarmed about the same and the speed of the car will be decreased only if the speed of the car or any other in the radius of 10 m is more than 40 km ph. If the speed is less, then the driver will only be indicated about the nearby cars.
