Abstract:

 Every life that alive in this universe likes to enjoy the beauty in the nature. In this human beings also one kind. Towards achieving these enjoyments human beings invented & created the vehicles. But actually what happens, they are satisfying their needs by using these, but also suffering with accidents and losing valuable lives & property due to rash driving of drivers especially in highly populated regions.

               So to avoid rash driving and to prevent loosing of valuable property we need some safety systems in the vehicles. We can make this true by using sensors and other electronic components. But those have more cost which causes increase in cost of the vehicle. With out using those electronic components also we can achieve this by using mechanical arrangements. To achieve this I designed a simple mechanical system for providing safety, for avoiding rash driving in highly populated regions.

               I designed this by assuming that driver will apply the brake for more no of times in highly populated regions. Depending on these no of brake movements the system will control the maximum speed limit of the vehicle. Lower limit of the vehicle will be the same. If the no of brake applications are more, then the upper limit of the speed of the vehicle will be decreased proportionately.

                So by providing speed breakers in highly populated regions like school zones, in village’s side by the high ways we can reduce the speed of the vehicle (Lorries, autos) to avoid rash driving or to decrease effect of the accidents.
