As in the name the Rider’s Safety Assurance System ensures the safety of the rider. This project is developed on two particular road problem. The first problem is that a bike rider does not wear a helmet while riding his or her two wheeler vehicle. This might lead to head injury when the rider comes with an accident, which could be fatal. The second problem is that the riders like teenagers and even some adults over speed in areas where speed should be minimum. This might lead to some fatal accidents, especially in school or collage areas, construction areas, etc. So to solve this two problems we have come up with a solution which is Rider’s Safety Assurance System. Firstly this project ensures that the rider can insert the key in his vehicle only if he or she has worn a helmet. This will not let the rider start his or her two-wheeler without wearing a helmet. And secondly to control the speed of two wheelers we have used the speed limit sign on the roadside. First the speed sign of a school or collage area will detect the vehicle which is passing through that road. After detecting the sigh circuit will send a signal containing the speed limit data of the load like 30kmph, 50kmph, etc. Then the vehicle will receive the data and compare it with the vehicle speed. If the vehicle speed is more than the required speed of the road then a mechanism will trigger that will not allow the rider to accelerate his bike further. This will keep the vehicle speed in range in the low speed areas like school, collage, etc. So this project will solve this two problems of not wearing helmet and over speeding. From this project, we hope that the rider and the people near him are safe and avoid accidents.
