Automatic Speed Reduction to Avoid Accidents
International Journal for Research in Applied Science and Engineering Technology, 2021 Abstract: We analyse the automatic braking system to reduce the speed automatically to avoid the panic action of automobiles. Stop the vehicle when it is in the accidental zone, we applied the velocity calculation according to the weight of the body which can reach to required velocity state to avoid the accident.
