THE INFLUENCE OF THE LATERAL ACCELERATION ON VEHICLE VELOCITY MOVING ON CURVED ROAD

The movement of the vehicle in a curve related to the construction of the road is expressed through the influence of the radius of the curve and the transversal inclination of the road. Two of these parameters are fixed quantities ever since the projection and then construction phase of the road. During the vehicle's movement in the curve, their influence is shown through the critical slide velocity. This critical velocity is defined from the influence of the centrifugal force therefore lateral acceleration. Vehicle velocity is lower at the end of curve than in entrance, even when the driver is trying to keep constant velocity of vehicle, due to changes of lateral acceleration.
