One frequent cause of accidents in road is the speed of movement and adaptation conditions with circumstances of the road. For determination of speed is used the graphic-analytical method which based in maintaining the quantity of movement of the vehicles before and after the collision. This method takes into account several factors such as: measures of vehicles involved in the accident, angle between the directions of movements of the vehicles before and after the collision, the displacement distance of vehicle after the collision. Results obtained with graphicalanalytical method are compared with software method - through PC Crash software. Keywords: Velocity, Vehicle, Road, Angle, Distance, Collision, Simulations. 1. INTRODUCTION Determination of velocities of motion of vehicles participating in the accident constitutes the most important analysis in the delivery of final results to finding the cause of truly accident. Implementation of graphical –analytical method for determination of speed of vehicle in the case of accident is treated for three different cases of accidents. In each of the accidents have been involved two vehicles with different technical features. Technical characteristics of vehicles involved in the accidents which have been subjected to treatment in this paper and the road conditions which are causing accidents are presented in Table1. 69
