In the description of different countermeasures it is shown that there are insufficient reliable data from which the effects of possible countermeasures for preventing injury to pedestrians, cyclists and moped drivers can be determined. Only an estimate can therefore be made from available data. If the different countermeasures are divided into measures for the car, the two-wheeled vehicle driver, the human being or the environment then it is shown that the greatest reduction of injury can be expected from measures for the car, the environment and the human being. The decrease of the speed of collision will have the greatest effect. The application of a well designed energy absorbing layer on the car will cause a relatively big reduction by influencing the kinematics. With an unchanged policy of driving speeds, and therefore also collision speeds, a saving of 20 to 50% of the injured or fatally injured pedestrians and cyclists in collisions with a car can be expected. Of the total number of killed or registered injured pedestrians and cyclists this will mean a reduction of 10 to 30%.
