The calculations are based on previously observed connections between accident and speed. The calculations are made at two different levels of the improved obedience. The first level means that for those roads where today more than 20 percent of the drivers exceed the speed limits, exactly 20 percent will continue exceeding them. For those roads where less than 20 percent exceed the limits nothing will be changed. The second level means that at most 5 percent of the drivers will exceed the speed limits. The results of the calculations show that for rural roads the accident reductions will be 10 and 15 percent for the two levels. The number of injured persons will decrease by 15 and 20 percent respectively and the number of killed persons by 20 and 25 percent respectively. That is approximately 100 and 150 fewer killed persons each year. The calculations for urban areas show that the number of accidents will decrease by 5 and 10 percent respectively for the two levels. The number of injured persons will decrease by 10 and 15 percent respectively and the number of killed persons by 10 and 20 percent respectively. This means 50-100 fewer killed persons each year. However, the calculations for urban areas are very rough.
