Many factors affect the road traffic safety, among which the most important is the human factor who contributes with as much as 85 percent. The other 15 percent falls on other factors, among which the road is one of the most important. The design elements of traffic areas that affect the road traffic safety can be divided into elements of the cross section of the road, floor plan and vertical elements. To ensure optimal traffic safety, all these elements need to be designed according to the existing technical regulations. In addition to the high quality design of new roads, the already built roads need to be controlled and, if necessary, do measures for improving the design elements. Particular attention should be paid to hazardous places on the roads, which are determined by the safety coefficient.
