[Ongoing problems of road signs in transportation control]

The diagnosis and evaluation of causes of traffic accidents frequently calls for effective mutual collaboration of forensic medical officers and transport psychologists. Both scientific disciplines participate in prevention of traffic injuries as regards theoretical arguments and practical provisions. The Bratislava Institute of Forensic Medicine, based on many years of professional and practical experience, participates in the elaboration of principles of risk-free transport of urban and non-urban traffic as well as in preventive provisions and suggestions for conditions of traffic the field. Due to social and economic changes they will be faced in future with more complicated traffic problems/safety of pedestrians--children, old people. In transport man adapts, due to biological laws, with greater difficulties to technical signs of controlled traffic which assumes rapid, immediate and inevitable reactions. Transport safety cannot be resolved unless within prevention a radical solution will be found for the risk of alcoholism, toxicomania, ever increasing speed of vehicles and greater traffic density.
