Influence of Road Conditions on Traffic Safety

We consider estimation of the impact of road conditions on traffic safety on the basis of the theory of the interaction of the driver with traffic environment. It is shown that the number of accidents is influenced by factors related to the environment, traffic, road users and the vehicle. The mismatch between the Therefore, when addressing the issue of improving traffic safety, it is necessary to pay attention to research methods, studying the patterns of behavior of the driver and allows to assess the impact of road conditions on the probability of an accident. On the basis of the conducted studies was established the relationship between the elements of road conditions and indicators of the functional status of the driver. Optimal speed for various road conditions is established. The optimality criterion is the reliability of the driver's activity. The obtained results are the basis for the development of measures aimed at optimizing the elements of the environment movement, as well as practical methods of assessing damage from an accident in a changing operating conditions.
