TOPIC 3. CONTENTS OF THE TRAFFIC SAFETY AUDIT AT THE STAGE OF HIGHWAY DESIGN (8 hours)

Classification of highways. Technical regulations and approaches to the classification of roads intended for the movement of automobile rolling stock. Roads of state importance (international, national, regional). Roads of local significance of Ukraine (territorial, district, rural). An important parameter when planning the development of the road network is the composition of the prospective traffic flow.

Determination of prospective intensity and speed of movement. Methods of extrapolation; balance methods; model methods of traffic intensity forecasting. Iterative process of determining the speed of movement. Coefficients of reduction of traffic speed in areas adjacent to the centers of populated areas. Algorithm for calculating traffic intensity. Determination of the composition of the traffic flow. Forming the operation of motor vehicles with a division by type into passenger cars, buses and trucks. Road visibility parameters.
