Mathematical modeling and optimization of traffic control through the use of sensors detect the passing cars and information devices

The paper considers that the most effective measure to reduce the number of road accidents when overtaking in areas with limited visibility is timely information about drivers driving conditions and the lack of an oncoming car within the danger zone. More reliable results give light boards included automatically when the car passes the corresponding sensor. In this light boards issued information must be obtained by the driver at such a distance from the places of concentration of traffic accidents in which the driver received it, would be able to freely make a particular maneuver. To determine this distance, we used the method of calculating the path of overtaking. Analysis of the various options the traffic situation, taking place on the road with an unsecured appearance, shows that the most disadvantaged will be the following: one of the first bands moving slow-moving car, followed by a time interval of 3 - speedboat driver who wishes to overtake; in the opposite lane at the expiration of 3 from the moment of the passage of low-speed vehicle-speed sensor moves. A scheme for the organization and regulation of traffic on road sections with unsecured visibility with in the power of information devices. Information that warn drivers about traffic conditions on the road with limited visibility, set on the way to a dangerous site from both directions at a distance of visibility is not less than 400 m, and traffic does not exceed 400 authors / h per lane. The economic effect of the introduction of information devices is achieved by reducing the number of traffic accidents on the road with limited visibility in plan and profile, as well as by increasing the Flow rate of road traffic.
