| Summary: | The paper presents a method of constructing the trajectory trains movement while performing turning maneuvers. On disordered crossroads where the curve radii of the plan does not meet the requirements of the movement of modern large vehicles, drivers moving along the main road, before implementing right turn maneuver forced most to reduce speed, shift into the oncoming lane, to carry out the rotation, ending it as well on the strip oncoming traffic secondary roads. If there is on this road standing in the queue for pivoting maneuver of the vehicle at the intersection traffic flow may be completely paralyzed. The probability of congestion and long-term downtime increases, if the width of the roadway secondary road is less than 6 m. Destination type radii at intersections and junctions, while the main type of rounding applied arc, which is represented by a circular curve without any additional transient curves do not meet modern conditions of movement of vehicles. It is known that when driving on different curvature of the wheel of the car moving along the trajectories of different radii and cannot describe the curve of constant radius. Overall lane (GPA) is quite complicated, as the trajectory of large vehicles requires its own study.
The paper presents the results of a study of the trajectory of motion trains when changing direction. Also, the method for determining the trajectory of movement of trains was proposed. The recommendations on the design elements of the geometric parameters of road junctions in one and different levels. |
