Abstract

When the ramp toll plaza is set up on a horizontal curve section of the road, the current highway regulations stipulate that the design baseline of the toll plaza should adopt a chord line determined by the toll plaza length. However, this design method has many problems. This paper proposed a new solution for the situation of low operating speed before and after setting up toll stations by conducting analysis and research. At both ends of the toll plaza, according to the design speed of 20 km/h, a circular curve of no less than 20 m was added to connect the horizontal curve and the straight line of the toll plaza. Compared with the methods required by regulations, the new method simplifies design, facilitates construction, and arranges the transition area of the toll plaza reasonably. Additionally, it ensures the smooth connection between the transition section pavement and the subgrade edge, achieving a beautiful road appearance and smooth driving trajectory.
