    Abstract
  • The design of super-speed highways should consider the minimum radius parameters of circular curves that ensures the safety of vehicles operating at a high speed. In this paper, a reliability theory is proposed, and a mechanical model is developed in order to study an appropriate radius of circular curves, which will ensure that the vehicles running over the curves will not create any lateral slip. Based on this principle, the radius of circular curves is analyzed, and a reliability function is proposed. In the proposed reliability function, a number of parameters are computed and analyzed, including the vehicle speed, friction coefficient of the transverse surface, superelevation, etc. Under the design speed of 100, 120, 140 and 160 km/h, the minimum radius of the circular curve is calculated and rounded. A Monte Carlo simulation method is used to calculate the failure probability of the minimum radius corresponding to each design speed. Combined with psychological tolerance of the public, a reliability design for the radius of circle curve at each design speed should ensure the failure probability is less than 0.01%. The recommended value of the minimum radius of circular curve at each design speed is 920, 1 000, 1 100 and 1 220 m under a condition of wet pavement; The minimum radius of circular curve is 1 380, 1 400, 1 420 and 1 450 m under a condition of snow-covered pavement. Study results show that in the sections with high accident rate, the minimum failure probability corresponding to the radius of circular curve for each segment is 0.019 5%. It is greater than the failure probability of 0.01% for the minimum radius of circular curve. The safety level of super-speed highway is higher than current standards when the radius of circular curve is designed with the failure probability of 0.01%.
