Abstract
Highway curve is prone sections accidents, this paper studies the curve road traffic safety situation based traffic safety evaluation in curves, and it uses the vehicle lateral stability to analyze curve road traffic safety features. It discusses TruckSim and Simulink co-simulation problems and establishes TruckSim vehicle simulation model, Vehicle simulation model is established in TruckSim, though the evaluation is designed in Simulink. Geometry radius curve indicators of the current specification limit road for alignment design is analyzed and verifies the reasonableness by co-simulation. The simulation results show that it is very beneficial to use a larger bend radius for road safety under conditions permit. Drivers only need to slightly adjust the steering angle so that the vehicle can pass the curve sections in larger bend radius, it not only reduces the driver’s driving strength, but also avoids the risk of vehicle skidding or roll. The results provide a reference for future vehicle safety and road safety designs.
