摘要: 针对在弯道路段行驶车辆的安全性问题,从动力学角度出发,分析了车辆在实际道路弯道上行驶的受力情况,确定了车辆横向加速度与弯道线形参数的关系,并依据加速度干扰理论,就典型的缓-圆-缓弯道建立了由弯道曲率和弯道长度描述的横向加速度干扰模型,并通过一条二级山区公路的实际线形参数对所建立的车辆弯道行驶横向加速度干扰模型进行验证,得到了符合实际的各弯道路段行车安全性评价结果,文中给出的模型和方法为行车安全性评价提供了新的途径。

Abstract: For the traffic safety problem of the vehicles driving along the curved road, the force of the vehicles running on the actual curved road was analyzed from the perspective of the dynamics, and the relationship between the vehicle lateral acceleration and the curve alignment parameters was determined. According to the theory of acceleration interference, the lateral acceleration interference model described by the curvature and length of curved road was established for the typical slow-round-slow curved road. The proposed lateral acceleration interference model of vehicles running along curved road was validated by actual alignment parameters of a secondary mountainous highway. The safety evaluation results of vehicles driving along the curved road sections were obtained, which was in line with the actual situation. The proposed model and method provide a new way to evaluate the safety of driving.

Key words: traffic engineering, traffic safety, acceleration interference, highway alignment, model establishment
