Efficient transportation is an important factor for regional socio-economic growth. Excitations from wind loads and road motions can influence vehicle-driver behaviour in a way that may impair transportation. This is especially true in open areas such as long-span bridges. This paper investigates the influence of wind loads and floating bridge motions on bus lateral stability for the straight concept solution across Bjørnafjorden in Norway. For this investigation, an 8-degree-of-freedom model of a two-axle coach is used. The defined driver model is based on the pure pursuit path tracking method. The vehicle deviation from the path is found to increase with increasing bus speed. This deviation is significant after the vehicle enters the bridge (e.g., over 0.5 ​m for a speed of 90 ​km/h). At 108 ​km/h, the windward rear wheel loses contact, indicating the potential risk of vehicle roll-over. The mean and root-mean-square values of the handwheel steering angle increase with increasing speed, which might cause difficulty for the driver to control the vehicle. Simulation results suggest that the bus can suitably enter the bridge at a lower speed (e.g., 72 ​km/h) with the possibility of increasing the speed (up to 90 ​km/h) after approximately 2 ​km of travelled distance.

高效的运输是区域社会经济增长的重要因素。风荷载和道路运动引起的兴奋会以可能影响运输的方式影响驾驶员的行为。在大跨度桥梁等空旷地区尤其如此。对于挪威Bjørnafjorden上的直线概念解决方案，本文研究了风荷载和浮桥运动对公交车横向稳定性的影响。在此调查中，使用了两轴教练车的8自由度模型。定义的驾驶员模型基于纯追踪路径跟踪方法。发现车辆偏离路径的偏差随着总线速度的增加而增加。车辆进入桥梁后，此偏差非常大（例如，对于90 km / h的速度超过0.5 m）。在108 km / h时，迎风后轮失去接触，表示车辆翻车的潜在风险。手轮转向角的均方根值和均方根值随速度增加而增加，这可能会导致驾驶员难以控制车辆。仿真结果表明，公交车可以以较低的速度（例如72 km / h）适当地进入桥梁，并且有可能在行驶大约2 km后增加速度（最高90 km / h）。
