The invention discloses an arterial highway traffic guidance method in an Internet of Vehicles environment. The arterial highway traffic guidance method comprises the following steps: acquiring corresponding origin-destination information according to a departure request sent by a driver; constructing a road network structure chart; and dynamically inducing road vehicles in real time in a graded induction mode. According to the method, vehicles are induced from three levels of a road network, a path and a road section, and the impedance of the next level is fed back to the previous level in real time to update the impedance of the road network. Meanwhile, a new calculation method is provided for the real-time impedance function of an arterial highway, and the three factors of mutual influence of large and small vehicles on the arterial highway, impedance sudden change caused by road emergencies and intersection and steering delay are considered at the same time. By using the method, not only can the traffic operation efficiency of the arterial highway be improved, but also the accuracy of path induction is improved.

本发明公开了一种车联网环境下的干线公路交通诱导方法，包括：通过驾驶员发出的出发请求获取相应的起讫点信息；构建路网结构图；采用分级诱导的方式，对道路车辆进行实时动态诱导。本发明分别从路网、路径及路段三个层面对车辆进行诱导，并将下一级阻抗实时往上一级反馈进行路网阻抗更新。同时，本发明对干线公路实时阻抗函数，提出了新的计算方法，同时考虑了干线公路大小型车辆的相互影响，道路突发事件造成的阻抗的突变和交叉口自身及转向延误三方面因素。该方法的使用，不仅可以提高干线公路交通运行效率，还增加了路径诱导的精确性。
