The invention provides a road intelligent guardrail decision-making method based on digital twinning. The road intelligent guardrail decision-making method comprises the steps of S1, acquiring historical static data and historical dynamic data of an intelligent guardrail, and adding the historical static data and the historical dynamic data into a pre-constructed intelligent guardrail digital twinning model; s2, vehicle data left when vehicles on the two sides of the intelligent guardrail pass through are collected in real time, the vehicle data are divided into real-time static data and real-time dynamic data, and then the intelligent guardrail digital twin model is updated in real time; and S3, calibrating one direction of the intelligent guardrail as a d side, obtaining road condition information of the d side of the intelligent guardrail in real time, and inputting the road condition information into the intelligent guardrail digital twin model to obtain a movement adjustment probability of the intelligent guardrail towards the d side so as to assist an operator in adjusting the position of the intelligent guardrail. The method has the beneficial effects that the mobile adjustment probability can be obtained according to road condition information analysis for decision support, and the position adjustment reliability of the intelligent guardrail is ensured.

    本发明提供了一种基于数字孪生的道路智慧护栏决策方法,包括:步骤S1,获取智慧护栏的历史静态数据和历史动态数据并将历史静态数据和历史动态数据添加至预先构建的智慧护栏数字孪生模型内;步骤S2,实时采集智慧护栏两侧车辆通过时留下的车辆数据,将车辆数据划分为实时静态数据和实时动态数据后对智慧护栏数字孪生模型进行实时更新;步骤S3,针对智慧护栏标定一个方向为d侧,实时获取智慧护栏d侧的路况信息,并将路况信息输入至智慧护栏数字孪生模型内得到智慧护栏向d侧的移动调节概率,以辅助作业人员对智慧护栏进行位置调整。有益效果是本发明可以根据路况信息分析得到移动调节概率进行决策支持,并保证智慧护栏位置调整的可靠性。
