The invention relates to the technical field of traffic management, in particular to a road network object interaction state updating method and system based on digital twinning and a storage medium. According to the method, firstly, data acquisition is performed on a road network object, and then an importance level is determined for the road network object by adopting a scoring function according to the acquired data. The scoring function integrates factors such as traffic flow, geographic position, historical emergency frequency, accident frequency and traffic mobility. And performing weighted integration according to the importance level, the data acquisition capability, the current traffic state and the road network object state of the road network object so as to determine the real-time updating frequency of the road network object. And finally, updating the state of the road network object in real time according to the determined updating frequency. According to the method, the state of the road network object can be updated more accurately and efficiently in real time, the intelligent level of traffic management is improved, and the real-time traffic information requirements of different users are met.

    本发明涉及交通管理技术领域,尤其是基于数字孪生的路网对象交互状态更新方法、系统及存储介质。该方法首先对路网对象进行数据采集,然后根据采集到的数据采用评分函数为路网对象确定一个重要性等级。评分函数综合了交通流量、地理位置、历史紧急事件频率、事故频率和交通流动性等因素。然后根据路网对象的重要性等级、数据采集能力、当前交通状态及路网对象状态进行加权综合,以确定路网对象的实时更新频率。最后,按照所确定的更新频率,实时更新路网对象的状态。这种方法能够更加准确和高效地实时更新路网对象状态,提高交通管理的智能化水平,并满足不同用户的实时交通信息需求。
