The invention provides an HMM algorithm passenger transport channel flow matching technology based on a road network and total element information. The technology comprises the following steps: S1, data preparation: collecting road network information, traffic flow data and total element information of a passenger transport channel; s2, model training: performing model training on the passenger transport channel by using an HMM algorithm, and establishing a state space, an observation space and a transition probability matrix of an HMM model according to training data; and S3, generating an observation sequence: generating the observation sequence according to the total element information of the passenger transport channel and the road network topology, and representing the state change of the passenger transport channel. The invention provides an HMM algorithm passenger transport channel flow matching technology based on a road network and total element information, and solves the problems that a rule-based method depends on priori knowledge and manually set rules and lacks flexibility and adaptivity, and for a complex passenger transport channel network, the rules may not cover all conditions, resulting in an inaccurate matching result.

    本发明提出了基于路网和全要素信息的HMM算法客运通道流量匹配技术,包括以下步骤:S1、数据准备:收集客运通道的路网信息、交通流量数据和全要素信息;S2、模型训练:使用HMM算法对客运通道进行模型训练,根据训练数据,建立HMM模型的状态空间、观测空间和转移概率矩阵;S3、观测序列生成:根据客运通道的全要素信息和路网拓扑,生成观测序列,表示客运通道的状态变化。本发明提出了基于路网和全要素信息的HMM算法客运通道流量匹配技术,解决了基于规则的方法依赖于先验知识和人工设定的规则,缺乏灵活性和自适应性,对于复杂的客运通道网络,规则可能无法覆盖所有情况,导致匹配结果不准确的问题。
