The invention discloses a highway traffic data storage and retrieval method based on transverse fusion of traffic marks, which is characterized by comprising the following steps of: 1, recording a traffic record generated when a highway goes to a portal frame; step 2, constructing a point-line relationship: constructing a transverse relationship: when the passage record in the step 1 is generated, establishing a timeline chain corresponding to the passage medium on the basis of the passage mark, associating all passage records on the timeline of the passage medium by taking the passage mark of the passage medium as key information, and representing one passage record at each point; and constructing a longitudinal fusion relationship: on the basis of completion of construction of the transverse relationship, constructing a longitudinal fusion relationship for recording the passing marks and the passing records, including portal information, a record ID of the passing records generated by the portal, and the position of the passing records in the constructed transverse relationship. By using the data, the efficiency of transverse data retrieval and longitudinal data retrieval is higher in an application scene of a clearing settlement system.
本申请公开了一种基于通行标记横向融合的高速通行数据存储检索方法,其特征在于,包括以下步骤:步骤一、记录高速上门架所产生的通行记录;步骤二、点线关系构建:横向关系构建:在步骤一通行记录产生时,以通行标记为基础建立对应于通行介质的时间线链条,以通行介质的通行标识为关键信息关联该通行介质时间线上所有通行记录,每个点表示一个通行记录;纵向融合关系构建:以横向关系构建完成为基础,构建记录通行标记与通行记录的纵向融合关系,包括门架信息、门架所产生的通行记录的记录ID、以及通行记录在构建完成的横向关系的位置。使用上述数据,在清分结算系统的应用场景中,横向数据检索与纵向数据检索的效率更高。
