Abstract

The invention discloses a traffic time-space process modeling management method and device based on dynamic graphs and graph databases, belonging to the field of geographic information services for smart cities. The invention utilizes the advantages of dynamic graphs to effectively model and express traffic spatio-temporal processes , so as to reflect the spatiotemporal dynamics of traffic objects and the complex traffic relationship between objects; use this method to store the traffic spatiotemporal process in the Neo4j graph database, and use the Neo4j graph database to perform historical retrospect, thereby supporting the rapid inversion of the traffic spatiotemporal process; At the same time, the scalability of this storage method is very good. When there is a change, the attributes in the nodes and relationships can be directly changed, which is conducive to the in-depth analysis of the complex traffic relationships between traffic entities in the traffic space-time process in the real world, and provides information for traffic planning and facilities. The basis for construction.

Description

technical field

[0001] The invention belongs to the field of smart city geographic information service, and more particularly, relates to a traffic spatiotemporal process modeling management method and device based on a dynamic graph and a graph database. Background technique

[0002] The rapid development of society has promoted the continuous upgrading of urban transportation. Traffic modeling helps to analyze the rules of vehicle travel and provide decision support for smart transportation. Existing traffic modeling objects are mainly oriented to traffic infrastructure, such as road networks, gas stations, etc., and extensive and in-depth research is carried out based on this. However, these traffic modeling methods serving traffic infrastructure management are all static and cannot effectively express the dynamics of traffic spatiotemporal processes and the correlation between traffic objects.

[0003] The traffic spatiotemporal process is used to describe the evolution...
