Embodiment 1

[0062] Embodiment 1: limited subset tree data structure: this tree data structure comprises the following parts: (1) sub-data frame node, descendant sub-data frame node: the next layer of direct data frame node of data frame node is this data frame A sub-data frame node of a node; a sub-data frame node and all sub-data frame nodes of a sub-data frame node are descendant sub-data frame nodes of the data frame node. exist figure 1 Among them, data frame node A is the root data frame node, B, C, and D are sub-data frame nodes of A, and E, F, K, and L are all descendant sub-data frame nodes of B. (2) Parent data frame node, ancestor data frame node: the parent data frame node is the direct data frame node on the layer above the data frame node; the ancestor data frame node is all data on the path from the data frame node to the root data frame node frame node. (3) Degree of a data frame node: the number of sub-data frame nodes of a data frame node is the degree of the data frame...

Abstract

The invention discloses a multi-way tree data storage system and method for traffic information application. The multi-way tree data storage system comprises a root data frame node module and a plurality of layers of data frame node modules, the root data frame node module is used for storing intelligent traffic application scene data of the intelligent traffic system; the data frame node module is used for constructing a deep decatree finite subset model and a data storage system by adding feature values in front of root data nodes according to the root data nodes of the intelligent traffic application scene data, performing readable storage format expression on the intelligent traffic application scene data through the deep decatree finite subset model, and storing the intelligent traffic application scene data in the data storage system, and used for describing entity dynamic behaviors of intelligent traffic application scene data. According to the method and the system, the data collected by the intelligent traffic system is effectively collected, the source tracing and management of the data are facilitated, and the storage space is saved for the operation of the intelligent traffic system.

Description

technical field [0001] The invention belongs to the field of data storage, and relates to a multi-fork tree data storage system and method for traffic information applications. Background technique [0002] Facing the development trend of globalization and informatization in today's world, traditional transportation technology and means can no longer meet the requirements of economic and social development. The intelligent transportation system is an inevitable choice for the development of the transportation industry and a revolution in the transportation industry. Through the effective integration and application of advanced information technology, communication technology, control technology, sensor technology, computer technology and system synthesis technology, the interaction between people, vehicles and roads can be presented in a new way, thereby realizing real-time , Accurate, efficient, safe and energy-saving goals. [0003] Traffic safety, traffic congestion and...
