Embodiment Construction

[0036] Such as figure 1 As shown, the data preprocessing module defines the visual data structure "fingerprint" and the corresponding interface used in the traffic data visual monitoring and analysis system, and also provides the necessary I / O operation interface, the user can conveniently read from the file Read original traffic data from databases, databases, and network streams, and convert them into abstract structures such as tables, graphs, and trees. The visualization module contains two parts, visualization data processing and layout processing. Visual data processing will add corresponding geometric information fields from the abstract data elements defined in the data preprocessing module to maintain the size, position and other information of visual elements; layout processing uses layout algorithms to generate geometric information and set it to the visual data geometric information domain. Such as figure 1The present invention as shown provides three different ...

Abstract

The invention relates to a high-efficiency visible monitoring analysis system for large-scale traffic data. The system is mainly based on a visible 'fingerprint' data model previously proposed by an inventor; the collected original traffic data is converted into the visible 'fingerprint' data model through a data conversion module under large-scale real-time data flow; and complex abstract conceptions such as periodic flow changes, track exceptions and hidden data errors in the traffic data can be visualized into simple and intuitional visual effects so as to provide automatic detection and analysis of city hot spot regions based on density, road traffic flow analysis based on historical traffic flow dynamic properties and real-time monitoring analysis of the traffic track exceptions based on vehicle historical data and statistic information for a user. The periodical flow change properties in the large-scale traffic data are analyzed in real time based on the historical data and the statistic information to find hidden rules and errors so as to provide analysis and support for the decision of the user. Therefore, the convenience is provided for an analyzer to quickly understand the data and the information, the analysis threshold is reduced, the application range is expanded, and the analysis efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to an efficient visual monitoring and analysis system for large-scale traffic data. The system is based on the visual data model "fingerprint". While supporting the real-time display and monitoring of flow data, it visualizes some complex abstract concepts in traffic data, such as periodic changes in traffic, abnormal trajectory and hidden data errors, as The simple and intuitive visual effect is convenient for analysts to quickly understand and compare, thereby lowering the analysis threshold, expanding the scope of application, and improving analysis efficiency and accuracy. Background technique [0002] In recent years, the widespread use of GPS devices, mobile communication devices, and various sensor devices around the world has brought about changes in traditional data collection. With the diversification and miniaturization of various sensing devices and the rapid development of wireless sensor network technology, research...
