Three-dimensional intelligent transportation junction passenger flow time-space analysis and prediction system

Abstract

The invention provides a three-dimensional intelligent transportation junction passenger flow time-space analysis and prediction system which is aimed at the characteristics of passenger flow of a transportation junction. The three-dimensional intelligent transportation junction passenger flow time-space analysis and prediction system comprises a multi-source data layer, a data base layer and a functional module layer, wherein the functional module layer comprises a three-dimensional geographic information system (GIS) basic function module, a real-time traffic status analysis and release module, a transportation junction real-time traffic circle analysis and release module, a transportation junction passenger flow time-space distribution analysis and release module and a transportation junction passenger flow statistics and prediction analysis and release module. The real-time traffic status analysis and release module, the transportation junction real-time traffic circle analysis and release module, the transportation junction passenger flow time-space distribution analysis and release module and the transportation junction passenger flow statistics and prediction analysis and release module are all connected with the three-dimensional GIS basic function module. The three-dimensional intelligent transportation junction passenger flow time-space analysis and prediction system can achieve time-space analysis and three-dimensional visualization display for multi-source real-time dynamic traffic information aiming at the transportation junction.

Description

technical field [0001] The invention relates to the technical field of geospatial information systems, in particular to a three-dimensional intelligent transportation hub passenger flow spatiotemporal analysis and prediction system. Background technique [0002] At present, the management of transportation hubs lacks comprehensive management and analysis of multi-source dynamic traffic information, lacks in-depth research and application on the temporal and spatial distribution of passenger flow in transportation hubs and the statistics and prediction of short-term passenger flow patterns in transportation hubs, and lacks the spatial-temporal analysis of passenger flow in transportation hubs in 3D urban scenes. Dynamic visualization in . Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a three-dimensional intelligent traffic hub passenger flow spatio-temporal analysis and prediction system, which is character...
