This invention discloses an intelligent traffic management system based on spatiotemporal sequence features, belonging to the field of intelligent traffic management technology. The system includes a data fusion and spatiotemporal sequence management module for real-time acquisition of multi-dimensional traffic data and data preprocessing; a spatiotemporal causal chain modeling and source analysis module for modeling spatiotemporal causal chains, assessing the causal strength of road events, and implementing causal control decisions; a traffic state prediction and intelligent control module for predicting traffic states and comprehensively analyzing traffic control needs; an anomaly detection and adaptive optimization module for assessing traffic anomalies and implementing adaptive traffic control measures; and an intelligent feedback and self-evolution module for comprehensively analyzing control benefit feedback and automatically implementing optimization strategies. This invention solves the problem of untimely traffic control in complex traffic environments where the superposition of multiple minor traffic anomalies makes it difficult to automatically perform intelligent source tracing of traffic event causal chains.

The invention relates to the technical field of traffic planning, and discloses an urban traffic optimization and planning method and system based on artificial intelligence data processing, and the method comprises the steps: collecting a time sequence perception data flow of a target intersection, and carrying out the extraction of an occupancy state tensor based on a time window, and obtaining the occupancy state tensor of the target intersection in the time window; using the occupancy mode analysis model to output occupancy mode probability distribution of the target intersection in the time window; and outputting the lane traffic capacity of the target intersection by using a lane traffic capacity calculation function which is corrected by introducing dynamic factors of a temporary parking type occupation reduction factor and a queuing type occupation delay factor, and dynamically adjusting a short-time traffic control strategy of the target intersection. According to the invention, through time sequence perception and occupation mode analysis, the temporary parking and queuing occupation modes are distinguished, and the traffic capacity of the lane is dynamically quantified and corrected, so that the short-time traffic control strategy is adjusted in real time, and refined and adaptive traffic control and optimization under complex disturbance conditions in a city are realized.

This application relates to the field of traffic scheduling technology and discloses a method and apparatus for traffic control processing of credit reporting inquiries. One method for traffic control processing of credit reporting inquiries includes: obtaining a calling mode by adapting the mode of the credit reporting inquiry period during the traffic control scheduling process; calculating the real-time traffic deviation for the real-time time window of the calling period when the calling mode is a traffic clearing mode; combining the real-time traffic deviation with steady-state deviation data for adaptive traffic control scheduling to obtain adaptive traffic control parameters; finally, sending the adaptive traffic control parameters to the calling task; and executing the calling task to realize the credit reporting inquiries from the credit reporting platform by the resource organization. This achieves dynamic adaptive traffic control during the credit reporting inquiries process, which helps the resource organization clear the credit reporting inquiries traffic.
