AI Driven Network Level Traffic Prediction and Incident Management Platform

Abstract

This technology family comprises an integrated suite of computer-implemented systems and methods for real-time traffic prediction, incident management, and network-level control in freeway-arterial corridors. The platform ingests heterogeneous detector data, represents the transportation network as a graph, and applies spatio-temporal artificial intelligence models to forecast near-term traffic states under both routine and incident conditions. Building on these predictions, the system enables automated evaluation, ranking, and selection of incident response strategies - ranging from operational control deployment to coordinated rerouting and signal timing adjustments - using consistent, network-level performance measures. Simulation is leveraged offline to enhance model training and robustness but is removed from real-time operations, enabling low-latency, scalable, and defensible decision support for integrated corridor management.

Technical Details

2025-093-01: Traffic State Prediction and Incident Management with GCN-LSTM Models 

This UCF invention provides a real-time operational platform that continuously ingests live detector, incident, weather, and contextual data to predict short-horizon traffic states across freeway-arterial networks. The system represents the corridor as a graph and applies a spatio-temporal predictive model to forecast traffic conditions without executing traffic simulation at run time. Predicted states are used to support immediate incident management actions, and selected strategies can be deployed to traffic field devices, enabling closed-loop, AI-driven traffic operations.

2025-093-02: Synthetic Data Generation for Traffic Models

This UCF invention focuses on robust learning and comparison of incident response strategies by combining real detector data with large libraries of synthetically generated incident scenarios. A graph-based spatio-temporal model is trained offline using simulation-derived scenarios spanning multiple incident locations, durations, severities, and demand levels. During operations, the trained model predicts network traffic states for candidate strategies and evaluates them using network performance measures, enabling scalable, simulation-free strategy selection even for rare or extreme incident conditions.

2025-093-03: Incident-Conditioned Graph Learning for Network-Level Traffic Control

This UCF invention extends predictive traffic modeling by explicitly conditioning forecasts on coordinated control actions, including rerouting options, diversion percentages, and traffic signal timing plan changes. Incident attributes and control decisions are encoded as first-class model inputs, allowing the system to predict how alternative control combinations will affect network-level performance. Strategies are enumerated, evaluated using a uniform performance metric (e.g., total delay), and ranked to support auditable, data-driven control decisions for integrated freeway-arterial incident management.
