Artificial Intelligence and Traffic Analysis | SDState Research

Introduction

Traffic incidents causing delays on busy highways and freeways present significant challenges for commuters and the economy. Annually, the U.S. incurs an estimated $ 87 billion loss due to traffic congestion and delays, affecting millions of Americans who spend countless hours stranded in traffic.

Kaian Fu, an assistant professor in South Dakota State University's McFadden Department of Electrical Engineering and Computer Science, is tackling this issue through his research in machine learning, graph neural networks, and artificial intelligence (AI). Fu has been focusing on employing AI to analyze traffic patterns and speed data, ultimately aiming to create predictive solutions that can help mitigate traffic congestion and delays.

Fu's work seeks to bridge theoretical computer science methods with real-world applications in traffic management. By incorporating vast amounts of traffic data gathered through the deployment of speed sensors, he utilizes graph neural networks to forecast both the duration of traffic incidents and the time it takes for a highway to clear from congestion. He explains, "We can make use of those documents and also historical traffic sensor data all together to be the input of a large model."

His innovative Traffic Incident Duration Prediction Model serves as a novel technique for predicting traffic delay times, promising to be especially beneficial for State Departments of Transportation. Moreover, Fu envisions that this research could later assist in the operation of autonomous trucks and cars.

With new funding from the National Science Foundation, Fu plans to leverage his previous work to deepen the understanding of cascading traffic congestion. He believes the potential applications of graph neural networks extend beyond traffic analysis, potentially impacting fields such as meteorology, precision agriculture, and healthcare.

Fu expresses his enthusiasm: "It's pretty exciting, and as you hear, we have a good high-performance cluster and good resources for us to proceed further in that direction."
