Title: A Prospective Application of Artificial Intelligence in CAV Operations
Speaker: Dr. Samuel Labi and Dr. Sikai (Sky) Chen
Date: Friday, February 25, 2022
SYNOPSIS
Rapid advances in artificial intelligence and machine learning (AI/ML) offer unprecedented opportunities for improving the operations of connected and autonomous vehicles (CAVs) in a traffic stream that also includes human driven vehicles. This presentation first discusses recent developments in vehicle automation with mixed traffic streams. The challenges and opportunities associated with AI/ML algorithm development and application for CAV operations will be identified. These include leveraging real-time data using AI/ML to improve safety, mobility, and efficiency, and to offer the capability to respond rapidly to changing traffic environments. In addition, the presentation will discuss AI/ML cooperative control algorithms for multi-agent systems that consider dynamic interactions between heterogeneous system users (e.g., human drivers, connected and/or automated vehicles). Results from extensive simulation experiments will be presented to demonstrate the effectiveness of such cooperative control innovations. Insights from this research can provide guidance to CAV manufacturers and transport agencies regarding infrastructure investments specifically for CAV operations.
