Scalable and Customizable Intent Inference and Motion Planning for Socially-Adept Autonomous Vehicles

Project Summary

The overall objective of this project is to allow future autonomous vehicles to interact with multiple surrounding vehicles in a safe and socially-adept manner. This objective will be achieved by developing a novel algorithm framework for an autonomous vehicle to anticipate other vehicles’ behavior and customize its motion according to the local driving culture.

This project aims at answering two fundamental research questions: 1) what formalisms of intent inference and motion planning are capable of creating socially-adept motions, and 2) what embodiment of these formalisms can achieve scalability for multi-vehicle interactions and customizability for changing driving cultures?

To answer these questions, the research team will pursue the following three goals. First, the project team will build a Bayesian game model to represent vehicle interactions, and develop mechanistic intent inference and motion planning policies. Second, a message passing neural network will be developed to enable scalable intent inference and motion prediction of multiple surrounding vehicles. Third, a social attention mechanism will be developed that allows an autonomous vehicle to actively prioritize its various control considerations, e.g., safety and courtesy towards the surrounding vehicles.
