CARPAL: Confidence-Aware Intent Recognition for Parallel Autonomy

RA-L 2021

Predicting driver intentions is a difficult and crucial task for advanced driver assistance systems. Traditional confidence measures on predictions often ignore the way predicted trajectories affect downstream decisions for safe driving. In this letter, we propose a novel multi-task intent recogniti

DiversityGAN: Diversity-Aware Vehicle Motion Prediction via Latent Semantic Sampling

RA-L 2020

Vehicle trajectory prediction is crucial for autonomous driving and advanced driver assistant systems. While existing approaches may sample from a predicted distribution of vehicle trajectories, they lack the ability to explore it - a key ability for evaluating safety from a planning and verificatio

Probabilistic Risk Metrics for Navigating Occluded Intersections

RA-L 2019

Among traffic accidents in the USA, 23% of fatal and 32% of non-fatal incidents occurred at intersections. For driver assistance systems, intersection navigation remains a difficult problem that is critically important to increasing driver safety. In this letter, we examine how to navigate an unsign

Uncertainty-Aware Driver Trajectory Prediction at Urban Intersections

ICRA 2019poster

Predicting the motion of a driver’s vehicle is crucial for advanced driving systems, enabling detection of potential risks towards shared control between the driver and automation systems. In this paper, we propose a variational neural network approach that predicts future driver trajectory distribu…

A Multi-Camera Deep Neural Network for Detecting Elevated Alertness in Drivers

ICASSP 2018accepted

We present a system for the detection of elevated levels of driver alertness in driver-facing video captured from multiple viewpoints. This problem is important in automotive safety as a helpful feedback signal to determine driver engagement and as a means of automatically flagging anomalous driving…
