Among traffic accidents in the US, 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 paper, we examine how to navigate an unsignalized intersection safely under occlusions and faulty perception. We propose a real-time, probabilistic, risk assessment for parallel autonomy control applications for occluded intersection scenarios. The algorithms are implemented on real hardware and are deployed in a variety of turning and merging topologies. We show phenomena that establish go/no-go decisions, augment acceleration through an intersection and encourage nudging behaviors toward intersections.

INTRODUCTION I NTERSECTIONS present one of the most challenging driving scenarios because a vehicle must interact with others to navigate safely. In 2016, 23% of fatal and 32% of non-fatal traffic incidents in the U.S. occurred at intersections 1. Recent advances in robotic perception and control routines promise to enhance the safety of passengers on the road through fully autonomous cars or by augmenting the human with advanced driver assistance systems (ADAS). However, reasoning about intersections remains a major challenge. Perception systems may fail to detect other vehicles as a consequence of occluded views. Causes of these occlusions may stem from cross-traffic behavior, buildings or road geometries that cause poor visibility [2]. As a consequence, tracking and detecting other road objects may fail in unpredictable ways. New models must account for the resulting uncertainty and risk while ensuring robustness to imperfect perception and remaining computationally efficient.
