TL;DR

This paper introduces the colliding reciprocal dance problem, a situation where incompatible interactions between mobile agents can lead to deadlock or collision, and proposes a mitigation strategy demonstrated in automotive safety systems.

Contribution

It defines the colliding reciprocal dance problem, analyzes its causes, and presents a mitigation approach applicable to automotive active safety systems.

Findings

Mitigation strategy reduces collision risk in reciprocal dance scenarios.

Applicable to automotive active safety systems.

Improves safety without reducing system flexibility.

Abstract

A reciprocal dance occurs when two mobile agents attempt to pass each other but incompatible interaction models result in repeated attempts to take mutually blocking actions. Often, such a situation simply results in deadlock. But in systems with significant inertial constraints, it can result in collision. This abstract presents this colliding variant of the reciprocal dance, how it arises, and a mitigation strategy that can improve safety without sacrificing flexibility. A demonstration of the concept is provided in the context of automotive active safety.
