Reducing Warning Errors in Driver Support with Personalized Risk Maps

TL;DR

This paper introduces a personalized risk map-based warning system for driver support that adapts alerts to individual driver behavior, significantly reducing false warnings and improving safety in driving scenarios.

Contribution

It proposes a novel personalized risk estimation approach that adapts warning signals based on driver behavior, enhancing the effectiveness of risk warnings in driver support systems.

Findings

Reduces false negative errors in warning signals

Decreases false positive errors compared to baseline

Demonstrates effectiveness in longitudinal and intersection scenarios

Abstract

We consider the problem of human-focused driver support. State-of-the-art personalization concepts allow to estimate parameters for vehicle control systems or driver models. However, there are currently few approaches proposed that use personalized models and evaluate the effectiveness in the form of general risk warning. In this paper, we therefore propose a warning system that estimates a personalized risk factor for the given driver based on the driver's behavior. The system afterwards is able to adapt the warning signal with personalized Risk Maps. In experiments, we show examples for longitudinal following and intersection scenarios in which the novel warning system can effectively reduce false negative errors and false positive errors compared to a baseline approach which does not use personalized driver considerations. This underlines the potential of personalization for reducing warning errors in risk warning and driver support.
