Visualization of vehicle lateral position in winter road environment using GNSS data

Abstract

In winter road environments of snowy and cold regions, drivers face severe conditions such as icy sur faces, low visibility, and roads narrowed by snow accumulation. Current strategies to aid road users mainly provide information about road conditions, snow coverage, and visibility. However, this paper introduces a novel approach focused on driver behavior, particularly changes in the lateral position of vehicles, rather than road-focused information. High-stress and dangerous driving environments often force drivers to alter their driving behavior. By visualizing locations on a map where lateral position changes frequently, we aim to assist drivers in selecting safer routes. This paper proposes a method to visualize these changes in driving position using GNSS data and demonstrates the effectiveness of this method through experiments.
