The Role of Landmark Information in Intelligent Navigation Displays

Abstract

Advanced Traveler Information Systems (ATIS) are advanced communication and navigation systems that use computer-based in-vehicle systems to provide navigation and travel-related information to drivers. To help drivers navigate effectively and get to their destinations quickly and safely, navigational information must be effectively communicated to the driver. Landmarks are important environmental and navigational cues that help drivers to get to their destinations. This paper describes a study that tested the influence of landmark information in route guidance displays on navigation performance in a simulated driving environment. Forty-eight participants drove in a high-fidelity simulator and navigated using route guidance displays with and without landmark icons. The results indicated that landmarks were beneficial as a navigation aid; they helped drivers make turning decisions more quickly, especially in reduced visibility conditions (i.e., foggy conditions). Landmarks were particularly beneficial to older drivers by improving their turning accuracy and turn signal accuracy, especially in the fog.
