The Design of a Graphics-Based Traffic Information System Based on User Requirements

Abstract

This paper reports the results of several studies designed to investigate commuter behavior and decision making with the goal of obtaining functional requirements for a user-based advanced driver information system (ADIS). To achieve this objective, the following tasks were performed: (1) a large sample survey was administered to 9, 652 motorists commuting to a downtown location, (2) an in-depth interview was conducted focusing on the individual motorist's commute, and (3) a questionnaire was administered to investigate the relationship between various forms of graphical traffic information on commuter behavior and decision making. The information obtained from the above studies is being used to design traffic information screens that form the focal part of an ADIS.
