Abstract

The focus is on the design of advanced traveler information systems (ATIS) from the user's perspective. Based on the experimental results of this research, types of ATIS information that meet drivers' needs and capabilities and offer effective method(s) of conveying the information are identified. A driving simulator was developed to assist the investigation. The research results indicate that a driver's familiarity with a given traffic network significantly affects his or her perception of the ideal type of ATIS information and the most effective information conveyance method. When traveling in a familiar network and encountering congestion and delay caused by an unexpected traffic incident, drivers need only short and simple information, such as the location of the incident and expected delay time, to assist them in making route diversion decisions. It was found that drivers prefer to receive an auditory ATIS message when traveling in a familiar traffic network. For navigation assistance in an unfamiliar environment, travelers strongly indicated the need for information such as alternative route recommendations and directions to alternative routes. The combined format of auditory message and visual display was perceived as the best way to transmit information in a network with which a driver is unfamiliar. Analysis of driving simulator results also confirmed that a visual display causes greater distraction from driving than an auditory message.
