In-Vehicle RGI System For Improving Mobility Of Foreign Tourists

This paper reports on a research project undertaken to investigate four types of RGI (Route Guidance Information) systems and to evaluate the suitability of the systems, which are designed to improve safety and mobility for foreign drivers who drive temporarily in Japan. Twelve foreign drivers (non-Japanese speaking or reading) were asked to operate a driving simulator while using four types of route guidance information developed by utilizing arrow-type and map-type information. Glance behavior including fixation time, glance frequency, and mental workload were measured. The authors found that the most suitable navigation system for foreign drivers provides selectable information by driver’s control, which is supported by more explicit and simple information than that of the current navigation system. In-vehicle navigation systems in Japan traditionally provide route guidance information based on conventional maps; in the United States, route guidance information is usually based on step-by-step direction arrows and remaining distance, which is called the turn-by-turn concept. The best results were found in the RGI systems where the driver could choose which approach he preferred.
