Car navigation systems play a prominent role in road traffic safety and traffic regulation. However, it is necessary to improve the route guidance of car navigation systems so that accurately and quickly recognize small differences in location. Thus, to increase the ease of understanding and safety of car-navi systems, navigation systems based on augmented reality have been proposed for providing guidance at road intersections. We are currently developing a car navigation system based on augmented reality, called AR-Navi. We investigated designs for the display of road intersection guidance that can be easily understood even when limited information is available and proposed a “best shot” display method that does not use moving images. In addition, we implemented a prototype system that includes these methods and conducted driving experiments on public roads to evaluate the ease of understanding and safety of AR-Navi. Using the evaluation results, we confirmed that the ease of understanding and safety is similar in the case of AR-Navi and CG-Navi. We also clarified the characteristics of AR-Navi.
