Inariyama tunnel of Hanshin expressway Kyoto route (Route 8) is directly connected to the local road. The approach length to the intersection to the local road from the expressway tunnel mouth is only 140m so that the expressway vehicles could not reduce the speed because of the short approach length to the intersection. The sequence design method that is commonly used for the environmental effect in the architectural field is applied for the traffic safety measure in order to reduce the speed of the expressway vehicles. Quantitative analysis was conducted to measure the speed reduction effect by questionnaire method using CG movies and effective sequence design was developed. Moreover, the effect is also confirmed by the driving experiment using the real tunnel, the wall of which was painted in the developed sequence design. The new proposed traffic measure is very effective and no accident was reported so far.
