Intersection of the road is one of the accident-prone locations for the traffic. Nearly sixty percent of all traffic accidents each year occur around the vicinity of intersections in Japan. To avoid accidents in the vicinity of intersections, it is considered to be important that drivers are able to confirm the flashing green and non-flashing red of pedestrian signals, and the remaining wait time displayed by pedestrian signals. Therefore,this study is based on a assumption that the confirmation of a pedestriansignal enables the drivers to anticipate the change of the signal to yellow, and this provides allowance time for the proceed or stop decision; andthereby this leads to improved safety at intersections. In this paper, safety level of the signalized intersection with pedestrian signal is evaluated by the user experiment data collected in the laboratory. As a result, it was clearly shown that anticipation of a signal change to yellow by using a pedestrian signal enables a vehicle to avoid the dilemma zone; and the safety at the intersection when the signal changes to yellow is thereby better than the case where such information is not provided.
