Analysis of Pedestrian-Fatality Statistics in Japan and the US and Vehicle-Pedestrian Communication for Vehicle-Pedestrian Crash-Warnings

Vehicle-pedestrian crashes are more likely to result in fatalities or severe injuries as compared to vehicle-vehicle crashes. Therefore, various vehicle-pedestrian crash-warning solutions have been proposed. In this report, we first analyze pedestrian-fatality-statistics in the world, Japan, and the US; we then examine various vehicle-pedestrian crash-warning solutions, including three types of communication-solutions that can detect pedestrians in non-line-of-sight: “pedestrians’ communication-modules communicate to vehicles directly”, “vehicles’ modules detect pedestrians’ mobile-phones”, and “vehicles and pedestrians communicate through mobile-network”. Next, we analyze technical challenges in communication-solutions: channel-congestion, communication-delay, and others. Finally, we conclude this report with approaches to implement communication-solutions for vehicle-pedestrian crash-warnings © 2018. Society of Automotive Engineers of Japan, Inc.
