Study on Traffic Accident Injuries for Manual Wheelchair Users based on Pedestrian Traffic Accident Statistics

Ryo Oga (National Research Institute of Police Science)

Research on traffic accidents involving manual wheelchair users is limited. In Japan’s traffic accident statistics, accidents involving manual wheelchairs are tallied as a category of pedestrians. Therefore, this report examines information on accidents involving manual wheelchairs using traffic accident statistics. It reports on the characteristics of traffic accident injuries to wheelchair users based on information such as the main parts of the body damaged.

A Scoping Review on Electric Scooter Collisions, Falls and Injuries

Akihiro Kido･Ryo Oga (National Research Institute of Police Science)

While electric scooters are gaining popularity, research on their collision and falling phenomena remains limited. This study presents a scoping review that included international research papers to organize studies related to electric scooter collision and falling phenomena. Additionally, it compiles knowledge about injuries resulting from these accidents.

A Study of the Mutual Safety for Vehicles and Bicycles on Road Traffic using Accident Statistics Data Analysis
-A Study of Cyclist Injuries in Collisions with Passenger Vehicles and Large Size Trucks-

Yasufumi Sekine (Fukuyama University)

As a principle rule, bicycles should ride on the roadway when there are both sidewalks and a roadway. However, if a bicycle and a vehicle collide, there is a high possibility that the cyclist will be killed or seriously injured. In this paper, accident statistics data on vehicle and bicycle collisions were analyzed and their characteristics were clarified. Based on the characteristics of these bicycle accidents, the author would like to discuss the desirable coexistence of automobiles and bicycles in road traffic.

Among bicycle-vehicle accidents, collisions at intersections without traffic lights are the most common. To prevent this accident, we have developed a bicycle approaching notification system that uses smartphones. In this study, with the cooperation of taxi and delivery drivers, we conducted an evaluation of the effectiveness and acceptability of this system notification on public roads. We also considered the accident reduction effect of deceleration using system notifications.

Study on Advanced Emergency Braking System for Electric Scooter

Electric scooters are not subject to the Advanced Emergency Braking System(AEBS) control. However, brcause their silhouettes are similar to those of pedestrians, it is conceivable that the AEBS could be activated. The presence or absence of AEBS activation is important in traffic accident analysis. In this study, We clarified the behavior of the AEBS for electric scooters.
