TMF Collaborates with the Okinawa Prefectural Police Headquarters to Develop Accident Prevention Approaches Integrating Police Accident Data with Vehicle Data

Okinawa, Japan, Mar 19, 2024 - (JCN Newswire) - Since concluding a collaboration agreement with the Okinawa Prefectural Police Headquarters in February last year, Toyota Mobility Foundation (TMF) has been working to analyze police accident data, vehicle data (passenger cars and commercial vehicles), and rental car in-vehicle app data. This work is being carried out together with TOYOTA Rent a Car Okinawa, Yazaki Corporation, JTB Corporation, Toyota Motor Corporation, the University of the Ryukyus, and The School of Engineering at The University of Tokyo in an arrangement involving industry, government, and academia.

Currently, the data sets are being pooled to pursue various measures, such as identifying dangerous locations, investigating the causes of accidents, formulating countermeasures, and verifying their effectiveness as efforts to develop accident prevention measures progress. Additionally, efforts to reduce rental car accidents, promote tourism, and alleviate traffic congestion through in-vehicle apps continue to produce positive outcomes.

The main achievements are listed below.

Moving forward, TMF will advance this initiative under the name “Okinawa Yuimaru Project,” which means working together (= "yui") and mutual assistance (= "mawaru, maru") in the Okinawan language, and further efforts will be made to solve regional issues such as reducing traffic accidents and promoting tourism.

1. Progress with Infrastructure measures

Through multi-faceted analysis combining police accident data with vehicle data (from Yazaki Corporation and Toyota Motor Corporation), progress is being made to identify dangerous locations and reflect this information in road safety measures in collaboration with various administrative agencies.

Road safety measures utilizing data related to braking suddenly, an action highly correlated with traffic accidents, are being implemented in collaboration with Ginowan City, Nishihara Town, and the Naha Port AuthorityAs a means to improve school route safety, work is being carried out in collaboration with Nago City to address speeding that accompanies the use of backroads as shortcutsAccident data and vehicle data are combined to estimate risk factors for dedicated left-turn lanes, a common roadway format in Okinawa with a high accident rate

2. Changes in driving behavior thanks to dedicated in-vehicle tablets

Vehicles equipped with dedicated tablets (manufactured by Yazaki Corporation) demonstrated reduced accidents during the demonstration period, logging a 55% decrease in accidents for non-Japanese and 38% for Japanese nationals. Additionally, analysis of vehicle data showed an improvement in the number of instances of sudden acceleration and sudden braking, supporting the decrease in the number of accidents.

The number of vehicles equipped with a dedicated tablet has been increased from the initial 20 to 50. Additionally, vehicles utilizing in-vehicle multimedia, newly developed by Toyota Motor Corporation to diagnose driving behavior and provide warnings, have been added as we continue expanding our monitoring of changes in driver behavior.

3. Promoting changes in tourist behavior by providing information on attractive new destinations via an in-vehicle app

Recommending nearby attractions (when renting and when the vehicle is stopped) along routes different from those suggested by in-vehicle car navigation systems to tourists in rental cars planning to visit the Churaumi Aquarium led to visits to those attractions, thus contributing to the promotion of hidden tourist attractions and the alleviation of traffic congestion.

Tokio Marine & Nichido Fire Insurance Co., Ltd. has newly joined the collaborative arrangement, which has been extended to March 2025. This deepens the industry-government-academia collaborative analysis by adding data from a non-life insurance company. Going forward, we will further focus on establishing the “Okinawa Model” that combines solutions to social issues, such as reducing traffic accidents and alleviating traffic congestion, with the added value of providing an enjoyable tourism experience.

To achieve traffic safety, it is important to have “Integrated Three Part Initiatives" of People, as in educational activities for drivers and pedestrians; Vehicles, as in the development of safe vehicles; and Traffic Environment improvements, such as the installation of traffic signals and road maintenance.

In addition to a full range of educational tools and activities coordinated with relevant organizations, all aimed at “people,” TMF is promoting efforts to realize a "society with zero fatalities and injuries from traffic accidents" by combining existing technologies and adopting new technologies and perspectives.
