In Japan, the practical use of Cooperative Driving Safety Supp ort Systems (DSSS) and ITS Spot Service as V2I technology was the first of its kind in the world. The global community is not only making efforts to implement this V2 I technology, but also carrying out demonstration tests to realize V2X connectivity technology. On the other hand, big data processing, security measures, and AI technology such as deep learning are becoming the new core of connectivity technology for autonomous driving systems. The world's efforts to realize new values and services will be introduced here. Among them, I will introduce examples of cases where the car probe data of private companies are aggregated and utilized as road traffic information during times of disaster.
In recent years, the technological evolution of automated driving has been remarkable, and the competition toward practical application has intensified. The Japanese government started the SIP automated driving system, and the industry, government and academia are cooperating to undertake research and development together in various areas to overcome the international competition for practical application of automated driving. Automated driving vehicles are based on autonomous sensor control, but using connected technology makes it possible to drive safely and smoothly. I introduce the research and development in “SIP automated driving for universal services” on vehicle to vehicle, vehicle to infrastructure, vehicle to pedestrian and vehicle to network communication (probe car).
Automatic vehicle location system (AVL) is an essential system for providing information on highway buses and should be shared between bus operators and users. This is because, especially in metropolitan areas, delay s caused by traffic jams or accidents significantly influence bus operations and user behavior. In this project, we develop AVL and open data platform using ITS spots on expressways and national highways.
A direct vehicle-to-pedestrian communication system that can alert pedestrians or drivers in appropriate situations and with suitable timing to reduce traffic accidents involving pedestrians is being developed through the contract research and development scheme of the Ministry of Internal Affairs and Communications at the Cross-ministerial Strategic Innovation Promotion Program. Based on past pedestrian accident analysis results, we focused on scenes that should be handled preferentially. Development of a safety support application with a target of a normal operation rate of safety support function of 80% or more and unnecessary support function of unnecessary operation rate of 20% or less is conducted. We developed prototypes of rucksack type terminals. For the large-scale demonstration experiment of 2018, we conducted a preliminary verification in a public road at Odaiba and was able to confirm that the safety support application operation rate for pedestrians and drivers achieves the target rate. We examined safety support technology that can provide appropriate support and confirmed its effectiveness.
Emergency medical care was triggered by an increase in traffic injuries in the 1970s. However, due to social infrastructure development, wearing of seatbelts, a decrease in the total population, the number of accidents and the number of deaths has also decreased. But, with the aging society, an increase in elderly drivers and elderly injured people has become a new problem. In the future, various information will be transmitted from daily activities and an information society will be constructed in which that information will be shared on the cloud. In addition, Advanced Automatic Collision Notification (AACN) and automatic d riving car development will also advance. The relationship between the Emergency Medical Information System (EMIS), which is already being used in disasters, and the high standard vehicle of the Disaster Medical Assistant Team (DMAT) will be a pioneer of an ICT-based connected car society.
Following recent developments in telematics technologies, proactive approaches are being taken even in the field of non-life insurance where these technologies are being utilized to develop services and products. With regard to “telematics car insurance” (the PAYD and PHYD types), which calculates an insurance premium based on the driver ’s driving information, this article will first outline activities occurring in Europe and the U.S. and deliberations, development status and problems with usage diffusion in Japan. Moreover, with regard to situations where insurance companies have been actively working toward utilizing telematic s technologies to provide services to insurance policyholders, this article will make reference to the increasing need for dash cams in recent years and outline this matter by taking the approaches of Mitsui Sumitomo Insurance Co., Ltd. as an example.
This is a report on case studies for the postal service vehicles equipped with connected technology during the social experiment for a safe and secure urban development project run by Kakogawa City, Hyogo, which utilized ICT developed through a public-private partnership. Improvements on safety and security were sought by linking the information logged in the in-vehicle cameras on postal service vehicles during deliveries and BLE beacon detection terminals so that dynamic monitoring is also enabled on residential roads where the installation of fixed surveillance cameras is limited. In addition, locations on residential roads that potentially need repair were estimated and identified using the data obtained from in-vehicle sensors during deliveries, which indicated issues and potential developments toward creating safe and secure communities reveal ed through the social experiment, together with introducing the attempts of road administrators in reducing the man-hours required for field surveys.
Although the number of deaths due to road accidents are decreasing, the rate of decrease is diminishing gradually during recent years, and the rate of accidents among elderly drivers is particularly high. Therefore, in this paper, in order to make clear the driving characteristics of elderly drivers, a survey was conducted on 6,298 drivers in Japan and 430 drivers who have participated in a traffic safety lesson in Kanagawa Prefecture, and analyzed using such methods as a decision tree. As a result, various points were clarified, such as the fact that the number of driving offenses and accidents among elderlies who realize that their senses are deteriorating and the rate of accidents resulting in injury or death caused by elderlies who drive moderately are low, and that elderlies who are embarrassed of causing an accident avoid driving.
The dangers of aggressive driving are attracting increased public attention in Japan. In June 2017, a fatal collision stemming from road rage on the Tomei Expressway in Kanagawa Prefecture sparked a national debate over aggressive d riving. However, aggressive driving is not a new phenomenon. Considerable research on aggressive driving has been done in the United Kingdom and other countries. Therefore, in this research I review the literature on aggressive driving, examine whether the features elucidated by past research apply to cases in Japan, and clarify the features of aggressive driving in Japan. Previous research suggests youth, being male, social class, place and time, and certain triggers are factors influencing displays of aggressive driving. In this case study, data was collected from accidents involving the crime of dangerous driving causing death or injury under the Act on Punishments of Acts Inflicting Death or Injury on Others by Driving a Motor Vehicle, etc. The results indicate that features similar to those in previous research can be seen in Japanese cases in terms of age, sex, social class, and triggers, but not in terms of time.
