Recently, the cooperative system(CS) has been developed in the world, which is called as a new generation ITS technology. The feature of CS technology is to communicate between vehicle and vehicle(V2V), and between vehicle and infrastructure(V2I) in the field, not via the ITS center in the existing ITS using VDS(vehicle detection systems) and VMS(variable message signs). So, the CS technology can prevent vehicle related incidents or reduce their impacts on drivers/passengers and infrastructures by detecting critical factors to cause vehicle's accidents and providing drivers with those warning messages.
This study has implemented an effect analysis of CS on traffic safety. This analysis has used the accident data of 5 years data between 2007 and 2011 in the Road Traffic Authority(KoROAD). The traffic accidents have been categorized by 50 types approximately, to match with the CS technologies(i.e., V2V and V2I) and AV(Autonomous Vehicle). The analysis result has showed that the V2V and V2I technologies can prevent or reduce the traffic accidents by 76%, if all vehicles and road infrastructures(i.e., road-side equipments) are installed/deployed with CS. This result implies that the CS may be key ITS technologies for traffci safety innovation traffic safety in the future.
In addition, this study has also proposed the international cooperations in the field of CS based ITS, since the CS is considered as competitive technologies in the international as well as national ITS markets. In reviews of the international cooperations between EU, and US, and Japan, this study has finally suggested that our government needs to conduct the research & development(R&D) project for commercializing the CS technologies, and international cooperations by working groups such as safety, mobility, and standardization
