| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper describes the relationship between traffic safety and penetration of Autonomous Vehicles (AVs) as well as vehicles equipped with alert-type driver assistance systems with Autonomous Emergency Braking (AEB) systems considering drivers’ reaction delays. Firstly, we introduce an AEB model which activates emergency braking 0.8 seconds after the time of collision warning in our simulator by considering the certification requirements of Advanced Emergency Braking System by the Ministry of Land, Infrastructure, Transport and Tourism. Also, we validate various parameters of AEB compared with previous work which analyze the number of rear-end collisions of vehicles equipped with AEB systems. Secondly, the AEB system which activate emergency braking 0.8 seconds after the time of collision warning is called “common AEB”, in addition the AEB system which activate emergency braking on simultaneously with collision warning is called “immediate AEB”, and accidents reduction properties of each AEB systems toward penetration ratio are compared with safety characteristics of AV. The results show that immediate AEB has almost the same accidents reduction effects to AV, and their accidents reduction ratio approach about 100 % when all the vehicles equippe the AEB systems. Thirdly, we develop penetration scenarios in which common AEB, immediate AEB, and AV are coexist and penetrate, and evaluate accidents reduction effects of them. The four scenarios are developed considering two factors: whether immediate AEB and/or AV is widely used. The results under mixed traffic flow of vehicles equipped with several systems also indicate the similarity in accidents reduction effects between immediate AEB and AV. Therefore, to achieve higher traffic safety, it is effective to penetrate AV as well as shorten the time between collision warning and emergency braking. | |
