With the development of intelligent vehicles and autonomous driving technology,the safety of vulnerable road user(VRU)in traffic has been more guaranteed,and many research achievements have been made in the key area of collision avoidance decision-making *** this paper,the knowledge mapping method is used to mine the available literature in depth,and it is found that the research focus has shifted from the traditional accident cause analysis to emerging deep learning and virtual reality *** paper summarizes research on the three core dimensions of environmental perception,behavior cognition and collision avoidance decision-making in intelligent vehicle *** terms of perception,accurate identification of pedestrians and cyclists in complex environments is a major demand for VRU perception;in terms of behavior cognition,the coupling of VRU intention identification and motion trajectory prediction and other multiple factors needs further research;in terms of decision-making,the intention identification and trajectory prediction of collision objects are not included in the risk assessment model,and there is a lack of exploration specifically for cyclists'collision *** this basis,this paper provides guidance for the improvement of traffic safety of contemporary VRU under the conditions of intelligent and connected transportation.

The 4th International Forum of Automotive Traffic Safety

作者： WANG Zhengguo Institute for Traffic Medicine Dept. 4, Research Institute of Surgery The Third Military Medical University Chongqing, China, 400042

The road vehicle traffic collisions and associated injuries and consequences are recognized as a global public health issue and have attracted increasing attention worldwide. This paper described the characteristics of the road traffic injuries (RTI) between developed and developing countries. The trends of road traffic deaths in different countries was analysed and discussed

＜正＞This study aimed at identifying the occurrence,type and mechanisms of the traumatic injuries of the pedestrians in road vehicle collisions,and investigated the relation between human factor and engineering,environment factors,which forms a basis for improving pedestrian *** traffic accidents in 2001 within urban area of Changsha,the capital of Hunan Province,were investigated in co-operation between Hunan University,Wujing Hospital in China and Chalmers University of Technology in *** 108 cases were collected from Wujing hospital of Changsha,of which 89 cases are vehicle-pedestrian *** analysis was carried out in terms of distributions of the pedestrian age group,gender,injuries and injury severity,as well as the type of ***,the selected 13 cases were analyzed with detailed information about the injury patterns,AIS,GCS and the situation of heal based on hospital *** results were discussed with regard to accident and injury characteristics of *** factors influencing the injury outcomes were proposed and discussed in terms of vehicle transport environment and road *** pedestrian accidents were identified as vital issue in urban traffic safety,and a high priority should be given to this issue to reduce the incidence and the severity of the accidents in an advanced urban transportation system.
