The objective of this study is to determine the traffic safety situation of child occupants in the urban areas of Changsha, China. For this purpose, accident data were collected from the local traffic police authority. The selected samples have been dated from January 1, 2001 to December 31, 2010, durich which 1,629 traffic accidents involving chil...
Head impact usually causes fatalities of riders in motorcycle accidents. The use of helmet can protect head effectively and the study of head injury mechanism is useful in safety helmet design and head injury risk decrease. A real motorcycle-passenger car accident was reconstructed in order to simulate and analyze the motion, impact velocity, impac...
The vehicle traffic accidents have been widely studied not only in the motorized countries but also in the motorizing countries, while in-depth study on motor-scooter accidents has not been adequately investigated. In this research the motor-scooter accident data from IVAC in Changsha of China were collected from in depth accident investigation, at...
The impact scenarios, impact velocity were investigated based on 224 car-electric bicycle collision cases in IVAC (In-depth Investigation of Car Accident in Changsha) database. Cars were classified into three types: sedan, SUV and one box. According to analysis of traffic accident data, car-electric bicycle collision models were built up by using M...
This paper aims to determine the correlation of the throw distance of cyclist and electric bicycle in traffic accidents with throw vehicle impact speed. A total of 22 vehicle-electric bicycle accidents were sampled from IVAC database, China. The selected accidents were reconstructed by using PC-Crash and Madymo programs. The relationship between th...

... The head-only simulation is not able to replicate the second impact stage with the ground [17][18][19][20]22]. This is partially evidenced by the fact that existing research work has largely focused on the first impact alone [23][24][25]. Secondly, for the head-only simulation, the calculated kinematics-based head injury responses (HIC 15 , linear and angular acceleration of the head center of gravity COG) are notably lower than those obtained using the full-scale human body model, which suggests that ignoring other body segments may be inadequate [20,26]. In comparison to the growing body of helmet-related studies that focused on the head injuries of cyclists, the influence of wearing a helmet on the cyclist's neck was largely ignored. ...
... In real life, physiological impulses are notoriously slow and have a poor signal-to-noise ratio (SNR).This necessitates the use of an amplifier with a high common mode rejection ratio; such high-quality bioappliers are normally built into the analogue front end of massive stationary systems. Because of the various leads and electrodes required, such instruments are well suited for clinical settings where patients are typically stationary (except for cardiac stress tests), resulting in a low noise level [1] A motorcycle helmet is a form of protective headgear worn by motorcyclists. Motorcycle helmets help to keep riders healthy by shielding their heads in the event of an accident. ...

... Finally, in the event of a real-world accident, a VRU usually has an avoidance motion, such as holding the head with hands, jumping up or curling up [74]. These actions are difficult to reproduce in simulation, which may lead to a certain impact on the validity of the results [75,76]. ...
... They are also the majority of rearseat occupants in the United States of America (USA) [2]. Vehicle accidents are the leading cause of injury and death to children in both Europe and the USA [1,3], Singapore [4], China [5], UAE [6], and several other high-income countries around the world [7]. Children account for about 30% of all road traffic injuries and fatalities worldwide with over 1000 deaths daily due to road traffic collisions [8]. ...
