It is generally accepted today that the cervical spine of a car occupant who is involved in a low-speed rear end impact may suffer from soft tissue neck injuries leading to long-term impairment. Therefore, to assess the risk of sustaining such injuries is a major issue in traffic safety, and various neck injury criteria are being discussed for this purpose. In this study a new candidate for suc...

BACKGROUND Clinical and cadaveric studies have implicated that sub-failure cervical instability likely occurs in a subset of whiplash injury patients. Cadaveric studies have suggested that female specimens suffer from more ligamentous stretch injury than males when exposed to simulated rear end crash vectors. However, these findings have never been tested in an in-vivo clinical setting. DESIG...

Forward roadway collision warning systems can reduce rear-end collisions, among other unsafe behaviors. Previous studies have shown that young drivers fail to scan adequately for latent hazards. The current driving simulator study investigates the effect of visual collision warning messages on drivers’ hazard anticipation ability, when presented either 2s, 3s or 4s in advance of a potential thr...

Cooperative vehicle collision warning system is made possible by recent progress in advanced positioning systems and wireless communication technology. In this paper we report our work in developing a cooperative intersection collision warning system that is not limited by the requirement of line-of-sight. The novel elements of the system include the use of a dynamic ad hoc wireless network for...

Rear impact collisions are mostly low severity, but carry a very high societal cost due to reported symptoms of whiplash and related soft tissue injuries. Given the difficulty in physiological measurement of damage in whiplash patients, there is a significant need to assess rear impact severity on the basis of vehicle damage. This paper presents fundamental impact equations on the basis of an e...

Rear-end collisions are caused by drivers misjudging urgent risks while following vehicles ahead in most cases. However, compared with other accident types, rear-end have higher preventability. This study aims to reveal the prone segments and hours of collisions. First, we extracted 1236 cases from traffic records Harbin 2015 2019. These accidents classified as property damage accidents, injury...

Abstract Due to urbanization and the significantly increasing number of vehicles, urban roads are becoming more congested day by day, with result that rear-end collision has become third most common type collision. By developing integrating active passive safety systems, car manufacturers working prevent accidents reduce consequences an accident. The present study examines a braking procedure i...

The characteristics of autonomous vehicles’ collisions from 2021 and the first half 2022 in California confirm trends reported previous years. Driving mode was associated with fewer instances which AV deemed to be at fault a collision. Most were rear-end intersections. Single vehicle occurred mostly manual mode. Collisions vulnerable road users while mode, often right after disengagement In oth...
