“…In [ 14 ], this scenario is called “End-over, endo, reverse wheelie” and is described as follows: “An extreme forward pitching motion; typically resulting in the rider and the rear frame assembly going over the front wheel in the direction of travel.” In only 6 out of 921 cases with a loss of control of the PTW rider, the authors found such an accident scenario. Brown et al [ 15 ] analyzed causal factors for PTW accidents in which as one of the most common accident causes, they revealed a scenario called “looked but failed to see.” This might also apply to our case. A literature research did not reveal any other reports comparable to our case.…”

The reconstruction of traffic accidents involving powered two-wheelers (PTWs) frequently proves to be a challenging task. A case in which a fatal head-on crash of a PTW with a small truck where only minor vehicles damage was observed but resulted in isolated fatal chest trauma is discussed here. External examination of the corpse revealed two lacerations on the back, at the first glance implying sharp trauma. Based on the accident traces, the technical expert assumed an emergency break of the PTW rider resulting in a rotation of the PTW in terms of a wheelie on the front wheel. The first contact between the PTW rider and the tail end of the small truck probably occurred with the upper side of the helmet, and then, the back handle of the PTW caused the stab-like injuries followed by compression of the rider between the small truck or asphalt and the PTW. Based on the few accident traces available, neither a reconstruction of the pre-impact velocity nor a detailed reconstruction of the PTW rider kinematics was possible. However, using an interdisciplinary approach, the principal collision position as well as the injury mechanisms could be reconstructed.

“…The references [2,34,35,36,37,38] reported death and injury statistics. Concerning collision avoidance systems, the studies in [39, 40,41,42,43,44] investigated the role of the VRU as an active actor in road accident prevention through V2VRU communication. The work in [13] provides more articles, reports, and news covering VRU-related issues since 1994.…”

5G-enabled V2X communications for vulnerable road users safety applications: a review

2022

Intelligent Transportation System (ITS) is continuously evolving alongside communication technologies and autonomous driving, giving way to new applications and services. Considering the significant rise in traffic casualties, protecting vulnerable road users (VRU), such as pedestrians, cyclists, motorcycles, animals, etc., has become ever more critical. That said, technological advances alone can not meet the requirements of such crucial applications. Therefore, combining them with architectural revolutions, particularly cloud, fog, and edge computing, is essential. In this review, we scrutinize the VRU safety application with regard to technological evolution. This review establishes the foundations for designing resilient, more reliable, end-to-end VRU protection services. It illustrates the possibility of combining the performance of different technologies through exploiting 5G architectural advantages (function placement, direct/indirect communication, etc.) for the intended application. In the context of 5G architecture, collision avoidance systems consider network and application-related challenges and solutions. This survey provides standardization, studies, and project efforts related to the use case and considers the different types of messages in the V2VRU communication-based safety application. We investigate how adapting the application parameters to the network state and devices' available resources can use network resources efficiently and provide reliable services.

“…It is well known that motorcyclists involved in accidents have a high risk of severe trauma due to the lack of protection of the motorbikes [ 1 ]. Although lesions are reported to affect the entire body, mostly the head and thoracic areas [ 2 , 3 , 4 ], head trauma still represents one of the major causes of death among riders [ 3 , 5 ].…”

“…Despite these laws, there are still many risk factors and incorrect behaviors that can lead to very serious accidents which turn out to be fatal in spite of the helmet. Major risk factors may be behavioral, like speeding, risky driving, alcohol and drugs abuse, geophysical, such as road geography, weather and surface conditions, and situational, for example traffic and objects on the site of impact and many others more [ 1 , 12 , 13 , 14 , 15 ]. All these factors can contribute to making the helmet’s protection ineffective in case of accidents [ 14 ], not only by causing polytraumas, but also overmatching impact resistance of the helmet itself when the head represents the primary impact site.…”

When the Helmet Is Not Enough: Forensic Multidisciplinary Reconstruction of a Deadly Motorcycle Accident

et al. 2022

We report the case of a 54-year-old man who died in a motorcycle accident due to loss of control of the vehicle on a viaduct. No other vehicles were apparently involved, except for a car hit by the motorcycle after it fell. A post-mortem CT scan (computed tomography scan) was performed showing complex head trauma with a subarachnoid hemorrhage and multiple skull and facial bone fractures. A forensic cinematic reconstruction performed by an engineer was needed to exclude other incident causes other than the loss of control. The multidisciplinary approach that included autopsy findings, a cinematic reconstruction, a helmet test and an examination played a key role in clarifying the dynamics of the accident, allowing us to explain how the death occurred despite the motorcyclist’s helmet use. The cause of death was identified as a penetrating head trauma with cerebral material exposure, produced by the impact of the head against a fixed bolt in the guardrail base. Despite the use of the helmet, the impact force was enough to render the protection ineffective and allowed the bolt to penetrate through the helmet and the skull.
