In order to improve road safety, it is necessary to better understand collision processes, i.e. the chains of events that lead to collisions. Among the most important benefits, more efficient countermeasures can be found to target causes and factors known to lead to collisions. This would also help develop more reliable surrogate safety measures based on traffic events without a collision that ...

BACKGROUND Injuries and deaths from road traffic collisions present an enormous challenge to the South African (SA) healthcare system. The use of restraining devices is an important preventive measure. OBJECTIVE To determine the relationship between seatbelt use and injury severity in vehicle occupants involved in road traffic collisions in Cape Town, SA. METHODS A prospective cohort design...

BACKGROUND Kazakhstan, a developing middle-income country, has the highest road traffic collision (RTC) mortality in the European Region. The aims of this study were to determine main characteristics of road traffic fatalities in Semey region, Kazakhstan and to compare findings with National data and middle-income European countries. METHODS This descriptive surveillance study assesses RTC mo...

BACKGROUND The purpose of the study is to determine the epidemiology of road traffic collisions (RTCs) in Trinidad and Tobago by characterizing RTCs in terms of number of collisions, fatalities, victim profiles, and locations for the purpose of informing accident prevention programs. Previous studies of RTCs in Trinidad and Tobago were primarily concerned with patterns of drivers use of seat be...

Half of all reported near mid-air collisions involve at least one general aviation aircraft. More than half of NTSB reports of mid-air collisions occur in the vicinity or in the traffic pattern of an airport, and a majority of them occur at non-towered airports. This paper proposes a concept for traffic collision prevention targeted for general aviation aircraft operating in the vicinity of non...

This study presents a surrogate safety measure for evaluating the rear-end collision risk related to kinematic waves near freeway recurrent bottlenecks using aggregated traffic data from ordinary loop detectors. The attributes of kinematic waves that accompany rear-end collisions and the traffic conditions at detector stations spanning the collision locations were examined to develop the rear-e...

This study aims to identify influencing factors of traffic accidents in Japanese major road through factor analysis and regression analysis for each accident type, considering their characteristics of rare event. The database consists of 5-year accident record and relevant road traffic condition data in major road sections in Aichi Prefecture which includes the third largest conurbation area of...

Objective: One of the most frequent causes of death and acquired disability in the pediatric population is the Traumatic Brain Injury (TBI). TBI is secondary to falls, road traffic and vehicle collisions, child abuse and assaults. Penetrating brain injury is a severe form of traumatic brain injury. Blunt head injury is more frequent than TBI in children, but the second one carries a poor progno...

In this paper we introduce an enhanced DQRUMA/ MC-CDMA protocol for wireless packet networks. The original DQRUMA/MC-CDMA protocol may suffer severe code collisions due to a limited number of request codes. An enhanced DQRUMA/MC-CDMA protocol using minislots for request accesses is proposed to reduce request collisions. In the proposed protocol, request attempts can be transmitted concurrently ...
