Vehicular Ad Hoc Networks (VANETs) are attracting the attention of researchers, industry, and governments for their potential of significantly increasing the safety level on the road. In order to understand whether VANETs can actually realize this goal, in this paper we analyze the dynamics of multihop emergency message dissemination in VANETs. Under a probabilistic wireless channel model that ...

OBJECTIVES To investigate post-crash time management by police. METHODS The retrospective study comprised data related to all road traffic crashes from March 2009 to March 2010 in Sistan and Baluchistan province of Iran. Data was retrieved from the standard national form designed for road traffic crashes completed by police officers present at the scene. SPSS 15 was used for statistical analy...

In this paper, a control scheme for emergency braking maneuvers in automated highway systems (AHSs) and a new online identification scheme to determine the tire–road friction characteristics of the vehicle are presented. The proposed controller determines the required pressure in the master cylinder of the braking system to achieve maximum deceleration during braking, based on the estimation of...

Vehicles are part of people’s life in modern society, into which more and more high-tech devices are integrated, and a common platform for inter-vehicle communication is necessary to realize an intelligent transportation system supporting safe driving, dynamic route scheduling, emergency message dissemination, and traffic condition monitoring. TrafficView, which is a part of the e-Road project,...

Road Traffic Crash (RTC) is the eighth leading cause of death globally. In a recent World Health Organization report, there were 5,192 RTC deaths reported from Pakistan in 2010. The Road Traffic Injury Research and Prevention Center (RTIRPC) is a unique public-private public health enterprise in Karachi, and collects data from five major public and private hospitals' emergency departments in th...

Traffic safety is a very important issue in modern society and the last couple of years researchers have started looking at telecommunication solutions to enhance traffic safety. More specifically researchers are looking at emergency alert services, enabling cars to warn eachother for incidents (slippery road, accident, . . . ). Existing forwarding protocols for vehicular networks often use an ...

conclusions planning for the prevention of traffic accidents requires standardized data. as the foundation for crash prevention efforts, existing standard data infrastructures present policymakers and government officials with a great opportunity to strengthen and integrate existing accident information systems to better track road traffic injuries and fatalities. results an (mds) of a traffic ...

BACKGROUND Use of opioids may predispose drivers to road trauma, yet the effect of opioid dose on this association is unknown. METHODS We conducted a population-based nested case-control study of patients aged 18 to 64 years who received at least 1 publicly funded prescription for an opioid from April 1, 2003, through March 31, 2011. Cases were defined as having an emergency department visit ...

Following the 2004 Indian Ocean tsunami all roads in the affected areas in Sri Lanka were inaccessible during the immediate aftermath of the disaster either due to the damages they sustained or poor networking of roads and lack of contingency planning within the road network systems. This paper aims at proving the necessity of effective mainstreaming of disaster risk reduction during road recon...

INTRODUCTION Injuries represent a significant cause of morbidity and mortality worldwide and road traffic crashes accounts for a significant proportion of these injuries. Tanzania is among the countries with high rates of road traffic crashes. The aim of this study was to determine the pattern, associated factors and management of road traffic injury patients in Tanzania. METHODS A cross-sect...
