The roadside-to-vehicle communication system is an infrastructure network to be deployed along the roads, which is an important part of the vehicular Ad Hoc networks for future intelligent transportation systems. Vehicle position estimation is a key technology for roadside-to-vehicle communication. In this study, a roadside-to-vehicle communication system is proposed where a camera is fixed on ...

The inhalable particles from vehicle exhaust can cause DNA damage to exposed organisms. Research on DNA damage is primarily focused on the influence of specific pollutants on certain species or the effect of environmental pollution on human beings. To date, little research has quantitatively studied the relationship between roadside pollution and DNA damage. Based on an investigation of the roa...

Moose (Alces americanus ) vehicle collisions (MVCs) are an issue throughout the distribution of moose. Many mitigation strategies have been tested and implemented to reduce the number of MVCs, but there have been few empirical analyses of the effectiveness of roadside vegetation cutting. The goal of this study was to determine if roadside vegetation cutting attracted moose into roadside areas t...

BACKGROUND Many argue that prohibition creates more troubles than alternative policies, but fewer than half of American voters support a taxed and regulated market for cannabis. Some oppose a regulated market because of concerns about driving after smoking cannabis. Although a roadside sobriety test for impairment exists, few voters know about it. The widespread use of a roadside sobriety test ...

Communication between vehicles is a very promising technology to reduce fatalities and injuries in road traffic. Vehicles spontaneously form communication networks where they exchange messages to warn surrounding vehicles. Theoretically, this system is open to any communication node that is equipped with the required communication technology. This openness demands appropriate security mechanism...

Vehicle interactions with roadside restraints such as crash barriers and bridge parapets are extremely complex events and the outcome can be greatly influenced by very local effects. Such impacts typically take place over a time period of 2-3 seconds which presents particular challenges when simulating the process numerically. The inclusion of these local effects necessitates very small time in...

This paper reports on a study that formed part of a Europe-wide investigation of the impact drugs, medications and medical conditions have on road safety (the IMMORTAL project) (Impaired Motorists, Methods of Roadside Testing and Assessment for Licensing). This larger research programme is investigating the accident risk associated with different forms of driver impairment and the implication f...

ABSTRACT – Inter-vehicle and vehicle to roadside communication (V2X communication) allow both passenger safety and driving comfort to be improved significantly. For example, a vehicle detecting an icy road could inform following vehicles and thereby prevent accidents. Vehicle to roadside communication could be used near construction sites to warn the vehicle driver about reduced number of lanes...

Background: Haematotoxicity occurs following acute and chronic low dose exposures to lead. This study aimed to assess the association between occupational lead exposure and haematological parameters among roadside and organized panel beaters in Enugu Metropolis, Nigeria, 2018-19.  Materials and Methods: This was a cross-sectional and analytical study of 428 roadside and organized panel beaters...
