This paper documents some tests of 802.11b wireless communication technology for vehicle to roadside communication. Data has been collected for a single vehicle communicating with a dedicated roadside antenna. The work is part of a larger effort to benchmark possible throughput of off-the-shelf wireless technologies. The results show that high-speed communication is possible over distances of u...

ƒ A significant minority of REU reported engaging in specific harm reduction strategies as a result of the introduction of roadside drug testing. BACKGROUND Driving under the influence of illicit drugs and/or alcohol is a significant road safety concern (1-3). Although changes in actual crash risk vary between drugs, all illicit drugs are associated with cognitive and performance effects that a...

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...
