BACKGROUND Feral populations of cultivated crops can pose challenges to novel trait confinement within agricultural landscapes. Simulation models can be helpful in investigating the underlying dynamics of feral populations and determining suitable management options. METHODOLOGY/PRINCIPAL FINDINGS We developed a stage-structured matrix population model for roadside feral alfalfa populations o...

Roadside vegetation barriers are used in many urban areas to restrict air and noise pollution from reaching roadside pedestrians, but their effectiveness in limiting the movement of nanoparticles is not yet known. This study investigates the influence of a roadside vegetation barrier on particle number distribution (PND) and concentration (PNC) and associated exposure under different wind direc...

BACKGROUND An estimated one in five drivers will be over 65 by 2030. Compared with their younger counterparts, older adults are more likely to experience health and functional impairments, including cognitive dysfunction, which may interfere with their ability to drive safely. Law enforcement officers, as part of the public safety community, need help in developing the necessary skills to ident...

The dispersion of motorcycle related injuries and deaths might be a result of disparity in motorcycle helmet use. This study uses national roadside survey data, injury sentinel surveillance data and other national data sets in 2010 of Thailand, a country with high mortality related to motorcycle injuries, to explore the disparity in helmet use, explanatory factors of the disparity. It also asse...

We present a routing guidance approach that can be used in Intelligent Vehicle Highway Systems (IVHS). We consider IVHS consisting of automated highway systems on which intelligent vehicles organized in platoons drive to their destination, controlled by a hierarchical control framework. In this framework there are roadside controllers that provide speed and lane allocation instructions to the p...

Background In an effort to change drinking and driving behaviour and reduce the number of serious crashes attributable to alcohol, in the spring of 2010 the Government of British Columbia, Canada announced new measures to deal with drinking drivers. Aim This paper presents evidence of the impact of new immediate roadside prohibitions (IRP) for drinking drivers as assessed by random roadside sur...
