Injury Mechanisms in Roadside Motorcycle Collisions
More motorcyclists are fatally injured each year in guardrail crashes than passengers of any other vehicle, while only accounting for three percent of the vehicle fleet. Since motorcyclists account for a high percentage of these fatalities, the goal of zero deaths on the road cannot be achieved …

Assessment of road pollutants in roadside retention ponds.
Road networks are a significant, yet understudied, contributor to microplastic (MP) pollution in the environment. Road runoff contains particulate matter (e.g., tyre and road wear particles (TRWPs) and paint fragments) and dissolved chemicals (e.g., leached tyre and plastic related additive …

Investigating sustainable solutions for roadside gully pot management
Roadside gully pots are an important component of urban drainage, with over 17 million examples in service throughout England and Wales. Their main purpose is to retain sediments from road runoff, leaves and organic litter in order to avoid blockage or hydraulic restriction of the drainage system. …

Ecosystematic studies on roadside vegetation in southwestern Virginia
Thirty-two roadside sites throughout seven counties in Southwestern Virginia were investigated with respect to life form, dispersal type and floristics. A floristic checklist of 247 species, 182 genera and 57 families was compiled. Dispersal mechanism and life form were determined for each species. …
