Background In the state of Victoria in Australia, the development of effective alcohol and driving legislation has produced significant reductions in alcohol related road trauma over the past three decades. The development of drug driving legislation in recent years has followed a similar progression from providing for impairment based enforcement to the recent introduction of random roadside s...

Traditional wireless Medium Access Control (MAC) protocols suffer from a number of drawbacks when used in vehicle to roadside networks. This paper proposes an efficient MAC protocol that addresses a number of critical aspects required for MAC protocols for vehicle to roadside networks including elimination of hidden terminals, prioritized and fast handoff, fairness among nodes and optimal choic...

The data presented in this article are related to the paper "Prevalence of psychoactive substances, alcohol and illicit drugs, in Spanish drivers: A roadside study in 2015". (https://doi.org/10.1016/j.forsciint.2017.07.005) Domingo-(Salvany et al., 2017) [1]. In that paper it was not possible to directly compare 2015 results with previous editions for various reasons, one of which was the lack ...

Soil heavy metals along roadsides pose a great threat to ecosystems while their spatial variations and influencing factors still remain unclear in some regions, especially tropical areas with complex landscape characteristics. Our study was carried out determine how the land use, vegetation characteristics, topographical distance road affect soil metal distribution. Taking Jinghong county Yunna...

Road reserves have a rich history of human impacts, and are important social, economic and ecological component of agricultural landscapes in Australia. Road verge, or roadside environments are gaining greater recognition for their role in nature conservation. In Australia, road reserves are areas of public land retained for the development of future roads. Many road reserves were originally su...

Continuous and simultaneous observational particulate matter (measured as PM10), nitrogen dioxide (NO2) and oxides of nitrogen (NOx) data were captured at a kerbside site alongside a major highway in Auckland, New Zealand, and at a pair of setback sites within 250 m of the highway, day and night over 8 weeks. The three measurement sites were intended to allow emissions from the highway to be la...

Roadside vegetation provides numerous environmental and psychological benefits to drivers. Previous studies have shown that natural landscapes can effectively lower crash rates and cause less stress and frustration to the driver. However, runoff the road crashes resulting in a collision with a tree are twice as likely to result in a fatality, thus reinforcing the need to examine the placement o...
