This study assessed the effects of road-related alteration of substrate, including increased salinity, on vegetation along a meridional gradient in Fennoscandia. Vegetation community composition were surveyed in 29 randomly selected 1-m(2) sized roadside plots. Number of plant species and plant cover (%) on the plots were positively interrelated (p < 0.0001). Both variables also decreased towar...

As vehicular networks become popular, more and more people want to access data from their vehicles. When many vehicles want to access data through a roadside unit, service scheduling becomes an important issue. In this paper, we identify some challenges in vehicle-roadside data access. As vehicles move pretty fast, the requests should be served quickly. Also, vehicles may upload data to the roa...

Many methods have been used to survey red fox (Vulpes vulpes) and gray fox (Urocyon dnereoargenteus) populations. However, none has proven entirely satisfactory, and wild foxes remain one of the most difficult economically important wildlife species to monitor. In this study we evaluated the reliability of a snow track survey method for foxes by investigating whether the average number of road ...

Vehicular ad hoc networks (VANETs) offer a promising technology to promote traffic safety by providing real-time communications in the form of vehicle-to-vehicle and vehicle-toinfrastructure communications. Roadside units (RSUs) play an important role in the dissemination of warning messages that used in VANETs’ safety-related applications. However, due to the expense of deploying and maintaini...

Vehicular Ad Hoc Networks (VANETs) are a peculiar subclass of mobile ad hoc networks that raise a number of technical challenges, notably from the point of view of their mobility models. In this paper, we provide a thorough analysis of the connectivity of such networks by leveraging on wellknown results of percolation theory. By means of simulations, we study the influence of a number of parame...

To facilitate intelligent traffic communication, a reliable, realistic, and network is required for adhoc communication between vehicles. Many requirements compete in the different existing vehicular networking systems. However, one solution to suit all purposes has not been determined. While the vehicle-toinfrastructure, such as standardized GPRS, HSPAm, and LTE, is currently used, vehicle-to-...

Recent studies have identified roadside safety barriers as a cause of severe injuries and fatalities for motorcyclists. Roadside safety barrier have traditionally been designed with limited consideration for motorcyclist safety since the primary focus was on the safety of occupants of enclosed vehicles. Computer simulations of full-scale crashes between motorcyclists and road barriers would pro...

The main objective of this study was to compare the performance of a portable impairment test device known as roadside impairment testing apparatus (RITA) with the field impairment tests (FIT) that are used at the roadside by UK police. One hundred and twenty two healthy volunteers aged 18-70 years took part in this two-period crossover evaluation. The volunteers received a dose of alcohol and ...
