A detailed study has been conducted to determine the contamination of Thohoyandou roadside soils, vegetation, sewage and river waters by Zn, Cu, Cr, Pb, Cd, Fe, Pt and Pd. The study further investigated the correlation between these trace metals in roadside soils and vegetation in order to infer the potential impacts of roadside trace metals contamination of vegetation. Collected surface soil a...

City road verges often represent existing green space and provide opportunities for ecological enhancement. Urban greenspace improvement initiatives at the residential verge scale require genuine community support engagement success. We examined a community-based voluntary assisted greening program designed to enhance connectivity using native plants in local municipality Perth, Western Austral...

This study examined the spatial, socioeconomic status (SES), and temporal patterns of ambient air pollution in Accra, Ghana. Over 22 months, integrated and continuous rooftop particulate matter (PM) monitors were placed at a total of 11 residential or roadside monitoring sites in four neighborhoods of varying SES and biomass fuel use. PM concentrations were highest in late December and January,...

VANETs has emerged as the new network environment for intelligent transportations systems. In this paper, we focus on two types of VANET applications and evaluate the effectiveness of our data dissemination protocol for these two types of applications. In particular, we investigate traffic monitoring (TM) and roadside message transfer (RMT) applications. The traffic monitoring application (TMA)...

Prototype guardrails, bridge rails, crash cushions and other roadside safety hardware have been designed in part by using engineering judgment, experience and intuition. These prototypes have been later evaluated by performing full-scale crash tests representing expected worst case scenarios. Since these tests are relatively expensive and because they require specialized facilities and personne...

The Road Transport Legislation Amendment (Drug Testing) Act 2006 commenced in December 2006 and authorised roadside drug testing in NSW, and the drug testing of any driver, motorcycle rider or supervising licence holder involved in a fatal crash. A review of the drug testing legislation was undertaken in 2008 to determine whether or not the new laws were meeting their policy objectives of detec...

Driving under the influence of substances (DUI) other than alcohol has been the subject of increasing interest over the past few decades (Schulze et al., 2012). As with alcohol, research has shown that drug intake increases the risk of road traffic accidents (Elvik, 2013; Schulze et al., 2012; Verstraete & Legrand, 2014). Intervention in this area is a priority. A key factor for deterring DUI i...

In vehicular-to-roadside (V2R) communications of vehicular network, the bandwidth from roadside unit (RSU) can be shared among vehicular users to improve the utilization and reduce the cost. In this paper, the coalition game is formulated to model the situation in which multiple vehicular users can cooperate to share the bandwidth to RSU. First, the rational coalition formation is considered in...
