Background: Road crash injury is largely preventable and predictable; it is a human-made problem amenable to rational analysis and countermeasures. All the studies on Road Traffic accidents either use number of accidents or victims according to availability of accident data. Studies combining these two types of data to identify hazardous locations are a rarity. In this study data on both, the n...

BACKGROUND AND RATIONALE Among the adverse events related to tuberculosis treatment, hepatotoxicity is the most serious, and recognition of risk factors for it is essential to achieve successful therapy. The aim of the study is to evaluate the role of anti-HCV as a risk factor for hepatotoxicity in hospitalized patients under tuberculosis treatment with rifampicin, isoniazid and pyrazinamide (R...

OBJECTIVE To quantify the effect of the introduction of 20 mph (32 km an hour) traffic speed zones on road collisions, injuries, and fatalities in London. DESIGN Observational study based on analysis of geographically coded police data on road casualties, 1986-2006. Analyses were made of longitudinal changes in counts of road injuries within each of 119 029 road segments with at least one cas...

This paper presents Direction based Hazard Routing Protocol (DHRP) for disseminating information about fixed road hazards such as road blocks, tree fall, boulders on road, snow pile up, landslide, road maintenance work and other obstacles to the vehicles approaching the hazardous location. The proposed work focuses on dissemination of hazard messages on highways with sparse traffic. The vehicle...

Mix-zones are recognized as an alternative and complementary approach to spatial cloaking based location privacy protection. Unlike spatial cloaking techniques that perturb the location resolution through location k-anonymization, mixzones break the continuity of location exposure by ensuring that users’ movements cannot be traced while they are inside a mix-zone. In this paper we provide an ov...

BACKGROUND Road traffic casualties show some of the widest socioeconomic differentials of any cause of morbidity or mortality, and as yet there is little evidence on what works to reduce them. This study quantified the current and potential future impact of the introduction of 20 mph zones on socioeconomic inequalities in road casualties in London. METHODS An observational study based on anal...

 Abstract: The shipments of hazardous materials (HAZMATs) induce various risks to the road network. Today, one of the major considerations of transportation system managers is HAZMATs shipments, due to the increasing demand of these goods (because it is more used in industry, agriculture, medicine, etc.), and the rising number of incidents that are associated to hazardous materials. This paper ...
