Francesco Bella, Manuel Silvestri
The interaction of motorists and bicyclists, particularly during passing maneuvers, is cited as one of the primary causes of bicyclist fatalities. This paper reports the results of a driving simulator study, which sought to analyze the effects that three cross-section configurations of a two-lane rural road and four geometric elements of the road have on driver behavior, during the interaction with a cyclist. A two-lane rural road, about 11km long, was designed and implemented in an advanced-interactive driving simulator...

Nitrous acid (HONO) plays an important role in the formation of OH radicals, which are involved in photochemical oxidation. HONO concentrations in ambient air at urban sites have previously been measured, but very few studies have been performed in central Tokyo. In this study, HONO concentrations in ambient air in southeast central Tokyo (near Tokyo Bay) in winter were determined by incoherent cavity enhanced absorption spectroscopy. The O3, NO, NO2, and SO2 concentrations were simultaneously determined. The NO concentrations were used to classify the parts of the study period into types I (high pollution), II (medium pollution), and III (low pollution)...

Mountainous highways generally associate with complex driving environment because of constrained road geometries, limited cross-section elements, inappropriate roadside features, and adverse weather conditions. As a result, single-vehicle (SV) crashes are overrepresented along mountainous roads, particularly in developing countries, but little attention is known about the roadway geometric, traffic and weather factors contributing to these SV crashes. As such, the main objective of the present study is to investigate SV crashes using detailed data obtained from a rigorous site survey and existing databases...

Background Road traffic injuries (RTIs) are a serious epidemic which claims more than a million lives across the globe each year. The burden of RTIs is particularly pronounced in Africa and other low and middle income countries. The unfavourable disparity of the burden of road trauma in the world is largely attributable to unsafe vehicles, lack of appropriate road infrastructure and the predominance of vulnerable road users (VRUs) in developing countries. However, little research exists in Northern Ghana to highlight the scale and risk of death among road users...

OBJECTIVES: Road traffic injuries (RTI) cause a significant number of injuries and deaths in China every year; the World Health Organization estimated 261,367 deaths due to RTI in 2013. As a result of the ongoing growth of China's economy, road construction and motorisation, RTI are expected to impose a heavy health burden in the future. However, the public and policy makers have not widely perceived RTI as a public health issue commensurate with its consequences, in part, due to a lack of intuitive indicator measuring the health impact...
