Significant research has been undertaken on how changes in speed limit-for example, the introduction of 30 kilometers per hour, or kph (20 miles per hour, or mph) speed limits-impact safety both when combined with, and without "traffic-calming" engineering treatments such as speed humps or...

In many countries around the world, deficiencies in data or data quality impair evidence-based road safety policy making. While many countries collect road safety data, the collection is not necessarily comprehensive. Further, many countries can be unaware of data gaps in their system, which...

Low- and middle- income countries typically lack adequate systems for collecting road crash data. This limits their capacity to monitor, effectively advocate for, manage, and efficiently improve road safety. While many cities, states, and countries have adopted or developed proprietary systems...

Road crashes are among the most significant public health issues of the century; they account for 97 percent of deaths across all modes of transport. The latest WHO estimate of 1.34 million road crash deaths and up to 50 million injuries per year reflects a slight increase in deaths over...

Safety is one of four global goals identified in the Global Mobility Report (GMR)—along with universal access, efficiency, and green mobility. The safety goal is aimed at curbing the human pain, suffering, loss, grief, and economic costs of transport-crash-related injuries and deaths. The...

The paper attempts to analyze the impact of trade liberalization policy, in terms of FDI, on the level of informal competitive wage rate as well as on the size of the informal sectors of a developing economy with dualistic economic structure in a general equilibrium framework. The wage rate...

Statistical modeling of traffic crashes has been of interest to researchers for decades. Over the most recent decade many crash models have accounted for extra-variation in crash counts?variation over and above that accounted for by the Poisson density. The extra-variation ? or dispersion ? is...
