Safety performance determines how and why these failures occur on a road network, even in the absence of robust crash data, and gives additional answers to determine what can be done to prevent similar incidents in the future and build more robust economic cases supporting road safety investments.
Selecting a road safety countermeasure can thus be a life-or-death decision: specifiers need to understand certain criteria with regards to available systems or design scenarios, and also have a clear understanding of applicable standards, as well as site-specific conditions where they are to be used. This course reviews the state of knowledge and presents processes to determine appropriate road engineering countermeasures based on these site conditions.
This course introduces scientific principles for forecasting the benefits of road safety projects. The goal is to estimate and defend reductions in fatalities and serious injuries, to assign dollar valuations to proposed improvements, and to compare these benefits to project or program costs.
