Economic assessment of road safety: usefulness and challenges

Improving road safety requires investment of money, time, and other resources. There are many investment options, and politicians, policy makers, and road authorities need to make choices about how much money they should spend on road safety, which locations to spend it, and the types of road safety measures to use. Economic assessment tools can help decision makers allocate the available resources on those measures that will reduce the number of casualties and level of suffering as much as possible.
