Road Safety

Studies have found that a significant portion of vehicle crashes are caused by human errors. However, a vast body of research has demonstrated that certain modifications to highway infrastructure can decrease the probability that drivers will make errors; that errors will lead to crashes; and that crashes will result in life-altering injuries or death.

The purpose of this study was to estimate the reduction in serious injuries and deaths that could potentially be achieved through investment in highway infrastructure safety measures, and to estimate the level of investment required to achieve those benefits.
