| 摘要： | Over the past 30 years, significant progress has been made in reducing the number of highway fatalities that occur in run-off-the-road (ROR) accidents. A critical element in the projection of benefits is the severity of those crashes that are expected to occur with and without a particular treatment. These benefits are currently estimated in a multistep process that relies in part on severity indices. This synthesis traces the historical development of severity indices and notes elements of consistency and disparity in the results of different studies. |
