The recognition that accident externalities are not independent of travel delays, and hence travel time savings and losses will promote a serious policy rethink about strategies designed to reduce the risk of exposure to accidents. The evidence is designed to identify that additional externality that has to be factored into the accident costs to recognise the other sources of externality typically ignored in accident costing and speed restriction studies. The implication on the development of a national program of road safety is likely to be profound.

认识到事故的外部性并不独立于旅行延误，因此节省和损失的旅行时间将促使对旨在减少事故风险的战略进行认真的政策反思。证据的目的是确定额外的外部性，必须考虑到事故成本，以认识到外部性的其他来源，通常忽略了事故成本和速度限制的研究。对制定国家道路安全方案的影响可能是深远的。
