Network-wide road crash risk screening is a crucial issue for road safety authorities in governing the impact of road infrastructures over road safety worldwide. Specifically, screening methods, which also enable a proactive approach (i.e. pinpointing critical segments before crashes occur), would be extremely beneficial. Existing literature provided valuable insights on road network screening and crash prediction models. However, no research tried to quantify the risk of crash on the road network by considering its main components together (i.e., probability, vulnerability, and exposure).

全网道路碰撞风险筛查：新框架

全网络道路碰撞风险筛查是道路安全当局管理道路基础设施对全球道路安全影响的关键问题。具体来说，筛选方法也将非常有益，它还可以实现主动方法（即在碰撞发生之前查明关键部分）。现有文献为道路网络筛选和碰撞预测模型提供了宝贵的见解。然而，没有研究试图通过综合考虑道路网络的主要组成部分（即概率、脆弱性和暴露程度）来量化道路网络上的碰撞风险。
