Increasing accessibility and improving cycling safety are the primary objectives of cities and policymakers. In the literature, there are several studies examining cycling safety and few studies examining cycling accessibility. However, few studies conduct a joint examination of these two topics to understand the relationship between them. This paper aims to develop and apply a methodological framework to conduct a joint zone-based analysis of traffic safety and accessibility. The developed framework integrates route choice modelling and four-step modelling into traffic safety and accessibility analysis and the outcome is a novel zone-based crash risk estimation incorporating traffic crashes with trip characteristics (including, trip purpose, origin-destination, and alternative routes). The proposed framework was applied in a case study to examine the injury crash risk imposed on commuting cyclists and job accessibility in the city of Utrecht, the Netherlands.

对交通安全和可达性进行联合区域分析的方法框架


增加可达性和提高自行车安全是城市和政策制定者的首要目标。在文献中，有几项研究探讨骑车安全性，但很少有研究探讨骑车可达性。然而，很少有研究对这两个主题进行联合检验以了解它们之间的关系。本文旨在开发和应用一种方法框架，对交通安全和可达性进行基于联合区域的分析。开发的框架将路线选择建模和四步建模集成到交通安全和可达性分析中，结果是一种新颖的基于区域的碰撞风险估计，将交通碰撞与出行特征（包括出行目的、出发地-目的地和替代路线）结合起来。拟议的框架应用于案例研究，以检查荷兰乌得勒支市通勤骑自行车者的伤害碰撞风险和工作可达性。
