Resilience has gained importance in the current research and policy agendas as it incorporates concepts of adaptation and transformation. Urban areas are complex systems exposed to different shocks, which have impacts on its various components. Research in transport has already incorporated the concept of resilience with more or less sophisticated approaches that are intensive on data and technical expertise. There is a need to explore the incorporation of resilience in simpler and less data intensive methods that can be easily applied in a wider range of contexts. One of the aims of this research is to develop a method that can use commonly available mobility management tools allowing smaller urban areas to analyse and plan for resilience. We present a new development of a method to assess resilience in transport systems with a commonly used mobility management tool (the origin-destination matrix) for calculating an overall measurement of resilience. The method assumes that car trips are transferred to active modes or to the available public transport routes in the event of any disruption in the system. We consider different scenarios of availability of public transport in case of disruptive events. We applied the method to two urban areas in Brazil. The variation of the contribution of the public transport presents patterns comparable between the two cases. The spatial distribution of trips shows the relative importance of resilient trips and the cities’ spatial structure. The inclusion of public transport routes has an impact on the levels of accessibility of lower income users.

将公共交通纳入评估城市交通弹性的方法中

抵御力在当前的研究和政策议程中已变得越来越重要,因为它纳入了适应和转型的概念。市区是遭受不同冲击的复杂系统,会对其各个组成部分产生影响。交通运输研究已经将复原力的概念与或多或少复杂的方法结合在一起,这些方法需要大量的数据和技术专长。有必要探索将弹性纳入更简单,数据强度较小的方法中,这些方法可以轻松地在更广泛的上下文中应用。这项研究的目的之一是开发一种可以使用通用的移动性管理工具的方法,从而允许较小的城市区域分析和规划弹性。我们提出了一种使用常用的移动性管理工具(起点-目的地矩阵)来评估运输系统总体弹性的评估运输系统中弹性的方法的新进展。该方法假设在系统发生任何故障的情况下,将汽车旅行转换为主动模式或可用的公共交通路线。在发生破坏性事件的情况下,我们考虑了公共交通可用性的不同场景。我们将该方法应用于巴西的两个城市地区。公共交通贡献的变化呈现出两种情况之间可比的模式。出行的空间分布显示出弹性出行与城市空间结构的相对重要性。纳入公共交通路线会影响低收入用户的可达性水平。
