论文摘要

2022年,乌克兰遭受了入侵,随着时间的流逝和地理位置的急剧影响。本文研究了使用分析以及基于区域的网络模型对持续中断对交通行为的影响。该方法是一种数据驱动的方法,该方法利用了在进化算法框架内获得的旅行时间条件,该算法框架在基于流量分配的自动化过程中渗透了来源的需求值。由于实施的自动化,可以近似多个城市的每日模型。本文与先前发表的核心方法的新颖性包括一项分析,以确保获得的数据合适,因为由于持续的破坏,某些数据源被禁用。此外,新颖性包括将分析与中断时间表的直接联系,以新的方式检查相互作用。最后,确定了特定的网络指标,这些指标特别适合概念化冲突中断对交通网络条件的影响。最终目的是建立过程,概念和分析,以促进快速量化冲突情景的交通影响的更广泛的活动。

In 2022, Ukraine is suffering an invasion which has resulted in acute impacts playing out over time and geography. This paper examines the impact of the ongoing disruption on traffic behavior using analytics as well as zonal-based network models. The methodology is a data-driven approach that utilizes obtained travel-time conditions within an evolutionary algorithm framework which infers origin-destination demand values in an automated process based on traffic assignment. Because of the automation of the implementation, numerous daily models can be approximated for multiple cities. The novelty of this paper versus the previously published core methodology includes an analysis to ensure the obtained data is appropriate since some data sources were disabled due to the ongoing disruption. Further, novelty includes a direct linkage of the analysis to the timeline of disruptions to examine the interaction in a new way. Finally, specific network metrics are identified which are particularly suited for conceptualizing the impact of conflict disruptions on traffic network conditions. The ultimate aim is to establish processes, concepts and analysis to advance the broader activity of rapidly quantifying the traffic impacts of conflict scenarios.
