摘要:

测量交通性能对于管理交通的公共机构和计划旅行的个人至关重要,特别是在发生特殊事件时。COVID-19大流行对日常生活的几乎每个方面都产生了重大影响,包括城市交通模式。因此,衡量COVID-19对交通的影响,以进一步指导机构和居民妥善应对交通模式的变化至关重要。然而,大多数现有的交通性能指标只包括一个单一的交通参数和措施,只有个别走廊的性能。为了克服这些挑战,在这项研究中,提出了一个流量性能评分(TPS),采用多个参数来测量网络范围内的流量性能。华盛顿大学STAR实验室开发了一个交互式的基于Web的TPS平台,提供实时和历史的时空交通性能分析。基于该平台的数据,本研究分析了COVID-19对不同路段和整体交通网络的影响。考虑到这场疫情极大地重塑了社会和经济运作,本研究还从出行需求和驾驶行为两个角度评估了COVID-19如何改变城市交通。

英文摘要:

Measuring traffic performance is critical for public agencies who manage traffic and individuals who plan trips, especially when special events happen. The COVID-19 pandemic has significantly influenced almost every aspect of daily life, including urban traffic patterns. Thus, it is important to measure the impact of COVID-19 on transportation to further guide agencies and residents to properly respond to changes in traffic patterns. However, most existing traffic performance metrics incorporate only a single traffic parameter and measure only the performance of individual corridors. To overcome these challenges, in this study, a Traffic Performance Score (TPS) is proposed that incorporates multiple parameters for measuring network-wide traffic performance. An interactive web-based TPS platform that provides real-time and historical spatial-temporal traffic performance analysis is developed by the STAR Lab at the University of Washington. Based on data from this platform, this study analyzes the impact of COVID-19 on different road segments and the traffic network as a whole. Considering this pandemic has greatly reshaped social and economic operations, this study also evaluates how COVID-19 is changing the urban mobility from both travel demand and driving behavior perspectives.
