重大公共卫生事件对天津高速公路交通量影响分析

Analysis on the Characteristics of Traffic Volume Changes on Tianjin Expresswayduring Major Public Health Events

为分析新冠病毒疫情对高速公路交通流量带来的影响,基于2021年7月—2022年9月天津市高速公路网交通量调查数据,对新冠病毒疫情常态化防控期间天津市高速公路网交通量特征开展研究。结果显示,新冠病毒疫情常态化防控期间,天津市高速公路网交通量随着疫情形式变化产生较大浮动,客车交通量与新冠病毒阳性感染者人数呈较明显的负相关性;货车交通量在无阳性感染者期间维持在较高水平,随着阳性感染者的增加出现浮动,但相关性不如客运交通量变化显著。

In order to analyze the impact of the COVID-19 on highway traffic flow,based on the survey data of traffic vol-ume of Tianjin's highway network from July 2021 to September 2022,the traffic volume characteristics of Tianjin's highway network during the normalization prevention and control of COVID-19 were studied.The analysis results show that during the normalization prevention and control of the COVID-19,the traffic vol-ume of Tianjin's expressway network fluctuates greatly with the change of the epidemic form.The passenger traffic volume is significantly negatively correlated with the number of COVID-19 positive infections.The truck traffic volume maintains at a high level during the period without positive infections,but fluctuates with the increase of positive infections,but the correlation is not as significant as the passenger traffic volume.
