The impact of the COVID-19 pandemic has been observed to affect the travel patterns, routes and traffic in public transportation systems across the world. It is important to evaluate the performance of the Delhi Metro (DM) post-COVID-19 pandemic for its successful operation In this study, the BLUE line of DM with the longest route and highest number of metro stations has been examined for performance evaluation. The performance is evaluated based on travel time components (access, egress, transfer, waiting and main haul time) to calculate various performance indicators i.e., Level of Service (LOS), Service Time Ratio (STR), Passengers Waiting Index (PWI), Total Travel Ratio (TTR) and Interconnectivity Ratio (IR). The post-COVID-19 LOS evaluation indicates that the users are spending 72.6 % to 84.4 % of their main haul time on their access-egress trips. The STR shows that the users are spending 10.9 % to 12.6 % of their total travel time in waiting and transferring only during the main haul trip. The mean PWI, RI and TTR are noted as 1.008, 0.794 and 2.069 respectively. The IR is observed as 0.312 for the given route. The median and average main haul distances across all access modes are observed to be (12-21) Km. and (19.69 ± 11.19) Km. respectively. It is revealed that the observed mean value of LOS is (0.775 ± 0.575). It is further revealed that the metro fare per trip and the access-egress trip cost per day are significant factors for access mode choice in the case of walking and auto-rickshaw whereas LOS, RI and PWI are other significant operator's performance indicators influencing the access mode choice. The study reveals that post-COVID-19 the performance indicators exhibit the unsatisfactory performance of DM and there is further scope to improve the UMTS performance.
据观察，新冠疫情的影响改变了世界各地公共交通系统的出行模式、路线和交通状况。为确保德里地铁（DM）的成功运营，评估其在新冠疫情后的运行情况至关重要。在本研究中，为进行性能评估，对DM线路最长、地铁站数量最多的蓝线进行了考察。基于出行时间组成部分（进站、出站、换乘、等待和主要行程时间）来评估性能，以计算各种性能指标，即服务水平（LOS）、服务时间比（STR）、乘客等待指数（PWI）、总出行比（TTR）和互联互通比（IR）。新冠疫情后的LOS评估表明，用户在进站 - 出站行程上花费的时间占主要行程时间的72.6%至84.4%。STR显示，用户仅在主要行程中，在等待和换乘上花费的时间占总出行时间的10.9%至12.6%。平均PWI、RI和TTR分别为1.008、0.794和2.069。给定路线的IR为0.312。所有进站模式的中位数和平均主要行程距离分别为（12 - 21）公里和（19.69 ± 11.19）公里。结果显示，观察到的LOS平均值为（0.775 ± 0.575）。进一步研究发现，单次地铁票价和每天的进站 - 出站行程成本是步行和乘坐自动人力车时进站模式选择的重要因素，而LOS、RI和PWI是影响进站模式选择的其他重要运营绩效指标。研究表明，新冠疫情后，性能指标显示DM的运行情况不尽人意，仍有进一步提升UMTS性能的空间。
