纽约市实时指挥中心

这是如何计算的： The resident count projects forward from the 2020 U.S. Census baseline of 8,336,817 at 0.4% annual compound growth , consistent with NYC Department of City Planning post-pandemic recovery estimates , to produce today's figure. The seven activity bars divide that population using a time-of-day behavioral model with nine distinct hourly windows: midnight-5 AM, 5-7 AM, 7-9 AM, 9 AM-noon, noon-2 PM, 2-5 PM, 5-7 PM, 7-10 PM, and 10 PM-midnight. Each window draws on three calibration sources: MTA小时闸机数据 drives the Commuting share, which peaks at 26.5% during the 7-9 AM subway rush and 27.7% during the 5-7 PM outbound surge; 纽约地铁工作人员的美国时间使用调查微观数据 anchors Sleeping (76% at midnight, under 1% at 5-7 PM), Working, and Eating distributions; and NYC DOT 行人计数与 BLS 消费者支出数据相结合 inform Walking and Shopping. Shopping is held below 2.5% from midnight through 7 AM , when the overwhelming majority of NYC retail is closed and only 24-hour bodegas and pharmacies operate , rising to a peak of 13.2% in the 2-5 PM afternoon retail window. Every time window assigns a distinct percentage to each activity: no two behaviors share the same value within any block.
