In the post-pandemic era, cities need to be prepared to combat the epidemic for a long time. Epidemic prevention and control become part of the new normal of cities. The executive ability of epidemic prevention and control work will directly affect the normal operation of the city.

As the strategic front line of urban epidemic prevention and control, the rationality of the configuration of urban polymerase chain reaction (PCR) sample collection booth (referred to as PCR booth) and the convenience of PCR testing for residents are the top priorities of urban epidemic prevention and control.

This project is carried on in the context of post-pandemic urban management, focusing on the operation of normalized PCR booth and collecting relevant data such as the spatial location, sampling service mode, sampling service period, and actual sampling results of PCR booths. In Shanghai alone, there were 38,339 PCR booths, including temporary ones, by June 2022. By analyzing the operational status and spatial accessibility of the PCR booths of various types, the project combined the environmental characteristics such as demographic, site conditions, time period, etc. We provided suggestions for optimization of current and future alternative policies.
