The Impossible Trinity of Human Space Usage between Home, Workplace and Amenity

We propose an impossible trinity of human space usage between home, workplace, and amenity in this paper to explain mobility pattern changes and shifts in demand for space during COVID-19. We developed detailed time usage and location visit profiles for 60,131 people in England and Wales by analyzing about 120 million cell phone location and timestamp records from March 2020 and 2021. We found that both at-home time and amenity visits increased during COVID-19, while workplace visits decreased. Individual visits to different locations are determined by three key factors: individual preference measured by pre-pandemic location visit frequency, time constraints influenced by work-from-home, and space accessibility. We also find that WFH improves equality of individual amenity usage between people of different incomes. Low-income and middle-income people saw an 8% and 4% increase in additional amenity visits, respectively, compared to high-income people during the pandemic.
