Spatial accessibility and equity analysis of Amazon parcel lockers facilities

The onset of the COVID-19 pandemic has accelerated the growth of e-commerce and home deliveries. Automated parcel lockers are a way to improve delivery efficiency, but despite their rapid growth, little is known about their accessibility and equity impacts. Among e-commerce players in the U.S., Amazon stands out by its large market share. This research studies the location of Amazon lockers in Portland, Oregon utilizing highway, land use, employment, and sociodemographic datasets. Geographical tools and cluster analysis are utilized to estimate accessibility and equity metrics. Lockers tend to be located in mixed-use areas and can be utilized by a large percentage of the population. However, the equity metrics indicate that the current distribution of lockers could be improved to reach traditionally underserved populations. Given the environmental and economic advantages of lockers, policymakers should encourage the expansion of this type of last mile solution to avoid market failures in areas that are currently underserved.
