摘要

•A vulnerability modeling framework considers spatial interactions between areas.•Local and neighboring risks are integrated to formulate the vulnerability index.•Particle Swarm Optimization is used to estimate parameter weights for modeling.•Public transport and mobile phone user big data are used in training and validation.•Human movements have strong effects on spatial vulnerability to infectious disease.
