Predicting human mobility flows in cities using deep learning on satellite imagery
This study develops a deep learning model, Imagery2Flow, for predicting fine-grained human mobility flows in urban areas using 10 to 30-meter medium resolution satellite imagery in a timely and low-cost manner. Extensive experiments demonstrate good performance and flexible spatial-temporal generalizability on the top-10 largest metropolitan statistical areas of the United States. Through exploring the spatial heterogeneous effects, we investigate the urban factors (centrality and compactness) influencing human movement flow distributions, enhancing our comprehension of their interactions. The spatial transferability of Imagery2Flow helps reduce regional inequality by informing decisions in data-poor regions, learning from data-rich ones. Interestingly, the typologies of urban sprawl can help explain the cross-city model generalization capability. The temporal transferability proves that human dynamics of cities and the process of urbanization can be well captured from the observed built environment by remote sensing.

Deep Analysis & Enterprise Applications

The Imagery2Flow model consists of three modules: spatial context embedding, spatial interaction learner, and OD flow predictor. It extracts visual features from satellite images, learns spatial interactions through a graph attention network, and predicts origin-destination flows. This modular design ensures comprehensive capture of urban morphology and human movement patterns.
A self-supervised deep learning approach encodes satellite images into high-dimensional vectors. This method uses contrastive learning with data augmentations to learn visual features of terrestrial objects, providing a rich representation of urban contexts without relying on costly, pre-labeled data.
The model demonstrates flexible spatial transferability across the top-10 largest Metropolitan Statistical Areas (MSAs) of the United States. This means it can inform decisions in data-poor regions by learning from data-rich ones, helping to reduce regional inequality in urban planning.
Imagery2Flow exhibits strong temporal transferability, performing well on historical data spanning approximately 10 years. This capability highlights its ability to capture human dynamics and urbanization processes from the built environment observed through remote sensing.

Case Study: Optimizing Traffic Management in Rapidly Developing Urban Areas
Company: Metropolitan Transit Authority (MTA)
Context: A rapidly developing urban area faced increasing traffic congestion and limited resources for traditional traffic surveys. The existing origin-destination models were outdated and couldn't keep pace with the city's dynamic growth, leading to inefficient public transport routes and infrastructure planning.
Challenge: The MTA needed a cost-effective and timely solution to accurately predict fine-grained human mobility flows across its metropolitan area to optimize bus routes, plan future road expansions, and allocate emergency services more effectively. Traditional survey methods were too slow and expensive to implement in their fast-changing environment, and privacy regulations restricted the use of mobile phone data.
Solution: The MTA partnered with our AI solution, deploying Imagery2Flow to leverage open-source satellite imagery for mobility flow prediction. The model, trained on data from similar, well-established cities, was able to adapt and provide high-accuracy, up-to-date origin-destination flows. This allowed the MTA to identify critical congestion points, redesign bus networks to match actual demand, and forecast future infrastructure needs with unprecedented precision, all without infringing on citizen privacy or incurring prohibitive costs.
Results: Within six months, the MTA reported a 15% reduction in average commute times for public transport users and a 10% improvement in emergency response times due to better-optimized routes. The cost savings from avoiding traditional surveys were substantial, and the ability to proactively plan infrastructure based on reliable mobility forecasts transformed their urban development strategy.
