A Framework for Using AI-Enabled Infrastructure Monitoring as a Public Health Intervention

Published in: Data-Smart City Solutions Program, Bloomberg Center for Cities, at Harvard University

This new framework proposes a method for cities to transform infrastructure monitoring into actionable public health strategy, prioritizing repairs where they're needed most while reducing health disparities.

A growing number of cities are adopting sophisticated tools capable of detecting, classifying, and mapping infrastructure conditions at a scale and resolution that was previously unattainable. AI-enabled monitoring systems now generate continuous, geospatially precise inventories of sidewalk, roadway conditions, and other above ground attributes, capturing deterioration patterns that evolve long before visible failure or injury occurs. Yet the availability of this data alone does not guarantee improved public health outcomes. Without an explicit framework for interpretation, prioritization, and action, AI-generated insights risk remaining isolated within engineering or asset management workflows and disconnected from the health systems they could meaningfully inform.

This article proposes a practical framework for translating AI-enabled infrastructure monitoring into preventive public health action. It reframes infrastructure condition data as a form of environmental health surveillance that can guide equitable resource allocation, risk reduction, and accountability for injury prevention, instead of just a passive diagnostic input.

Building Comprehensive Infrastructure Baselines

The foundation of any health-oriented infrastructure strategy is a comprehensive and standardized baseline of existing conditions. Cities can create detailed inventories with AI-monitoring systems that move beyond coarse asset ratings to capture specific distress types, severity levels, spatial extent, and precise location. Unlike traditional inspections, which are episodic and can be subjective, automated assessments provide uniform coverage across neighborhoods and generate data that can be updated regularly.

Establishing such baselines is critical for two reasons. First, it allows cities to quantify the true scope and distribution of infrastructure risk, including hazards that may not yet have generated complaints or injuries. Second, it creates a reference point against which future deterioration or improvement can be measured. Without a baseline, prioritization decisions remain reactive and anecdotal, driven by visible failures or political pressure rather than systematic risk assessment.

Integrating Infrastructure Data with Public Health and Exposure Metrics

Infrastructure condition data acquires public health relevance only when it is linked to information about exposure, vulnerability, and outcomes. A cracked sidewalk does not pose the same risk in all contexts. Risk is shaped by who uses the space, how frequently it is used, and the susceptibility of those users to injury; for example, an elderly person walking to take the bus.
