California Transportation Disparities Mapping Tool

The Prototype Transportation Disparity Mapping Tool is a project developed to better understand transportation disparities and built environment-related determinants of health in California. This tool focuses on four major categories of disparities:

(i) private vehicle ownership,

(ii) public transit,

(iii) active transportation, and

(vi) transportation networks.

The mapping of these disparities supports agencies and organizations studying climate change and environmental justice.

This tool is a component of larger initiatives of the California Air Resources Board (CARB), which is mandated to assess progress toward climate goals. CARB also aims to ensure all segments of society benefit from California’s climate agenda, including disadvantaged communities, in order to create a more environmentally just future.

The advisory committee that developed this tool includes representation from healthcare, academia, and research, and community organizations. Additionally, a team of researchers and academics, led by Principal Investigator Paul Ong of UCLA Center for Neighborhood Knowledge (CNK), developed and visualized the indicators used in this tool. The development of this guide was funded in part by the California Initiative for Health Equity and Action.

Guidance on how to use this mapping tool as well documentation and methodology can be found in the draft Transportation Disparities Mapping Tool User Guide here.

The full report is forthcoming.
