Get comprehensive data to measure transportation equity

Transportation planning and policy can affect both racial and social equity. We provide objective metrics to measure, evaluate, and support equitable transportation.


The tools you need to measure impact across populations and neighborhoods

Aggregate demographics, including race and income

SANDAG used StreetLight’s demographic metrics to measure the social equity impact of shifting congestion to a toll road. The before-and-after analysis measured whether low-income populations were disproportionately impacted.

Before and After icon

Perform before-and-after studies to measure results

Travel back in time, for specific days and time of day, to see how transportation projects impact the behavior of different groups of travelers.

Use O-D and Zone Analysis for neighborhood-level studies

Study origins and destinations at the street and corridor level to see where groups of travelers come from, and where they go, including O-D for bike and pedestrian modes.


Using LBS Data for Environmental Justice Studies

Make sure that your transportation studies are built on an equitable and representative sample size. Watch our webinar to learn how StreetLight’s location-based services (LBS) data’s sample size and bias compares to traditional surveys for use in environmental justice studies.



Measure equity impact of San Diego's regional toll road

In StreetLight’s first transportation project ever, SANDAG used our Traveler Demographics Metric to measure the social equity impact of shifting congestion to a toll road. The before-and-after analysis, including income and race data, measured whether low-income populations were disproportionately impacted.


Use transportation data to help reduce infant mortality rates

The issue of infant mortality clearly illustrates the interplay of health, socioeconomic conditions, and transportation. This analysis reveals ways that Big Data can help planners address transportation risk factors for infant mortality in areas in Columbus, Ohio.


Project the equity impact of planning decisions

Understand the social equity impact of proposed transportation legislation. This analysis shows how planners can collect key data to better communicate with constituents, and more effectively distribute resources to help mitigate the impact on different populations.


Providing data for academic research in transportation equity

Evacuation risks and social vulnerability

We provided free metrics for a team at the University of Colorado-Boulder exploring the role of social vulnerability on evacuation behavior and risk. 

Any academic researcher whose project aligns with our mission can get free access to StreetLight InSight® Metrics.

Ensuring equity in public spaces

StreetLight gave free metrics to a team at Macalester College studying who has access to and uses public space. This knowledge informs subsequent efforts to understand how public spaces function to include and exclude people, and enhance efforts to build inclusive public spaces in diverse settings.

Unequal impacts of traffic on pregnancy

Exposure to traffic during pregnancy has been linked to adverse health outcomes including preterm birth, a primary predictor of infant mortality.  African American women and other women of color are at increased risk. Researchers at the University of California, UCLA and UCSF campuses are using free traffic metrics provided by StreetLight Data to better understand the risks of traffic-related air pollution to pregnant women and their babies, and the extent to which traffic may contribute to inequalities in adverse birth outcomes.
