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.
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.WATCH WEBINAR
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.READ CASE STUDY
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.READ BLOG
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.READ BLOG
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.CONTACT US
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.
