New Report Shows Higher Rates of Lung Disease Near Chicago’s Busiest Transit Bus Routes
Data Highlight Urgent Need for Electrification Across City’s Fleet
CHICAGO – Respiratory Health Association (RHA) and University of Chicago Center for Spatial Data Science (CSDS) released findings of a year-long study indicating higher rates of asthma and COPD near several bus routes and garage locations across the city of Chicago. The study, which referenced data from Chicago Transit Authority (CTA) and the U.S. Centers for Disease Control and Prevention, is the first to examine lung disease prevalence in relation to Chicago’s bus routes.
The report analyzed 125 permanent CTA bus routes, classifying seven routes with an average of at least 20,000 riders per day and covering at least seven miles as high-traffic routes. Researchers found residents living within 500 meters (about 1600 feet) of these routes had asthma rates of 11.08%, which is 8.4% greater than the overall city rate. Those living within 500 meters of these routes had a 6.69% COPD rate, 10.6% higher than overall rate across the city. Additionally, residents living closest to any of the CTA’s seven bus garages had asthma rates more than 12% greater than the citywide average and COPD rates 23.6% greater than the citywide average.
“We already know that the air pollution produced by vehicles, including the diesel-powered buses which make up most of the CTA’s current fleet, is dangerous for people’s lungs,” commented Joel Africk, RHA President and Chief Executive Officer. “The higher rates of asthma and COPD along those busy routes – where residents are some of the most vulnerable in the city – show how important it is to replace diesel buses with electric models to improve air quality and protect everyone’s health.”
The report includes recommendations for priority routes to place electric vehicles as well as potential funding sources to support needed infrastructure. It was provided to CTA officials as part of its ongoing strategic planning efforts, which also include plans to reduce pollution produced by city transit vehicles. In 2019, Mayor Lightfoot’s transition team endorsed a goal of fully electrifying the CTA bus fleet and the Chicago City Council passed a resolution supporting complete electrification of CTA by 2040.
“Identifying socially vulnerable areas at greater risk of pollution exposure remains an important area of future research in the work of environmental justice and reducing health disparities,” noted Marynia Kolak, Assistant Director for Health Informatics at the Center for Spatial Data Science. “While these associations are complex, reducing the transit dimension of traffic pollution via electrification is a critical need for the city.”
“Federal, state, and local elected officials need to dedicate the resources needed for the Chicago Transit Authority to accelerate the city’s transition to electric buses,” Africk continued, “so residents – especially those living with lung disease – can enjoy the important health benefits cleaner transportation provides.”
Respiratory Health Association (RHA) has been a local public health leader in Chicago since 1906. RHA works to prevent lung disease, promote clean air and help people live better through education, research and policy change. To learn more, visit www.resphealth.org.
