Purpose
Collecting truck traffic data is vital. It shows the issue through hard numbers. These counts are most powerful when echoing lived experiences.
The data supports the many years of community advocacy and community testimony. We hope that learning more and more about the effects of heavy diesel emissions can lead to changes such as 'zero-emission technologies' that can better our built environment.

Existing truck counts for commercial and industrial vehicles are not easy to attain. Some traffic sources, while thorough, miss collecting data on important neighborhood streets of concern. Other sources show approximations or may not separate trucks from the rest of the flow of traffic. For many, existing traffic studies may need to be requested. Yet these studies may only show traffic at certain peak hours instead of a full day.
This project is a step towards fulfilling the need for accessible, community-level truck traffic in Chicagoland. Our truck counts are designed to be accessible for policymakers, community leaders, and the public. These counts are not estimates, but real numbers.
We hope this new truck count portal contributes to the growing consensus that we must find solutions to toxic truck emissions, especially in communities facing many environmental and social injustices.

Truck & Bus Counts
Traffic cameras were deployed at 47 locations recording over 1,100 video hours of trucks and buses. Below is a snapshot of a 24-hour period of activity across each of those locations.
PM2.5 Emissions
PM2.5 Particulate matter (PM) is a mix of chemicals and solid to liquid compounds. The smaller the PM, the more harmful it is to human health because it can penetrate deeply into the lungs and go into the bloodstream, causing inflammation, asthma, tissue damage, cardiac events, and premature mortality. This PM is less than 2.5 micrometers wide (one micro-meter is one millionth of a meter). This size is much smaller than a strand of human hair which is 50-70 micro-meters wide.
PM10 Emissions
PM10 Particulate matter (PM) is a mix of chemicals and solid to liquid compounds. The smaller the PM, the more harmful it is to human health because it can penetrate deeply into the lungs and go into the bloodstream, causing inflammation, asthma, tissue damage, cardiac events, and premature mortality. This PM is less than 10 micrometers wide (one micro-meter is one millionth of a meter). This size is smaller than a strand of human hair which is 50-70 micro-meters wide. PM10 automatically includes PM2.5.
NOx Emissions
Nitrogen oxides (NOx) are gases made of oxygen and nitrogen that combine with our atmosphere and the sun to create smog pollution, ground-level ozone, and acid rain. Inhaling NOx gases are associated with asthma, heart disease, and all-cause mortality.
How we got here
In 2012 there was a successful campaign to close down the Crawford Coal Power Plant, also called “cloud factory,” in Chicago’s South Lawndale neighborhood. This eventually led Little Village Environmental Justice Organization’s air quality organizing efforts to shift to diesel pollution and truck traffic around 2015. This endeavor was spearheaded by local parents from Zapata Academy, a pre-K - 8th grade Chicago Public School, which sits right next to Unilever, a multi-national company that makes many consumer goods like foods, beverages, cleaning agents, and personal care products. In 2016, Unilever announced plans to expand its Hellman’s mayonnaise factory and distribution center on a vacant site near W 28th St and S Kilbourn Ave. This expansion was set to bring an estimated 500 - 900 additional trucks/day through the neighborhood. Community leaders expressed concerns about this surge in trucks and associated health and safety risks for Little Village residents, especially for young students at Zapata Academy. The community deemed Unilever's proposal to address these concerns with buffers like trees as inadequate.
As concerns over health impacts surfaced, it became evident that addressing systemic issues was necessary, particularly in the face of other companies seeking expansion. This prompted a call for data on commercial and industrial truck traffic in the neighborhood. This call was intensified after the City of Chicago’s Department of Planning and Development, under then-Mayor Emanuel, decided to halt its industrial modernization process to review the Little Village Industrial Corridor. Recognizing the lack of available diesel truck data from city agencies, community leaders partnered with LVEJO to gather truck counts at intersections known for trucking activity. An AP Statistics class from Infinity Math, Science and Tech High School collaborated with LVEJO to conduct truck counts outside their school campus at W 31st St and S Kostner Ave. After analyzing their data, they found that over a 5-hour and 42-minute period, 452 total trucks drove by, averaging 1 truck/minute. This effort by high school youth laid the groundwork for the creation of our Chicago Truck Count Data Portal.
Every student complains about getting to the high school on time because there are trucks up and down 31st Street and just the safety of it. Students also shared their experience with the air pollution and all the smells they get from just walking around the neighborhood. ... To some extent, [the AP Stats students] were just learning math and applying it to a project. But for them to hear that this was actually filling a need in a conversation about mobility justice... I remember they were like ‘Wow, did we just do this important work?’. I said, ‘Yeah, it’s important to look for data where there is data missing so that you can support your claim or fight for justice.’

Moving forward
To eliminate tailpipe pollution, trucks on the road must transition to electric models. Clear The Air Coalition (CTAC) is a group of regional and national environmental justice, public health, climate action, and labor organizations working together to reduce the burden of toxic tailpipe pollution on Illinois communities. Our coalition advocates for policy solutions that will protect our air, our kids, and our future by advancing real climate and environmental justice for all Illinois communities. The Warehouse Pollution Reduction Act, is a solution that will reduce pollution from warehouses by requiring warehouse operators to take actions including clean truck use, EV charging installation, solar energy installation, and local hiring — with faster action in overburdened communities. It will also expand public participation so that impacted communities can participate in permit review processes for new and modified warehouses and will create a publicly accessible registry that includes warehouse locations, associated truck traffic, pollution reduction progress, and labor conditions amongst much more.
The ACT ensures that more medium- and heavy-duty zero-emission trucks show up on the roads running next to and through environmental justice communities and that means less damage done to the lungs of people by harmful diesel exhaust. With big vehicles running on electricity that is increasingly generated by zero-emission renewable wind and solar power, harmful pollution isn’t simply shifted to another community but is truly eliminated.

Apart from trucks, all freight movements– trains, ships, and aircraft– need to become electric and source their electricity from clean and renewable energy.
Yet a transition to electrification alone is not enough.
A Just Transition is a non-negotiable framework to integrate into an electric truck future. In a Just Transition, equitable processes would ensure no one gets left behind in the shift to a clean fuel economy. This means prioritizing workforce training and good working conditions for truck drivers, mechanics, and all other workers affected by this shift. Environmental justice advocates also call for a systemic shift in ending worker and resource exploitation worldwide which would otherwise still exist in a clean fuel economy without a Just Transition. Critically, more funding for public transit and city re-designs favoring people over vehicles helps address the root issue.
An intentional downscaling or degrowth of the global economy paired with local community development of disinvested areas is another piece of the solution beyond vehicle electrification.
We hope that this project inspires further truck count locations and permanent truck traffic data collection in Chicagoland.
Better truck traffic data can better verify existing traffic estimates and studies, inform permitting processes and other policies, add to the understanding of cumulative impacts especially in environmental justice communities, and advise a Just Transition to truck electrification.
