Honoring Innovators Who Shaped Transportation Safety
As Black History Month comes to a close — and during a century of national observance — it offers a meaningful opportunity to reflect on the individuals whose innovations still influence transportation safety today. From railroads to highways, many foundational safety advancements were pioneered by remarkable inventors whose work continues to protect drivers, carriers, and the public every day.
Garrett A. Morgan
After witnessing a serious roadway collision, Morgan patented the three-position traffic signal in 1923 — introducing the caution phase that prevents intersection crashes today.
He later sold the design to General Electric and proposed illuminated signals for nighttime visibility, laying the groundwork for modern traffic control systems.
Elijah McCoy
McCoy’s automatic lubrication system allowed train engines to be oiled while in motion, drastically reducing breakdowns and improving operational safety. His reliability earned the famous phrase “the real McCoy.”
Granville T. Woods
Known as the “Black Edison”, Woods developed railway telecommunication systems that allowed trains to communicate with stations and each other — a major advancement in collision prevention and rail traffic coordination.
Andrew Jackson Beard
Beard’s automatic railroad car coupler eliminated the dangerous need for workers to stand between railcars, significantly reducing workplace fatalities in rail yards.
Frederick McKinley Jones
Jones created portable refrigeration units for trucks and railcars, enabling safe long-distance transportation of food and medical supplies. He co-founded U.S. Thermo Control Company and earned a National Medal of Technology — revolutionizing cold-chain logistics still relied upon today.
Meredith Gourdine
Gourdine’s work in exhaust purification and emissions control technology contributed to the development of modern pollution-reduction systems used in vehicles worldwide.
And finally, William T. Coleman, Jr. (pictured); whose name adorns the Department of Transportation Federal Building in Washington, D.C.; recognized as the first African American Secretary of Transportation. Coleman advanced transportation policy, infrastructure oversight and safety initiatives. In the photo he’s pictured cutting the ribbon for the Federal Highway Administration’s Bicentennial Exhibit “Highways of History”.

Why Their Work Still Matters
Every inspection standard, signal light, refrigeration unit, communication system, and roadway safeguard used today builds upon innovations like these. Transportation safety did not emerge overnight — it was engineered, tested, and improved by individuals committed to solving real-world risks. As we conclude Black History Month, we recognize these pioneers not only for their achievements, but for the lasting impact their work continues to have on keeping our roads and rails safe.
At Lee Trans, safety isn’t just compliance — it’s continuing the legacy of innovation that makes transportation safer for everyone.
