From Hand Signals to Smart Crosswalks: The Evolution of the Modern Pedestrian Signal
Discover the history of the modern pedestrian signal, from Garrett A. Morgan’s groundbreaking traffic signal to today’s smart, accessible crosswalks.
Every day, millions of people rely on pedestrian signals to cross busy street safely. A glowing white walking figure, an orange-red hand, and a countdown timer have become familiar sights around the world. While these signals may seem like simple pieces of infrastructure, they are the result of more than a century of innovation, engineering, and public safety improvements.
The modern pedestrian signal did not appear overnight. Instead, it evolved through the contributions of inventors, engineers, city planners, and transportation officials who continually refined traffic control systems as cities grew and automobiles became more common.
The Early Days of Traffic Control
Before electric traffic signals, intersections were controlled by police officers, railway-style semaphores, or even hand signals. As horse-drawn wagons gave way to automobiles in the early 1900s, traffic congestion and accidents increased dramatically, creating an urgent need for better traffic management.
One of the earliest electric traffic lights was installed in Cleveland, Ohio, in 1914. It used red and green lights and was manually operated. While it improved vehicle movement, pedestrians still had to judge for themselves when it was safe to cross.
Garrett A. Morgan’s Breakthrough
One of the most important milestones came in 1923 when inventor and entrepreneur Garrett Augustus Morgan received U.S. Patent No. 1,475,024 for an improved traffic signal.
Morgan’s design introduced a third position in addition to “Stop” and “Go.” This intermediate phase temporarily stopped traffic in every direction before allowing vehicles to proceed. The brief pause reduced confusion at intersections and provided additional time for pedestrians to cross safely.
Morgan reportedly developed his design after witnessing a serious traffic accident. His invention demonstrated how thoughtful engineering could improve public safety while making increasingly busy streets more efficient.
Although Morgan did not invent the illuminated “WALK” and “DON’T WALK” pedestrian signal used today, his three-position signal became a foundational step in the evolution of modern traffic control.
The Birth of Dedicated Pedestrian Signals
As cities expanded after World War II, pedestrian safety became an even greater concern. More people were walking in increasingly crowded downtown districts, and separating pedestrian movements from vehicle traffic became a priority.
During the early 1950s, several American cities began experimenting with dedicated pedestrian signals. New York City became one of the first major municipalities to install illuminated “WALK” and “DON’T WALK” signs at busy intersections.
These early systems gave pedestrians their own designated crossing phase, reducing conflicts with turning vehicles and improving safety at some of the nation’s busiest intersections.
Standardization Across America
By the 1960s and 1970s, traffic engineers recognized the importance of creating consistent traffic control devices nationwide.
The Manual on Uniform Traffic Control Devices (MUTCD) established national standards for traffic signs, pavement markings, and pedestrian signals. Standardized designs helped ensure that pedestrians could understand crossing signals regardless of where they traveled in the United States.
Eventually, words gave way to internationally recognized symbols—a walking person to indicate it was safe to cross and an upraised hand to indicate pedestrians should wait. These symbols transcended language barriers and improved accessibility for visitors and non-English speakers.
The Countdown Era
One of the most significant modern improvements arrived with pedestrian countdown timers.
Rather than simply flashing a warning, countdown displays show exactly how many seconds remain before the crossing phase ends. Research has shown that countdown timers help pedestrians make better crossing decisions and improve compliance with traffic signals.
Today, countdown timers have become standard equipment at intersections across much of the United States.
Accessibility Takes Center Stage
Modern pedestrian signals are designed to serve everyone.
Accessible Pedestrian Signals (APS) now provide audible tones, spoken messages, vibrating push buttons, and locator sounds that assist pedestrians who are blind or have low vision. These features allow more people to navigate intersections independently and safely.
The continued development of accessible technology reflects a broader commitment to making transportation systems inclusive for all users.
The Future of Pedestrian Safety
Pedestrian signals continue to evolve.
Many cities now use smart traffic systems that detect pedestrians waiting to cross, automatically adjust signal timing based on traffic conditions, and prioritize people walking during busy periods.
Researchers are exploring artificial intelligence, connected vehicle technology, and sensor-based systems capable of communicating directly with autonomous vehicles. Future pedestrian crossings may adapt in real time to weather conditions, crowd sizes, emergency vehicles, and even the needs of older adults or individuals with disabilities.
A Legacy Built by Many Innovators
The pedestrian signal we know today is the product of more than a century of collaboration and innovation.
Early traffic engineers created the first electric traffic lights. Garrett A. Morgan improved intersection safety with his groundbreaking three-position traffic signal. Transportation agencies standardized traffic control devices, while engineers continued refining pedestrian technology through countdown timers, accessible features, and intelligent traffic systems.
Every safe crossing today reflects the work of countless inventors, planners, researchers, and public officials dedicated to protecting lives.
As cities continue to grow and transportation technology advances, the humble pedestrian signal remains one of the most effective—and often overlooked—public safety innovations ever developed.

What is Nude Recreation Week?
Nude Recreation Week is a real event that promotes the idea of enjoying the outdoors without clothing.
Nude Recreation Week is a real event that promotes the idea of enjoying the outdoors without clothing. It is a week-long celebration of the human body and its natural state. The history of Nude Recreation Week is a fascinating one, with its origins dating back to the early 1970s.
The idea of Nude Recreation Week came from a group of naturists who wanted to promote the benefits of nudity in the outdoors. They believed that nudity was a natural and healthy way to enjoy the outdoors, and that it allowed people to connect with nature in a more meaningful way. The first Nude Recreation Week was held in 1976, and it has been celebrated every year since then.
There are many ways to celebrate Nude Recreation Week legally. Many naturist organizations offer events and activities that are open to the public, such as nude hikes, beach cleanups, and other outdoor activities. There are also many private resorts and campsites that cater to naturists, and they offer a variety of activities and amenities for those who want to enjoy the outdoors in the nude.

Lowe’s Is Calling on Creators to Help Design—and Launch—New Products
Lowe’s announced Creator: Into the Blue, a new program letting creators pitch product ideas and work with Lowe’s teams to develop and potentially launch items in retail. Applications are open through Sept. 1, 2026.
Lowe’s is taking its creator strategy beyond sponsored posts and curated storefronts. On June 23, 2026, the home improvement retailer announced Lowe’s Creator: Into the Blue, a new program that invites creators to pitch product ideas and, if selected, work with Lowe’s teams to develop and potentially bring those products to retail shelves.
The announcement arrives as the Lowe’s Creator Network hits its one-year milestone—an initiative Lowe’s launched in 2025 and billed as the first creator network in the home improvement industry. Now, Lowe’s says it’s expanding the pathway for creators: from making content about products to creating products themselves.
From content to creation: what “Creator: Into the Blue” is
Lowe’s Creator: Into the Blue is designed as a forum for creators—both current members of the Lowe’s Creator Network and newcomers—to submit innovative product concepts for consideration. Selected creators could receive support from Lowe’s internal teams across product development, product design, sourcing, and merchandising, with the goal of turning audience-inspired ideas into real-world items that can scale.
In other words: creators aren’t just being asked to promote what already exists. They’re being invited to help shape what comes next.
How this fits into Lowe’s bigger strategy
Lowe’s positioned the new program as a natural next step that builds on two existing pillars:
- Lowe’s Creator Network (launched 2025): A program connecting creators with Lowe’s to share DIY projects, home improvement inspiration, and product recommendations. It also includes personalized Lowes.com storefronts so creators can curate product selections for their audiences.
- Lowe’s Into the Blue (launched 2022): A separate initiative focused on helping entrepreneurs bring innovative products to Lowe’s customers.
Now, Lowe’s is essentially merging the momentum of both worlds—creator-led influence and entrepreneur-led product innovation—into a single on-ramp for creators who want to build businesses through product development.
MrBeast is the proof-of-concept
Lowe’s also pointed to its recent collaboration with global creator MrBeast as an example of how creator partnerships can evolve beyond content and curation. The collaboration included a collectible toy kitdeveloped with Lowe’s—showing how a creator’s audience and brand can translate into physical products that connect with customers in new ways.
That collaboration is now being used as a signal: if a creator with a massive following can co-create a product with Lowe’s, the company wants to open similar opportunities to creators of all sizes.
What creators can submit
According to Lowe’s, creators can submit a range of ideas, including:
- Existing products seeking distribution, scale, and retail exposure
- Product ideas that need development and sourcing support
- Collaborations tied to an existing Lowe’s product line
The message is clear: you don’t have to show up with a fully manufactured item. You can show up with a concept—especially one shaped by what your audience keeps asking for.
Application window and where to apply
Applications are open now through Sept. 1, 2026 at Lowes.com/CreateWithLowes. Lowe’s will review submissions after the application period and announce selected creators at a later date.
Creators interested in applying should also review the full terms and conditions on the application page.
Why this matters for the creator economy—and retail
Creator-led product lines aren’t new, but Lowe’s move is notable because it’s coming from a major home improvement retailer with deep sourcing and distribution infrastructure. If executed well, Creator: Into the Blue could become a meaningful bridge between:
- Audience-driven product demand (what communities want)
- Retail-grade execution (design, sourcing, merchandising)
- Shelf-level distribution (scale and visibility)
For creators, it’s another sign that the creator economy is maturing: the next phase isn’t only about views and engagement—it’s about IP, product development, and scalable revenue.
The bottom line
With Lowe’s Creator: Into the Blue, the company is betting that creators can do more than inspire projects—they can help design the tools, kits, and products people use to complete them. And for creators looking to turn their audience into a business, Lowe’s is offering a new route: pitch an idea, build it with support, and potentially launch it at retail scale.
