How Seattle’s Transit System Works

Now that you know how to get to PacSci, let’s take a look at the engineering that keeps Seattle’s public transit running smoothly. 

Eric from INIT, who works with King County Metro and the ORCA card system, explained how their technology helps track buses and keeps them on time. “We use technology to monitor where buses are, predict delays, and keep things running efficiently,” Eric said. This helps make sure your bus gets you to PacSci on time, even during Seattle’s busiest hours. 

The ORCA system also has a special testing lab where new technology is checked before it’s used in public. Eric shared that, “Every time you tap your ORCA card, a lot is happening in the background to make sure your ride is smooth.” 

Plus, King County Metro operates a 24/7 control center where workers monitor routes, solve problems, and keep transit moving. This teamwork ensures that buses and trains are reliable no matter what challenges they face, like traffic or weather. 

A Light Rail Ride Away

For those who prefer the light rail, Jordan, a Link light rail operator, shared insights into how the system is evolving to meet the needs of Seattle’s growing population. “The light rail is powered by clean, carbon-free electricity,” Jordan explained. “This makes it a great option for getting around the city while reducing our carbon footprint.” 

Exciting developments are on the horizon, as Jordan mentioned that the light rail is expanding to cover more neighborhoods, improving access for families and individuals alike. New stops will connect underserved areas, making it easier for everyone to reach cultural institutions like Pacific Science Center. 

As families plan their visits to PacSci, riding the light rail offers an eco-friendly, convenient way to travel. Jordan encouraged readers to take advantage of the service, “Using the light rail helps ease traffic on the roads and reduces pollution, all while giving you a scenic view of Seattle as you travel.” 

Whether you’re visiting for a day of exploration or commuting daily, Jordan and the light rail team are committed to providing a safe and efficient transportation option that supports a vibrant, connected Seattle. 

Careers in Public Transit

Public transit offers a variety of exciting STEM careers that help shape our communities. 

• Transportation engineers design and improve transit systems, ensuring they are safe, efficient, and accessible while using math and physics to solve complex challenges.  

• Data analysts collect and analyze data to help agencies optimize routes, schedules, and service frequency, ensuring better service for riders.  

• Environmental scientists assess the impact of public transit on the environment and develop strategies to minimize its carbon footprint, focusing on sustainability. 

• Information technology specialists manage systems for ticketing, scheduling, and real-time tracking, playing a crucial role in ensuring smooth operations.  

• Urban planners design and develop urban spaces, including transit infrastructure, taking into account factors like population growth and community needs.  

• Skilled workers like mechanics and technicians maintain buses and trains, ensuring vehicles are safe and efficient.  

• Public policy experts work with governments to create laws and regulations that enhance transit services and promote public access.

The Future of Seattle’s Public Transit

Seattle’s public transit is always improving, with exciting projects that aim to make the system more sustainable and efficient. King County Metro is adding electric and exploring hydrogen-powered buses, which will help reduce pollution and make the city quieter. 

Eric explained that by studying data—like how many people ride, how much fuel is used, and which routes are busiest—transit engineers can improve the system. These changes help make Seattle’s public transit more eco-friendly, and riding the bus or train to PacSci is a great way to support these efforts. 

Recently, PacSci’s Science on Wheels team celebrated the Line 2 extension in Bellevue, which connects more communities to Seattle’s transit system.  

They showcased interactive exhibits and hands-on activities, illustrating the role of science and engineering in improving public transit. “Our goal is to connect people to STEM opportunities and experiences,” said a team member.   

The Sustainability of Public Transit in Seattle

Using public transit is a key way to support a sustainable Seattle. It helps reduce the number of cars on the road, lowering air pollution and greenhouse gas emissions. The American Public Transportation Association estimates that public transit saves about 37 million tons of carbon dioxide annually in the U.S. 

Buses and trains can transport many passengers simultaneously, significantly decreasing energy use per person. The Federal Transit Administration found that switching to public transit can reduce an individual’s annual carbon emissions by up to 4,600 pounds—equivalent to the carbon sequestered by 100 trees in a year. 

Seattle is also exploring electric and hydrogen-powered buses, which further cut emissions and enhances air quality. Transportation accounts for about 28% of U.S. greenhouse gas emissions, making it the largest source of air pollution. 

Additionally, many transit stops encourage walking and biking, promoting healthier lifestyles. The American Journal of Preventive Medicine reports that public transit users walk an extra 8-33 minutes daily, contributing to improved cardiovascular health.
