STC Traffic was founded with a clear vision—bringing specialized traffic engineering and Intelligent Transportation Systems expertise to the communities of Southern California. What started as a passion for innovation and problem-solving has grown into a trusted partnership with dozens of municipalities in the region.

Since 2007, our team has delivered creative, real-world solutions to the most complex traffic engineering challenges. We operate as an extension of City staff, providing guidance in traffic engineering, transportation planning, and ITS. Our approach is simple: stay at the forefront of technology, embrace difficult projects, and build a team of professionals who share a commitment to excellence.

What sets STC apart is our people. Our team is a diverse group of specialists—licensed traffic and civil engineers, certified planners, IMSA-certified signal technicians, ITS and network engineers, and former public works inspectors—who work together to provide seamless, start-to-finish solutions. Unlike most traffic engineering firms, we offer a full-service approach, ensuring that projects don’t just get designed, but successfully implemented.

Our work speaks for itself, enabling us to push the boundaries of what’s possible in the field. As Southern California’s transportation infrastructure continues to evolve, STC remains committed to delivering smart, data-driven solutions that enhance mobility, safety, and the quality of life in the communities we serve.
