What We Do

Engineering

KOA has a reputation for innovation and leadership in the design and engineering of transportation systems throughout Southern California. For the past 30 years, we have demonstrated engineering leadership in all aspects of our streets and highways including traffic signals, intelligent transportation systems, communications, signal timing and operations, street lighting, intersection design, highway design, parking, worksite traffic control, active transportation and complete streets, transit systems, ADA compliance and systemic safety analysis reporting.

We have worked for nearly every municipal agency in Southern California and also provide on-call services for many of them. Our designs and plans are known for their high quality and cost-effective use of resources and budgets.

Planning

KOA’s transportation planning team balances the needs of all aspects of the transportation system in every project we undertake, applying and developing the best practices in the industry. Our planners and engineers develop ideas and solutions that work as well on paper as they do once constructed. Our solutions to planning issues incorporate mobility, urban design, and sustainability to benefit the rapidly changing world of how we live, work, play and travel. Our goal is to plan transportation systems that promote safety and alternate forms of mobility such as pedestrian, bicycle and transit, to provide a comprehensive reduction on the impacts of motor vehicle traffic.

Active Transportation

At KOA, we believe that active transportation planning and engineering design can play a tremendous role in creating safer, healthier, and more equitable communities. Through our efforts in planning and designing, we have developed a diverse portfolio of active transportation projects over the years, many of which have since been constructed. We have witnessed first-hand the transformative nature of active transportation projects on communities across Southern California.
