Engineering Safer, More Reliable Transportation Networks

KCA’s Traffic Engineering team combines deep technical expertise with practical, real-world solutions to improve safety, mobility, and operations across the Southeast. Our professional traffic operations engineers and planners deliver innovative approaches that address congestion, enhance multimodal performance, and resolve deficiencies at intersections, corridors, and regional networks.

We support both public- and private-sector clients with a full spectrum of traffic services from small-scale traffic impact studies to corridor evaluations and complex interchange analyses. Our team has completed numerous transportation and planning studies for DOTs and local governments, applying rigorous methodologies to guide informed planning and design decisions.

Trusted by Agencies for High-Quality Traffic Engineering

Our capabilities include trip generation and distribution; LOS/capacity analyses for intersections, arterials, and freeways; and merge, diverge, and weaving evaluations. We also develop hundreds of traffic design plans each year, including signing and pavement markings, signalization, lighting, and intelligent transportation systems (ITS).

Equipped with leading software tools such as CORSIM, Synchro/SimTraffic, and HCS7, our engineers deliver accurate modeling, defensible results, and high-quality documentation. With a long history of repeat clients and strong performance ratings, KCA continues to implement innovative, cost-effective traffic solutions that help agencies and communities achieve their mobility goals.
