Traffic + Safety

Our traffic services team helps clients improve transportation infrastructure and traffic operations systems that support transit and emergency service and other modes of transportation.

We provide a full range of traffic engineering services, from traffic impact studies, corridor studies, traffic signal studies and design, traffic safety evaluations, road safety audits, and access management plans to traffic operations models, urban interchange and intersection design, roundabout design, and funding applications for a variety of traffic improvement projects.

In collaboration with our geometric engineers, we can tackle both the complex urban environment and the rural setting; thus developing cost-effective solutions for interchanges, rural expressway intersections, arterial intersections, or county roads. During collaboration, we identify the safety or operational elements of concern and implement innovative geometric or technological solutions to remedy them.
