Traffic and Intelligent Transportation Systems

Congestion has grown substantially in our nation’s metropolitan areas over the past 20 years. During this era, the travel time reliability of our infrastructure has become more volatile and less consistent. Each and every day, key considerations that contribute to the quality of life for millions of Americans are compromised or diminished as a function of traffic congestion, delays or safety concerns. 

CHA’s traffic team functions as a “firm within a firm,” providing planning, analysis, modeling, and design development for all types of transportation, aviation and municipal client initiatives. Our team of traffic engineers, transportation planners and technical staff provide a comprehensive breadth of knowledge and experience in all facets of modal mobility, accessibility, safety, technology and deployment. From roadside sign inventories and safety audits to the latest intelligent transportation system (ITS) innovations and applications, our professionals are adept at delivering the entire design development and implementation process.
