Traffic Signal Design and Intelligent Transportation Systems

CHS Consulting Group’s licensed traffic engineers are leaders in cutting-edge technologies and current practices. Our traffic engineers have more than 30 years of cumulative experience in the design and operation of traffic signal systems for Caltrans, local cities and counties, and transit agencies. We have unique experience in designing signals along light rail lines (with signal pre-emption for light rail vehicles), red light camera enforcement, signal interconnect involving combined hardwire, wireless technologies (such as spread spectrum radio technology), and areawide traffic signal systems. Our traffic signal systems range from simple isolated intersection signals to complex interconnected areawide or citywide traffic control and management systems. We have harnessed recent advances in computer, vehicle detection, and communications technologies to provide an increased sophistication in all levels of traffic signal planning and design. Engineering expertise in this area requires more than the selection of poles, signal heads, controllers, conduits, and other intersection equipment and their installation details. We bring a thorough understanding of signal operations and state-of-the-art signal controller, vehicle detection, and communications technologies to each of our projects.
