Traffic Signals Make Transportation Safety and Traffic Flow Possible.

GHA’s traffic signal design experience ranges from ADA pedestrian safety improvements to multi-traffic signal corridor long improvement projects. GHA can study locations to recommend future improvements, design the new traffic signals, assist with resident engineer duties during construction, and even assist with signal operations after the traffic signal is built. Our experience with all phases of construction and maintenance of a traffic signal and roadway corridor allows us to design projects with their full life cycle in mind. Also, our close relationships with IDOT and other DOTs give us insight into design criteria and preferences, allowing us to truncate the review process

For more than 30 years GHA has provided traffic signal design for a variety of projects ranging from simple ADA pedestrian safety improvements to corridor improvements for entire traffic signal systems. GHA has been selected for Various / Various design contracts by IDOT and designed multiple corridor interconnect and signal replacement projects for LCDOT. GHA has the experience and ability to review the existing operations of an intersection and make recommendations to maximize the improvement budget by focusing on the changes that make a difference in real world operations. GHA can assist with new and modified traffic signals from concept through construction: completing warrant studies, design for new and modified traffic signals, provide resident engineer duties during construction, and even assist with signal operations after the traffic signal is constructed. Our experience with all phases of construction and maintenance of a traffic signal and roadway corridor allows us to design projects with their full life cycle in mind. Lastly, our close relationships with IDOT and other DOTs give us insight into design criteria, preferences, and ever-changing regulations, allowing us to maximize our efficiency and help mitigate potential for additional reviews.
