Keeping people and goods moving.

We’re helping clients accommodate growing traffic through better signalization.

In this time of tight budgets, you are looking for ways to accommodate more vehicles on roadways at an affordable cost. Coordinated signalization may be the best route to achieve your goals. Evaluating, designing, and installing signalized intersections and coordinated signal systems can alleviate traffic congestion, minimize delays, reduce pollution via vehicle emissions and improve traffic flow. SEH has taken the lead in evaluating, designing, and installing both individual signalized intersections and coordinated signal systems. Through our expertise in signal design and control, we are able to maximize the benefits of these systems which include reduced congestion, reduced overall delay, reduced pollution and vehicle emissions, improved traffic flow and efficiency (level of service), and accommodation of more vehicles on existing roadways.
