Highway traffic signal operations engineers are responsible for ensuring the safe and efficient operation of traffic signals that regulate the flow of vehicles on highways. To do this, they must be knowledgeable in areas such as traffic engineering principles, signal timing, roadway design, and emergency operations. By evaluating current traffic conditions, traffic signal operations engineers can determine the best possible signal timing for any given situation to minimize congestion and increase traffic flow.

This optimization of signal timing has a direct effect on highway safety, as it can help reduce the number of accidents by increasing the speed of traffic and reducing the risk of collisions. traffic signal operations engineers are responsible for creating and maintaining emergency plans in case of any unanticipated or hazardous circumstances that may arise on the highway.
