Lighthouse TG completed a citywide upgrade of all signalized intersections in the City of Castle Pines, implementing new flashing yellow arrow (FYA) left-turn signals. This project brought the city’s signal operations in line with current national standards for signal displays, enhancing both consistency and safety across its roadway network.
The FYA upgrades allow for improved driver comprehension while maintaining efficient traffic flow. More importantly, the new configurations now support protected-only left-turn phases during pedestrian crossings, significantly reducing conflict points and improving safety for pedestrians in crosswalks. Lighthouse handled the full scope of the project, including equipment upgrades, signal programming, and coordination with local traffic engineers to ensure smooth implementation and long-term reliability. The result is a modernized signal system that offers both operational efficiency and enhanced safety for all users.
