Broomfield plans adaptive signal system to improve traffic light synchronization

During a recent Transportation and Traffic Community Briefing held by Broomfield County, residents raised significant concerns regarding the synchronization of traffic lights on key streets, including Lowell, Sheridan, Maine, Midway, and others. Many drivers reported that adhering to speed limits often results in frequent stops at traffic signals, even when traffic is light. One resident highlighted a specific issue where a single vehicle turning at Hazel Street could trigger red lights for multiple vehicles traveling east on Midway, despite no traffic present at that intersection.

The discussion revealed frustrations over pedestrian crossings, particularly on Main Street, where a single pedestrian could halt traffic for numerous vehicles, raising questions about the efficiency of the current traffic management system. Residents expressed confusion over why they seem to bear the responsibility for monitoring the quality of traffic signal operations.

In response, Broomfield officials explained that the city utilizes a traffic modeling program called Synchro to coordinate major roadways. However, they acknowledged that the optimal timing may not suit every individual vehicle due to various factors, including cross traffic and directional flow. For instance, intersections with high cross traffic, like Midway Boulevard, may experience longer delays.

To address these issues, Broomfield is actively exploring technological improvements, including adaptive signal timings that adjust based on real-time traffic conditions. A pilot project is currently underway to implement this technology, alongside efforts to expand the fiber network for better signal coordination. Many existing signals rely on radio communications, which can lead to synchronization issues.

Additionally, officials announced that the signal timing at Midway Boulevard and Hazel Street will soon be updated in conjunction with a new traffic signal installation at Midway and Elm. This update aims to ensure a more efficient flow of traffic.

Residents were encouraged to report specific concerns regarding traffic signals on Main Street or Lowell Boulevard, as city staff are open to reviewing and improving signal coordination in response to community feedback. The meeting underscored the importance of ongoing dialogue between residents and city officials to enhance traffic management and ensure safer, more efficient travel throughout Broomfield.
