Frequently Asked Questions

Every signalized intersection has special coordination needs and may require various types of timing depending on a few factors such as traffic volume, speed, direction of travel, time of day. Specific questions about a traffic signal can be directed to the Broomfield Traffic Engineer at traffic-engineering@broomfield.org.

If a signal is changing with no vehicles present, an error with our detection cameras may be occurring. Please contact the Streets Division using this form.

Broomfield does not put signals in flash overnight in order to maintain a more typical condition for vehicles at the intersection over the entire day. One of the main goals is consistency in traffic signals and this helps us achieve this. Overnight signal timing is changed so that they are no longer in coordination to assist drivers in getting a green as soon as possible.

 All of Broomfield's signals are coordinated along the major roadways. Coordination is based on which roadway is the larger roadway classification, directional traffic, and distance between signals. 

 The goal is to have enough green time to clear traffic at all times. During peak times the coordinated roadways which have higher traffic volumes are typically prioritized to move more traffic through the intersection. Some approaches or turn movements may have more delay as a result.

The Colorado Department of Transportation (CDOT) is responsible for all street surface repairs and maintenance including potholes, snow control, and weed mowing and for signal maintenance/timing on state highways within Broomfield's city limits including Hwy 121, Hwy 128, Hwy 287 (a.k.a. Wadsworth Boulevard), 120th Avenue, and Hwy 7, Please contact CDOT directly with any questions or concerns.
