Traffic Signals FAQs
Who can we contact regarding a problem with a traffic signal?
Malfunctioning traffic signals should be reported to EPCOR at 780-412-4500.
For inquiries regarding traffic signal timings, citizens should contact 311 with specific details including the exact location of the signal, time of day, direction of travel, etc.
What should drivers do when approaching a malfunctioning traffic signal?
If the lights are flashing red in all directions, drivers should treat the intersection as a four-way stop (that is, drivers stop and then proceed when safe to do so in the order they arrive at the intersection). If the lights are flashing amber in one direction and red in another, then the drivers who have the amber lights have the right of way. If the lights are not functioning at all, treat the intersection as a four-way stop and proceed with caution until the problem has been fixed.
How does the City decide if a new traffic signal should be installed?
If the City does not have recent data on the location of concern, a delay survey and site check will be scheduled and conducted. Once the assessment has been completed, a response to the inquiry is prepared and provided. Any required follow-up action is noted and the scheduled.
What are the criteria for deciding whether a signal is installed or not?
The City evaluates and considers:
- main and side street traffic volumes
- delays experienced by drivers
- impacts of queued traffic
- safety concerns
- performance measures
- implications of signalization on the overall roadway network
Some criteria are rated more highly over others. For example, safety and shortcutting concerns are considered most important, followed by average delay times and vehicle volumes. The evaluation process provides a means of determining whether a traffic signal is appropriate at a given location, and ensures that available resources are allocated to critical locations in a fair manner.
