Roundabouts & Traffic Mobility

Traffic got you pulling your hair out? Us too! Check out the ways we are working to ease your drive. ​

Innovative Technologies

New products and practices already in place include:

  • Traffic control fees to reduce impacts to the public — Fees to encourage expedited and efficient use of lanes, sidewalks, and road closures to help minimize the impact on the traveling public.
  • In-pavement solar lights — Used to enhance the safety of the “S” curves on Quebec Street north of 138th Avenue, the city installed solar-powered in-pavement lights on the curves to help illuminate the path for vehicles.
  • Flashing yellow arrow deployment — Used to reinforce the left-turning traffic requirement to yield to oncoming traffic at a traffic signal. The configuration of the flashing yellow arrow signals also allows for switching to a left turn on green arrows only during certain times of the day to enhance safety further.
  • Decorative crosswalk markings — Highly visible decorative pattern crosswalks are used to improve driver awareness, pedestrian safety, and street aesthetics. High visibility crosswalk markings are generally strongly preferred over decorative markings because they are easier for motorists to see.
  • Roundabouts — A specific type of circular intersection designed to reduce vehicle conflicts and control speeds. Roundabouts result in fewer collisions than standard intersections.

Staff is constantly researching other products and practices including:

  • Bluetooth Technology — Bluetooth readers at intersections will allow staff to monitor traffic congestion in real-time, generate travel time reports, and monitor overall corridor performance.
  • Traffic signal countdown timers — Partnering with in-vehicle app developers to provide in-vehicle displays of traffic signal status and a countdown from green to yellow or red to green.
  • Intersection Detection Cameras — Technology used to detect bicycles and vehicles at intersections.
  • Intersection Road Configurations — Green pavement markings to assist with moving bicycle traffic safely through an intersection.

Traffic Counts

A traffic count is a count of vehicular or pedestrian traffic conducted along a particular road, path, or intersection. A traffic count is commonly undertaken either automatically (with the installation of a temporary or permanent electronic traffic recording device) or manually by observers who visually count and record traffic on a hand-held electronic device or tally sheet. Local councils can use traffic counts to identify which routes are used most and improve that road or provide an alternative if there is excessive traffic. Also, some geography fieldwork involves a traffic count. Traffic counts provide the source data used to calculate the Annual Average Daily Traffic, the common indicator for traffic volume. Traffic counts are helpful in comparing two or more roads and can also be used alongside other methods to find out where a settlement's central business district is. Traffic counts that include speeds are used in speed limit enforcement efforts, highlighting peak speeding periods to optimize speed camera use and educational efforts (Wikipedia contributors.

Not everyone is lucky to have a six-minute commute, which is why we work with the DRCOG to reduce traffic congestion on major roadways in the metro area. Visit DRCOG's Traffic Operations Program website to learn more about the following:

  • Traffic Signal System Improvement Program:
    • A capital improvements program that provides equipment and installs communication links to improve overall system capabilities.
    • A traffic signal timing improvement program provides new traffic signal timing and coordination plans to demonstrate the benefits of the improvements.
  • Regional Benefits of Completed Projects by Year:
    • Annual Benefits Summary of Projects
    • Signal Timing Briefs

This brochure, prepared by DRCOG, provides a look at some of the challenges involved in improving traffic signal timing and coordination.
