  2. Traffic light control and coordination - Wikipedia

    en.wikipedia.org/wiki/Traffic_light_control_and...

    After the newer generations of traffic signals that use LED lights which consume 85-90% less energy, it is now possible to incorporate battery backups into the traffic light systems. The battery backups would be installed in the traffic controller cabinet or in their own cabinet adjacent to the controller.

  3. Signal timing - Wikipedia

    en.wikipedia.org/wiki/Signal_timing

    Signal timing is the technique which traffic engineers use to distribute right-of-way at a signalized intersection. The process includes selecting appropriate values for timing, which are implemented in specialized traffic signal controllers.

    South Dakotans have the shortest commute, with an average time of 17.4 minutes. In the table below, you can see the average drive time to work in all 50 states, Washington, D.C. and Puerto Rico. State

  5. Traffic optimization - Wikipedia

    en.wikipedia.org/wiki/Traffic_optimization

    The above method is primitive real-time signal optimization at best. This method will optimize one traffic signal at a time. However, in the real world, a motorist's commute involves driving through multiple signals. Thus, multiple traffic signals need to be collectively synchronized in order to be effective.

  6. Intersection capacity utilization - Wikipedia

    en.wikipedia.org/wiki/Intersection_Capacity...

    The data needs to include volumes, number of lanes, saturated flow rates, signal timings, reference cycle length, and lost time for an intersection. The method sums the amount of time required to serve all movements at saturation for a given cycle length and divides by that reference cycle length. This method is similar to taking a sum of ...

    en.wikipedia.org/wiki/Sydney_Coordinated...

    The Sydney Coordinated Adaptive Traffic System, abbreviated SCATS, is an intelligent transportation system that manages the dynamic (on-line, real-time) timing of signal phases at traffic signals, meaning that it tries to find the best phasing (i.e. cycle times, phase splits and offsets) for a traffic situation (for individual intersections as well as for the whole network).

    For many, it will mean regularly commuting for the first time since the pandemic forced businesses to shut shop and forced (or allowed) workers to carry out their jobs from the comfort of their ...

  9. Lost time - Wikipedia

    en.wikipedia.org/wiki/Lost_time

    Lost time is the term within traffic engineering for the time during which no vehicles are able to pass through an intersection despite the traffic signal displaying a green (go) signal. The total lost time is the sum of two separate elements: start-up lost time and clearance lost time. Start-up lost time happens when a traffic signal changes ...
