Traffic congestion is a huge problem for many cities and towns worldwide. Not only does it cause frustration among drivers, but it can also lead to increased pollution and accidents. Traffic management in NZ is optimising traffic flow to reduce congestion and improve safety. In this guide, we will highlight the different traffic management methods and how they can help your community!
Traffic signs
Traffic signs are the most basic and commonly used method of traffic management. They are placed at strategic locations to warn drivers of upcoming hazards, give directions, or regulate traffic flow. Traffic signs come in various shapes, and each type serves a different purpose.
Traffic lights
Traffic lights are another common form of traffic management used to control the flow of traffic at intersections. Traffic lights typically have three colours (red, yellow, and green), each with a different meaning. For example, red means stop, yellow means slow down or prepare to stop, and green means go. Traffic lights may also have additional functions, such as pedestrian crossing signals or left-turn arrows.
Traffic barriers
Traffic barriers are physical objects that are used to block or redirect traffic. Barriers can be made from various materials, such as concrete, metal, or plastic. They are typically used to protect pedestrians or workers from oncoming traffic, block off dangerous areas, or redirect traffic around construction zones.
Traffic cones
These are other types of physical barrier that is used to direct or block traffic. Cones are usually made from plastic or rubber and are often brightly coloured (such as orange or yellow) to make them easily visible. They are typically used to mark hazards in the road, such as potholes or debris, and can also temporarily block off lanes of traffic.
Traffic barrels
Traffic barrels, also known as drums, are large cylindrical objects used to block off or redirect traffic. They are typically made from plastic or metal and are often brightly coloured for visibility. Barrels are usually placed in the middle of a lane to block it off, or they may be placed along the side of the road to guide traffic around a curve.
Traffic delineators
These are physical devices used to mark the edges of roads or lanes. Delineators are typically made from plastic or metal and can be rigid or flexible. They may be painted with reflective stripes for improved visibility at night or in inclement weather. Delineators are often used to mark the boundaries of construction zones or detours.
Traffic mirrors
These are reflective surfaces that are mounted on posts or poles. They improve visibility at intersections or other locations where drivers might have difficulty seeing approaching traffic. Traffic mirrors may be convex (curved) or flat. Convex mirrors give a wider view, while flat mirrors give a more accurate reflection.
Traffic cameras
Traffic cameras are video cameras used to monitor traffic flow and enforce traffic laws. Cameras may be mounted on traffic lights, poles, or buildings. They typically record images or videos of vehicles and their license plates. Traffic cameras can detect and ticket speeding vehicles, red-light runners, or other violations.
Traffic sensors
These devices are used to detect the presence of vehicles. Sensors can be placed on the road (such as inductive loops) or roadside objects (radar detectors). They are often used to trigger traffic lights or cameras or to count the number of vehicles passing through an intersection.
Variable message signs
Variable message signs (VMS) are electronic signs that can display a variety of messages. For example, VMS can provide information about traffic conditions, such as construction delays or accidents ahead. They can also be used to display warnings, such as severe weather alerts or Amber Alerts. VMS is often controlled by traffic management centres, which can remotely change the displayed messages.
Traffic management NZ is a critical function in any city or town. Traffic congestion can lead to delays, accidents, and even injuries. By using some of the methods described above, you can help to keep your community safe and moving smoothly.
