Different Kinds Of Traffic Control Devices

Traffic control devices are signals and marks that are placed on various parts of roads, streets and highways to allow for safe and efficient movement of traffic. They are placed in strategic locations that allow for the best view if them so that they can properly guide the traffic movement, control the speed of vehicles and also warn road users of any hazards or disruptions on the road. They can also provide information on any detours that users have to take due to reasons such as road repair. The most important location of these devices is at intersections where enough signs must be placed so that users can understand the information but not get distracted. Drivers have to keep their eye on the road and will have a limited slot of time to read any signs and process it so the message should be very clear. All devices are made with specific colors and shapes according to their function which is to guide or warn the users. There should be consistency in the design of similar devices so that they are easily recognizable. They should also be visible at night by using reflective material that will bounce light from the vehicle’s headlights. Signs that have a standard shape help trigger their recognition which allows the user to respond immediately. Traffic control Sydney can only be maintained if the devices are placed in locations that give the drivers enough time to read them and understand their message and then take the proper action such as changing their route or departing a road. Visibility is also an important factor and signs should be as brief as possible with large text. 

There are many different kinds of traffic control devices that are placed on the road:

  • Road signs are a common sight and are used to regulate traffic by informing users when they need to stop and what speed limit they need to adhere to. The length of the road will also determine other signs that will be placed such as merging points and U-turns. There are also warning signs that display messages about slippery roads or pedestrian crossings. Informatory signs indicate attractions that are located further down the road such as rest areas or restaurants.
  • Traffic signals direct traffic and are usually placed at intersections to inform opposing sides when they can and cannot move forward.
  • Road markings are glued to the road and consist of reflectors and symbols on the pavement or side of the road.
