Today, the repair and construction of highways and roads have increased, and at the same time, concerns for the safety of passengers and road construction workers in these conditions have also increased, because there is always a possibility of car accidents when working on the roads. There are also accidents with each other and pedestrians. Fixed traffic barriers are important tools to help protect workers and pedestrians by controlling the traffic flow in the workshop area, and thus the entry and exit of vehicles from the traffic area will be provided safely for workers.

Generally, there are several models and types of traffic barriers, the most common of them has a gate shape and has a frame, and several boards. In the European Union and the United States, a type similar to it is used, which has an A shape, and light-colored wooden boards (usually orange and white) are placed on them so that they can be easily seen. Usually, written signs such as the route is blocked or the road is closed is also used along with it. There are different types of fixed traffic barriers, which are sometimes used together with flashing lights, rotating lights, and danger signs to close the road, drilling operations, traffic control, and other safety-related purposes.

Of course, when defining the roadblock, it should not be confused with the entrance and exit gates with roadblocks, which are also called roadblocks for short.

How many types of normal traffic barriers are there?

When defining the roadblock, it should be kept in mind that this device is one of the traffic equipment that is portable or fixed, and usually, one to three boards have traffic signs or attention-grabbing signs to inform the cars of the upcoming danger. There are three common types of fixed traffic barriers, and each of them conveys a different message. These traffic equipment can be folded for transportation. It should also be kept in mind that these devices should collapse when a car collides with them and should not be thrown in the form of projectiles and in a dangerous manner.

Type 1 fixed traffic barrier has only one panel

Type 1 fixed traffic barrier: Type 1 barrier is a folding barrier that has only one warning panel and generally has a width of 60 cm and diagonal white and orange stripes at an angle of 45 degrees. Sometimes, in the base part, a section without visual and simple signs is added to these roadblocks, just to help make it more stable. This fixed traffic barrier can be made of wood or plastic. Due to its folding design, this device can be stored quickly and easily without occupying much space. This type of roadblock is usually used for pedestrians and roads with low-speed traffic.

Type 2 fixed traffic barrier: This fixed traffic barrier is also foldable like the Type 1 traffic barrier and collapses easily when faced with a collision. The only difference is the presence of two warning panels with an attention-grabbing color. This fixed traffic barrier gives better visibility at night, so it is suggested to use this device on highways and roads with faster traffic considering that it is easier to see.

Fixed traffic barrier type two has two panels

The three-type fixed traffic barrier has three panels

Type 3 fixed traffic barrier: The type 3 fixed traffic barrier is larger and has three warning panels. These barricades have a width of at least 120 cm and are often used to block roads because their size and visibility are greater. Usually, this type of roadblocks is used at the end of roads, blocking roads, next to heavy equipment, and during traffic control along with other traffic control equipment. The material of this type of traffic barricade is wood, plastic, or metal, and they can have a 360-degree warning light for more warning. Also, both sides of these barricades usually have shiny and attention-grabbing strips that bring higher safety.

Situations where fixed traffic barriers are used

Situations, where fixed traffic barriers are used, are cases where the traffic of cars and pedestrians on the road or crossing is dangerous even with caution. Among these situations are the following:

  • -On the roads where construction activities are carried out and construction debris has been dumped on the road and the passageway has not been closed.
  • -Areas where electricity supply and cabling operations with a voltage of more than 600 volts are being carried out.
  • -Areas where electrical operations are in progress and live parts of devices are exposed to contact.
  • -The working range of cranes and other cases in which a heavy and deadly device is swinging is a pedestrian or traffic crossing in the swinging range of this device.
  • -Any place on the road where road construction equipment and other equipment are left unattended at night.
  • -Excavation operations and open pits resulting from it
  • -Areas that are considered for demolition operations and explosions with ammunition (such as the destruction of buildings and mines) and no person should be present in these areas.
  • -In the areas of the streets where the sewer doors are open
  • -Areas where construction operations are carried out in areas of high-pressure electricity.

Generally, the fixed traffic barrier does not have only one fixed material, and different forms of them are made of plastic, metal, wood, etc.
