Traffic Engineering

- further categories

Traffic engineering equipment is an essential part of transport infrastructure, designed to manage the movement of people and goods on roads, motorways and other transport networks. The most important traffic engineering equipment includes traffic lights, cones and other signalling devices, as well as road signs, battery-powered road signals, traffic diversion lights and plastic traffic signal cones.

Why are Traffic Engineering needed?

For road reconstruction, maintenance or construction, a wide variety of traffic engineering devices are often needed to ensure that the traffic diversion that occurs during the works is professionally constructed in accordance with road safety regulations.


Traffic engineering devices may also be needed for traffic diversion or traffic closures on roads, motorways, police actions, disaster management and accident prevention. The selection and installation of these devices must take into account the relevant standards and regulations, which are designed to ensure the safety of all road users. It is of paramount importance that traffic engineering devices are visible at night and stand out from the daytime environment, so that they are conspicuous on other dangerous road sections (e.g. pedestrian crossings, busy intersections at schools, residential areas) to ensure that they are detected as soon as possible. Its use is authorised by the competent local authority.

Types of traffic engineering devices

Traffic engineering devices for the provision of road traffic can be of different types according to user needs, for example:

  • indicator lights (installed and manual), beacons
  • distracting buoys, distraction lights
  • message signs
  • portable traffic lights and signs
  • trailers, vehicle-mounted direction indicators, direction-indicator lamps
  • Reflecting tapes and foils


The larger the area to be controlled in terms of traffic, the more it is advisable to choose automated and easy-to-use devices for this task. Another selection criterion is whether to consider a mobile device (e.g.: hand-held beacon, cone, portable traffic light) or a vehicle-mounted traffic engineering device. Typically, traffic engineering devices are equipped with high-power batteries to ensure uninterrupted operations.

Traffic light characteristics

Traffic lights are one of the most visible examples of traffic engineering equipment. They are used at intersections to control the flow of traffic and ensure that vehicles and pedestrians can cross the intersection safely. The traffic lights use a system of red, amber and green lights to indicate when vehicles and pedestrians should stop, slow down or move on at the intersection. Traffic lights are key to preventing accidents and managing the flow of traffic.

When should you use a traffic diversion cone?

Plastic traffic diversion cones are a basic type of traffic engineering device. They are lightweight and durable and can be used to create temporary barriers and to divert traffic around hazards. Plastic traffic cones are easy to transport and can be quickly erected in a wide variety of situations, making them an indispensable tool for traffic engineers and road construction crews.

Advantages and features of traffic lights

Traffic diversion lights are a type of traffic engineering equipment used to indicate when traffic needs to be diverted due to road construction or other hazards. They are usually placed at the entrance to a road or motorway and provide drivers with important information about the traffic conditions ahead. Traffic lights can be essential in preventing accidents and ensuring that traffic can safely avoid hazards.

When should you use a battery-powered beacon?

A battery-powered beacon is a type of traffic engineering equipment that is commonly used in areas where there is no access to electricity. These signals are battery operated and can be used in areas where there is no power source. Battery-powered traffic signals are essential to ensure that traffic signals function properly and provide important information to drivers and pedestrians.

What materials are these products made of and what weather conditions are they suitable for?

In the DND Telecom webshop you will find a wide range of traffic engineering devices, all made from materials that guarantee long-term trouble-free use. But let's look at the details! For example, the signal cone is made of unbreakable polycarbonate with a high refractive white coating. The housing of the traffic light is made of black aluminium and the yellow signal part is made of high-strength polypropylene.


The solar traffic signal cone has a polyurethane plastic signal body, and the traffic signal frame is made of aluminium, on which the manufacturer places the illuminated enclosed profiles. In all cases, the materials used are weather-resistant, so there is nothing to stop them being used when needed.

What colour options are available for Traffic Engineering Equipment and cones?

It depends on the device, but by default the colour of the warning buoy and beacon is yellow. Wearable safety lights are available in several colours, they can be yellow, red or blue, depending on the use. But for example, the solar powered beacon only lights up in red. And the traffic signal can be red, blue or yellow.

What kind of signals, such as colour changes or flashing, can traffic lights give?

Traffic diversion devices available in the DND Telecom webshop have different levels of light intensity and brightness. For example, in the case of traffic diversion lights, which we are used to seeing on motorways and highways, they can display different shapes. The signal panels can be operated manually or by wireless control.

Do you need a specialist to install traffic engineering devices or can they be easily operated and installed by users?

With a portable safety light, the device is simply placed on your clothing. The installation of traffic lights and beacons does not require any expertise, but the installation of solar powered beacons, which are mainly used in airports, and the installation of entry lights are also devices that require a specialist.

How does remote control or monitoring work, if such an option is available?

In the case of trailer-mounted traffic control lights that you may encounter on motorways and highways when a lane is closed, for maintenance, road construction, or in the event of an accident, there is the option to control the signal panels manually or with a controller to display different forms of the device.
