Traffic lights are part of the necessary infrastructure in every city to be able to order the traffic and movement of people and vehicles in a harmonious way. In recent times, different projects and systems have been developed to achieve ecological traffic lights.
Some of these innovative eco-friendly designs and technologies are:
- Traffic lights in the trees: This design allows a wireless traffic light to be installed with led lights in the trees. Without hurting or altering the normal growth of the tree. The advantage of this technology known as Weareable Signal is that there is no need to place poles that alter the landscape. This type of traffic light is not for just any place but it can be useful for environmentally sensitive areas.
- Solar powered traffic lights: There are models of traffic lights that have solar that provide them with energy to function, which is very useful if they are independent of the power grid Since in the face of a power cut and the non-functioning of the traffic lights, chaos arises in the traffic, which can lead to accidents.
- LED lights for traffic lights: You can replace the incandescent lights that most of the traffic lights have by led lights so that energy is saved but also greatly reduces the CO2 emissions. It is the most economical option since only the lamps are replaced, the rest of the structure remains the same.
Several European cities have already started to use green traffic lights with some of these characteristics, which is very positive since save energy, reduce emissions and above all save a lot of money per year.
A modern and sustainable city must use technology in urban infrastructure with clean energies and that it consumes as little energy as possible in its operation.
The transformation is gradual but we must move towards greener cities in all their areas, starting with the traffic lights is a step.
