Smart Cities solutions

A low emissions zone (LEZ) is an urban area in which vehicle access, circulation and parking restrictions are applied to improve air quality and mitigate greenhouse gas emissions , in accordance with the classification of vehicles by its emissions level in accordance with the provisions of the current General Vehicle Regulations.

Current legislation in Spain

Law 7/2021, of May 20, on climate change and energy transition establishes that municipalities with more than 50,000 inhabitants, municipalities with more than 20,000 inhabitants when the limit values ​​of the pollutants regulated in Royal Decree 102/2011 are exceeded. , of January 28 and the island territories will adopt sustainable urban mobility plans before 2023 that introduce mitigation measures that allow reducing emissions derived from mobility, including the establishment of low-emission zones before 2023 and the establishment of specific criteria to improve air quality around schools, health centers or other particularly sensitive centers, when necessary in accordance with air quality regulations.

At the end of the year, the Executive approved the Royal Decree that regulates these emission-free areas and in which it sets out  general guidelines  that serve as a guide for the territories that have to implement them, in order to establish clean and sustainable transport in cities. facing 2030 and, subsequently, 2050.

Zona de Bajas Emisiones



A switch is a network device that allows several devices to be connected to the same network.

In the context of low emission zones, switches can be used to control access to the zone for vehicles that do not meet emissions requirements. The switch can be connected to a license plate recognition system, which can identify non-compliant vehicles. When a vehicle does not meet the requirements, the switch can block access to the area. This will help reduce air pollution and improve the quality of life of citizens.

Advantages of using a switch in a low emissions zone:

  • It is a cost-effective and efficient solution.
  • It is easy to install and maintain.
  • It is flexible and can be adapted to different needs.
  • It is a safe solution, as it helps reduce the risk of accidents.

At Matrix Electrónica, we offer a wide range of switches that meet the most demanding requirements.
