Seidor Opentends and AMB implemented the AWS-based cloud-native IoT Low Emission Zone (LEZ) platform in Barcelona in 2017, aiming at improving the city's air quality, and managing available resources and regional assets more efficiently. The LEZ policy restricts the travel of certain high-emission private vehicles within the Barcelona LEZ. Seidor Opentrends delivered AMB a custom system that allows the management of statistical data extracted from the LEZ. Barcelona’s LEZ is currently the largest in southern Europe.

Today’s platform's main features are

  • Integration with DGT (Department of Motor Vehicles) data source to obtain current license plate census
  • Real-time alerts on air pollution levels with the integration of the SCCA system (Air Pollution Control System)
  • Integration with cameras to collect license plate readings
  • Management of exemptions applied to a regional scope
  • Storage of readings and data mining
  • Architected on business logic, separating front-end and back-end layers

Seidor Opentrends’ work on developing and implementing Barcelona’s LEZ has resulted in

  • Increased synergies that contribute to the evolution of an intelligent environment that harnesses data and technology
  • Streamlining the digitalization of regional governance and management

Seidor Opentrends’ work for AMB on the Barcelona LEZ is a global reference in sustainable smart cities’ best practices and IoT cloud infrastructure. 

Working with the public and private sectors, the Singapore government’s vision is to empower the public through technology. We’re proud that our work is a reference for digital governance and sustainability.
