AMB IMPLEMENTS OPENTRENDS’ CLOUD ARCHITECTURE TO MANAGE THE BARCELONA LOW EMISSION ZONE

AMB implements the Low Emission Zone (LEZ) in Barcelona, which aims at improving the city's air quality, and manages it with the own-developed cloud architecture of Opentrends. As of today, Barcelona’s LEZ is the most extensive in southern Europe.

CHALLENGE
A System for data management and exploitation

AMB needed a system that would allow the management of statistical data extracted from the Low Emission Zone of the Barcelona Metropolitan Area (referred here as AMB).

This data is currently provided by various systems such as:

  • Cameras distributed in several municipalities of the metropolitan area conducting constantly vehicle license plate readings;
  • License plate data provided by the DGT (Dirección General de Tráfico);
  • Real-time alerts on air pollution rise by AMB SCA.

More than two hundred European cities in ten countries such as London, Berlin or Paris have already implemented low-emission zones with restrictions on the most polluting vehicles to preserve the health of their inhabitants.

SOLUTION
AMB-ZBE, a platform under AWS

Opentrends has implemented AMB-ZBE, a web platform that manages statistical information related to the Low Emission Zone of the Barcelona Metropolitan Area (AMB).

Platform main features are:

  • Integration with the DGT data source to obtain current license plate census;
  • Integration with the SCCA system (Air Pollution Control System) for detecting pollution episodes;
  • Integration with cameras to collect license plate readings;
  • Storage of readings;
  • Sanction criteria management applied to a territorial scope;
  • Management of exemptions applied to a territorial scope;
  • Data mining.

Currently, 36 of the 66 cameras that the city of Barcelona will have are installed to record and contrast the license plates information with the vehicle database of the General Directorate of Traffic (DGT). The roadmap is to have about 200 cameras distributed throughout the ZBE of the AMB.

Technology

Opentrends has based its solution on SDA (Software-defined Architecture) architectures that are especially suitable to be implemented in cloud environments.

SDA's goal is to provide:

  • An efficient use of resources, providing reduction of CAPEX;
  • Agility in provisioning and resource allocation, providing rapid service delivery;
  • Automated operation, providing maintainability and OPEX reduction;

With the backend services using JAVA Spring APIs and REST frontends (Spring boot) using Bootstrap / React JS frameworks, we have built the cloud-native platform with a known and proven technology stack.

Logical Architecture

 

The Amazon Cloud (AWS), one of our close partners, has been implemented to promote the use of services from this platform, in line with our SDA approach.

This solution fully supports and takes advantage of the AWS’ infrastructure and full PaaS potential:

  • Amazon CloudFront
  • Amazon API GW.
  • Amazon Kinesis
  • Amazon QuickSight
  • Amazon Lambda
  • Amazon Aurora Serverless

It is a 100% Serverless project.

RESULTS
Opentrends' Cloud architecture that will improve the quality of life of the citizens in Barcelona

Thanks to Opentrends' implementation of the cloud architecture, AMB not only achieves a technological advantage, but also makes an impact on society. Here are some examples:

  • Being at the forefront in Europe regarding the use of new technologies such as IoT and Cloud;
  • Manage and exploit the data from the license plates of 1.5M vehicles that are expected in a day, as it is the largest Low Emission Zone in Europe today;
  • Improve the air quality of the citizens of Barcelona.

At a technological level, the milestones achieved by Opentrends with the development of the AMB-ZBE project are:

  • Availability, scalability and performance;
  • Architecture oriented to business logic;
  • Separation of business and frontend layers;
  • Development with autonomous and transversal teams;
  • Ease of application maintenance.
