SICE’s SIDERA software was the solution chosen by Mobilitex Tecnologia e Mobilidade, a highly valued company in Brazil, for the management and control of tunnels T1, T2, T3 and T4 in Serra do Cafezal.

On December 19th, ARTERIS S. A., one of the largest road operators in Brazil performing more than 3,700 kilometers, officially opened the tunnels and on December 20th those were opened to the public.

The project includes the centralized management solutions for four tunnels, as well as sub-centers in each of them. Inter alia, SICE has been responsible for carrying out the following items:

  • SICE’s SIDERA software implementation
  • Algorithms implementation for managing fire in tunnels:
    • Pumps and fire control algorithms.
    • Tunnel closure algorithms.
    • Lighting algorithms.
    • Fire algorithms.
    • Drift pressurization algorithms.
    • Ventilation algorithms.

The implemented SIDERA system, which joins SICE’s successful expertise managing tunnels around the world, offers a comprehensive solution providing:

  • Security: SIDERA offers different algorithms that can be activated when an incident or a critical situation arise, such a fire.
  • Control: equipment and alert monitoring allows to have control on the entire installation.
  • Traffic management: SIDERA supplies tools required for an appropriate day-to-day traffic management tailored to the nature of the four tunnels.
  • Data: the automatic vehicle detection and storage of the data generated by the equipment allows to obtain statistics and auditable data from the whole installation.

The list of the equipment implemented amounts to five hundred. Among them, SIDERA monitors and manages the following:

  • Variable message panels.
  • CO measuring equipment.
  • Anemometers.
  • AID system (cameras for automatic incident detection).
  • Permanent and mobile CCTV cameras.
  • Light flux meters.
  • Height detectors.
  • Visibility sensors.
  • Fire protection door sensors.
  • Room temperature sensors.
  • Lighting panels.
  • Energy panels.
  • Energy transformers.
  • Control and command panels.
  • Ventilation system (Fans).
  • Beacons (Signaling lights).
  • Energy multi-measuring.
  • Lighting circuits.
  • Power generators.
  • Gallery fan system.
  • Axial ventilation system (fans).
  • Traffic lights.
  • Tunnel lighting meters.
  • Hydraulic pumps.
  • Emergency call boxes.
  • Valves for hazardous liquids.
  • Signs and indicators.
  • Door sensors.
  • Fire sensor system (chip cable).
  • Air conditioning equipment.
  • Public Address (PA) systems.

The tunnels are 346,216,717 and 381 meters long respectively, and the third one have a 200 meters drift. All the four are one-way tunnels. Three of them lead to Sao Paulo - Curitiba and the fourth Curitiba - Sao Paulo.
