Tunnel Management

OPENPARK provides a complete engineering consulting services for the design and implementation of tunnel management system covering all light current solutions required for tunnel safety and traffic management.
ITS is a vital part of tunnel management, as it allows tunnel operators to quickly manage traffic without the risk of human errors, in many cases based on automatic traffic monitoring. Important systems and tools for traffic management include traffic models that determine management strategies, systems for traffic signaling, systems for traffic notifications (VMS), and systems for emergency and incident response.
Our solution includes the equipment and services required to implement a complete infrastructure for networking and communication and control for the whole tunnel management system according to the pyramid structure described below:

Field level equipment (Level O)

Field level equipment are either connected to analog inputs/outputs, digital Input / outputs or serial interfaces of distributed control Remote Terminal Units (RTUs) or directly connected to the IP infrastructure Industrial Switches.

The projects scope includes the implementation of 2 control rooms at both sides of the tunnel with equipment in each one capable of managing the full system in a disaster recover mode. The equipment includes the following hardware items:

  1. Servers in each of the 2 control centers: (3 in each center, total 6 servers)
    • Network Video Recording Servers and Storage Disk array (90TB)
    • FLUX AID and Traffic data collection servers
    • SCADA servers in hot standby mode
  2. Workstations equipped with triple monitor as follows (5 in each center total 10 WS)
    • 2 x SCADA workstations (one for each tunnel) total 2 in each center
    • Voice workstation for telephone attendant console, Radio VBI and Public address with desk microphone and speakers.
    • Administrator and Engineering workstation for SCADA engine (WINCC), network management,
    • Administration workstation for configuration of CCTV, AID, video playback and reporting, and Access control configuration and card registration.
    • Telephony system management and access control server workstation
  3. Video wall Controller and 8xLCD panels 46“ (8 panel in each center total of 16 panels)
  4. IP PABX and IP phones for control centers, and Roadside phones)
  5. Racks and local LAN, firewall and NTP
  6. Console & Chairs, and site preparation

Supervision & Operation Control Room software (Level 2)
