Integrated Motorway Management System for Aegean Motorway, Greece

Project Overview

Telegra implemented an Integrated Motorway Management System (IMMS) for Aegean Motorway S.A. in Greece using the topXview™ platform.

The system supports the operation of a motorway management environment covering more than 230 km of highway, 4 long dual-tube tunnels, and more than 20 technology subsystems including traffic systems, tunnel SCADA, maintenance systems, CCTV, traffic detection, weather monitoring and forecasting, emergency roadside telephones, VMS, lane control signs, and other field infrastructure.

Client Challenge

Aegean Motorway’s Motorway Management Center was responsible for operating a complex motorway and tunnel environment where multiple traffic, SCADA, maintenance, and operational subsystems were not functionally integrated.

Each subsystem had its own server infrastructure and its own Human Machine Interface (HMI), which created operational complexity and overloaded operators with unfiltered and unprioritized sensor data, event data, and system alerts.

The main goals of the IMMS implementation were:

efficient management of open-road and tunnel systems through one platform,
reduction of operator errors by avoiding unnecessary manual steps,
support for O&M procedures and incident response plans,
easier integration of new equipment and motorway systems,
integration with the organization’s asset management system to connect traffic operations with other non-traffic management processes,
lower operational costs by replacing or integrating several expertise-demanding systems into one platform.

Telegra Solution

Telegra delivered a phased integration and development project based on the topXview™ platform.

The implementation included:

integration of open-road equipment,
integration of tunnel SCADA systems,
integration with existing operational systems, business logic, operations, and asset management,
implementation of Event Management and Decision Support System capabilities.

The implementation was carried out while Aegean Motorway’s field assets remained continuously available and operational.

System Scale

The system integrated a large number of motorway and tunnel assets, including:

85 CCTV cameras,
426 tunnel cameras,
200 emergency roadside telephones,
260 tunnel emergency roadside telephones,
34 road traffic controllers,
268 road traffic detectors,
6 weather stations,
36 variable message signs,
24 LCS / VSLS gantries,
40 queue signs,
8 standalone VSLS,
10 over-height vehicle detectors,
22 gate barriers,
80 monitored vehicles,
150 network devices,
more than 150,000 integrated I/O points.

Integrated Subsystems

The IMMS integrated multiple traffic, tunnel, safety, and operational subsystems, including:

Traffic Data Collection System,
CCTV,
Road Weather Information System,
Automated Video Incident Detection,
Emergency Roadside Communication System,
Over-height Vehicle Detection,
Automated Vehicle Location,
Driver Information System,
Public Announcement systems,
Closure equipment,
Tunnel ventilation,
Tunnel lighting,
Tunnel fire detection,
Tunnel fire fighting,
Power distribution,
Network management,
Equipment health and status monitoring,
Open-road lighting management,
Data management and archiving,
System simulation,
Incident Management and Response Generation.

Event Management & Decision Support

A central part of the project was the implementation of highly customized Event Management and Decision Support System capabilities.

The system supports operators by presenting information in the spatial, temporal, and procedural context of an incident. During incident handling, the system can use relevant nearby data such lighting condition, weather data, pavement condition, road configuration, available patrol vehicles, and closest external response services such as police, ambulance, fire department relevant for efficient resolving of the traffic situation.

The system supports operators by presenting information in the spatial, temporal, and procedural context of an incident. During incident handling, the system can use relevant nearby data such as lighting condition, weather data, pavement condition, road configuration, available patrol vehicles, and nearby external response services such as police, ambulance, fire department, and road maintenance teams.

The Decision Support System helps reduce operator workload by:

guiding the operator through incident-response procedures,
proposing strategies based on encoded procedures and real-time traffic conditions,
recording operator actions and decisions,
checking validity of actions,
minimizing manual steps,
pre-filling available data,
selecting relevant sensor data in the context of an incident,
supporting continuous improvement of O&M workflows.

During incident handling, the system automatically updates historical databases, generates incident reports, and maintains a searchable event history for audit, reporting, and post-incident analysis. Historical events can be searched and filtered by event status, event type, priority, route, location, time period and similar.

Integration with Operations and IBM Maximo Asset Management

Using the topXview™ API, interfaces with existing systems were established. Part of the business logic was moved into topXview Asset Management and Event Management modules.

During incident handling, the system automatically records damaged assets, starts maintenance schedules, and updates public traffic information.

The solution supports:

Integration of employee directory data, including roles and contact information,
Integration and synchronization of the organizational phone directory, including employees and relevant external stakeholders,
Integration of patrol vehicle inventory and real-time vehicle location exchange,
Integration and exchange of patrol vehicle assignment data,
Integration of personnel shift data and on-duty rosters,
Support for assigning the nearest patrol vehicle during incident handling,
Issuing requests for incident data supplementation to non-operator personnel.

Operational Impact

The implementation helped Aegean Motorway migrate from multiple isolated systems into a single integrated operational platform.

Documented outcomes include:

one platform for open-road and tunnel system management,
reduced need for operators to consult multiple applications,
fewer manual steps during incident response,
better filtering and prioritization of operational information,
rule-based VMS/LCS response plan composition by chainage range and sign type,
integration of tunnel SCADA into topXview™,
integration of AVID alarm handling and video wall control,
traffic-data-based incident detection using MARZ and California algorithms,
integration of VoIP and AVL systems,
support for prediction of dangerous weather and traffic situations,
real-time Level of Service calculation,
improved safety management and operational consistency.
