MANAGEMENT SYSTEMS FOR AIRPORTS
ROAD-SIT CONTROL SYSTEM PACKAGE FOR AIRPORTS
The suite of products for airports has benefited from the development of Siteco’s competency-based mapping technologies and programmatic provision, as well as from the experience gathered and carefully thought out in the road sector over more than 10 years and more than 40,000 km.
Mobile mapping systems The Road Scanner has been integrated along with the new equipment designed to meet and meet the requirements of airport regulations.
The most interesting innovative solution is the integration of ESRI into the ArcGIS system, which provides complete control of all surveying and maintenance activities in the context of mapping. Thanks to this, it is possible to get an idea of the infrastructure as a whole and an immediate consultation on the state of repair, planned and taken measures. With the help of specific functions, the user can plan maintenance measures and effectively optimize both operating expenses and the longevity of the cover.
The effective use of design applies to both the result and the process, emphasizing the importance of design thinking at all levels of decision-making and management, using the 3D scanning method as a basis.
THE SOLUTION PROPOSED BY SITECO INCLUDES:
MMS Road scanner fine technology, which is equipped to provide mapping even at night, avoiding interference with air traffic;
TRoad-SIT PMS application, which is fully integrated into the powerful ESRI ArcGIS mapping system, providing monitoring and decision-making for the analysis of maintenance programs related to the Status Indicator;
Permissible load structures when performing mapping and project analysis.
MODULES SYSTEM
Signs of road-SIT PMS can be classified in the following way:
Danger risk analysis – this module provides advice on data collected using the Road Scanner. This includes high-resolution images, laser scans obtained with the help of the Ground Screening Radar, as well as longitudinal roughness data obtained with the help of a profileometer. This module provides mapping of all functional cover defects recorded in the system relational database, performs monitoring activities, also using “mobile” equipment, such as PDAs, tablets, etc. The coverage condition index is calculated according to ASTM D 5340 standards, and the output values are updated based on the maintenance activities performed and the results of the survey.
Data management system – Road-SIT PMS is designed to extract data collected using various sensors (MMS installed). Also suitable for other types of data obtained as a result of tests carried out on airport surfaces (e.g. friction and permissible load data). According to the available data, the system calculates indicators of specific status for various homogeneous sections of the airport. These sections are divided into constant surface zones. GIS images allow you to perform instant control of various parameters.
Decision Management System – This system includes maintenance technologies used at various airports, allowing you to create a customized maintenance program. Any activity can be associated with the results that can be achieved using the resolution of structural surface defects and the expenses associated with it. By modeling various maintenance strategies, the user can choose the best option for himself. After that, the system ensures the management of all activities to be performed and the recalculation of various indicators of the results of the executed intervention.
WORKING METHODOLOGY
Road-SIT Airport PMS is based on the organization of specific information layers of the GIS system that correspond to all PMS data: vehicle mapping routes, mapping determinants and permissible loads for surveyed areas, PCI zones, corresponding mapping data and their processing. The GIS system also provides a definition of zones that categorize airport infrastructure according to a precise hierarchical organization.
INFRASTRUCTURE BREAKDOWN AND HIERARCHICAL ORGANIZATION
For rational maintenance of the pavement, all covered surfaces are divided into different zones based on the hierarchical principle of different levels, known as the Pavement Grid Map. The first level consists of operating areas (branches), which have various functions: runway, carriageway, connections, parking, service roads, etc. These zones, in turn, are divided into Homogeneous sections, i.e., sections with similar design features:
Construction period;
The thickness of the screed and the status of the permissible load;
Traffic and the level of general load.
This division is essential to define the decline curves of each section and to decide on the maintenance activities to be performed.
Each section is further divided into adequate zones of constant area (300-400 m²) in the number of elementary zones, which are defined according to various indicators that are associated with them (PCI, roughness, permissible load, friction, etc.). For each zone, the destruction indicator is assessed for a number of structural or functional aspects.
Mapping a road scanner
The trajectories performed by the MMS pathway scanner are recorded in an additional layer, making it easier to advise on the data collected. These trajectories provide identification of the cartography of the route displayed in the photographic database, which is being reviewed, and vice versa, it is also possible to select the most suitable photographic database and check the area. The surface of the airport is covered by a road scanner vehicle on parallel routes at a distance of 4-5 meters. As for runways and roadways, the direction of mapping is controlled by a special programmatic provision that helps the driver maintain a constant direction.
Map surface degradation status
Defects are classified in the catalog according to the specifications of ASTM D6433/2003 with the help of a special menu that allows the user to access the level of rigidity. One of the most interesting components of the proposed methodology is the visual detection of defects, which is facilitated by reviewing the data obtained by profilometers and laser scanners. The photographic database interface integrated with GIS ArcView ensures optimal navigation across all mapped data and fault database. At all stages, the operator can check the activities performed in the mapping system.
All detected defects are represented in an additional layer that refers to the associated geometry (for example: hole points, broken cracking lines, cracking polygons, lows, grooves). Based on defects that are wholly or partly attributable to the CPI zones, it is possible to calculate the corresponding indicators and display them in accordance with the limit values of the ASTM specifications. The application software also allows you to view the surface defects of each individual PCI zone.
View maintenance status
All mapping results are displayed in ArcGIS and can be immediately displayed on the map display or rendered numerically. In this way, it is possible to represent the characteristic permissible load values (PCN/PDO, flexible modules, layer thickness), PCI indices, longitudinal irregularities, etc. Thanks to this type of representations, intervention activities can be carried out quickly and efficiently.
Manage the intervention catalog
With the help of this application software, it is possible to define different management catalogs. The available databases can be integrated by applying the Tendera specification. Each catalog allows the user to organize interventions by type, such as structural or functional intervention, reconstruction, or localized intervention. The programme has the dual objective of improving the organisation of interventions and, at the same time, of providing a framework with methods for calculating the costs of each intervention. For each intervention, the user can define the expense per unit and clarify the lists of defects, since the intervention can also solve any residual defect after maintenance.
Breakdown of interventions according to coverage
In order to analyse the expenses and extend the life of the surfaces covered by the airport, it is necessary to select the zones and/or homogeneous sections to which a specific intervention method should be assigned. This assignment can be done by selecting a schedule in GIS programs or by filtering zones and sections through appropriate queries in the database according to priority criteria. In this way, you can create a maintenance plan that contains maintenance for interventions that are selected in the catalog. If the same intervention belongs to different planes, the BPS operator can define different maintenance plans and compare them by expenditure, time allocation and useful life of the infrastructure.
Decision support tools and Deceleration curves
The system also provides tools to support decision making by modeling various maintenance strategies, CPI calculation, and derived subsidence curves. Special features allow users to assign subsidence curves to homogeneous sections, as well as define a time chart. It is then possible to compare the theoretical subsidence curves with those derived from the observations made during the monitoring phase. Based on these results, it will be possible to calibrate the curves of different homogeneous sections.
