CONTROL SYSTEMS FOR ROADS

The product line devoted to the analysis of pavement – the result of the company’s experience in mapping technologies, the production of means for road maintenance and inventory. Competence derived from more than 10 years of experience in mapping more than 400,000 km.

The company “SV Solutions”, in cooperation with RTU (Riga Technical University), conducts research and is in the process of developing universal software. The data was simultaneously obtained from mobile systems (MLS), georadars (GPR) and unmanned aerial vehicles (BPLA) for their processing.

The mobile mapping system’s road scanner is directly integrated with the new equipment focused on surveying the condition of pavement repair, while the Road-SIT PMS application software has been completely reorganized to ensure efficient management of activities with respect to road assets. The most innovative factor of the solution is the integration into the ESRI ArcGIS system, which provides full control over all data collection and management activities in the context of their mapping. Thanks to this, it is possible to get an idea of the infrastructure as a whole, quickly and conveniently view the existing and planned repair work. Thanks to special features and interfering with management programming, the user can effectively optimize operating expenses and obtain an objective assessment of the quality of possible improvements for coverage.

The solution offered by SV solutions includes:

The sophisticated technology of the road scanner of the mobile mapping system, thanks to which measurements can be carried out even in places with poor or no lighting, for example, in tunnels;

Road-SIT PMS application software, which is fully integrated with the powerful ESRI ArcGIS mapping system, provides monitoring and decision-making features for the analysis of Maintenance programs that are related to Status Indicators;

Additional mapping of longitudinal and transversal roughness, friction, allowable load and/or base sampling in the case of a motorway or on request due to specific infrastructure conditions.

WORKING METHODOLOGY

The methodology has been developed with a fundamental contribution from the University of Bologna – DICAM (Department of Civil, Ecological and Material Engineering). Below are the main theses of the working methodology.

Definition of a complete catalog of surface defects

All road surface defects are pre-classified according to the catalogue defined in ASTM D6433/2003 specifications. Each defect is represented by a measuring parameter and geometric characteristics that determine the severity of defects.

Complete fault mapping with high-performance MMS technique

The dimensional parameters and sensor required for mapping and measurement are defined for each type of defect. A specific application software partially overlays the visual data collected through mapping. For example, with data generated from other sensors, such as dense point sets of a laser scanner. All geometric data of defects are geologically benchmarked and it is possible to make measurements of coordinates, lengths and areas. All data is stored in a geographical database, can be viewed and tested in the GIS environment.

Calculation of maintenance status indicators

In addition to the IRI index mapped to the profilometer, other status indicators are identified in accordance with international standards. Particular attention is paid to the Coverage State Index, which is also taken into account at the national level. The applied calculation algorithms are processed automatically, starting from the fault database, the PCI values for road zones that have a constant length, to provide synthetic data on the maintenance status. This index is then used to provide synthetic notifications for all road assets or for an individual road.

Provision of maintenance status and notifications in support of decision-making

PMS provides synthetic status indices with a GIS environment and displays defects in the circuit, organizing them by type. It is possible to insert representations derived from external sources, such as historical data carried out in the past, traffic data, and also meteorological data.

Maintenance intervention database definition

All interventions that may have been made with respect to road features are summarized in the catalog and divided into two main categories:

General or restoration interventions at different depth levels suitable for dissolving surface or structural defects (e.g. reinforcement, partial reconstruction, restoration).

Specific interventions to restore surface characteristics and functionality of the road surface in case of defects. For example, grambas, filling, patches, filling cracks, partial coating.

The catalogue is adaptable, so it is possible to include interventions according to the needs and work habits of the consumer.

The relationship of road maintenance interventions with road assets

Each intervention is associated with the corresponding section of the path with the help of GIS tools or indicating a specific chain. The choice of the intervention to be performed remains with the designer, who can perform rapid modeling in different zones or for different types of interventions in order to obtain a model and assess expenses. Conversely, if the designer first selects defects that need to be eliminated as a matter of priority, the application software processes the optimal interventions from a technical point of view.

Estimating maintenance expenses and modeling CPI recalculation

The system treats the surface of roads or the calculation of the details of defects for selected routes. Since each intervention is associated with unit expenses, the system calculates the expenditure of an intervention or intervention complex grouped into programs. Based on the selected intervention, the system recalculates the value of the status index. Thanks to this modeling, the optimal choice is based on the economic element and on the technical improvement of the state of maintenance.

Regular monitoring and updating of the fault database

Pavement defects can also be controlled with other types of tools: video systems that are suitable for standard cars or “mobile” systems for accurate checks of demarcated areas.

SOFTWARE

Road-SIT Road PMS consists of 3 modules:

Defect Analysis: It includes, within the GIS editor, the visualization and management of feature mapping data obtained with an MMS path scanner or from external sources.

Maintenance management: It provides a catalog definition of interventions and their organization in maintenance plans, it also calculates the expenses of each intervention or the total expenses of each plan.

Decision-making support: It is specifically dedicated to the production of statistical synthesis statements using data collected in the defect database in terms of calculating the Status Index and modeling various maintenance strategies.
