On the Road
to Innovation
The fully integrated solution for the Laser
Mapping and the Pavement Surface Inspection
Founded in 2000 as a software house, focused on GIS and RDBMS, dedicated to Road networks mapping and asset management;
In 2005, Siteco started developing its MMS technology, by surveying more than 50.000 km
In 2012 Siteco introduced its turnkey MMS Road-Scanner3 and in 2014 the Road-Scanner4 systems, distributed worldwide.
Since 2015, system and software unit of the Gavio group, one of the most important financial and construction groups in Italy, reported in the Milan Stock Exchange company list.

SOFTWARE Solutions
The FIRST 360-degree infrastructure and pavement surface inspection system available on the market
PAVE-Scanner
PAVE-Scanner comes from the full integration of thePavemetrics LCMS vision system technology, onto theSITECO Road-Scanner hardware and software platforms
The system includes a complete set of sensors to acquire all theinfrastructure geometry and the pavement features at the sametime
The synchronization with the powerful inertial system allowsperfect geo-referencing of all the acquired information
Laser Mobile Mapping + LCMS
The Road-Scanner system is seamlessly integrated throughout theentire hardware implementation and software workflow, resulting ina totally turnkey commercial system.
The latest LiDAR sensors from FARO, Riegl, Velodyne, Z+F, for 3Dinfrastructure measurement are fully supported.
Wide variety of imaging cameras supported, including the popularPoint Grey LadyBug 5
Top quality Inertial Measurement Systems from Applanix and IXBLUE
PAVE-Scanner : HARDWARE
Combined, the rich data and image information make an easy jobof identifying and cataloging features in a flexible scalablegeodatabase.
All the features are Automatically Georeferenced and stored in theGeodatabase
For the pavement defects, the feature extraction is fullyautomated thanks to the LCMS Software development kit
For the road-side assets the extraction is managed through theRoad-SIT Survey software suite, managing imagery and pointclouds in the same environment

Examples of images and defects
Road-SIT AM – Road Asset Management systemAsset Management System
The new PAVE-Scanner system has been developed together withthe dedicated PMS-SIT software suite suitable for both road andairport pavements.
The post-processing software allows a fully automated productionof all the georeferenced data sets: spherical imagery, point clouds,hi-resolution pavement, 3D bit-maps, transverse profiles, rutting,IRI and Macrotexture data, cracking and other pavement defects,PCI (ASTM standards) .
Based on a GIS environment, PMS-SIT provides the contextualconsultation of all the data sets and a full control of themaintenance status.
PMS-SIT
PMS-SIT Pavement Management System
• Developed in compliance with the Italian National Authority for Civil Aviation (ENAC)
• Already in use in 3 Airports :
PMS-SIT
• The application has a GIS interface, enriched with specific features for analyzing the data derived from the survey and the subsequent processing.
• All information is stored in an appropriately structured relational Microsoft SQL database.
o ESRI ArcGIS Plug-in
o Capable of processing the data collected with any Mobile Mapping
o Integrates data from functional and structural surveys
o Integrated with Asset and Facility Management
PMS-SIT A GIS application
All the existing maps (orthophotos, CAD drawings, etc.) already available, and the data of previously
carried out surveys (roughness, friction, bearing capacity, etc.) are inserted in the same topographical-
geodetic reference system. All of them are integrated with the results coming from the new surveys,suitably represented.
PMS-SIT Integration of historical and new survey data
The distresses have been first classified in a catalog according to the ASTM D6433/2003 specifications . The defects are geo-referenced by type.For each defect the system provides size and severity.
PMS-SIT Inventory of the defects surveyed with LRIS/LCMS
As first step, it’s necessary to insert all General Data
PMS-SIT Geometry, Pavement Data and others
PMS-SIT Inventory of the defects surveyed with LRIS/LCMS
In the case of surveys carried out with Mobile Mapping Systems, the application manages the point cloud and provides some automatic feature extraction (e.g. the severity for rutting or the depth of alligator cracking).
The difference in altitude of the points of each cross section, is represented with a color ramp that enhances the deviations with respect to an average plane previously defined (3/4m).
PMS-SIT Point Clouds
A decay curve is defined for each material and each functional or structural status index.
The curve is automatically updated both inthe simulation phase and as a result of theeffective implementation of Maintenanceactivities.
PMS-SIT Decay Curves
In agreement with the Airport Postholder,
various catalogs of Maintenance
Activities can be defined.
Each catalog allows the organization of
the activities by type:
• Functional (maintenance)
• Structural (rehabilitation)
• Stopgap
PMS-SIT Definition of the Maintenance Activity Catalog
Unit cost and effectiveness are defined for each intervention, in terms of benefits compared to the performance curves for each index.
In the case of the PCI index, for instance, the system provides the list of defects that a specific activity can repair and any residual defect after processing.
Localized repairs usually lower the severity degree without completely eliminate the defect, or transform into other defects such as patching.
PMS-SIT Definition of the Maintenance Activity Catalog
After the intervention assignment to the Sample Areas or Section, the application performs the metric calculation of the necessary repair quantity, and estimates the total cost based on unit costs.
The calculation of the repair cost may also include any extra costs (ex. sign remaking)
PMS-SIT Calculation of the Maintenance Activity Costs
The application provides technical data on the effectiveness of the activity carried out, in terms of type and number of solved defects.
PMS-SIT Decision Support Tool
The application performs simulations on the effectiveness , distinguishing between functional activities (PCI value recalculation), and structural activities (residual life recalculation).
PMS-SIT Manual assignment of the activity and simulations
PMS-SIT is also used to define timing, process states, operators involved in the activities.
Thanks to the features provided by ArcGIS, it is possible to represent and immediately view the activities that have been planned, completed or under execution. It is also possible to view the activities on the costs or the execution technology.
The software also allows the management of ordinary activities: daily activities or inspections are stored in the database in order to have a historical view.
Finally, the system includes facility management functions.
PMS-SIT Support Tool for the Activity Management
Starting from the definition of the index that determines the priority, usually the PCI value, PMS-SIT provides the list of areas already represented in a graph, according to color ramps.
By activating the calculation of the Homogeneous Section, PMS-SIT provides the min. area of intervention
PMS-SIT Definition of the Activity Priorities
1. For the selection of the activity scenarios the following optimization techniques and criteria have been adopted:
• Network status (illimited budget)• Budget minimization • Maximization of the benefit/cost ratio
2. Selection of the area (set of branches or sections) that will be analyzed
