How it works

A two-stage process, each auditable by nature

Comtacti's road inventory was designed for high contractual-demand environments — concessionaires with ANTT and ARTESP obligations, lenders such as BNDES and IFC, and public agencies with competitive tendering processes. Traceability is not an additional report: it is how the system works.

1 Field

Detailed Visual Survey (DVS)

360° georeferenced video capture of the entire highway extent. The raw material for inventory — carried out by Comtacti or supplied by the client.

2 Office

Road Asset Registration

Classification and coding of all road elements from the 360° video, using the proprietary OMNI7 system. Each record linked to the source frame and coordinate.

Flexible contracting. Clients who already have their own georeferenced 360° or photographic survey can contract only the Asset Registration with OMNI7. Likewise, Comtacti can carry out only the DVS for clients who prefer to handle the classification in-house.

1 Detailed Visual Survey

The most complete possible capture
of the road in a single survey

The DVS is the field stage: Comtacti's vehicle travels the full extent of the road filming in georeferenced 360° video, in both directions. The result is the raw material for asset registration, for iRAP road safety analyses and for any study requiring detailed road visibility.

Equipment and methodology

Ladybug 30 MP camera

8,000 × 4,000 pixel resolution in 360° video. Captures the full lateral and vertical extent of the road — signage, assets, geometry and surroundings — in a single pass.

GPS PPP with < 2.5 m precision

Precision positioning system with embedded inertial unit to ensure continuity in tunnels up to 12 km without loss of georeferencing.

Real-time monitoring via OMNI7

Field routes are monitored in real time through the OMNI7 platform, enabling coverage gaps to be identified and rework triggered before the team leaves the area.

Filming in both directions

Increasing and decreasing directions covered in separate passes, ensuring full visibility of signage and assets on both sides of the road.

2 Road Asset Registration

Every asset classified, positioned
and linked to its source frame

From the 360° video captured in Stage 1 — or supplied by the client — Comtacti's team classifies and codes all road elements directly in the OMNI7 platform. GPS is automatic: there is no manual coordinate entry. Each record is linked to the exact frame from which it was extracted.

What the client receives

Asset Registration deliverables

Shapefile for GIS — georeferenced data ready for use in ArcGIS, QGIS and similar
CSV for Excel — complete asset table with coordinates, classification and attributes
VIDA CSV (iRAP) — export compatible with the road safety assessment platform
Segment reports — asset summaries by segment, type and direction
Full audit log — who classified, which frame, date and time of every record

How it works in practice

Specialisation by attribute

Each technician codes up to 3 specialised attributes simultaneously — not all 78 at once. Specialisation reduces errors and increases classification speed.

Automatic GPS by frame

When an element is classified in the video, OMNI7 automatically links the GPS coordinate from the corresponding frame — no manual coordinate entry, no positioning error.

Real-time supervision

The supervisor monitors coding as it happens, correcting inconsistencies before they accumulate. Audit is not a final stage — it is a continuous process.

Automatic geometry calculation

Curvature and gradients are calculated automatically by the system from the GPS track — eliminating human variability in geometric attributes.

Comtacti's differentiator

The system was built with auditability in mind

In a market where clients are regulated by ANTT, ARTESP and multilateral lenders, auditable data is not a differentiator — it is a contractual requirement. Comtacti brings this characteristic natively in the software, not as a manual review process.

Traceable source frame

Every inventory record is linked to the exact frame of the 360° video from which it was extracted. If the client contests any data, Comtacti presents the frame that proves the classification.

Per-operator log

The system automatically records who classified each element, in which frame and at which time. The log is immutable and delivered to the client as part of the audit report.

Independent recount

The client can request reclassification or independent recount of any segment at any time, at no additional cost for discrepancies identified in a contractual audit.

Inventory extension

iRAP - Road Safety Assessment

iRAP (International Road Assessment Programme) is the global method for assessing the risk of death and serious injury on roads. The methodology codes dozens of attributes per segment and generates a Star Rating that enables comparison and prioritisation of safety interventions — required by BNDES and IFC in road concession projects.

Active accreditation

Comtacti iRAP

Accredited organisation since 2018

OMNI7 system accredited for road surveys and road attribute coding. Active accreditation, renewed in 2022.

3 individually certified technicians

Senior members with individual Road Attribute Coding certification — ensuring operational redundancy on projects of any scale.

Native VIDA export

OMNI7 generates the VIDA CSV format directly from the registration — no rework. One field pass, two deliverables.

Who contracts

Multilateral lenders

BNDES and IFC require iRAP assessment in concession and highway financing processes with road safety impact.

Concessionaires and managers

Contracts with Star Rating improvement clauses — ARTESP, ANTT and DERs require initial and periodic assessment throughout the concession.

Engineering consulting firms

Road safety consultancies that need to subcontract iRAP coding to an accredited organisation.
