ROMDAS with LCMS Complete High Speed

Data Collection System

ROMDAS System Overview

• Supplying data collection system for over 25 years

• Over 200 systems in 60 countries

• Modular design offering flexibility and wide variety of data

• Proven in wide variety of conditions

Systems - Tailored Design

• ROMDAS System

• Bump Integrator (Roughness – unpaved roads)

• High Res DMI (Distance/Chainage)

• GPS Receiver (capable of sub-meter DGPS)

• LCMS with Roughness + Geometry upgrades

• Multiple ROW cameras

• Computer system, power supplies and all other required accessories

TNRSP – Similar Systems• Tamil Nadu Research Sector Project (TNRSP),

have been using 2 almost identical systems since 2011

• Successfully surveyed around 60,000km or roads to date

• Contract is about to be extended for another year

ROMDAS LCMS collects• Automatic crack and defect detection and analysis

including; cracking (width, length, depth), potholes and raveling/joint data, sealed crack detection.

• Pavement Images• Transverse Profiles

Rut Depth, Width & Cross-Sectional Area for each wheelpath,

• Macro-Texture (MPD) in 5 bands across the whole lane width,

• Optional Upgrade:– Roughness (IRI)– Geometry– FOD Detection (Airports)

Cracking & Defects

• Survey Speed 0 – 100km/h.• Conforms to IP-65 (NEMA 4).• Operates at 5,600 Hz (Profiles per second).• 4 m profile width.• Laser imagery allows for data collection in day or night

conditions.• Outputs generic MS Access (.mdb) files for raw data, as well as

JPEG images which show the quantity and severity of defects at 10m intervals.

ROMDAS LCMS Features

• Scanning Laser; accurately measures the transverse profile across the full lane width.

• Macro-texture Measurement; can be measured over whole pavement.

• Lane tracking; eliminates data variability and inaccuracies due to vehicle wander ‘year-on-year’.

• Roof Mounted Equipment; mounted 2.2 m above pavement surface, at rear of vehicle.

• Roughness Inertial Measuring Unit (IMU); instead of traditional accelerometers.

• Validation tool; unique tool which validates the calibration.

• Laser based pavement imaging; automated defect detection, lane marking detection, high quality pavement images (with optional defect overlay).

Special Features

Benefits of using the LCMS

Very high accuracy data making it perfect for analysis of major highways,

High operating speed (up to 100km/h),

Wide variety of data collected, Identification of lane markings mean the unit can automatically adjust

the position of data (like MPD bands and Roughness) to match user-defined locations. In turn giving increased accuracy (i.e. removes the influence of the driver on the collection of data),

Raw data profiles are recorded allowing for re-processing using different parameters.

Real time status provided to operators

Operation PrincipleData Collection:

High accuracy pavement profiles

Real-Time Status Display

Real-time status display. Givingoperators immediate feedback on correct operation of system.

Post-ProcessingPavement Analysis

Outputs a wide variety of pavement analysis data used in deterioration modeling and maintenance planning

The LCMS Measures Every mm Of The Roads Surface

Excellent 3D accuracy (0.5mm),

Good lateral resolution (1mm),

High acquisition rate (5,600 profiles/s),

What Makes 3D Sensors Perfect For Crack Detection?

45 million 3D and 2D points/s

Lane Tracking•LANE MARKINGS are used to correct profiles and compensate for driver wander•Simplifies certification procedures•Eliminates the need to certify operators

Macro Texture Network survey is possible at 100kmh

Full lane width is measured

5 AASHTO bands

Great repeatability

Automatic lane marking detection

Transverse Profiles and Rutting Most accurate transverse profiler on the market with

4,000+ points per profile

Calculate Rut Depth, Rut Width and Cross Sectional

Area or wheel path depressions.

ROMDAS Data Acquisition & Processing Software

Microsoft Access (.mdb) files created contain a number of tables that reference all data to Chainage and/or GPS,

Access databases are easily exported to most asset management, GIS mapping and highway maintenance planning software,

DataView: Post – Processing Software

DataViewDataView is used to perform several advanced data processing steps. These include;

1. Process video images for asset and condition data,

2. Integrate multiple survey files into a single database,

3. Present data in customised charts,

4. QA Data by viewing all datasets link to Video, GIS Map and Charts Simultaneously

5. Create GIS maps with exportable layers
