2 Overview ROMDAS… Is vehicle mounted equipment, Is modular, ROMDAS has been developed by Data Collection Ltd. (DCL) as a low cost modular system designed to collect road and pavement data using any vehicle.ROMDAS…Is vehicle mounted equipment,Is modular,Offers equipment for collecting a variety of data and a variety accuracy levels,Cost efficient equipment,Can be installed on most local vehicles
3 HistoryFirst developed in 1989 by Dr Chris Bennett in response to his work in India and other developing countries where data collection equipment was expensive and impractical.The first system was developed in New Zealand with assistance from members of the University of Auckland.During the early years the heart of ROMDAS’ success was due to the Bump Integrator which was popular in developing countries due to its low cost and robust design.As the years passed and pavement data collection requirements increased new modules (e.g. video, TPL, GPS) were developed and integrated into the central ROMDAS system.In 2003 DCL was purchased by two employees; Paul Hunter and Raj Mallela. Both owners have kept closely to the philosophies with which the company was founded.In the last 5 years, DCL has integrated a number of high-end technology modules (e.g. LRMS, Geometry and LCMS) and can now offer customers high accuracy solutions as well as more traditional low cost options.
4 DCLs Point Of Difference Our success within the Road Maintenance industry can be put down to three main reasons;Financial – ROMDAS equipment is positioned at the lower end of the cost spectrum in the vehicle mounted pavement analysis market, while at the same time offering data quality equal to competitors.Service – customer support is a high priority for DCL. We aim at ensuring our customers are trained and supported so that their equipment is functioning at optimal levels. This applies at not only time of purchase but also for post-sale support.Innovation - ROMDAS equipment is constantly being developed. While entry level systems have mostly standardised designs, more technical systems are customised by DCL’s production team to best suit the specific situations and needs of customers.With many data collection systems in the market offering very similar high-end modules, ROMDAS tries to differentiate itself by offering a variety of low-cost entrance level equipment which can then be upgraded in the future to higher specification modules as the road conditions improve.
5 The ROMDAS SystemThe ROMDAS system itself comprises of the central components and software licences that allow for data acquisition and analysis. It is the ROMDAS system that the variety of data collection modules and sensors connect to and is therefore a requirement for all new survey vehicles.Standard equipment included in the ROMDAS system:ROMDAS Data Collection Software,Proximity sensor DMI,Power distribution box and cable,Vehicle power supply for survey computerHardware interface,Other accessories and basic tools needs for installation and maintenance.
6 The ROMDAS SystemROMDAS and its modules can collect the following information;Location Referencing PointsLinear Profile/Roughness (IRI)Transverse Profile and Rut DepthsRight Of Way Road Video SurveyPavement Video SurveyRoad Condition RatingInventory & Asset SurveyGPS CentrelineRoad GeometryLaser SurveyingHigh Accuracy DistanceAutomated Crack Detection3D Pavement Surface ModellingPavement Texture (MPD & SMTD)
7 LCMS - Measures every mm of pavement across and along the road
8 ROMDAS System: LCMSThe ROMDAS Laser Crack Measurement System (LCMS) uses 2 high powered scanning lasers to measure a variety of pavement characteristics. E.g.:Automatic crack and defect detection and analysis (including; crack severity, potholes and ravelling),Rut Depth, Width & Cross-Sectional Area for each wheelpath,Macro-Texture (MPD) in 5 longitudinal bands,This system represents a trend in data collection technology towards multipurpose modules for collecting a wide variety of high accuracy data.
9 Optional Upgrades to LCMS Scanning Laser Roughness (IRI)Raveling/Joint DataGeometryFOD Detection (Airports)Recommended ROMDAS Modules for use with LCMSRight Of Way Video Logging (Asset Inventory)GPS (Location Referencing)DataView (Post Processing Software)
10 The LCMS has a variety of advantages and benefits that far exceed traditional multifunctional data collection devices. The high powered scanning lasers are capable of profiling every millimetre on the road surface and identifying a wide variety of pavement characteristics.
11 Special FeaturesThere are several unique features to this system which significantly enhance the data reliability and accuracy over other traditional multi-laser profilometers. These include:Scanning Laser; accurately measures the transverse profile across the full lane width.Macrotexture 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 quickly calibrates the equipment on a weekly basis.Laser based pavement imaging; automated defect detection, lane markings, high quality pavement images (with optional defect overlay).
12 Lane TrackingA key advantage to using the LCMS system is the ability for data sets to be referenced to the lane markings and kerb positions instead of the vehicle transverse position travelled which will vary from year to year. This unique feature can be used when calculating the wheelpath and lane roughness, Macrotexture Measurement and rutting scan width.
13 Macro TextureThe LCMS is unique in that with the very high transversal scan rate of the laser the Macro texture can be calculated for all parts of the complete pavement area. The LCMS reports the Mean Profile depth (MPD) macro texture and / or Road Porosity Index (RPI) in 5 adjustable width longitudinal bands across the whole lane width (the 5 AASHTO bands are: central band, two wheel path bands, and two outside bands).
14 ROMDAS System: LCMS Survey Speed 0 – 100km/h. IP-65 (NEMA 4). Operates at 5,600 Hz (Profiles per second).4 m profile width.Creates Access (.mdb) files for raw data, as well as JPEG images which show the quantity and severity of defects at 10m intervals.Laser imagery allows for data collection in day or night conditions.
15 ROMDAS System: LCMS Standard equipment included with the LCMS module; 2 x LCMS laser profiler units,Rack mount LCMS controller,All necessary cabling,All external mounting,Basic tools and accessories for installation and maintenance.
16 ROMDAS System: LCMS Benefits 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
