YonaPMS.DataIntegrator utilizes camera arrays and additional components to collect updated information regarding road conditions. These components are connected to a PC network inside the survey vehicle that enables data storage and real-time location information. Camera operators view high-resolution videos of road conditions and features, and can make on-the-fly adjustments as required.
YonaPMS supports 3 or more front digital color video cameras that deliver a panoramic view of the roadway while the vehicle travels at up to 100 km/h under normal driving conditions. These cameras capture video of assets such as guardrails, slopes, posts, lights, signs, signals, gas stations, and bus stops. Two rear video cameras are supported, with pictures stitched together to create a mosaic up to 100m, by lane width of up to 4.10m. Measurements include linear and aerial features. Side video cameras can be added to capture telephone poles, street lights, and retaining walls, etc. Data is presented in tables and GIS-referenced maps.
The YonaPMS.Viewer enables the viewing of captured video, and positioning of user-selected points in a geo-referenced coordinate system within a GIS environment. A Video Recording System controls the data collection. A DMI (Distance Measurement Instrument) triggers the cameras as the vehicle travels at a pre-determined speed, and enables the geo-referencing of the data. A Sub-Metric GPS (Global Positioning System) enables the creation of a GIS-referenced map that can be layered with various infrastructure data. An Inertial Motion Sensor (IMS), positioned at the center of the vehicle, contains gyroscopes that determine the vertical and horizontal slopes and the curve radii of the roadway. A Laser Rutting Measurement Tool digitizes the shape of the pavement cross section for rutting evaluation. A Laser Roughness Profiler captures real-time roughness data for International Roughness Index (IRI) determination.
