1. Travel way measurement system, comprising a platform with a position determining unit (PDU) mounted on a vehicle for indicating heading, pitch and roll of the vehicle, a computer mounted in the platform for recording heading, pitch and roll information from the PDU, distance measuring instruments (DMI) connected to the vehicle and to the computer for providing travel distance information to the computer, sensors mounted on the platform and connected to the computer for providing information of distances of the sensors above the surface of the travel way, a scanner mounted on the platform adapted for scanning around the vehicle transverse to a longitudinal axis of the vehicle on, over and adjacent to the surface of the travel way and connected to the computer for providing to the computer position range, angular position, and reflective signal strength information relative to the scanner and to the vehicle of objects along, over and away and adjacent to the travel way, whereby the computer determines and records precise locations of the platform along the travel way, precise positions of the platform in the travel way, and precise slopes and surface conditions of the travel way, and adapted for detecting edge of pavement, roadside profile, edge drop-off, shoulder, curbs, sidewalk, guardrails, roadside features, driveways, drainage facilities, pavement distress, vertical clearance, overhead features, surface roughness, and adapted for providing location referenced outputs of cross sections, visualizations, simulations, plan and elevation drawings, data for software, and 2D and 3D rendering.
