Highway Cross-Slope Measurement using Mobile LiDAR

Abstract: Ensuring adequate pavement cross-slope on highways can improve driver safety by reducing the potential for ponding to occur or vehicles to hydroplane. Mobile laser scanning (MLS) systems provide a rapid, continuous, and cost-effective means of collecting accurate 3D coordinate data along a corridor in the form of a point cloud. This study provides an evaluation of MLS systems in terms of the accuracy and precision of collected cross-slope data and documentation of procedures needed to calibrate, collect, and p… Show more

“…The sensor is scanning the building, landscapes, and other features at highway speed while recording positional data using a Global Positioning System (GPS), Inertial Measurement Unit (IMU), a Distance Measurement Instrument (DMI), and digital cameras simultaneously. The resulted point cloud contains highly accurate 3D locations of highway assets and nearby areas (Shams et al, 2018). However, automated extraction of useful information from the large volume of the ponts within a point cloud has been a challenging topic in Photogrammetry and Computer Vision.…”

“…There are a number of considerations when choosing a method for utility pole mapping including accuracy, safety, cost, and time. (Baffour, 2002;Shams et al, 2018;Souleyrette et al, 2003). High resolution aerial images can be accurate data sources, but manual extraction of pole locations is time consuming and conventional ground control surveying is needed to achieve high accuracy (Wen et al, 2019).…”

“…Further, weather conditions can affect accuracy (Holopainen et al, 2013). Conventional surveying is especially tedious for large areas and poses safety risks to personnel due to their proximity to traffic (Shams et al, 2018;Souleyrette et al, 2003).…”
