Visualization of the Effect of Topography on Connected Vehicle Communications using LiDAR-derived Models and Interactive Mapping Techniques

Abstract

The topography surrounding a connected vehicle (CV), includingroadway feature obstructions,the built environment,and vegetation such as trees, can negatively affect GPS receiver performance and thus the algorithms used to provide CV system alerts. Therefore, it is important to understand the performance of CV systems with regard to the physical topography of the earth. Visualization of an area from the point of view of a car traveling along a roadway can be useful in communicating the role topography can play in the obstruction of CVcommunications. In this project, a combination of tools wasused to construct a LiDAR-derived raster image of a test area and derive the skyline for various points representing vehicles traveling on a roadway. Both 2-D and 3-D visualization techniques were used to develop interactive mapsas an end-product. These mapsallowedfor visual exploration of the topography of a region alongside the data quantifying the topographical environment and CV performance variables, for any point along a roadway. These visualizationproducts allow those involved in the development of CVtechnology to better understand the effectsthat topographical obstructions can have on these systems and assist them in refining these technologies toward eventual deployment (PDF) Visualization of the Effect of Topography on Connected Vehicle Communications using LiDAR-derived Models and Interactive Mapping Techniques.
