Enhanced Data Visualization for Point Data Using Software You Already Have
Between 2001 and 2014 there were over 1.7 million traffic crashes in Arizona. Due to the volume of crash point data 2D display often does not clearly convey the number or density of the crash locations. When developing a process for sliding window analysis, a method for analyzing road segments that provides a snapshot of crash distribution for equal windows of road, an opportunity for displaying crash frequency in 3D became apparent. The presentation will demonstrate the use of ArcMap, ArcScene and Google Earth to create and display 3D Crash Frequency Models. This method could be easily adopted across multiple disciplines to enhance data visualization.
