Road safety evaluation through automatic extraction of road horizontal alignments from Mobile LiDAR System and inductive reasoning based on a decision tree

Abstract: Safe roads are a necessity for any society because of the high social costs of traffic accidents. This challenge is addressed by a novel methodology that allows us to evaluate road safety from Mobile LiDAR System data, taking advantage of the road alignment due to its influence on the accident rate. Automation is obtained through an inductive reasoning process based on a decision tree that provides a potential risk assessment. To achieve this, a 3D point cloud is classified by an iterative and incremental algo… Show more

“…In terms of road geometry safety, some scholars analyzed the force characteristics of cars under different road geometry conditions and established the mathematical models of car sideslip and rollover. Some scholars analyzed the force characteristics of cars under different road geometry conditions, established the mathematical models of car sideslip and rollover, and analyzed the impact of alignment on traffic safety [ 12 17 ]. Scholars have summarized the history of curve linear design in the United States from the two aspects (e.g., flat and vertical curves), especially the setting of easement curves [ 18 , 19 ].…”

“…More specifically, the road surface is extracted with best-fit plane detection algorithms based on robust methods (e.g., RANSAC) or using Principal Component Analysis (PCA) [37]. Road shoulders [38], sidewalks, or road alignment [39] can be extracted using decision trees [40] or fusion of feature-based and deep learning approaches [41]. Another important topic is road marking extraction.…”
