Crash reduction following installation of centerline rumble strips on rural two-lane roads [PDF]

open access: yesAccident Analysis & Prevention, 2004
Rural two-lane roads generally lack physical measures such as wide medians or barriers to separate opposing traffic flows. As a result, a major crash problem on these roads involves vehicles crossing the centerline and either sideswiping or striking the front ends of opposing vehicles. These types of opposing-direction crashes account for about 20% all

Knowledge-Based Detection and Assessment of Damaged Roads Using Post-Disaster High-Resolution Remote Sensing Image

open access: yesRemote Sensing, 2015
Road damage detection and assessment from high-resolution remote sensing image is critical for natural disaster investigation and disaster relief. In a disaster context, the pairing of pre-disaster and post-disaster road data for change detection and ...

Trajectory Planning of Automated Vehicles in Tube-like Road Segments

open access: yes, 2017
This paper presents a method based on linear programming for trajectory planning of automated vehicles, combining obstacle avoidance, time scheduling for the reaching of waypoints and time-optimal traversal of tube-like road segments.

CLiNet: Joint Detection of Road Network Centerlines in 2D and 3D

open access: yes, 2023
This work introduces a new approach for joint detection of centerlines based on image data by localizing the features jointly in 2D and 3D. In contrast to existing work that focuses on detection of visual cues, we explore feature extraction methods that are directly amenable to the urban driving task. To develop and evaluate our approach, a large urban

Effect of anisotropy and destructuration on behavior of Haarajoki test embankment [PDF]

open access: yes, 2009
This paper investigates the influence of anisotropy and destructuration on the behavior of Haarajoki test embankment, which was built by the Finnish National Road Administration as a noise barrier in 1997 on a soft clay deposit. Half of the embankment is

Forest Roads Mapped Using LiDAR in Steep Forested Terrain

open access: yesRemote Sensing, 2010
LiDAR-derived digital elevation models can reveal road networks located beneath dense forest canopy. This study tests the accuracy of forest road characteristics mapped using LiDAR in the Santa Cruz Mountains, CA. The position, gradient, and total length

Evaluation on the Horizontal Alignment of Road Centerline using GIS Programming

open access: yesJournal of the Korean Society of Road Engineers, 2012
The horizontal alignment of road is deeply related with the stability of the road and traffic capacity. It is necessary to analyze horizontal alignment of road accurately for efficient maintenance of the road and relevance judgment about the standard.
