In order to obtain the quantitative relationship between multisource data from road landscape and driving visual comfort in two-lane mountainous road, we collected driver's eye movement environment through real vehicle tests. The threshold segmentation method target area ratio are used process image, spatial enclosure degree is express sense of closure. addition, an HSV color model established ...

Introduction: Appropriate definition of the distance measure between diffusion tensors has a deep impact on Diffusion Tensor Image (DTI) segmentation results. The geodesic metric is the best distance measure since it yields high-quality segmentation results. However, the important problem with the geodesic metric is a high computational cost of the algorithms based on it. The main goal of this ...

In order to solve the problem of highway standardization management ability description, evaluation and improvement, in this paper, a highway standardization management maturity evaluation model has firstly been put forward. Moreover, the influence highway qualitative factors of implementing the standardized management have analyzed and its evaluation index system has constructed. Furthermore, ...

A link layer controller is derived using a vehicle density conservation ow model. Control laws are considered for three highway topologies: a single lane highway, a highway with multiple discrete lanes and a highway with an arbitrary 2 dimensional ow pattern. The control laws obtained for each of the topologies is distributed and is very suited for implementation at lower levels of the AVHS con...

Rural highway is the foundation of highway network construction and the important bridge for balancing urban and rural harmonious development. Rural highway has the basic, pilot and driving function to new rural construction. This paper took a sampling survey on 173 villages in Hebei Province. According to the 687 questionnaires, this paper set up an evaluation system of the rural highway const...

Highway transportation crashes are the leading cause of fatal injuries in the United States for both workers and the general population (1,2). Prevention of work-related highway transportation deaths, and highway transportation deaths in general, are long-standing public health priorities (1,3). To assess trends and help guide the prevention of occupational highway transportation deaths, CDC an...

This paper presents an accurate and stable method for object defect detection visualization on building infrastructural facilities. uses drones cameras to collect three-dimensional (3D) point clouds via photogrammetry, orthographic or arbitrary views of the target objects generate feature images points’ spectral, elevation, normal features. U-Net is implemented in pixelwise segmentation using m...

Currently, radiometric thermography image has been explored adequately as alternative advance Non-Destructive Testing (NDT) especially for early detection analysis in various applications. Systematic calibration, higher spatial resolution and high degree order processing, imagery potential to be used concrete structure defect detection. Therefore, this study is carried out examine the on bridge...
