Development and evaluation of traffic prediction systems
(Virginia Tech, 1994-04-12)
<p>Developing real-time traffic diversion strategies is a major issue of Advanced Traffic Management Systems (ATMS), a component of Intelligent Vehicle Highway Systems (IVHS). Traffic diversion utilizes available capacity ...
Stability of Levees and Floodwalls Supported by Deep-Mixed Shear Walls: Five Case Studies in the New Orleans Area
(Virginia Tech, 2011-09-08)
Increasing interest, from the U.S. Army Corps of Engineers (USACE) and other agencies, in using deep-mixing methods (DMM) to improve the stability of levees constructed on soft ground is driven by the need to reduce levee ...
Stereological Interpretation of Rock Fracture Traces on Borehole Walls and Other Cylindrical Surfaces
(Virginia Tech, 2005-09-16)
Fracture systems or networks always control the stability, deformability, fluid and gas storage capacity and permeability, and other mechanical and hydraulic behavior of rock masses. The characterization of fracture systems ...
Some aspects of stratified flow in closed conduits
(Virginia Polytechnic Institute, 1966)
Methodology for evaluating transportation-induced regional development
(Virginia Tech, 1996-06-05)
<p>There has long been a recognition that efficient transport plays a key role in supporting a dynamic economy and a high quality of life. However, traffic increases along with population and income, and traffic congestion ...
System Redundancy Evaluation for Steel Truss Bridge
(Virginia Tech, 2015-10-19)
In current bridge practice, all tension members in a truss bridge are identified as fracture critical members which implies that a collapse is expected to occur once a member of this type fails. However, there are several ...
Development of a Comprehensive Framework for the Efficiency Measurement of Road Maintenance Strategies using Data Envelopment Analysis
(Virginia Tech, 2007-09-19)
For the last two decades, the road maintenance concept has been gaining tremendous attention. This has brought about new institutional changes, predominant of which is the challenge for maintenance managers to achieve ...
Micromechanical Aspects of Aging in Granular Soils
(Virginia Tech, 2012-09-03)
Granular soils exhibit a generally beneficial change in engineering properties with time after deposition or densification, during a process commonly known as aging. Soil properties reported to change during aging include ...
An Empirical Method of Ascertaining the Null Points from a Dedicated Short-Range Communication (DSRC) Roadside Unit (RSU) at a Highway On/Off-Ramp
(Virginia Tech, 2018-09-26)
The deployment of dedicated short-range communications (DSRC) roadside units (RSUs) allows a connected or automated vehicle to acquire information from the surrounding environment using vehicle-to-infrastructure (V2I) ...
Sorption of Boron and Chromium Onto Solids of Environmental Significance: Implications for Sampling and Removal in Water Treatment
(Virginia Tech, 2005-09-06)
The chemistry, analysis, treatment, and occurrence of boron and chromium are of high interest since they are under consideration for revised MCLs in potable water. As a starting point to guide regulatory decision-making, ...
