The U.S. Office of Surface Mining (OSM) Proposed Strength-Durability Classification System
Federal regulations for the surface mining of coal stress proper design and construction of stable waste rock disposal areas. A key to the long-term stability of these excess spoil fills...

Anatomy of Asphalt
Two main factors will combine over the next several years to alter the composition of asphalt pavements, which make up more than 90% of the paved roads in the U.S. First, a major research...
Out of the Lab...and into the Field?
Materials experts know very little about concrete's basic structure. Now, though, engineers at a research center sponsored by the National Science Foundation are working on...
Every Penny's Worth
Value engineering has been used in the construction industry since the 1960s, but highway projects have sometimes been thought of as too simple for VE studies. Now, with the increasing...
Caring for a Covered Bridge
Today the quaint Cornish-Windsor covered bridge (winner of this year's Outstanding Civil Engineering Merit Award) doesn't look much different than it did when...
Response of Ductile Iron Pipelines at Parkfield, CA to Loma Prieta Earthquake
A field experiment designed to investigate the performance of buried pipelines at a fault crossing has been constructed at Owens' Pasture near Parkfield, CA. The site was...
Evaluation of Automatic Earthquake Shutoff Valve Performance and Recommendations for Future U.S. Standards
Increasing interest of local and state government has developed in recent years regarding legislation requiring automatic shutoff valves for natural gas lines as well as lines containing...
Stochastic Responses of Lifeline Systems Under Seismic Excitations
A wave superposition model is proposed to predict the field motion on the basis of the seismic records obtained from a strong motion array. By assuming the ground motion to be a homogeneous...
Performance of Unreinforced Masonry Buildings During the Newcastle Earthquake, Australia
On December 28, 1989, an earthquake of Richter magnitude 5.6 shook the city of Newcastle. Newcastle is situated on the east coast of Australia only 100km north of Sydney. Eleven deaths...
Inductive Loop Detection/Testing with DSP Techniques
Vehicle traffic control is recognized as an effective way to relieve mounting traffic congestion in large urban areas across the country. The most common method of vehicle detection is...
Analysis of Automatic Vehicle Identification Technology and Its Potential Application of Florida's Turnpike
The Florida Department of Transportation contracted with the Center for Urban Transportation Research (CUTR) at the University of South Florida to conduct an analysis of automatic vehicle...
Perception and Control for Automated Pavement Crack Sealing
Pavement maintenance is a major transportation engineering activity that has seen only partial mechanization and virtually no automation. Crack sealing is a typical maintenance task in...
Highway Pavement Surfaces Reconstruction by Moire Interferometry
The necessary basis for any cost-effective highway and bridge deck pavement management program is reliable, complete and up-to-date information concerning the state of pavement surface....
Testing and Feasibility of VIPS for Traffic Detection
The California Department of Transportation (Caltrans) has asked the California Polytechnic State University (Cal Poly) at San Luis Obispo to investigate the effectiveness of existing...
Incident Detection Through Video Image Processing
A machine vision system for vehicle detection and traffic parameter extraction (called AUTOSCOPE) was recently developed at the University of Minnesota. Its advantages lie in its multispot...
Traffic Queue Detection Using Image-Processing
A method of queue/congestion detection is described using low cost image processing and computing hardware. It is capable of processing data from a length of roadway within a few seconds,...
Report of the DEVLONICS Video Based Traffic Detector Systems (DRS-CCATS/DTMSA)
In traffic monitoring systems many detectors are in widespread use to provide the necessary information. Image and video processing is one of the most defiant newcoming technologies in...
Stereo Vision with Scan-Line Cameras for Intrusion Detection on L.R.T. Tracks
In this paper we present a new method for the detection of intrusions by means of stereo vision in order to infer 3D information from two linear sensors. This method can be used for security...
Using Real-Time Location Information for Hazardous Materials Shipments
Real-time location information on shipments of hazardous materials can be used to update routing decisions while the shipments are in transit. The effects of unforeseen delays, accidents...
