Inelastic Behaviors of Pipelines Buried Through Liquefiable Zone
For the case of a major pipeline transmission system buried through in soil deposits that may be susceptible to liquefaction, its seismio environments can be considered in the following...

Seismic Hazards for Memphis Water Delivery Systems
Estimation of seismic hazards is the first essential task in performing the seismic risk assessment of a municipal water delivery system. This paper presents the evaluation of seismic...

Seismic Vulnerability of Memphis Water System Components
The vulnerability of selected components of the Memphis Water System is evaluated herein for a 7.5 moment magnitude earthquake within the southern portion of the New Madrid Seismic Zone....

Liquefaction Hazard Evaluation: Methodology and Application
Deterministic liquefaction potential evaluations are commonly done in engineering practice and several probabilistic models exist. In this paper an extended method is described that combines...

Liquefaction Hazard Analysis for Design of the Kern River Pipeline at the Muddy River Crossing, Southern Nevada
The 91.4-cm (36-in.) diameter Kern River natural gas transmission pipeline will cross the Muddy River in Moapa Valley, about 5 km west of Glendale, Nevada, in an area of relatively low...

Seismic Hazard Analysis of Buried Pipeline for Design
This paper concerns mainly the following three items on seismic hazard analysis of buried pipeline for design: (1) effects of pipeline length on risk, (2) effects of local site conditions...

An Expert System for Diagnosis of Earthquake Proof for Underground Lifelines
This paper reports a fuzzy expert system for the diagnosis of earthquake proof of gas pipelines with the aid of OPS83 tool. The fuzzy theory was employed to estimate seismic risk on the...

Seismic Behavior and Vulnerability of Pipelines
In this paper criteria and related features are described pertaining to the seismic design of pipelines and pipeline systems. The presentation begins by describing the past performance...

A Methodology for Assessing the Risk of Hazardous Materials Release Following Earthquakes?A Demonstration Study for the Los Angeles Area
A methodology for estimating the risk of post-earthquake hazardous materials releases was developed for the National Science Foundation and the National Center for Earthquake Engineering...

Simplified Numerical Analysis on Earthquake Response of Irregularly Bounded Surface Layer
Evaluation of seismic response of a soft surface layer is the essence in a design of a lifeline in this layer. For this purpose, a quasi-three dimensional ground model was developed by...

Application of Lateral Spread Hazard Definition Using Liquefaction Susceptibility Index to the Design of Buried Pipelines
Recent liquefaction hazard studies have made use of relationships developed to provide direct estimates of liquefaction displacements interms of liquefaction susceptibility index (LSI)....

Gas System Repair Patterns in San Francisco Resulting from the 1989 Loma Prieta Earthquake
Leak repair calls in San Francisco were tracked immediately following the 1989 Loma Prieta earthquake. This information was subsequently obtained from PG&E and examined for possible...

Measuring Section-Related Traffic Data by Correlation Methods?A New Approach to Traffic Monitoring and Control
Traffic monitoring and control systems require reliable realtime data on traffic flow for an efficient performance. A new 'class' of data, the so-called section-related data such as journey...

Continuum Modelling of Traffic Dymamics
Two new efficient higher-order continuum models are proposed to improve modelling of traffic dynamics. The new models do not require the use of an equilibrium speed-density relationship,...

Operation of Freeway Simulation Tools on I-35W
The paper discusses the experience of the staff of the Minnesota Department of Transportation in experimenting the traffic simulation models: FREQ10 and KRONOS6.2 . The project development...

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...

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...

An Application of Advanced Technologies for Freeway Traffic Management?An Indiana Case Study
The Indiana Department of Transportation is in the process of implementing an electronic surveillance and control system on the Borman Expressway (I80/94). This paper presents a summary...

Stereo Vision Onboard a Vehicle for Obstacle Detection
We show how two linear cameras, mounted behind the windscreen of a car, can be used to detect the obstacles on the road in real time, even with small computer architectures. Results of...
