Recent Developments in Safety Research from the Gas Research Institute
Recent developments in Safety Research, as supported by the Gas Research Institute (GRI), have consisted primarily of hardware-oriented applications to various gas industry safety operations....
Identifying Transportation Control Measures: a Straighforward Approach to Identifying Transportation Control Measures to Address Concerns with Air Quality
The 1990 Clean Air Act Amendments (CAAA) exemplify society's increasing environmental concern. Regions not attaining the CAAA requirements must develop methods to reduce the pollution....
Trip Rates Adjustments for Impact Assessment and Congestion Management
Evidence that all urban trips are not equal and that trip rates need to be adjusted to reflect the differential contribution of trips to traffic loads and congestion is presented. Adjustments...
Influence of Lateral Wind on Driving on Offshore Bridge
The Honshu-Shikoku Bridges are a system of highways crossing over the sea, where cross-winds variously affect vehicle behaviour. This is the intermediate report on the surveys aimed at...
Traffic Accident Analysis System
While statistical data on traffic accidents are invaluable in devising effective traffic safety measures, the number of data items and samples are vast and they must be processed and edited...
Reinforced Concrete
Recent developments and procedures used to model reinforced concrete using finite element analysis are summarized. Special emphasis is placed on the results of a survey of papers published...
3-D Deformation Analysis of Pile Groups During Wave Loading
Deformation predictions of pile group supporting one leg of Magnus platform were conducted using the 3-D nonlinear computer program SPLICE (Structure/Pile/Soil Interaction Analysis) and...
Evaluation and Monitoring of Pile Performance Using Dynamic Measurements in Supporting Offshore Structures
The installation of offshore platforms into deeper waters and new environments is accompanied by an increasing uncertainty in the structure response, foundation design and performance....
A Centrifuge and Analytical Study to Evaluate Suction Caissons for TLP Applications in the Gulf of Mexico
This paper documents the results of a combined centrifuge and analytical study to evaluate the behavior of steel suction caissons under loading and soil conditions typical of deepwater...
Execution and Evaluation of High Capacity Caisson Load Tests in Glacial Deposits
As part of the Boston Harbor clean up project, the new 1,000 mgd Deer Island Sewerage treatment plant includes ten 240 feet high egg-shaped 'residuals' tanks. Contract documents called...
Hong Kong's Wastewater Underground
Standard Hong Kong methods for siting the new $18 million Stanley Wastewater Treatment Plant in Hong Kong Island's South District were running into trouble. The rocky coastal...
Case Study of an Offshore Horizontal Boring
A pipeline system was needed to transport natural gas from a discovery in Mobile Block 823 to Mobil's existing system inside Mobile Bay. Sand Island, a small barrier island off Dauphin...
Wave Forecasting for Construction in Mobile Bay
Wave heights were forecast for day-to-day pipeline construction operations in the Main Pass area of Mobile Bay. A low-cost forecasting procedure was developed using the wave generation...
Nonlinear Shoaling and Impact of Waves on Coastal Structures
A two-dimensional fully nonlinear potential flow model is used to calculate shoaling of solitary and enoidal waves over a sloping bottom and interaction with submerged or emerged coastal...
High-Resolution Interwell Seismic Experiments in Sedimentary Formations
High-frequency interwell seismic data were acquired to examine full waveforms recorded in the pulsed mode and in the swept mode as well as to perform traveltime inversion tomography for...
A Wax-Coupled Borehole Seismic Detector for High-Resolution Measurements
A triaxial borehole seismic detector was developed for high-resolution measurements at frequencies up to 2,000 Hz. Applications for this detector include three-component shallow reverse...
Traffic Data Collection: What Really Needs to be Done?
The collection of 'existing' traffic data such as the 24-hour counts, turning movement counts, driveway volumes, and vehicle classification counts near the proposed project site becomes...
A Guideline for Determining Minimum Threshold Requiring Traffic Impact Studies
Over the years, a number of localities have developed and adopted some form of traffic impact assessment (TIA) guidelines. As part of this study, an informal survey conducted showed that...
The Foundation for a Successful Traffic Impact Analysis
Both governmental agencies and private developers use the information developed in a traffic impact analysis (TIA).Traffic Impact Studies can be an important tool in efforts to maintain...
Analyzing Fast-Food Drive-Up Window Site Impacts
Peak-period queueing at a fast-food restaurant drive-up window was observed. The study found that queueing behavior equations based on random arrivals and service times overestimated the...
