Estimation of Overwash Bore Velocities Using Video Techniques
Overwash data were collected at a site on the Isles Dernieres, LA barrier island chain during Hurricane Gilbert in September 1988. A video technique was applied that allowed the quantification...
Along the Road to K
Allegations of threats from toxic and hazardous wastes advanced on political and emotional planes threaten, themselves, to overshadow the facts that should dominate ultimate technical...
Probing the Golden Gate
The Golden Gate Bridge has just come through the most detailed analysis ever attempted in its 53-year-old history. This analysis was squeezed into a desktop computer that calculates twice...
Application of Personal Computers to Field Flow Measurement
Flow measurements are often necessary to verify the performance of hydro turbines for regulatory, contractual, or engineering purposes. Historically, several methods utilizing various...
Standardization of Culvert Flow Computations
Culvert flow computations are generally computed by the Federal Highway Administration's (FHWA) nemographs or its HY8 computer program, the U.S. Army Corps of Engineers'...
Liabilities in Temporary Structures Failures?Representative Case Histories
Eight case studies involving construction accidents caused by failure of temporary structures are presented. These studies illustrate the oftentimes unintended consequence of utilizing...
Temporary Traffic Deck Over Braced Excavation
A case history is used to examine the planning, design, and installation of a temporary traffic deck over a 23-foot-deep braced excavation. The deck was installed in a three-phase sequence...
Construction Accident Analysis: The Inductive Learning Approach
This paper presents the use of inductive learning in the analysis of construction accidents. It provides a brief description of ROUGH, an inductive system based on the theory of rough...
State and Local Issues in Transportation of Hazardous Waste Materials
Towards a National Strategy
This proceedings contains papers presented at the specialty conference State and Local Issues in Transportation of Hazardous Materials: Towards a National Strategy held on May 14-16, 1990...
Taller Tunnels
Between 1984 and 1991, Shannon & Wilson, Inc., Seattle, designed renovation programs for more than 25 mi of tunnels for four western railroads. We performed all of this work under...
Double-Decking the Freeways
Elevated highways cost more than at-grade construction. Nonetheless, the hidden costs of increased traffic congestion and the real cost of urban right-of-way make elevated highways feasible....
Seismic Practices for the Air Transportation System: Evolution and Needs
The seismic performance of air transportation systems is reviewed. The evolution of seismic design criteria and practices for major air transportation system elements is discussed. The...
Applications of Strain and Deflection Monitoring Systems for Post-Earthquake Safety and Usability of Lifelines
The paper proposes and discusses a variety of strain and deflection monitoring devices and systems for post-earthquake safety evaluation of lifelines. There is clearly a need, both in...
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...
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...
Automatic Vehicle Classification System
China has recently completed a number of freeways, all of which were financed in part by the Ministry of Communications and local governments and in part by loans from the World Bank,...
Analysis of Roadside Equipment and Central Facilities for Innovative Driver Information and Traffic Control Systems
Following a top down analysis of a selected set of innovative RTI functions, we identify in this paper the requirements and characteristics of the roadside equipment and central installations...
Traffic Reporter is a PC-based graphical, interactive, traveler information system being developed to meet the informational needs of Seattle-area commuters. The goal of Traffic Reporter...
SINOD?A Location Reference Tool for Road Information Systems
This paper focuses on the setting up of a location reference system - named SINOD - envisaged as a basic requirement for on going actions and for expected developments in the field of...
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,...
