Elevated Water Tank Inelastic Seismic Analysis
In 1988, the Seattle Water Department hired CYGNA, a consulting firm, to assess the seismic reliability of their water system, since major earthquakes can occur in the area. Their study...
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...
Loss and Recovery of Critical Lifelines Following Recent Hurricanes
Hurricanes significantly affect the performance of critical lifelines. An overview of the loss and recovery of power supply, transportation, communication, and water/wastewater systems...
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 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...
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,...
Application of Fuzzy Set Theory to the Analysis of Transportation Problems
The potential of applying fuzzy set theory is discussed. Fuzziness in the nature of transportation engineering problems is identified and typical fuzzy theory techniques are presented....
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...
Heavy Traffic Control Measurement Techniques and Control Strategies
Advanced technologies for traffic detection for freeway control systems are described. mm-wave radar detectors are used with a correlation of vehicle reflexion patterns to acquire section...
Assessment of the Sate-of-the-Art of Robotics Applications in Highway Construction and Maintenance
Automation and robotization in highway construction and maintenance are currently under active development in the United States and other countries around the world. Although road construction...
Applications of Robotics and Automation in Highway Maintenance Operations
This paper deals with the applications of Advanced Automation and Robotics in highway maintenance operations. The basic components of Robotics and Automation technologies are studied and...
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....
Design Considerations for Automated Pavement Crack Sealing Machinery
The purpose of this paper is to discuss the numerous considerations for designing automated machinery for the sealing of cracks in pavement. Operational requirements are presented and...
Comparison of Traffic Signal Systems in Australia and North America
Dynamic coordinated traffic signal systems were developed in Australia in the 1970's, and are now installed in many countries. In contrast, strong interest in new generation...
Fully-Distributed Control of Signal Networks
A fully-distributed real-time control strategy is described for signalized networks. The signals make compatible, simultaneous decisions about cycle length, offset and splits, without...
