Bridge Damage Review?Loma Prieta Earthquake
The Loma Prieta Earthquake that struck the San Francisco Bay Area on October 17, 1989 caused varying degrees of damage on highway bridges. Within a few hours of the event CALTRANS had...
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...
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...
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...
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....
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...
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....
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...
Cars: A Demand-Responsive Traffic Control System
This paper presents a demand responsive traffic control system for networks based on improvements from a combination of OPAC and ACTS approaches. The system has shown clear advantages...
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...
Evaluation of Reliability of Road Network for Better Performance, Advanced Management and Future Network Design
