A Catastrophe Theory Approach to Freeway Incident Detection
This paper discusses an approach to incident detection on freeways that classifies traffic conditions at a single station rather than by comparing conditions at adjacent stations. The...

A Low Pass Filter for Incident Detection
A new algorithm for automatic incident detection was developed after observing that existing algorithm performance can improve if detector data are filtered before use. The new algorithm...

Automatic Incident Detection Using Image Processing Techniques: A Specific System Used in INVAID
INRETS together with other partners, within the European DRIVE program framework is working on developing a system able to detect incidents on motorway by processing video images (Jref....

A Distributed Real Time Knowledge-Based System Using Video Image Processing for Junctions Automatic Incident Detection
The scope of the INVAID project (in the European DRIVE program) is to build an automatic incident detection system which incorporate the image processing capabilities. In the urban aspects...

Minnesota Department of Transportation Experience in the Application of Advanced Traffic Management Systems
The Minnesota Department of Transportation (Mn/DOT) began deploying Advanced Traffic Management Systems (ATMS) in the early 70's. The Interstate 35W just south of the Minneapolis...

Identify the Marina User Market and Make the Customer a Part of the Planning Team: Designing and Managing for the User's Needs
A practical surveying method is described which allows a marketing firm to simultaneously - and quantitatively - analyze demographic market composition (for both upland and in-water uses)...

Burns Waterways?Boat Capacity Study
The results of a boat capacity study for the Burns Waterway located in the city of Portage, Indiana, close to the southern tip of Lake Michigan are presented. More than 650 recreational...

California Department of Transportation Seismic Retrofit Program: The Prioritization and Screening Process
Following the October 17, 1989 Loma Prieta Earthquake, the California Department of Transportation was designated as the lead agency to seismically retrofit all 23000+ public owned bridges...

Viscoelastomeric Connections in Seismic Structures
Nonlinear Kelvin and Maxwell impedances connect lumped masses to form arbitrary networks. Viscoelastomer-steel composite moment connections are modeled similarly, using auxiliary masses,...

Performance of Liquid Storage Tanks during the 1989 Loma Prieta Earthquake
Utilities and industrial facilities in the strong shaking area of the 1989 Loma Prieta earthquake include a large inventory of tanks of all types. The earthquake induced a few incidents...

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...

Results of the 1989 ASCE Airfield Pavement Survey
In November of 1989, the American Society of Civil Engineers Airfield Pavement Committee sent out questionnaires to airfield pavement engineers across the country to assess the most recent...

Guide to Post-Earthquake Investigation of Lifelines
This committee report, Guide to Post-Earthquake Investigation of Lifelines, will help the investigator become familiar with the overall operation...

Seismic Loss Estimates for a Hypothetical Water System
A Demonstration Project
This committee report, Seismic Loss Estimates for a Hypothetical Water System demonstrates how earthquake loss estimates can be developed for...

Right-of-Way Surveying
This manual, Right-of-Way Surveying Guide (Manual no. 75), is a revision and up-date of the Guide to Right of Way Survey Practices, published...

Pile Test for Earthquake Repair
Load testing for existing concrete piles was specified as part of a seismic retrofit at the Port of Oakland after the Loma Prieta event. The Port wished to use heavier cranes at cargo...

ASCE Salary Survey 1991
The 21st biennial ASCE salary survey of the engineering profession conducted by the ASCE Committee on Employment Conditions during the first half of 1991 is presented. It consists of an...

Freudenthal Lecture Developments in Structural Reliability
Rather than reviewing the details of developments in structural reliability theory and its implementation over the last few decades, more recent and more relevant reliability issues are...

Seismic Hazard Estimation in the Eastern U.S.
Probable seismic hazard is generally estimated considering five elements: 1) seismicity; 2) source radiation; 3) wave propagation (attenuation); 4) site response; and 5) ground failure....

Largest and Characteristic Earthquakes in the U.S. East of the Rocky Mountains
A new statistical procedure is proposed for the estimation of maximum earthquake magnitude M in intraplate regions. Starting from a historical catalog of events and a seismotectonic classification...
