Manasan Ice Control Structure Rehabilitation & Bypass Designs
Ice control works built on the Burntwood River at Manasan Falls were damaged during the 1985 spring break-up. The ice boom had broken and the lowered pond level indicated that the rockfill...

Introduction, and Analysis of Survey—Preliminary Report of Task Committee on Recommendations for Standards in Hydraulics
To help formulate its recommendations for future standardization of tasks in hydraulic engineering, the Task Committee conducted a survey of practicing engineers. This survey indicated...

Proposed Methodology to Update Embayment Sedimentation Data for TVA Reservoirs
The purpose of this paper is to evaluate the accuracy and usefulness of bathymetric data resulting from routine fisheries and aquatic biology hydroacoustic surveys in TVA reservoirs for...

Determining the Optimum Level of Quality Management Effort
Quality management is an essential factor in construction project success. Determining the appropriate level of quality management effort remains a challenging managerial decision. A discussion...

3-D Positioning for Construction Surveying and Automation
Three-dimensional real-time positioning is a critical requirement to allow for improved surveying and autonomous vehicle control. Given such a system and a project data link, multiple...

The Soil-Rock Boundary: What is it and Where is it?
A major issue in many areas of Civil Engineering practice is the boundary between earth materials that are defined as soil and those that are defined as rock. Designers, contractors, and...

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...

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,...

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...

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...

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...

An Application of Advanced Technologies for Freeway Traffic Management—An Indiana Case Study
The Indiana Department of Transportation is in the process of implementing an electronic surveillance and control system on the Borman Expressway (I80/94). This paper presents a summary...

Stereo Vision Onboard a Vehicle for Obstacle Detection
We show how two linear cameras, mounted behind the windscreen of a car, can be used to detect the obstacles on the road in real time, even with small computer architectures. Results of...

Automatic Object Identification in Road
The methodology for automatic object recognition in real road traffic environment is presented. The proposed data acquisition methods have been tested on site. In addition, the fundamental...

Stereo Vision with Scan-Line Cameras for Intrusion Detection on L.R.T. Tracks
In this paper we present a new method for the detection of intrusions by means of stereo vision in order to infer 3D information from two linear sensors. This method can be used for security...

Design and Evaluation of Multi-Band Progression Schemes
Multiband is a new arterial progression scheme that has the capability to assign each directional road section with an individually volume-weighted band. The method offers to the traffic...

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....
