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....
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...
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...
Two Approaches for Characterizing Images of Rail Surface Flaws
Rail surface flaws can be removed by grinding to improve the life of rail and provide a safe, smooth running surface. To avoid time consuming and costly visual inspection in the determination...
Automated Analysis of Pavement Distress Data
A system model that can be used for the analysis of pavement distress data collected by various visual devices (e.g. photographic film) is presented. The models operate at two levels:...
Pavement Image Processing Using Neural Networks
This paper discusses the potential for employing neural network models in the pavement image interpretation and classification stage of an automated pavement condition evaluation system....
Video Image Processing for Toll Operation Evaluation
Toll motorway companies are very much concerned with toll plaza operation and its appreciation by customers. The problem is two-fold: define a desired level of service (queue lengths,...
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...
Dynamic Stochastic Equilibrium Model in Multiple Vehicle Type Transportation Networks
In this study, a multi-vehicle type dynamic stochastic user equilibrium model (called MDSUE model for abbreviation) is developed. By using MDSUE model, the prediction of departure rates...
Dynamic Estimation of Freeway Demand Patterns and a Stochastic Programming Approach to Freeway Ramp Metering
Controlling the rate at which vehicles are allowed to enter a freeway from the freeway's on-ramps has become a standard method for reducing the impact of both recurring and...
Vehicle Lateral Guidance Using a DSP Based Vision System
A practical real-time vision system system which uses a digital signal processing chip to obtain a tracking error for lateral guidance of vehicles at highway speeds is presented. Minor...
Observation and Modeling of Mobile Environment
Perception of the environment in a mobile robot is a difficult task. Other moving objects and various changes in the environment and motion of the robot must be handled together. Control...
Measuring Highway Inventory Features Using Stereoscopic Imaging System
The new stereoscopic measurement approach is discussed in this paper. The objective of this paper is not intended to present another new videologging system. Instead, this paper is to...
Subsurface Pavement Structure Inventory Using Ground Penetrating Radar and a Bore Hole Camera
The Pavement Management System (PMS) is now a necessary pavement evaluation tool. The PMS data base has been historically fed with surface inspection data, but increasing demands for accurate...
Flexible Pavement Distress Evaluation Using Image Analysis
A unique combination of image histogram and projection histogram are employed to classify major distress types on flexible pavement. This technique has taken into account the presence...
Pressure-Treated Wood Effect on Marina Environment
Pressure treated Southern Pine and Douglas Fir are the most commonly used materials for marina construction in the United States. The preservatives currently used, creosote, chromated...
