Using Interactive Simulation to Model Driver Behavior Under ATIS
This paper discusses the development and implementation of FASTCARS (Freeway and Arterial Street Traffic Conflict Arousal and Resolution Simulator), an interactive microcomputer based...
The Permanent Traffic Count Analysis Package
The data management of traffic volume counts can be so overwhelming that limited time and effort is spent collecting and saving traffic counts. With the use of computer technology, however,...
A PASSER II-90 Postprocessor for Detailed Analysis of Arterial Traffic Control Parameters
Many preprocessors have been developed for traffic signal operation software to ease the tedious data input process or to perform error trapping on the input data. However, work to date...
A Calibration Process for Automatic Incident Detection Algorithms
This paper describes the development of a general method for the calibration of Automatic Incident Detection algorithms. A simple structure of freeway traffic data adapted to this process...

Integration of a Traffic Noise Model and AutoCAD
TrafficNoiseCAD represents a new approach to noise analysis and barrier design by integrating file creation for the FHWA STAMINA 2.0 noise prediction program with interactive graphical...
Trip Generation Analysis by Artificial Neural Networks
A new approach for conducting trip generation analysis based on the concepts of artificial neural networks is presented in this paper. First, a brief introduction to the concepts of artificial...
Correction Factor Method for Building Analysis Under Sequential Dead Loads
The effect of the sequential application of dead load due to the sequential nature of construction is an important factor to be considered in the multistory frame analysis. One of the...
Signal Analysis for Quantitative AE Testing
Quantitative acoustic emission (AE) techniques can be used to monitor crack growth and to deduce microfracture mechanisms in quasi-brittle materials. Multichannel data acquisition systems...
Software Applications for Monitoring Instrumentation Data
The initial program for reducing instrumentation data, used by the Geotechnical Branch of the Louisville District Corps of Engineers, was written in 1969. This program did not allow for...
Testing Models of Flow and Transport in Unsaturated Porous Media
The design of an intermediate-scale flow and transport experiment in an unsaturated porous media is described. This experiment will be conducted a 3-m-diameter by 6-m-long caisson filled...
Carbon Isotopic Data from Test Hole USW UZ-1, Yucca Mountain, Nevada
Rock-CO2-gas analyses in test hole USW UZ-1 at Yucca Mountain indicate that gas movement in the unsaturated zone is likely through a dry-fracture...
Carbon-14: Some Evidence of Migration and Experiments on Immobilisation
Carbon-14 that is produced in nuclear reactors by reactions on C, N and O is one of the most biologically dangerous nuclides that are subject to global dispersion (H-3, 85-Kr, 129-I)....
Findings of the Secretary of Energy Advisory Board Task Force on Radioactive Waste Management
Secretary of Energy James D. Watkins created the Task Force on Radioactive Waste Management in April 1991. He asked the group then to recommend measures the Department might take to strengthen...
Determination of Water Content in Unsaturated Flow Experiments Using TDR and Capacitance
Electromagnetic techniques have been used for many years for the determination of moisture content in materials. We are adapting two of these techniques to the estimation of moisture in...
