Modeling Ecological Impacts of Destratification
Artificial destratification has long been advocated as a means of improving water quality in lakes and reservoirs. The results have been varied with examples of both water quality improvement...
A Thousand Points of Data
Significant cracking was discovered in a multistory parking garage shortly after construction. Was it safe to open? Based on visual inspection, a bridge was down-rated, with potential...
Minimizing the Probable Maximum Flood
A newly-developed probable maximum precipitation (PMP) estimate for Wisconsin and Michigan reduced precipitation depths by 20%. Should a given area's probable maximum flood...

GIS Application for Post Earthquake Investigation
The Post Earthquake Investigation Team (PEQIT) at the Office of Structure Design, Division of Structures, CALTRANS, has been organized since the 1971 San Fernando earthquake. It is an...
Using GIS to Define and Develop TAZ Data
GIS permits users to geographically display database information. It also can provide a common link between two or more previously unrelated databases. Increasingly, these capabilities...
Use of Geographic Information System for Transportation Data Analysis
Origin-destination (O-D) survey data have been usually applied to identify travel characteristics for transportation planning activities. Travel forecasting models are also validated against...
Travel Demand with Forecasting Microsimulation
Transportation planners forecast travel demand using techniques that are based on dissagregate models estimated from cross-sectional data. Their forecasts are usually single future time...
Better Ways to Update Trip Matrices
Updating origin-destination (OD) trip matrices usually involves considerable survey costs, so engineers are often forced to use dated OD information, which can seriously undermine the...
Trends in Digital Road Map Databases for Microcomputer Applications in Transportation
Advances in the technology and coverage of precision digital road-map database, combined with advances in the size and data processing capacity of microcomputers, are together contributing...
Real-Time Delay Measurement and Intersection Analysis System
Two intersection delay measurement approaches are developed, and a framework for a real-time traffic signal data collection and intersection operational analysis system is presented. The...
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...
A Maintenance Management System for Highways & Urban Streets
This paper describes the establishment of a comprehensive management system for highways and urban streets of Dubai in the United Arab Emirates. In this important United Nations project...
An Integrated System for Evaluation, Rating and Management of Bridges
This paper describes a software system that can effectively be used in bridge management and planning. The system integrates several modules each capable of conducting a specific task...
Transport and Communications Information System for Africa
The Transport and Communications Information System for Africa (TCISA) is a customized microcomputer-based prototype information system for planning transportation and communications in...
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...
