Case Studies of Displacement-Induced Fatigue
The potential for displacement-induced cracking is a result of the co-existence of two conditions: an abrupt change in stiffness and a periodic force opposing it. Case studies of retrofitted...
Sewer-Septic Tank Hybrid Promises Savings
Until recently the only options for sewage were the septic tank/leach field or conventional sewers. In some cases a hybrid of the two, called the septic tank/effluent drain, is less costly...
Intelligent User Interface for Network Signal Optimization Programs
This paper presents the design philosophy and program intelligence used in EZ-TRANSYT and EZ-SIGOP, powerful multi-window input data managers for TRANSYT-7F and SIGOP-III, respectively....
SIDRA?An Australian Program for Signalised Intersection Analysis
As more complicated signal phasing systems have been implemented in practice, the analysis methods have moved from a phase-control philosophy applied to approach roads to a group-control...
A Decision Support System for Freeway Corridor Analysis
When the scope of a particular corridor study dictates the review and analysis of a relatively large number of road segments along major transportation corridors, the integration of roadway...
KSLAD: A Traffic Accident Data Analysis Program
Originally developed to run within the dBASE III (tm) operating environment, Kansas Local Accidents Database (KSLAD) has since been upgraded to operate under dBASE III Plus (tm). Work...
Microcomputers in Traffic Operations and Safety: Implementation Lessons for Small Agencies
This study develops and demonstrates microcomputer software for highway safety and traffic operations which meets the needs of small transportation and public works agencies. The study...
Evaluation and Testing of Travel Demand Software
Transportation planners are frequently confronted with issues and concerns related to varying levels of analysis detail. Although microcomputer packages exist to analyze regional, corridor...
NEDS?Network Editing and Display for TRANPLAN
This paper explores some of the current and possible future applications of interactive graphics packages to the tasks of analyzing and planning transportation systems. The source of the...
County-Level Planning Model in Atlanta Region
Gwinnett County is working with the Atlanta Regional Commission (ARC) and Barton-Ashman Associates to download the ARC trip tables for use in a microcomputer transportation planning model...
A Travel Demand Modeling System for Istanbul
This paper describes the development and application of a microcomputer-based travel demand modeling system as part of an 18-month planning and feasibility study for the Istanbul Metro...
Teacher Friendly Transportation Programs
This contribution describes a set of computer programs that has mainly been developed to demonstrate operating and possibilities of mainframe programs during lectures. The program set...
Use of Transport Models in Airport Access Analysis
This paper describes transportation models built by Wilbur Smith and Associates (WSA) as part of a study of Newark International Airport (NIA), conducted for the Port Authority of New...
CAD Generation of Accident Diagrams for Local Agencies
This paper reviews one such issue, safety, focusing on the development of a user-interface with a microcomputer CAD system. With this interface, the system is used to generate collision...
Photogrammetric Analysis Using a Personal Computer
In many cases, photographs of the accident scene taken soon after the event contain visible evidence of road marks and/or debris. By the time the case reaches the accident investigator/reconstructionist,...
Subarea Planning Using Microcomputers
This paper presents the basic features of a subarea focusing program developed by JHK & Associates through a contract with the U. S. Department of Transportation. The program is...
A Comparative Study of Two Capture Chamber Geometries
Results of an experimental study of two capture chambers are presented. The capture chamber geometries are those that have been either used or recommended in conjunction with pneumatic...
Solution to a Waterhammer Problem: A Case Study
Waterhammer is caused by a rapid change in the flow velocity of liquid in a pressurized pipeline. Therefore, the potential for waterhammer exists in almost every pressurized liquid piping...
Evolving Strategic Management Processes at State and Regional Transportation Agencies
Recent progress and accomplishments in strategic planning/management at four transportation agencies: the Pennsylvania Department of Transportation, New Jersey Transit Corporation, New...
Modification and Evolution of Strategic Planning to Fit a Public Agency Environment
