Geotechnical Practice for Waste Disposal '87
This volume contains 55 papers covering many aspects of geotechnical issues associated with waste disposal. The papers represent advances during the intervening decade since the first...
Fishing the Four-Lane
Recent changes in one Montana canyon have shown that even highways and freshwater fish can happily coexist with the proper planning. Twenty years ago, the Montana Department of Highways...
Activity Center Development Impact Analysis
A flexible microcomputer spreadsheet analysis method is described for analyzing area-wide and localized impacts of new development in urban or suburban activity centers. The analysis approach...
GTRAF: The Netsim Graphics System
This paper describes the development of an interactive computer graphics (ICG) system, named GTRAF, which will provide users with a new and highly efficient methodology for analyzing results...
Development of Graphics Displays for the Integrated Traffic Data System
This paper describes the development of interactive graphics displays for the Integrated Traffic Data System (ITDS) and provides technical details on the hardware and software considerations...
Spreadsheet-Based Queuing Models
This paper describes how microcomputer-based spreadsheet programs, such as Lotus 1-2-3, can be used to implement queuing models of varying levels of sophistication for use in traffic analyses....
Freeway Analysis Using A Micro Version of FREQ
FREQ8PE is a freeway corridor simulation model. It is a batch processing mainframe program written in ASCII FORTRAN IV, which performs three basic functions: simulate freeway queueing,...
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...
Traffic Engineering Data Collection Using Custom Equipment and Microcomputer System Equipment and Procedures
This paper presents experience with various traffic engineering data collection equipment and devices. It presents criteria for the development of a general purpose data collection system....
ROADTEST?A Microscopic Traffic and Transit Simulator
A new computerized microscopic traffic simulation model ROADTEST is described. The model a general purpose one, permits simulation of any vehicles including trains and fixed route transit...
Trip Table Estimation from Observed Traffic Volumes
This estimation technique identifies the most likely trip table to produce a specified set of traffic counts when assigned to a representative highway network. The resultant table is derived...
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...
Traffic and Transport Data Management by Micro-Computer
Dealing with the multiple needs of an adequate traffic and urban transport information system is becoming a manageable task with the software and hardware presently available in micro-computing....
Simulation of Intersections During Reconstruction
In order to make computer simulation of intersections more appealing and easier to use, and interactive, menu-driven micro-computer program, called INTERCON (Michalopoulos and Plum, 1986),...
The Wet Look
The collapse of the Schoharie Creek bridge drew attention to underwater inspection. Underwater inspection of bridges gives engineers a better understanding of the condition of the bridges....
Preliminary Design and Construction Plan for an Ocean Wave Energy Conversion System
A preliminary design and construction plan for a prototype wave energy conversion system is described. While the design methodology and construction procedures are intended for generic...
Taking the Loss Out of Risk
Since Superfund was authorized in 1981 and 22,000 hazardous waste sites put on notice, funds for remedial action have peaked with $20 billion annual clean-up budgets projected. But to...
Impact Fees: Florida's Link Between Growth, Road Improvements, and Financing
Impact fees are one mechanism by which local governments can obtain additional revenue needed to construct major roads demanded by the consequences of new development. In Florida, the...
Surveying for Scour
The public works engineer never knows exactly how many bridge piers and abutments are undermined by erosion due to scour. Massachusetts Department of Public Works needed a rapid method...
New Deep Foundations Cut Costs
Two European innovations in deep foundations are highly competitive in cost, time and material. They are the barrette (slurry wall segment) and the bored pile/caisson which is then grouted...
