Recycling on the Mississippi
Changes in the Mississippi River's water depth and alignment are forcing the retirement of the 105-year-old Hannibal, Mo. swing bridge. Although the bridge's...
Masonry Carries the Load
Engineers frequently have preconceived notions about building materials. Masonry, for example, is commonly selected by architects for its color and texture, rather than by engineers for...
Fire Testing of Shotcrete Samples in a Small Furnace
The fire resistance behaviour of 8 shotcrete samples were investigated in a laboratory furnace applying ISO 834 standard test. Shotcrete was applied on 20 to 30 cm thick granite slabs...
Design of Shotcrete Linings at the Channel Tunnel
Shotcrete is one of the essential support elements of tunnels driven according to the principles of the New Austrian Tunnelling Method (NATM). Whereas originally the NATM was mainly based...
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...
Policy Options and Highway Capacity Needs
One of the recurring criticisms levelled against FHWA's Report to Congress on the Status of the Nation's Highways is that the Report does not go far enough in examining the implications...
A Method for Reviewing and Assessing PASSER II and TRANSYT-7F Signal Timing Optimization Outputs
The development of traffic signal timing plans is a common task. Some of the traffic software programs are the Arterial analysis package (AAP), the Progression Analysis and Signal System...
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...
Evaluation of Freeway Improvement Alternatives Using CORFLO
This paper describes the application of the CORFLO simulation model on a section of the I-70 freeway in Columbus, Ohio. CORFLO is an integrated traffic simulation system for corridors...
FEDIT? User Interface for FHWA's TRAF-FRESIMTM Model
This paper presents the FEDIT Data Input Preprocessor for FHWA's soon-to-be-released microscopic freeway simulation program - FRESIM. FRESIM (Halati, 1990, 1991) is a powerful freeway...
The Traffic Operations Control Center Simulator
As a part of a national effort to improve the operatinal efficiency of the highway network, the California Department of Transportation (CALTRANS) is developing and implementing general...
Historical Pavement Management Database Feasibility Study
Technological and operational issues related to implementing a historical database to support the South Dakota Department of Transportation's current and future pavement management activities...
Automation of Design at the New Denver Airport
This paper outlines an innovative approach to automating the roadway design process by linking design and drafting with multiple software programs and taking advantage of the strengths...
Grading Design Using CADD: Denver International Airport Roadways
Using the terminal access roadway site for the new Denver International Airport as an example, this paper outlines a method for automating the preparation of grading plans and computation...
CADD Applications in Transportation: Beyond Highway Design
Computer Aided Design and Drafting (CADD) software have become very prominent in the design of transportation facilities. There are currently a number of third party packages that operate...
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...
Tutorial on Computer-Aided Design
These tutorial sessions are designed to provide a basic introduction to the use of Computer-Aided Design/Drafting (CAD) in transportation engineering, with particular regard to Civil Engineering...
The Use of Linked Spreadsheets as a Transportation Problem Solving Tool
Spreadsheet modeling is a useful tool for business as well as engineering applications. Until the advent of linked spreadsheets this type of modeling was based on the concept of preparing...
A CADD Program for Simulating Turning Vehicles
The turning capability of one or more 'design' vehicles and their swept paths has a significant influence on the layout of transportation facilities such as roadway intersections, parking...
Regulatory Views on Seismic and Fault-Displacement Parameters Needed for a Geologic Repository Design
This paper presents the regulatory views of the U.S. Nuclear Regulatory Commission staff on some of the significant issues related to the seismic and faulting design of a geologic repository....
