Fortification of MMOC Models for Steep-Channel Flows
The Multimode Method of Characteristics(MMOC), designed to solve unsteady flows, is a new comprehensive scheme formulated by merging several individual characteristic schemes of the specified-time-interval...
Numerical Modelling and Laboratory Verification for the Turbulent Flow Field in the Branching Channel
Adopting the depth-averaged k-? turbulence model and using the finite volume method and SIMPLE procedure, the turbulent flow field in the branching channel is numerically solved and verified...
Thermo-Hydrodynamic Modelling of the Chicago Sanitary and Ship Canal
A one-dimensional numerical model of the Chicago Sanitary and Ship Canal and Lower Des Plaines River has been developed as a tool for assessment of the waterway's thermal response to actual...
Water Quality Enhancement Technology for River-Reservoir Systems
Water quality enhancement technology is applied to a wide variety of field conditions in surface waters including rivers, lakes and reservoir epiliminia, lake and reservoir hypolimnia,...
The New Clark Bridge: Saddle-Draped Cables
The new $85 million, 108 ft wide Clark-Bridge replaces a 20 ft wide 1928 truss bridge at Alton, Ill., carrying US 67 over the Mississippi about one mile above the recently completed Lock...

America's Pavements: World's Longest Bathtubs
Pavements are the most unusual structures designed by civil engineers. Water flows through their tops, bottoms and sides but because pavements are relatively flat, flows out again very...
Historic Yorktown: New Bridge Keeps Old Design
In historic Yorktown, Va., the best solution to reconstructing an obsolete 1952 bridge was to keep its unique design while widening it for '90s traffic. Like the original,...
Gateway to Columbus
The Columbus Gateway Arch Bridge is an innovative twin ribbed steel arch structure with a post-tensioned composite concrete deck, transverse post-tensioned composite steel box girders...
Concrete over the Connecticut
The existing Baldwin Bridge carrying I-95 across the Connecticut River between Old Lyme and Old Saybrook, Connecticut, constructed in 1948, is functioning at maximum capacity with modern...
Using Geographic Information Systems for Traffic Control Inventory Management
Present city traffic control inventory systems lack flexibility, user friendliness, and many have become obsolete because they were originally designed in haphazard ways - thus providing...
A GIS-Based Program Management System: An Approach to Integrate Transportation Management Systems
The Intermodal Surface Transportation Efficiency Act passed by Congress in 1991 requires transportation agencies to develop six management systems that will guide state and local official...
Validation and Application of THE Model's Trip Table Estimation Process
The Highway Emulator (THE) Model is a microcomputer based travel demand forecasting program maintained by the Central Transportation Planning Staff (CTPS). In addition to the traditional...
Estimating Network Model Parameters from Mail Survey Data
Network models are generally based on a four-step modeling process; trip generation, trip distribution, modal split, and trip assignment. Microcomputer implementations of these steps have...
A Microcomputer Program to Evaluate Low Cost Modifications on Urban Freeways
This paper presents a user-friendly, menu-driven microcomputer program, RAMP, for analysis and evaluation of freeway ramp junction level of service. RAMP automates the approximation procedure...
Florida's New Toll Facilities Model
Florida's Turnpike provides a system of user-financed limited access toll highways meeting important transportation needs in the State of Florida, while protecting the interests of its...
Corridor Analysis Using QRS II Route 9 Case Study
This traffic modeling project is part of a larger planning study of the Route 9 corridor through the Town of Hadley and parts of Amherst and Northampton. The Pioneer Valley Planning Comission...
Assignment Modeling with Dynamic Traffic Effects
This paper describes the new traffic assignment modeling provided by the Highway analysis component of the TRIPS package. This tackles some fundamental modeling issues regarding the time...
Validating a Citywide Traffic Planning Model
A traffic planning model can improve the public agency's ability to forecast future traffic and plan appropriate roadway intrastructure. However, the usefulness of these models depends...
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...
