Reconstruction Under Traffic: A Study of Some Effects of the Dan Ryan Project on Motor Carrier Operations in Northeast Illinois
The paper discusses preparations by the Chicago Area Transportation Study for a study of the operational responses of truckers to whatever effects upon the regional highway system are...

The Truck Commodity Survey in the New York-New Jersey Metropolitan Area
The Truck Commodity Survey was designed to gather information on the characteristics of truck traffic at toll barriers with minimal disruption to traffic flows. It was developed by the...

Truck Involvement in Fatal Urban Road Accidents in Australia
Trucks are over-represented (relative to vehicle numbers and vehicle-kilometers of travel) in fatal accidents. Those most at risk are occupants of other vehicles and pedestrians. Articulated...

Fast Track Paving May Offer Applications to Structures
'Fast Track' is a technique that permits portland cement concrete pavements to be opened to traffic in a day or less after they are poured. The method has been...

Fast-Track Concrete Paving
Well known for its corn production, the State of Iowa has been seeding a new product for the past several years. 'Fast Track' concrete has grown along the edge...

Early Opening of Concrete Pavements to Traffic
Current practice for opening slab replacements and full-depth repairs to traffic ranges widely from 2 hours to several days. A rational and simple procedure is urgently needed for determining...

Hydrogeology Comes to the Surface
Before concluding whether groundwater is safe or contaminated, engineers must understand the science of hydrogeology. If they don't understand hydrogeology, unnecessary and...

Reliable Displacements from Integrated Quick-Release Accelerograms
A new baseline correction method has been developed which allows accelerograms collected during quick-release tests of full scale structures to be doubly integrated to displacements. The...

Goods Transportation in Urban Areas
The conference on Goods Transportation in Urban Areas (GTUA V) held in Santa Barbara, California, during March 6-11, 1988, focused on three major themes?truck accommodation in urban areas;...

Hazardous Waste Impacts on the Highway Planning and Property Acquisition Process
Since the advent of increased public awareness concerning hazardous waste and the enactment of statutes governing these wastes, hazardous waste has become an important component impacting...

The MSU Sprinkling Infiltrometer: A Device to Measure Time-to-Ponding
Time-to-ponding can be determined quickly and with minimal disturbance to the soil surface by the use of a sprinking infiltrometer developed at Michigan State University (MSU). Solenoid...

Vessel Induced Physical Effects in a Navigation Channel
The U.S. Army Corps of Engineers is investigating ways to improve lockage efficiency at the Marmet Locks on the Kanawha River, West Virginia. A physical effects prediction model have been...

Programmable Logic Controller Based Governor/Plant Controller
This paper discusses the performance characteristics of the programmable logic controllers (PLC's) is based governor, particularly speed resolution and response times. The...

The Race for Smart Cars
Prendergast describes the technological elements involved in Intelligent Vehicle/Highway Systems (IVHS), current programs in Europe, Japan and the U.S. aimed at implementing IVHS systems,...

Affordable Housing
a Challenge to Civil Engineers
This conference proceedings, which consists of 25 papers presented at the National Conference on Affordable Housing held in Miami, Florida on December 6-8, 1989, discusses ways that the...

Real-time Monitoring of Heavy Equipment in Open Pit Mines
This paper reports on a system with local intelligence to interpret on-board signals. Existing sensors, pressure switches, warning lights, relays, and on-board monitoring systems provide...

Flow Calculation in a Francis Runner
The flow through a Francis runner has been analysed theoretically. The flow calculations have been carried out by use of an inviscid 3D computational method solving the Euler-Equations....

The Design and Operating Experience of a Multiplexer Application in Conventional Hydro Powerhouse Control
The design of the Bonneville Second Powerhouse control system presented an opportunity to replace conventional cables with a multiplexer system that would provide a two-way data communication...

Capabilities of Automated Control System Employing Advanced Programmable Controllers
This paper details Voith Hydro's range of experience in the use of Programmable Logic Controllers (P. L. C. 's) in the automation of new hydro electric sites....

Highway Factors in Truck Wrecks
An examination is presented of highway factors as they interact with driver and vehicle factors in large truck accident causation. Examples of highway defects are discussed along with...
