Traffic Congestion Data Collection and Analysis System
The system was developed to allow traffic engineers to analyze the magnitude, duration and location of traffic congestion on highways and city streets. It is used to prioritize traffic...
Maximizing Your Use of Interactive Graphics in Transportation Simulation Modeling
The paper discusses the capabilities, through the aid of computer graphics,now that exist to take analysis and reporting of traffic simulation model studies several steps further than...
Dynamic Assignment Modelling with Trips
This paper describes additional ways in which TRIPS models time-varying, or 'dynamic' effects. These include area-wide effects as vehicles move through the network,...
Using GIS Techniques for Transportation Planning to Automate Compilation of Land Use Information
This paper describes a procedure used to compile land use or socioeconomic data for traffic analysis zones for input into a transportation planning model. The procedure uses a combination...
Eutrophication and Nutrient Enrichment in Peconic Bay: Numerical Model of Historical Conditions of the Mid-1970s
In response to water quality and resource management issues triggered by the brown tide bloom of 1985-88 in the embayments of the Peconic estuary of Long Island, New York, a coupled hydrodynamic...
Florida Bridges Beat the Clock
Today, when budget overruns and delays on construction projects are the rule more than the exception, 11 precast segmental balanced cantilever bridges on two contracts were recently completed...
Overhauling and Opening to Traffic of a Toll Tunnel in Marseilles (France)
The city of Marseilles called for bids for overhauling and opening to traffic an old unused railway tunnel, under the very center of the city. The tender scheme was a concession. The paper...
An Example of Privately Funded Project
The paper discusses the proposal of the Syndicat des Transports Parisiens, the local authority in charge of Public Transports in the Paris region, to ask private firms to implement without...
Performance Measures for Irrigation Water Delivery
Performance measures are developed which facilitate analysis of irrigation water delivery systems in light of the objectives of adequacy, efficiency, dependability and equity and of water...
Stream Standards for Toxics and Irrigated Agriculture Using New Mexico as a Case Study
New Mexico follows a policy of 'antidegradation' with respect to the existing quality of a stream, but its standards specifically exclude return flows from irrigated...
Management Practice Effects on Water Quality
An array of resource conservation and water quality issues are providing research challenges and opportunities in soil and water, irrigation, and drainage. The key to addressing these...
Research Need on Integrated System for Water and Pest Management to Protect Groundwater Quality
Research is urgently needed to develop the technology for integrating the methodologies for managing soil, water, ground cover, pesticide applications, and fertilizer applications in such...
Deadly Debris Flows on I-5 Near Grapevine, CA
A series of debris flows inundated the southbound lanes of interstate Highway 5 (1-5) approximately 110 km (70 mi) NW of Los Angeles, California, between Fort Tejon and Grapevine, early...
Phoenix Flood Hydrology for Price Expressway
Recently HDR Engineering, Inc. (HDR) completed a study of the off-site stormwater volumes and peak flow rates for the Price Expressway and Santan Freeway in suburban Phoenix. HDR is the...
Structural Control of Ground-Water Induced Debris Flows
A number of case studies have attributed debris flow initiation to the effect of elevated pore pressure from a bedrock ground-water source. Debris flows on slopes underlain by Precambrian...
Shop Creek Stormwater Quality Enhancement Project
The advent of NPDES regulations for stormwater discharges creates a need to verify, on a regional basis, the effectiveness of emerging water-quality control technologies such as extended...
Evaluation of the ARS Low Drop Grade Control Structure
The ARS low drop grade control structure was developed by Little and Murphy to provide efficient energy dissipation and effective grade control for streams in northern Mississippi. The...
Flow Field Near an Inland Navigation Tow
As a vessel moves through a body of water, disturbances are created in the form of altered water levels such as waves or drawdown and altered flow fields such as increased velocities and...
Data Acquisition for Determining the Physical Impacts of Navigation
Research is being conducted to determine the physical effects of navigation on the Upper Mississippi River System (UMRS). Extensive field data on various aspects of physical effects of...
Prototype Measurements of Flows Induced by Navigation Tows
Present projections of growth of commerical navigation traffic indicate that annual tonnage per tow and/or number of tows will continue to increase through the foreseeable future. In order...
