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...

Census Data in Travel Demand Model Development
The New Jersey Department of Transportation purchased the Statewide 1980 Census Urban Transportation Planning Package (UTPP) and began offering this information to other Government Agencies...

Downloading Baltimore Regional Databases
The Regional Planning Council (RPC) now is exploring through trial-and-error, the most effective, efficient means of performing travel demand forecasts cooperatively with its 'clients....

A Travel Demand Modeling System for Istanbul
This paper describes the development and application of a microcomputer-based travel demand modeling system as part of an 18-month planning and feasibility study for the Istanbul Metro...

Distributed Graphical Transit Scheduling System
The Graphical Scheduler is the latest of software products developed by SAGE for the transit industry. It was specifically designed to run on a micro-computer taking advantage of the latest...

Studies of Long-Term Water Losses
The water-loss time series are formulated for the studied watersheds in the Ohio River Basin through the use of the law of water balance to the system inputs and corresponding outputs....

Intelligent Central Database System for Synchronized Distributed Processing of Large Hydrologic Packages in Local Area Networks
The nodes of a local area network can be dedicated to the independent routines of a large hydrologic/hydraulic package. The server of the network can be dedicated to the control of the...

Multivariate Modeling of Hydrological Time Series for Generation of Reservoir Operating Rules
A multivariate model and a disaggregation model are used in this study to generate annual and monthly time series of streamflow data for multiple sites. The parameters of the models are...

Hale Cycle and Indian Drought and Flood Area Indices
The Indian Drought (DAI) and flood (FAI) area indices have been argued to be related to the hale cycle of sunspot number by H. N. Bhalme and D. A. Mooley. They studied the dependence between...

Rehabbing under Traffic
Redecking the Golden Gate Bridge with a light weight orthotropic steel plate deck left the 49 year old monument 11,000 tons lighter, 2 feet wider, and ready to carry traffic for the next...

Street Fares
An argument is made for imposing user fees to amass funds for repair and maintenance of local roads and streets. These infrastructure services have to compete for local general property...

How to Use a Transit Consumer Information System
This paper reports the results of an effort to implement a consumer information system in a small urban area. The system was designed to periodically report the travel patterns and viewpoints...

Time Dependent Material Properties Due to Solute Redistribution in Frozen Marine Soils
The design of earth structures and foundations in arctic marine environments requires the assessment of soil properties. A study is presented which investigates the change in mechanical...

Foundation Response of Arctic Structures to Time-Dependent Ice Loadings
Arctic structures are subjected to a variety of time-dependent loadings, the most important of which are those due to ice. An approach is presented for estimating the strength and deformation...

Quality Control Management of Real-Time Data
Recent improvements in the real-time acquisition of hydro-meteorological data have raised concerns regarding the quality of the data received. This paper presents several data verification...

Managing a New Start Rail Transit Agency
In 1982 the Southern California Rapid Transit District (RTD) was facing two major challenges. A Policy and Management Plan was developed to meet these two major challenges. The Policy...

Time Series Analysis of Hourly Domestic Water Demand
Design flows for water supply and sanitary sewer systems are chosen by rules of thumb in the absence of actual data. This research develops two stochastic models of water demand by analyzing...

Real-Time Data Verification
Recent improvements in the real-time acquisition of hydro-meteorological data have raised concerns regarding the quality of the data received. Water users having practically instant access...

Hydrologic Work Group System Using Distributed Task Processing
The notion behind work group systems is that a collection of co-workers, numbering from a few to a few tens of people, is the logical unit around which to build a centralized microcomputer...

A Computer Aided Approach to Missing Time-Series Data Replacement
The objective of this research is to design, construct, and demonstrate a computer utility which will interactively aid the time series researcher in choosing an appropriate missing data...
