Reliability-Based Estimates of Wetland Detention Times for Wastewater Treatment
Determination of the hydraulic residence or detention time is often the first step in design of wetlands constructed for wastewater treatment. Current methods for estimating wetland detention...
Atlantic Salmon Smolt Movement and Behavior at Vernon Hydroelectric Station
Behavior of emigrating Atlantic salmon smolts (Salmo salar) was studied at New England Power Company's (NEP) Vernon Hydroelectric Station located on the Connecticut River,...
Double-Decking the Freeways
Elevated highways cost more than at-grade construction. Nonetheless, the hidden costs of increased traffic congestion and the real cost of urban right-of-way make elevated highways feasible....
A Fleet Management System for Road Transportation
In this paper, an architecture for a fleet management system for road transportation companies is being proposed. This fleet management system integrates planning support with mobile communications...
Routing Based on Anticipated Travel Times
The routing of drivers based on anticipated as well as instantaneous link travel times has presented route guidance system developers with an opportunity to achieve additional IVHS benefits...
Bus Pre-Emption: A Real Time Control Strategy for Privatized Transit Operation
Bus pre-emption strategies are designed to provide priority to transit buses over passenger cars for urban travel. A comparative analysis of a proposed suburban bus service for regular...
Dynamic Estimation of Freeway Demand Patterns and a Stochastic Programming Approach to Freeway Ramp Metering
Controlling the rate at which vehicles are allowed to enter a freeway from the freeway's on-ramps has become a standard method for reducing the impact of both recurring and...
Time Dependent Stochastic Characteristics of the Lateral Random Vibration of Tall Structures with Circular Cross-Section
From full scale measurement of the pressure field at three levels of a concrete chimney with 230 m height the lift coefficient is deduced and the lateral oscillation is investigated. The...
Objective Comparison of Fatigue Crack Growth Laws
This paper presents objective criteria for choosing between different fatigue crack growth laws to represent a material's fatigue behavior based on a data set containing multiple...
Conductivity and Transit Time Estimates of a Soil Liner
A field-scale soil linear was built to assess the feasibilty of constructing a liner to meet the saturated hydraulic conductivity requirement of the U.S. EPA (i.e., less than 1 ? 10-7...
Focused Model Approach for Corridors and Subareas
A focused modeling approach utilizes calibrated model parameters and inputs from a regional model, yet allows the flexibility to quickly test land use, network and other policy alternatives....
A Package for Travel Demand Forecasting on The Macintosh
This paper introduced a package which may be the first to be developed for travel demand forecasting on the Macintosh. Features of the package and its capabilities are demonstrated through...
Microcomputer Capabilities for Trip Table Estimation and Peak Hour Assignments which Consider Peak Spreading
The microcomputer-based TRANPLAN transportation planning package has been expanded to include a trip table estimation procedure and an equilibrium traffic assignment model which simulates...
Microcomputer Assisted Transportation Impacts Analysis: Hudson River Waterfront Development
Across the Hudson River from Manhattan, major office and residential developments are occurring on large tracts of former railroad and shipping properties in New Jersey. Much of this development...
Using Lap Tops as Connections to Minicomputers in the City of Portland
Over the past few years, the City of Portland has used a mix of personal computers and minicomputers to accomplish its mission. This paper describes four applications of using lap top...
Synthetic O-D Microcomputer Trip Table Packages
Three microcomputer models for synthetic estimation of origin-destination trip tables are compared based on theoretical foundations, implementability, and operating performances. Each...
InTransit: Processing and Analyzing Transit Service Data with the Macintosh
InTransit is a database application based on 4th Dimension designed to facilitate the data processing and analysis phases. InTransit, in its present form, can process both ridecheck and...
Processing Automatically Collected Patronage Data
Since the late 1970's, the San Francisco Bay Area Rapid Transit District (BART) has had the capability to automatically collect trip origin and destination data from its faregates. This...
Advances in Trip Matrix Estimation
The derivation of Origin-Destination (O-D) trip matrices is a vital component of much transportation planning. Obtaining accurate O-D data often poses a challenge on account of the large...
Computer Analysis of Origin-Destination Survey Data in the State Route 55 Travel Corridor, Before and After the Opening of Carpool Lanes
The State Route (SR) 55 carpool lanes in Orange County were opened for high occupancy vehicles (HOV) usage in November, 1985. Since SR 55 was the first travel corridor in Orange County...
