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...
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...
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,...
Modeling of Surface Vortices in Unsteady Flow
Hydraulic model studies of lock filling and emptying systems include investigating vortex tendencies at the intake vincinity during filling. The flow at the intake vicinity is unsteady...
Bank Erosion During the 1988-Flood in the Rumoi River
Observations of the bank erosion were performed in the Rumoi River after the flood in August, 1988. It was found from the detailed research that the pattern of the flood was an important...
Three-Dimensional Modelling of Recirculation Behind a Groyne
Extensive investigation on the three-dimensional flow patterns behind a groyne have been carried out in a small-scale experiment. A three-dimensional hydrodynamic numerical model is verified...
Transportation: New Systems for the New Century
By the end of this decade, a new coordinated transportation system for the U.S. could consist of high speed rail, maglev, regional airports and highways built solely for trucks. It would...
Analysis of Local Scouring
An understanding of local scouring is very important for the safety and integrity of hydraulic structures. The location, shape, and magnitude of the scour hole is a function of dynamic...
Channel Changes in the Platte River, 1926?1986
The Platte has changed significantly during the last century. A meandering channel with extensive riparian vegetation growth has replaced, the once braided and unvegetated channel in some...
