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,...

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...

Highway Injuries: Our Major Health Problem
Injuries are the leading cause of death in the United States from early childhood until about age 45. Motor vehicles kill more Americans age 1 to 34 than any other source of injury or...

Activity Center Development Impact Analysis
A flexible microcomputer spreadsheet analysis method is described for analyzing area-wide and localized impacts of new development in urban or suburban activity centers. The analysis approach...

Evaluation and Testing of Travel Demand Software
Transportation planners are frequently confronted with issues and concerns related to varying levels of analysis detail. Although microcomputer packages exist to analyze regional, corridor...

Transportation Network Building Using a CAD Interface
This paper illustrates how Barton-Aschman Associates, Inc, has made use of AutoCAD(TRADEMARK) on the microcomputer to digitize an existing highway network and to create a new network from...

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...

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...

Automated People Movers?The Need for Flexibility and Clarity
The Airtrans System at Dallas/Ft. Worth Airport is the best example available of how an automated people mover (APM) might function in an urban setting. An examination of Airtrans shows...

Regional Planning Models Used in Subarea Windows
The typical regional travel-forecasting model has historically been confined to use on a mainframe computer. In an effort to reduce costs and allow computer hardware options, a three-tiered...

Use of a Simplified Urban Traffic Forecasting Procedure for Project Analysis
This paper presents New York State Department of Transportation's experience with the calibration and testing of a simplified procedure for estimating urban traffic at the...

A New Panama Canal?
The Panama Canal is expected to be obsolete by the end of the century. Already there are serious problems with ship traffic through the Canal: volume of traffic is down, average transit...
