World Bank's HDM-PC: A Microcomputer Aid for Road Planning and Management
HDM-PC, a microcomputer adaptation of the mainframe Highway Design and Maintenance Standards Model (HDM-III), is a powerful analytical tool for the engineering-economic evaluation of road...
Economic Analysis of Local Highway Maintenance
This paper presents a computer program which uses the present worth of life-cycle costs as a basis to select the most cost-effective maintenance strategy to apply to local highway pavements....
Arterial Traffic Flow in Construction Zones
Previously, NETSIM (NETwork SIMulation model) was the only available simulation model that could investigate a wide mix of traffic control and traffic management strategies for a network...
Validation of a Traffic Modeling System for Detour Planning
The Downtown Seattle Transit Project (DSTP) was initiated as an effort to relieve existing traffic congestion in downtown Seattle. It consists primarily of a 1.3-mile electric-bus tunnel...
A Microcomputer Based Pavement Design Program
This paper describes a newly developed pavement design program. The performance of a number of pavement structures are projected over the analysis period. Structurally adequate designs...
The Financial Analysis of a Transportation Project on a Microcomputer
The economics of a future rail transit project are analyzed. Pro forma financial statements are constructed to the year 2002. A number of financial ratios are examined to assess the project's...
A Microcomputer Methodology for Parsimoniously Structuring a Set of Activities
The paper develops a systematic methodology to aid in the identification and rapid structuring of a system of activities. In essence, the user is asked to supply only the names of the...
A User-Friendly Capital Programming Tool for Highway Maintenance Districts
The Roads and Waterways Administration of Finland is developing a microcomputer system, called the Project Analysis System (PAS), to help district engineers in their annual preparation...
An Airport Economic Impacts Model
The paper discusses the development of a basic airport economic impacts model that could be used by any airport. The model was set up on a Lotus 1-2-3 spreadsheet, and requires input information...
Microcomputer Financial Planning for Transportation
This paper describes the development, testing, and application of a microcomputer financial analysis model called the Transit and Highway Revenues and Improvement Forecasting Templates...
Scheduling Fixed Route Bus Services Using Simulation

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...
Transit Route Planning Using Data Downloaded from UTPS
A comprehensive evaluation of alternative bus routing and service patterns was recently performed for the Alameda-Contra Costa (AC) Transit District, the principal public transit operator...
A Matching Algorithm That Eliminates the Need for Radio Signposts in Automatic Passenger Counters on Buses
Volumes of raw data collected using the Automatic Data Aquisition system are useless until they can be processed and transformed into meaningful reports and plots. This is done using a...
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...
