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...
GRREATdB - GRaphic Roadway Editor and Analysis Tool
This paper describes the development and use of a tool to link textual databases to road network-based interactive graphics. Advantages of the system are discussed. The GRREATdB program...
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...
Computerized Transportation/Financial Planning Processes
The Computerized Transportation/Financial Planning Process (CTFP) comprises a battery of programs that collectively form a valuable growth management tool. CTFP incorporates four spreadsheet...
Incorporating Risk Analysis Into Spreadsheet Forecasts
The risk analysis technique presented overcomes the difficulties of sensitivity analysis by entering key input variables as probability distributions, rather than as discreet values. Using...
Pavement Inventory and Evaluation Systems Using Microcomputer Data Base Managers
The two most commonly used relational DBMS (Data Base Management System) softwares are Ashton-Tate's 'dBASE III Plus', and Microrim's 'R:Base 5000'. This paper illustrates the use of these...
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...
Traffic Congestion Data Collection and Analysis System
The system was developed to allow traffic engineers to analyze the magnitude, duration and location of traffic congestion on highways and city streets. It is used to prioritize traffic...
