The Small Computer Accident Records System (SCARS)
SCARS was developed to support public agencies in Florida in their efforts to analyze traffic accident records and identify high hazard locations. It is an application of the DBASE III+...
California DOT CADD
Starting in 1983 the California Department of Transportation (Caltrans) embarked on a project to incorporate current computer technology into the project development process. Today the...
Collection and Analysis of Speed and Delay Using Portable Microcomputers
Speed and delay studies are performed routinely on urban street networks. The data are used for a variety of transportation engineering purposes including signal timing design, roadway...
Data Collection Using a Portable Computer and Digitizing Tablet
This paper describes a data collection system developed by the New Hampshire Technology Transfer Center. The key features of this data collection method are its ease of use, single step...
Traffic Simulation and its Graphic Presentations
A computer simulation program for traffic signal timing design was developed. The program can provide some appealing graphic presentations not only of input data but also of output results....
A Graphical Database for Transportation Systems
A graphical database composed of programmable objects analogous to elements of a physical plant of a transportation network is presented. The discussion reviews the application of a graphical...
U.S. Geological Survey DLG-3 and Bureau of the Census TIGER Data: Development and GIS Applications
The U.S. Geological Survey has been actively developing digital cartographic and geographic data and standards since the early 1970's. One product is Digital Line Graph data, which offer...
Census Data Available for Transportation Planners
In 1981 the U.S. Bureau of the Census set a goal to automate the full range of cartographic and geographic processes in time to serve the data collection, tabulation, and dissemination...
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...
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...
The Use of Prototyping and Graphical Methods for Road Information and Management Systems
Graphics approaches to Pavement Management Systems offer a substantial aid to the early acceptance of and accessibility to the Road Information Systems presently available. The Apple Macintosh...
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...
Transit Scheduling Using Computer Graphics
Graphical scheduling has been very popular throughout the world, but until recently, has not been available for a computerized scheduling system. Computerized graphical scheduling systems...
Scheduling Fixed Route Bus Services Using Simulation
The paper discusses the development and applications of a Monte Carlo simulation Program (BUS - MONITOR) for estimating and evaluating the quality of service of fixed route, many to many...
