Modeling Permissive Movements in TRANSYT-7F
Traffic Network Study Tool (TRANSYT-7F) is one of the most widely used traffic flow analysis and traffic signal timing optimization models in the United States and elsewhere. Through 'Release...

Intelligent User Interface for Network Signal Optimization Programs
This paper presents the design philosophy and program intelligence used in EZ-TRANSYT and EZ-SIGOP, powerful multi-window input data managers for TRANSYT-7F and SIGOP-III, respectively....

SIDRA?An Australian Program for Signalised Intersection Analysis
As more complicated signal phasing systems have been implemented in practice, the analysis methods have moved from a phase-control philosophy applied to approach roads to a group-control...

Estimating Future Traffic Volumes at the Intersection Level
This paper uses the experience gained on a number of regional and sub-area studies in the northeast to illustrate how measured and forecast traffic information can be combined to predict...

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...

Spreadsheet-Based Queuing Models
This paper describes how microcomputer-based spreadsheet programs, such as Lotus 1-2-3, can be used to implement queuing models of varying levels of sophistication for use in traffic analyses....

Freeway Analysis Using A Micro Version of FREQ
FREQ8PE is a freeway corridor simulation model. It is a batch processing mainframe program written in ASCII FORTRAN IV, which performs three basic functions: simulate freeway queueing,...

A Decision Support System for Freeway Corridor Analysis
When the scope of a particular corridor study dictates the review and analysis of a relatively large number of road segments along major transportation corridors, the integration of roadway...

Real Time Vehicle Systems Monitoring
The system, which has recently been developed, consists of onboard vehicle micro-processor monitoring, data reduction and transmission components, a VHF or satellite communications link,...

ITEEMS: Reducing Mainframe Systems to Micro-scale
The Integrated Traffic Engineering and Enforcement Monitoring System (ITEEMS) is a microcomputer-based system which has an on-line display and analysis of accident records by street intersection,...

Conversion of the MIDAS Accident Analysis Model
The MIDAS (Michigan Dimensional Accident Surveillance) System has been developed to provide accident analysis capability. A microcomputer version of MIDAS is being developed to make the...

KSLAD: A Traffic Accident Data Analysis Program
Originally developed to run within the dBASE III (tm) operating environment, Kansas Local Accidents Database (KSLAD) has since been upgraded to operate under dBASE III Plus (tm). Work...

Highway Safety Analysis and Monitoring
The Highway Safety Analysis and Monitoring (HISAM) software was developed under a Federal Highway Administration research contract and is designed to aid local agencies with data base...

Microcomputers in Traffic Operations and Safety: Implementation Lessons for Small Agencies
This study develops and demonstrates microcomputer software for highway safety and traffic operations which meets the needs of small transportation and public works agencies. The study...

A Model for Analyzing Large Transportation Networks on a Microcomputer
The Pedestrian Level of Service (PEDLS) model combines the best features of spreadsheet programs - their ease of use for inputting data and producing printed output reports - with the...

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...

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....

County-Level Planning Model in Atlanta Region
Gwinnett County is working with the Atlanta Regional Commission (ARC) and Barton-Ashman Associates to download the ARC trip tables for use in a microcomputer transportation planning model...

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...

Computerization of Transit Performance Evaluatio
