Policy Options and Highway Capacity Needs
One of the recurring criticisms levelled against FHWA's Report to Congress on the Status of the Nation's Highways is that the Report does not go far enough in examining the implications...

Validating a Citywide Traffic Planning Model
A traffic planning model can improve the public agency's ability to forecast future traffic and plan appropriate roadway intrastructure. However, the usefulness of these models depends...

Better Ways to Update Trip Matrices
Updating origin-destination (OD) trip matrices usually involves considerable survey costs, so engineers are often forced to use dated OD information, which can seriously undermine the...

Graphical Representation of Signal and Stop Sign Control Warrants Combined with Level of Service Estimates
An insolated intersection is usually controlled by either signals or stop signs. The choice between these two trafic control devices requires an engineering study which typically examines...

A Method for Reviewing and Assessing PASSER II and TRANSYT-7F Signal Timing Optimization Outputs
The development of traffic signal timing plans is a common task. Some of the traffic software programs are the Arterial analysis package (AAP), the Progression Analysis and Signal System...

Using the 1985 HCM, PASSER and TRANSYT in Harmony
Throughout the last decade, the City of DeKalb Engineering Division has embarked on a program to address their highly variable traffic demands with comprehensive signal system projects...

A Microcomputer Model to Estimate the Benefits of Volume Generated Auxiliary Passing Lanes on Two-Lane, Two-Way Highways
Safety and operational characteristics of rural and suburban two-lane roadways can be substantially improved by the provision of adequate passing opportunity, especially as traffic volumes...

Determining Hours of Congestion for Urban Freeways
The concept of Hours of Freeway Congestion is a measure of effectiveness in the evaluation of freeway reconstruction scenarios. The procedure described herein estimates future traffic...

An Interactive Input Data Manager for the TRAF Simulation System
TRAFEdit is an interactive, menu driven program which allows the user to create or modify an input data file for the TRAF simulation system. TRAFEdit is essentially an update to the NEDIT...

Tennessee's Integrated Rural Transit Microcomputer Software
The Tennessee Department of transportation (TDOT) entered into a research contract with Vanderbilt University and the University of Tennessee to develop an integrated series of programs...

Evaluation of Freeway Improvement Alternatives Using CORFLO
This paper describes the application of the CORFLO simulation model on a section of the I-70 freeway in Columbus, Ohio. CORFLO is an integrated traffic simulation system for corridors...

FEDIT? User Interface for FHWA's TRAF-FRESIM^TM Model
This paper presents the FEDIT Data Input Preprocessor for FHWA's soon-to-be-released microscopic freeway simulation program - FRESIM. FRESIM (Halati, 1990, 1991) is a powerful freeway...

Analysis of Vessel and Vehicle Queues at Moveable Bridges
This paper describes procedures and the analysis developed to evaluate three different replacement options for the existing S.E. 17th Street Causeway moveable bridge which crosses the...

Estimating Load Impacts on Highway Structures Using the National Bridge Inventory Database
The issuance of single and multiple permits to operate vehicles exceeding legal weight limits, along with the policy-level analysis of bridge impacts induced by changes in vehicle size...

An Integrated System for Evaluation, Rating and Management of Bridges
This paper describes a software system that can effectively be used in bridge management and planning. The system integrates several modules each capable of conducting a specific task...

Automation of Design at the New Denver Airport
This paper outlines an innovative approach to automating the roadway design process by linking design and drafting with multiple software programs and taking advantage of the strengths...

Grading Design Using CADD: Denver International Airport Roadways
Using the terminal access roadway site for the new Denver International Airport as an example, this paper outlines a method for automating the preparation of grading plans and computation...

A Highway Maintenance Operation Database
This paper presents the major findings of a study to develop a system design for the implementation of an electronic network which uses personal computers in local highway maintenance...

General Purpose Microcomputer Software for Transportation Engineering Applications
A transportation agency or firm faces the challenge of being suitably equipped to gather, reduce, and analyze large amounts of data. The organization must then communicate the meaning...

Software Utilities for Traffic Simulation Models
Simulation models of traffic flow on highways are increasingly becoming the choice of many analysts and traffic engineers as analytical tools to test, evaluate and implement traffic control/management...
