The Use of COGO/GIS in the Route 58 Corridor Development Study: A Case Study
This paper is a case study in the utilization of COGO and GIS software for the Route 58 Corridor Development Program in Southwest Virginia. The planning effort included the evaluation...
Geographic Information Systems for Highway/Sign Maintenance
Geographic Information Systems (GIS) can be a key element toward achieving improved management of all transportation facilities for municipal and state Departments of Transportation (DOT)...
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...
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...

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-FRESIMTM 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
