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)...

Use of Geographic Information System for Transportation Data Analysis
Origin-destination (O-D) survey data have been usually applied to identify travel characteristics for transportation planning activities. Travel forecasting models are also validated against...

Validation and Application of THE Model's Trip Table Estimation Process
The Highway Emulator (THE) Model is a microcomputer based travel demand forecasting program maintained by the Central Transportation Planning Staff (CTPS). In addition to the traditional...

Transit Network Modelling?A New Approach
London's underground is one of the world's largest heavy-rail underground systems. London underground Limited (LUL) is the main rapid transit operator in London, and is financed directly...

A Microcomputer Program to Evaluate Low Cost Modifications on Urban Freeways
This paper presents a user-friendly, menu-driven microcomputer program, RAMP, for analysis and evaluation of freeway ramp junction level of service. RAMP automates the approximation procedure...

Florida's New Toll Facilities Model
Florida's Turnpike provides a system of user-financed limited access toll highways meeting important transportation needs in the State of Florida, while protecting the interests of its...

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...

Assignment Modeling with Dynamic Traffic Effects
This paper describes the new traffic assignment modeling provided by the Highway analysis component of the TRIPS package. This tackles some fundamental modeling issues regarding the time...

Impact of Land Use Alternatives on Transportation Demand
This paper documents a study conducted by the Baltimore Regional Council of Governments (Regional Council) for the Federal Highway Administration (FHWA). Under this study, alternative...

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...

Trends in Digital Road Map Databases for Microcomputer Applications in Transportation
Advances in the technology and coverage of precision digital road-map database, combined with advances in the size and data processing capacity of microcomputers, are together contributing...

Synthesis of Traffic Signal Timing for the Highway Capacity Manual Planning Analysis
The 1985 Highway Capacity Manual (HCM) provides a technique to analyze the operation of signalized intersections. The Highway Capacity Software (HCS) is a microcomputer package that faithfully...

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...

An Expert System Analysis of the Signal Operational Analysis Package Results
An expert system is a type of artificial intelligence program that captures the human knowledge which is involved in making a decision. Expert systems are very suitable for solving problems...

Development of Self-Organizing Traffic Control System Using Neural Network Model
This paper is concerned with developing a self-organizing traffic control system using a neural network model, a multilayer network model. The neural network inputs the control variables,...

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...

The Integration of the Highway Capacity Manual and the TRAF-NETSIM Simulation Model
The Bureau of Traffic Operations, New York City Department of Transportation (NYCDOT) utilizes for various types of studies and capacity analyses, the 1985 Highway Capacity Methodology...

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...

Large-Truck Safety Decision Support System
Large trucks, defined here as trucks having six or more wheels and a gross weight greater than 10,000 pounds, present a difficult safety problem to our nation's transportation system....
