A Two-Way Traffic Feasibility Analysis
This paper presents the findings of a traffic planning feasibility analysis of the expected operational characteristics and traffic impacts related to the proposed conversion of Hennepin...
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...
CADD Applications in Transportation: Beyond Highway Design
Computer Aided Design and Drafting (CADD) software have become very prominent in the design of transportation facilities. There are currently a number of third party packages that operate...
Transport and Communications Information System for Africa
The Transport and Communications Information System for Africa (TCISA) is a customized microcomputer-based prototype information system for planning transportation and communications in...
Validating Expert System Prototypes Using the Turing Test
This paper describes the Turing Test technique to formalize the expert system validation process using a mature microcomputer based prototype expert system that has been developed to perform...
Improving the Graphical Interface in Transportation Planning Software
This paper examines the general issues that drive the development of graphics as a medium for transportation planners. Transportation planning has changed over time, and so has the nature,...
Methodology for Determining Vehicle Usage and Speeds for Mobile Source Emissions Inventories
This paper was published by the Baltimore Regional Council of Governments to document its work in preparing data from its regional road model for input into a computer emissions inventory...
Integration of a Traffic Noise Model and AutoCAD
TrafficNoiseCAD represents a new approach to noise analysis and barrier design by integrating file creation for the FHWA STAMINA 2.0 noise prediction program with interactive graphical...
An Expert System for Stop-Controlled Intersection Design
In 1915, the first stop sign was installed in Detroit, Michigan, but until now, there was still no one coordinated body of knowledge which would dictate design and analysis requirements....
Tutorial on Computer-Aided Design
These tutorial sessions are designed to provide a basic introduction to the use of Computer-Aided Design/Drafting (CAD) in transportation engineering, with particular regard to Civil Engineering...
The Use of Linked Spreadsheets as a Transportation Problem Solving Tool
Spreadsheet modeling is a useful tool for business as well as engineering applications. Until the advent of linked spreadsheets this type of modeling was based on the concept of preparing...
A Peak Hour High Capacity Reservation and Person-Based Functional Classification Concept for Urban Mobility Plans and Corridor Growth Management
The management of future growth and mobility in urban corridors and areas has been based in part upon use of the Levels of Service and procedures of the Highway Capacity Manual. Capacity...
A CADD Program for Simulating Turning Vehicles
The turning capability of one or more 'design' vehicles and their swept paths has a significant influence on the layout of transportation facilities such as roadway intersections, parking...
Environmental Consulting Grows Up
The environmental engineering industry got its first taste of maturity in 1992, courtesy of the weak U.S. economy. Revenue growth, which had raced along at a 25%-30% clip for years, abruptly...
Engineering: Environmental vs. Developmental Goals
The 1992 winner of the Daniel W. Mead Student Paper competition explores the potential conflict for engineers, between environmental and developmental goals. Noting a dictionary definition...
Scoping Out Scour
Bridge scour�soil erosion around piers and pilings�threatens tens of thousands of bridges across the U.S. Traditionally, engineers have mapped bridge scour by driving probes into the subbottom...
