A Comprehensive Method for Capacity Analysis and Signal Timing Design
This paper presents a rational methodology which combines several of the most significant programs in the signalized intersection and traffic signal timing design are in a comprehensive...

A Microcomputer Package for Interrelating the Highway Capacity Manual and SOAP 84
There is some evidence that the SOAP program may replicate signalized intersection delay more realistically than the 1985 Highway Capacity Manual (HCM) operational procedure for signalized...

A Practical Way of Using the 1985 HCM - Signalized Intersection Methods
The signalized intersection chapter of the 1985 Highway Capacity Manual (HCM) is probably the most widely used chapter, and thereby the most significant, and yet is very complex and sometimes...

An Expert System for the Motivation of Traffic Signals
A case study is presented describing the initiation and development of a prototype knowledge-based system for the motivation of traffic signal control, to be applied within a user-sensitive...

SIGNALEXPERT: An Expert Syste, for Signalized Intersection Analysis and Design
This paper presents a prototype expert system, (SIGNALEXPERT), for signalized intersection analysis and design. The SIGNALEXPERT consists of four modules. The first module determines if...

The Integrated Traffic Data System
Integrated Traffic Data System (ITDS) is a microcomputer-based system designed to allow traffic engineers to store, maintain and update traffic network information in a centralized data...

Traffic Simulation at Unsignalized Intersections Using GPSS
This paper develops a simulation model, based on actual field data, that simulates the minor street left turn movement at a STOP-controlled T-intersection. This simulation model predicts...

Model for Intersection Control Analysis (MICA)
This paper describes the Model for Intersection Control Analysis (MICA). The Intersection Control Analysis is a comprehensive investigation that compares the collected data to the signal...

Using Lap Tops as Connections to Minicomputers in the City of Portland
Over the past few years, the City of Portland has used a mix of personal computers and minicomputers to accomplish its mission. This paper describes four applications of using lap top...

Problem Identification Phase in Transportation System Management
This paper describes a diagnostic management tool - procedure PITS (Problem Identification in Transportation Systems) which classifies and priorities groups of the deficiencies, thus facilitating...

DELVACS: A Computer Program for Performance Evaluation of Low Volume Coordinated Semi-Actuated Systems
This paper presents a computer program which provides a tool for making choices between coordinated and free operation on an arterial roadway under semi-actuated control. The decision...

Traffic Simulation and its Graphic Presentations
A computer simulation program for traffic signal timing design was developed. The program can provide some appealing graphic presentations not only of input data but also of output results....

Microcomputer Model for Estimating LOS on Urban and Suburban Arterials
In the 1985 Highway Capacity Manual (HCM) [1], level of service (LOS) designation for urban and suburban arterials is predicted on the average travel speed by section and for the entire...

Computer Aided Design of Traffic Signal Systems
Computer Aided Design and Drafting (CADD) has traditionally been the domain of powerful and expensive computers. Personal computer technology, however, is rapidly changing this trend by:...

Microcomputer Based Traffic Signal Inventory Records
This paper describes microcomputer software used by District 12 of the Texas State Department of Highways and Public Transportation to provide for a constantly updated inventory of traffic...

A Matching Algorithm That Eliminates the Need for Radio Signposts in Automatic Passenger Counters on Buses
Volumes of raw data collected using the Automatic Data Aquisition system are useless until they can be processed and transformed into meaningful reports and plots. This is done using a...

Sounding Out Buried Waste
Geophysical diffraction tomography (GDT) is a new remote sensing technique for quantitative high-resolution subsurface imaging. It is similar to optical holography where long wavelength...

Fish Bypass Facilities - Tehama-Colusa Canal
Operation of the canal headworks has proven to be detrimental to migrating fish passing the Red Bluff Diversion Dam. Studies performed for the U.S. Bureau of Reclamation were undertaken...

Research Needs in Movement of Agricultural Chemicals to Groundwater
Better prediction of the movement of agricultural chemicals to groundwater is necessary to permit development of best management practices to reduce adverse environmental effects of agriculture....
