A Microcomputer Program for Roadway Lighting Design
LUMSIM is a knowledge-based design program that uses operator input data and design criteria to select the most economical lighting system. The initial input parameters include pavement...
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....
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:...
A Bridge Management System Module for the Selection of Rehabilitation and Replacement Projects
A procedure, developed for the state of Texas is reported, which determines an allocation budget for bridge replacement and rehabilitation projects, using multi-attribute criteria and...
A Microcomputer Aided Bridge Management System
This paper presents a microcomputer based software system suitable for a local agency which will permit a local bridge system to be systematically evaluated with the use of a bridge management...
MECHOD: A Mechanistic Overlay Design Program for Flexible Pavements
This paper presents a fully mechanistic asphalt overlay design procedure for use on microcomputers. The procedure is based on fundamental characteristics of pavement layer properties and...
A Microcomputer Based Pavement Design Program
This paper describes a newly developed pavement design program. The performance of a number of pavement structures are projected over the analysis period. Structurally adequate designs...
Interfacing Pavement Management and Design Process
Pavement management systems coordinate all the activities required to provide pavements for the traveling public in a cost efficient manner. Information for the pavement management system...
Resistance Coefficient in a Tidal Channel
In applying a numerical hydrodynamic model to the tidal channel-lagoon complex around Great Sound, New Jersey, it became apparent that the model guidelines for the resistance coefficient...
Technical Work on Flexible Pipe/Soil Interaction Overview?1990
Research in the laboratory and field have been ongoing for the past seventy years on flexible pipe/soil interaction. Virtually all of the early work was done on steel pipe. During the...
Pipeline Design and Installation
The proceedings of the International Conference on Pipeline Design and Installation, held on March 25-27, 1990 in Las Vegas, Nevada, presents information on all aspects of pipeline design...
Florida Bridges Beat the Clock
Today, when budget overruns and delays on construction projects are the rule more than the exception, 11 precast segmental balanced cantilever bridges on two contracts were recently completed...
On the Drawing Board
Reliable and quantitative nondestructive evaluation (NDE) methods for construction materials of wood, concrete, masonry and structural steel are needed. NSF program director John Scalzi...
Bridges Under Surveillance
Although bridge monitoring is still in its infancy, research, pilot studies and field work are underway across the country. While today it's still a pie-in-the-sky goal, the...
Northumberland Strait Crossing Project?A Public-Private Venture
This major project has challenged the Canadian Government to produce innovative requirements in environmental planning, financing and security, and facility performance. It requires a...
Translating Bridge Tolls to a New Bridge: The Third Dartford River Crossing
In March 1986, the Department of Transport of the United Kingdom Government published Guidelines inviting promoters for the submission of private sector bids for the design, construction...
Development and Implementation of the Wekiva River Basin Regulatory Program in Central Florida
The St. Johns River Water Management District developed a comprehensive surface water management program for the basin. Between 1987 and 1989 the District implemented basin specific design...
Sprinkler System Design for Frost Protection
Both undertree and overtree systems for frost protection by sprinkling are currently being used. The criteria based on experimental results and theoretical modeling have been reviewed...
A Modern Approach to the Design of Grassed Channels
The design of grassed channels can be based on modern fluid mechanics principles. The resistance to flow in a grassed channel is linked directly to the relative roughness of the flow through...
Effect of Water Depth and Groundwater Table on Infiltration from Recharge Basins
The actual effect of water depth on infiltration depends on the depth to groundwater and on whether the wetted perimeter of the basin is clean or covered by a clogging layer of fine particles...
