Effectiveness of speed trailers on low-speed urban roadways
(Texas A&M University, 1997)
Efforts are being made to use speed management methods to match operating speeds to posted speeds and to reduce the variability in vehicle speeds. The effectiveness of many different methods of speed management has not ...
Perceptual and cognitive factors in legend legibility for large freeway guide signs
(Texas A&M University, 1997)
In the United States, older drivers are increasing in numbers on our public highways; the U.S. Census Bureau predicts the age groups of sixty-five and above will increase their percentage of the population over the next ...
Quantifying improvements in the Engineering-Procurement-Construction (EPC) process from the implementation of information management strategies within materials management
(Texas A&M University, 1997)
Throughout all industries where material flow or handling is involved, employers have implemented various information management technologies with the following goals: 1) to reduce cost, time, and effort, 2) to improve ...
The mathematical modeling of a Tuned Liquid Damper
(Texas A&M University, 1997)
The goal of this research is the simplification of the mathematical modeling process of a Tuned Liquid Damper. In an environment of increasingly flexible and lightly damped structures, the suppression of structural vibrations ...
Feasibility of the design of dual-lane ramp meters in Texas
(Texas A&M University, 1997)
As recurrent congestion and the number of vehicles on urban freeways in Texas have increased, the ability to effectively meter traffic using single-lane ramp meters has deteriorated. Other state departments of transportation ...
An analysis of the multiple paths used in traffic assignment algorithms
(Texas A&M University, 1997)
Historically, the four-step planning process has been used to estimate future roadway volumes and identify future roadway needs. Recently, the focus has shifted to the use of planning models to make system operations ...
Relationship between speed distribution measures and rural two-lane highway characteristics
(Texas A&M University, 1997)
Understanding the behavior of speed population distributions on rural two-lane highways is needed to address driver error associated with elements of the highway. Previous research has identified a direct relationship ...
Enhanced desorption of 2,4,6 Trinitrotoluene
(Texas A&M University, 1997)
Trinitrotoluene (TNT) has been the most commonly used explosive. The production process generates large quantities of waste contaminated with TNT. Most of these wastes were dumped in designated disposal sites. Over the ...
Data collection, storage and integration requirements torealistically assess State road maintenance needs
(Texas A&M University, 1997)
The Texas Department of Transportation (TXDOT) allocates maintenance funds annually to each district from the central office. The district personnel are concerned that the allocation of maintenance funds is not based on ...
