Analysis of trip item non-response bias in the Houston-Galveston area council household travel surveys
(Texas A&M University, 1997)
Information obtained through the collection and analysis of origin-destination travel surveys is used to develop trip rate information for input to travel demand models. Three major sources of systematic error can exist ...
The economic impacts of highway widening projects
(Texas A&M University, 1997)
Highway widening is one alternative for increasing capacity on a particular section of roadway. Capacity is the maximum hourly rate at which vehicles can reasonably be expected to traverse a uniform section of a roadway ...
Effects of weaving on frontage road operations
(Texas A&M University, 1997)
Frontage roads parallel to freeways provide access to development adjacent to the freeway while maintaining the primary mobility function of the main lanes. Weaving occurs on frontage roads as exiting vehicles attempt to ...
Measurement and quantification of aggregate thermal coefficient of expansion
(Texas A&M University, 1997)
The coefficient of thermal expansion of concrete affects thermal related distresses in pavements. Factors affecting expansion of concrete and aggregates along with existing models are reviewed. A test method to measure the ...
Degradation of organic and inorganic contaminants by zero valent iron
(Texas A&M University, 1997)
Reduction of trichloroethylene (TCE), chromium (VI), and 2,4 dinitrotoluene (2,4-DNT) by zero valent iron and palladized iron under anaerobic conditions was investigated. Reduction experiments of the contaminants were ...
Electrical response characteristics of soil-electrolyte systems (10kHz-10MHz)
(Texas A&M University, 1997)
The electrical response characteristics of saturated soils depend on soil structure, particle orientation, effective particle size and size distribution, fluid type, fluid conductivity, volume fractions, etc. The use of ...
Phase relationship equation for moisture induced shrink and swell of soils
(Texas A&M University, 1997)
Expansive soils are the cause of significant structural damage every year. These problems result from differential volumetric changes in the soil structure. In this study, a procedure is developed for using the Phase ...
Predicting reservoir sedimentation
(Texas A&M University, 1997)
Sediments accumulate in reservoirs and significantly decrease storage capacity. Predicting sedimentation is an important consideration in the design of new reservoir projects and in the management of existing reservoirs. ...
Development of an interchange analysis software
(Texas A&M University, 1997)
The planning and selection of an appropriate interchange type for a given location requires the decision maker to analyze various criteria in order to make an appropriate selection between alternative interchange configurations. ...
Accelerated solvent extraction of petroleum contaminated sediments
(Texas A&M University, 1997)
Attempts have been made in recent years to find acceptable alternatives to classical soxhlet extraction of petroleum contaminated sediments. One such method that is very promising is accelerated solvent extraction also ...
