Laboratory And Field Investigations To Address Erosion, Volume Change And Desiccation Cracking Of Compost Amended Expansive Subsoils
(Civil & Environmental Engineering, 2007-08-23)
Desiccations cracks are formed during drying process of fine grained cohesive soils in summer and these cracks often appear on unpaved subgrades due to direct exposure to sun. These cracks allow surface runoff infiltration ...
Runway Incursion Mitigation, Capacity Enhancement, And Safety Improvements With Perimeter Taxiway Operations at Dallas Fort Worth International Airport
(Civil & Environmental Engineering, 2007-08-23)
A perimeter taxiway (PT) or end-around taxiway (EAT) operation is a new concept being developed at several airports around the country to eliminate active departure runway incursions during peak periods. PTs will enhance ...
Stated Preference Modeling And Analysis Of Managed Lanes
(Civil & Environmental Engineering, 2007-08-23)
The thesis deals with the Managed Lanes demand estimation problem in the state of Texas. Managed Lanes are a general type of High Occupancy Toll roads, whose lane management and operational features may be dynamically ...
Regional Prioritization Of Corridors For Traffic Signal Retiming
(Civil & Environmental Engineering, 2007-08-23)
Every three to four years, the North Central Texas Council of Governments (NCTCOG) funds signal retiming projects to improve air quality in the Dallas-Fort Worth region. As sufficient funds are not available to retime all ...
The Travel Behavior Of Minority Cohorts In Texas
(Civil & Environmental Engineering, 2007-09-17)
Texas is changing dramatically; the most conservative population forecast indicates that Hispanics will account for 50% of the Texas population before 2035. Not only is the number of Hispanics on the rise in Texas, but ...
Mode Choice Models For Long Distance Travel In USA
(Civil & Environmental Engineering, 2007-08-23)
The influences of technology and economic development on human activity are increasingly taking place on larger spatial scales. As a consequence, complementary interactions between urban regions are getting stronger, which ...
Capacity Estimation Of Two-sided Type C Weaves On Freeway
(Civil & Environmental Engineering, 2007-09-17)
A weaving section is a common design on major highway facilities that has been an interest to researchers for years. Weaving areas are characterized by frequent lane changes, which significantly reduce the capacity of the ...
Discharge Headway At Signalized Intersections In Monterrey, Nuevo Leon, Mexico
(Civil & Environmental Engineering, 2007-08-23)
Driver behavior has been the subject of study for almost 100 years. As a result, driver characteristics have been determined and used in the design of highway elements, both for interrupted and for free flow facilities. ...
Effectiveness Of Signal Coordination As An Emission Reduction Measure For Vehicles
(Civil & Environmental Engineering, 2007-08-23)
Air Pollution is a significant health and environmental concern. Vehicular emissions are major contributors to many air pollution problems. There is growing interest in reducing carbon dioxide emission because of the ...
Impacts Of Signal Synchronization On Vehicular Emissions - An On-board Measurement Case Study
(Civil & Environmental Engineering, 2007-08-23)
Nearly 56% of total nitrogen oxide (NOx) emissions are produced by mobile sources. Transportation and air quality managers at the state and regional level have the responsibility of developing and evaluating Transportation ...
