Pedestrian Walking Speeds At Signalized Intersections In Utah, Jordi Jordan Berrett
Pedestrian Walking Speeds At Signalized Intersections In Utah, Jordi Jordan Berrett
Theses and Dissertations
The 2009 edition of the Manual on Uniform Traffic Control Devices (MUTCD) recommends a pedestrian walking speed of 3.5 feet per second for use in the timing of pedestrian clearance intervals at signalized intersections (reduced from 4.0 feet per second in the 2003 edition). Jurisdictions across the state of Utah continue to maintain pedestrian walking speeds of 4.0 feet per second for normal intersections with guidance on engineering judgement for areas where a lower pedestrian walking speed should be considered. In 2018, it was decided that the current state guidance with regard to pedestrian walking speeds be evaluated for any …
Crash Severity Distributions For Life-Cycle Benefit-Cost Analysis Of Safety-Related Improvements On Utah Roadways, Conor Judd Seat
Crash Severity Distributions For Life-Cycle Benefit-Cost Analysis Of Safety-Related Improvements On Utah Roadways, Conor Judd Seat
Theses and Dissertations
The Utah Department of Transportation developed life-cycle benefit-cost analysis spreadsheets that allow engineers and analysts to evaluate multiple safety countermeasures. The spreadsheets have included the functionality to evaluate a roadway based on the 11 facility types from the Highway Safety Manual (HSM) with the use of crash severity distributions. The HSM suggests that local agencies develop crash severity distributions based on their local crash data. The Department of Civil and Environmental Engineering at Brigham Young University worked with the Statistics Department to develop crash severity distributions for the facility types from the HSM.The primary objective of this research was to …
Deicer Usage On Concrete And Asphalt Pavements In Utah, Chase David Thomas
Deicer Usage On Concrete And Asphalt Pavements In Utah, Chase David Thomas
Theses and Dissertations
The objectives of this research were to 1) compile winter maintenance data for the Utah Department of Transportation (UDOT) to directly compare concrete and asphalt pavements with regards to deicer usage and 2) determine if there is a statistical difference in deicer usage on concrete and asphalt pavements. To this end, three data sources were consulted for this research: Material Maintenance Quality Assurance (MMQA) database, UDOT road database, and Google Maps. The final compiled data set prepared for analysis in this research contained deicer quantities by deicer type, pavement surface areas by pavement material type, traffic, longitude, latitude, and elevation …
Evaluation Of The Applicability Of The Interactive Highway Safety Design Model To Safety Audit Of Two-Lane Rural Highways, Kaitlin Chuo
Evaluation Of The Applicability Of The Interactive Highway Safety Design Model To Safety Audit Of Two-Lane Rural Highways, Kaitlin Chuo
Theses and Dissertations
The Interactive Highway Safety Design Model (IHSDM) is a suite of software developed by the Federal Highway Administration (FHWA) for monitoring and analyzing two-lane rural highways in the United States. As IHSDM is a fairly "young" program a limited amount of research has been conducted to evaluate its practicability and reliability. To determine if IHSDM can be adopted into the engineering decision making process in Utah, a study was conducted under the supervision of the Utah Department of Transportation (UDOT) to evaluate its applicability to audit safety of two-lane rural highways in Utah. IHSDM consists of six modules: Policy Review …
A Geographic Study Of Stone Houses In Selected Utah Communities, Barry M. Roth
A Geographic Study Of Stone Houses In Selected Utah Communities, Barry M. Roth
Theses and Dissertations
This thesis will investigate the spatial location of stone houses and the areal differentiation of several characteristics of stone houses in selected communities. Some differences in cultural and historical factors and in types of building stone, quarries and quarrying techniques will be studied. The thesis will also investigate why stone houses are still in existence and things that owners, residents, and others like and dislike about them.
History Of Utah's Salt Industry 1847-1970, John L. Clark
History Of Utah's Salt Industry 1847-1970, John L. Clark
Theses and Dissertations
Utah salt makers have extracted salt from three sources, the principal of these being brine from Great Salt Lake. Other sources are saline beds in Great Salt Lake Desert and subterranean halite formations in central Utah.
This study traces the development of methods used to recover and refine salt by the industry, in general, and by specific companies. It provides brief, historical sketches of the major corporations and the economic, legal, and environmental factors affecting their growth.
Utah produces about 1 per cent of the nation's salt, exporting over half of it from the state. The major factors limiting the …
Geographical Characteristics Of Early Mormon Settlements, John Haws Baum
Geographical Characteristics Of Early Mormon Settlements, John Haws Baum
Theses and Dissertations
Considerable literature has been written about the Mormons and their settlement of the lands within the Great Basin; yet no one has produced a systematic study which analyzes the following geographical factors: What pattern of land occupancy was actually used by these early pioneers? Which physical characteristics determined the selection of a site for the Mormon village? What type of city survey pattern was instigated as towns were established along the eastern margin of the Great Basin? What was the relationship between the forts and the settlements in their lay-out patterns? As these questions were systematically analyzed new findings were …
Factors That Influenced Homesteading And Land Abandonment In San Juan County, Utah, Melvin J. Frost
Factors That Influenced Homesteading And Land Abandonment In San Juan County, Utah, Melvin J. Frost
Theses and Dissertations
Homesteading in San Juan County, Utah is for the most part, located on Sage Plain at elevations between 6,000 to 7,200 feet. Sage Plain is an undulating surface deeply dissected with canyons. The soil is relatively shallow and the predominant vegetation is pinyon, juniper, sage brush and blue-stem grass.
The 52 year mean precipitation is 15.47 inches. Since the beginning of weather records there has been a noticeable decrease in the annual precipitation. There is generally sufficient moisture to mature winter wheat. Pinto beans are also grown in the more favorable locations.
Principle factors that have influenced homesteading and land …
A Historical Study Of The Influence Of The Railroad Upon Ogden, Utah, 1868-1875, Alma W. Hansen
A Historical Study Of The Influence Of The Railroad Upon Ogden, Utah, 1868-1875, Alma W. Hansen
Theses and Dissertations
The general plan of this study is to sketch the beginning of Ogden settlement and the early history up to the beginnings of the influence of the coming of the railroad, then to follow in more detail the conditions and influences that developed as the railroad was built and the changes that followed the completion of the line.
