The Relationship Between Separated Bicycle Lanes And Bicycle Crashes In Denver, Colorado., Wonsun Chang Dec 2019

The Relationship Between Separated Bicycle Lanes And Bicycle Crashes In Denver, Colorado., Wonsun Chang

Community and Regional Planning Program: Theses and Student Projects

Cyclists feel more comfortable when they ride in a bike facility separated from traffic. Therefore, cyclists tend to prefer separated bicycle lanes over other lanes. It follows that cities are increasing the installation of separated bicycle lanes for bicycle utilization and bicycle safety. However, previous research has proven that separated bicycle lanes cause more crashes. Through empirical study, this paper examined the impact of both separated bicycle facilities and shared roads on bicycle crashes and which is safer or dangerous among methods of the separation. This study deals with bicycle accidents in Denver from 2013 to 2019. This research creates …

Long-Term Changes Of Open-Surface Water Bodies In The Yangtze River Basin Based On The Google Earth Engine Cloud Platform, Yue Deng, Wei-Guo Jiang, Zhenghong Tang, Ziyan Ling, Zhifeng Wu Sep 2019

Long-Term Changes Of Open-Surface Water Bodies In The Yangtze River Basin Based On The Google Earth Engine Cloud Platform, Yue Deng, Wei-Guo Jiang, Zhenghong Tang, Ziyan Ling, Zhifeng Wu

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

The spatiotemporal changes of open-surface water bodies in the Yangtze River Basin (YRB) have profound influences on sustainable economic development, and are also closely relevant to water scarcity in China. However, long-term changes of open-surface water bodies in the YRB have remained poorly characterized. Taking advantage of the Google Earth Engine (GEE) cloud platform, this study processed 75,593 scenes of Landsat images to investigate the long-term changes of open-surface water bodies in the YRB from 1984 to 2018. In this study, we adopted the percentile-based image composite method to collect training samples and proposed a multiple index water detection rule …

Digitally-Mediated Practices Of Geospatial Archaeological Data: Transformation, Integration, & Interpretation, Heather Richards-Rissetto, Kristin Landau Aug 2019

Digitally-Mediated Practices Of Geospatial Archaeological Data: Transformation, Integration, & Interpretation, Heather Richards-Rissetto, Kristin Landau

Department of Anthropology: Faculty Publications

Digitally-mediated practices of archaeological data require reflexive thinking about where archaeology stands as a discipline in regard to the ‘digital,’ and where we want to go. To move toward this goal, we advocate a historical approach that emphasizes contextual source-side criticism and data intimacy—scrutinizing maps and 3D data as we do artifacts by analyzing position, form, material and context of analog and digital sources. Applying this approach, we reflect on what we have learned from processes of digitally-mediated data. We ask: What can we learn as we convert analog data to digital data? And, how does digital data transformation impact …

Generative Suburban Frameworks: Emerging Architect-Guided Optimization Workflows Within Suburban Mass Production, Chris Reeh May 2019

Generative Suburban Frameworks: Emerging Architect-Guided Optimization Workflows Within Suburban Mass Production, Chris Reeh

Masters in Architecture Program: Theses

The mass production of single-family housing has led to a number of overlooked design problems, including enormous physical footprints, subpar construction, and hastily installed infrastructure (Florida 2017). The continued growth of this development strategy has decreased the disparity of the building type, which also undergoes far less design consideration than other building typologies. Solutions to these issues have been oriented around concepts of modular construction and prefabricated elements. These ideas have typically remained in conceptual design stages, and when actualized they tend to lack the simplicity, speed, or cost of current residential construction practices. Additionally, several of these approaches could …

Combating Zombie Subdivisions In Teton Valley, Idaho, Taylor Cook May 2019

Combating Zombie Subdivisions In Teton Valley, Idaho, Taylor Cook

Community and Regional Planning Program: Theses and Student Projects

This research examined the history, background, and viable solutions to deal with zombie subdivisions in the Teton Valley area (Teton County, Idaho). Overdevelopment, lack of responsible zoning code enforcement and the 2008 economic recession are just some of the key factors that contributed to the ongoing dilemma of zombie subdivisions in the Teton Valley. The current and past long-range plan for Teton County, Idaho was reviewed and analyzed to understand the workings and planning mechanisms that were and are currently set in place. Zoning code, Idaho state statutes and development agreements between Teton County officials and developers, were closely reviewed …

(Mis)Communicating With Geographic Information System Mapping: Part 1--Choosing Units Of Representation, Rodrigo Cantarero, Maria Deguzman, Sarah Taylor, Soo-Young Hong, Jeong-Kyun Choi Apr 2019

(Mis)Communicating With Geographic Information System Mapping: Part 1--Choosing Units Of Representation, Rodrigo Cantarero, Maria Deguzman, Sarah Taylor, Soo-Young Hong, Jeong-Kyun Choi

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Extension professionals are increasingly using geographic information system (GIS) technology to develop and inform programs and services. In this article, we use a mapping exercise to demonstrate how the unit of data can be applied and inadvertently misrepresented in GIS mapping. We contrast the use of counts, percentages, and location quotients with the same data and the resulting divergence in maps. The discussion addresses ideal circumstances for using each unit of data. Overall, the article illustrates the need for Extension professionals to be cognizant of the benefits and limitations of various units of data to avoid miscommunication when using GIS …

Detection Of Linkage Between Solar And Lunar Cycles And Runoff Of The World's Large Rivers, Zhijun Dai, Jinzhou Du, Zhenghong Tang, Suying Ou, Samuel Brody, Xuefei Mei, Jietai Jing, Shoubing Yu Apr 2019

Detection Of Linkage Between Solar And Lunar Cycles And Runoff Of The World's Large Rivers, Zhijun Dai, Jinzhou Du, Zhenghong Tang, Suying Ou, Samuel Brody, Xuefei Mei, Jietai Jing, Shoubing Yu

It is an ongoing concern that global hydrological cycle can be likely intensified under context of climate change and anthropogenic actions. Here, our results show that the solar and lunar periodic motions (SLPMs) have substantial impact on the runoff of the world's large rivers. We estimate that SLPMs can produce a change of the world's large rivers runoff by as much as 6.7%. Although climate models suggest that the increased frequency of extreme events is attributed to anthropogenic activities, it is out of our expectation that as much as 73% and 85% of the extreme flood and drought events (based …

The increasing use of geographic information system (GIS) technology in various fields suggests the need for professionals, including those in Extension, to be mindful of communicating data accurately and effectively. This article examines approaches to creating classes or groupings within data as well as the weaknesses of each approach. Data break units discussed in the article include equal intervals, quantiles, and units resulting from natural breaks. Ideal situations for each type of data break are presented. The article emphasizes the need for Extension professionals to consider the effects of data grouping to avoid miscommunication when using GIS mapping.
