The Impacts Of Telecommuting On The Time-Space Distribution Of Daily Activities, Mario Benito Rojas Iv Nov 2016

The Impacts Of Telecommuting On The Time-Space Distribution Of Daily Activities, Mario Benito Rojas Iv

FIU Electronic Theses and Dissertations

As major cities have aged, they have also met or exceeded their transportation infrastructure’s capacity. This has led to many negative impacts such as increased greenhouse gas emissions, delay, travel time, congestion, as well as decreased energy independence, standard of living for the cities’ inhabitants and the world as a whole. As a result, these cities will undoubtedly suffer and will struggle to meet the needs of their citizens. It is becoming more evident, and relevant, that the solution to today’s and tomorrow’s transportation problems will be overcome through the use of policy as well as innovative strategies, one of …


Sequential Decision Making For Improving Efficiency In Urban Environments, Pradeep Varakantham Jul 2016

Sequential Decision Making For Improving Efficiency In Urban Environments, Pradeep Varakantham

Research Collection School Of Computing and Information Systems

Rapid "urbanization" (more than 50% of world's population now resides in cities) coupled with the natural lack of coordination in usage of common resources (ex: bikes, ambulances, taxis, traffic personnel, attractions) has a detrimental effect on a wide variety of response (ex: waiting times, response time for emergency needs) and coverage metrics (ex: predictability of traffic/security patrols) in cities of today. Motivated by the need to improve response and coverage metrics in urban environments, my research group is focussed on building intelligent agent systems that make sequential decisions to continuously match available supply of resources to an uncertain demand for …

Recent evidence suggests that urban forms and materials can help to mediate temporal variation of microclimates and that landscape modifications can potentially reduce temperatures and increase accessibility to outdoor environments. To understand the relationship between urban form and temperature moderation, we examined the spatial and temporal variation of air temperature throughout one desert city—Doha, Qatar—by conducting vehicle traverses using highly resolved temperature and GPS data logs to determine spatial differences in summertime air temperatures. To help explain near-surface air temperatures using land cover variables, we employed three statistical approaches: Ordinary Least Squares (OLS), Regression Tree Analysis (RTA), and Random Forest …


Bioswales For Stormwater Remediation And Infiltration: Assessing Regulatory Climate And Quantifying Filtration Capacity Of A Claremont Bioswale, Skyler Lewis, Boyu Liu, Paul Picciano, Liana Solis, Char Miller May 2016

Bioswales For Stormwater Remediation And Infiltration: Assessing Regulatory Climate And Quantifying Filtration Capacity Of A Claremont Bioswale, Skyler Lewis, Boyu Liu, Paul Picciano, Liana Solis, Char Miller

Environmental Analysis Program Senior Projects

Watershed management is critical in ensuring a sustainable water supply. This project is designed to assess the impact of bioswales in the context of Southern California’s climate. The patterns of droughts and floods make these green infrastructure appealing as they offer potential to boost water quality and regenerate local aquifers, while reducing the area of impermeable surfaces in our urban landscape. As bioswales have not been commonly incorporated into infrastructure development, our project focuses on a relatively new bioswale, added in 2012 and located on Pomona College’s campus, to serve as our case study in determining the viability of bioswales …


Mining And Clustering Mobility Evolution Patterns From Social Media For Urban Informatics, Chien-Cheng Chen, Meng-Fen Chiang, Wen-Chih Peng May 2016

Mining And Clustering Mobility Evolution Patterns From Social Media For Urban Informatics, Chien-Cheng Chen, Meng-Fen Chiang, Wen-Chih Peng

Research Collection School Of Computing and Information Systems

In this paper, given a set of check-in data, we aim at discovering representative daily movement behavior of users in a city. For example, daily movement behavior on a weekday may show users moving from one to another spatial region associated with time information. Since check-in data contain both spatial and temporal information, we propose a mobility evolution pattern to capture the daily movement behavior of users in a city. Furthermore, given a set of daily mobility evolution patterns, we formulate their similarity distances and then discover representative mobility evolution patterns via the clustering process. Representative mobility evolution patterns are …

Temporal Variations Of Citizens’ Demands On Flood Damage Mitigation, Streamflow Quantity And Quality In The Korean Urban Watershed, Change-Yu Hong, Eun-Sung Chung Apr 2016

Temporal Variations Of Citizens’ Demands On Flood Damage Mitigation, Streamflow Quantity And Quality In The Korean Urban Watershed, Change-Yu Hong, Eun-Sung Chung

Sustainable watershed management (SWM) can be achieved through recognition and reflection upon the values of citizens. Collaborative governance consisting of citizens is crucial for successful SWM. Collaborative governance definitely requires an active participatory decision-making process that reflects citizens’ preferences. Citizen preference also tends to substantially change with life pattern and life quality. These shifts can be caused by slight variations in both social priorities and personal preferences for SWM. Therefore, collaborative water governance must be frequently renewed in response to citizens’ values through the participatory framework. The An’yang Stream in South Korea is generally regarded as a representative urban stream …

We analyzed the impact of amenity and biodiversity protection as mandated in national forest plans on the implementation of hazardous fuel reduction treatments aimed at protecting the wildland urban interface (WUI) and restoring fire resilient forests. We used simulation modeling to delineate areas on national forests that can potentially transmit fires to adjacent WUI. We then intersected these areas with national forest planning maps to determine where mechanical treatments are allowed for restoration and fire protection, versus areas where they are prohibited. We found that a large proportion of the national forest lands (79%) can spawn fires that burn adjacent …


Micrometeorological Simulations To Predict The Impacts Of Heat Mitigation Strategies On Pedestrian Thermal Comfort In A Los Angeles Neighborhood, Mohammad Taleghani, David J. Sailor, George A. Ban-Weiss Feb 2016

The urban heat island impacts the thermal comfort of pedestrians in cities. In this paper, the effects of four heat mitigation strategies on micrometeorology and the thermal comfort of pedestrians were simulated for a neighborhood in eastern Los Angeles County. The strategies investigated include solar reflective ‘cool roofs’, vegetative ‘green roofs’, solar reflective ‘cool pavements’, and increased streetlevel trees. Aseries of micrometeorological simulations for an extreme heat day were carried out assuming widespread adoption of each mitigation strategy. Comparing each simulation to the control simulation assuming current land cover for the neighborhood showed that additional street-trees and cool pavements reduced …


Precolonial Institutions And Deforestation In Africa, S. Larcom, Terry Van Gevelt, A. Zabala Feb 2016

Precolonial Institutions And Deforestation In Africa, S. Larcom, Terry Van Gevelt, A. Zabala

Research Collection College of Integrative Studies

We find that local institutions inherited from the precolonial era continue to play an important role in natural resource governance in Africa. Using satellite image data, we find a significant and robust relationship between deforestation and precolonial succession rules of local leaders (local chiefs). In particular, we find that those precolonial areas where local leaders were appointed by ‘social standing’ have higher rates of deforestation compared to the base case of hereditary rule and where local leaders were appointed from above (by paramount chiefs). While the transmission mechanisms behind these results are complex, we suggest that areas where local leaders …

Urban greenery is a favoured approach applied towards reducing urban warmth and climate discomfort, but ascertaining its measured and perceived effectiveness in tropical climates is relatively understudied. To this end, we investigated microclimate differences within an urban park (the Singapore Botanic Gardens) to assess if variations in plot-scale land cover affect both objective (measured) and subjective (surveyed) microclimate data. Over two monsoonal seasons, we obtained data from four distinct sites—a tropical rainforest stand, a palm tree valley, a water-body feature, and the park visitors’ centre. Measured climate data (e.g. air temperature, vapour pressure, wind velocity and globe temperatures) were used …
