Location And Capacity Modeling Of Network Interchanges, Aldo D. Fabregas Feb 2013

Location And Capacity Modeling Of Network Interchanges, Aldo D. Fabregas

Graduate Theses and Dissertations

Network design decisions, especially those pertaining to urban infrastructure, are made by a central authority or network leader, and taking into consideration the network users or followers. These network decision problems are formulated as non-linear bi-level programming problems. In this work, a continuous network design problem (CNDP) and discrete network design problem (DNDP) bi-level optimization programs are proposed and solved in the context of transportation planning. The solution strategy involved reformulation and linearization as a single-level program by introducing the optimality conditions of the lower level problem into the upper level problem. For the CNDP, an alternative linearization algorithm (modified ...


Spatial Transferability Of Activity-Based Travel Forecasting Models, Sujan Sikder Jan 2013

Spatial Transferability Of Activity-Based Travel Forecasting Models, Sujan Sikder

Graduate Theses and Dissertations

Spatial transferability of travel forecasting models, or the ability to transfer models from one geographical region to another, can potentially help in significant cost and time savings for regions that cannot invest in extensive data-collection and model-development procedures. This issue is particularly important in the context of tour-based/activity-based models whose development typically involves significant data inputs, skilled staff, and long production times. However, most literature on model transferability has been in the context of traditionally used trip-based models, particularly for linear regression-based trip generation and logit-based mode choice models, with little evidence on the transferability of activity-based models and ...


A Case Study On The Food Retail Environment Of Accra, Ghana, Shelley Jayne Oltmans Jan 2013

A Case Study On The Food Retail Environment Of Accra, Ghana, Shelley Jayne Oltmans

Graduate Theses and Dissertations

The increased presence of modern/Western style food retail outlets is changing the food retail environment in many developing countries. This phenomenon, known as "supermarketization," is just recently taking off in Sub-Saharan Africa. Through a case study methodology, this research uses direct observation, retailer interviews, mapping, a food retail assessment and household surveys, first to describe the food retail environment of consumers in the neighborhood of Ashongman Estates, located in Accra, Ghana. Second, the study evaluates consumer access to food and consumer behavior related to retail outlets and food types. Results demonstrate that, although supermarkets have entered the food retail ...


Green Roof Biodiversity In Design: Influence Of Local And Contextual Attributes On Bird Usage, Henry Narigon Jan 2013

Green Roof Biodiversity In Design: Influence Of Local And Contextual Attributes On Bird Usage, Henry Narigon

Graduate Theses and Dissertations

This purpose of this research is to identify how species of birds use urban green roofs in Iowa with the intent to eventually develop a set of guidelines for optimizing habitat on green roofs. Ten green roofs were observed for bird usage five times each between May to August, 2013 for a total of fifty observations. Birds were identified by species and their behavior was recorded during the duration of the observations. Data shows that birds use green roofs for a number of uses including foraging and gathering nest material. Bird diversity data was then compared with both green roof ...


Time To Grow Up: The Rise And Fall Of Spring Break In Fort Lauderdale, James Joseph Schiltz Jan 2013

Time To Grow Up: The Rise And Fall Of Spring Break In Fort Lauderdale, James Joseph Schiltz

Graduate Theses and Dissertations

While the 1960 release of Where the Boys Are truly institutionalized spring break as a rite of passage among American youth, the film also established Fort Lauderdale as a mecca for these collegiate pilgrimages. For the next quarter century, Fort Lauderdale was the unquestioned spring break capital of the United States. As students annually invaded their city thereafter, local residents developed a reluctant symbiotic relationship with the tradition. Although spring break was instrumental in fostering Fort Lauderdale's incredible postwar growth and carving the city's niche in Florida's emerging tourism industry, many citizens over the years grew concerned ...


Gender In The Modernist City: Shaping Power Relations And National Identity With The Construction Of Brasilia, Larissa Pires Jan 2013

Gender In The Modernist City: Shaping Power Relations And National Identity With The Construction Of Brasilia, Larissa Pires

Graduate Theses and Dissertations

This study explores the period from 1956 to 1960, when Brazil officially relocated its political center from Rio de Janeiro to Brasilia. It examines the complex process of defining national identity for Brazilian citizens in a frontier city, within the framework of conflicting racial, social, and gender roles and expectations. Methodologically, this work is based on an extensive research of Brasilia's public records, newspapers, and oral-history interviews with some of the men and women who lived and worked in Brasilia. Most of the primary sources used are found in Brasilia's Public Archives.

Building on existing scholarship, this work ...


Automatic Identification Of Points Of Interest In Global Navigation Satellite System Data: A Spatial Temporal Approach, Khoa Anh Tran Jan 2013

Automatic Identification Of Points Of Interest In Global Navigation Satellite System Data: A Spatial Temporal Approach, Khoa Anh Tran

Graduate Theses and Dissertations

In addition to the emergence of smartphones and tablets in recent years, the rise of Global Navigation Satellite Systems (GNSS) has allowed mobile tracking applications to become popular and be put into many uses. Analyzing tracking records to identify points of interest (POIs) is useful for both prediction applications and research such as human behavior analysis, transportation planning, and especially travel surveys. Past research in travel surveys has shown that a GPS mobile phone-based survey is a useful tool for collecting information about individuals. Moreover, a passive travel survey collection is preferred to an active travel survey method by the ...


Preparing For The Next Generation Of Senior Population: An Analysis Of Changes In Senior Travel Behavior Over The Last Two Decades, Joseph Nicholas Samus Jan 2013

Preparing For The Next Generation Of Senior Population: An Analysis Of Changes In Senior Travel Behavior Over The Last Two Decades, Joseph Nicholas Samus

Graduate Theses and Dissertations

Over the past several decades, the senior age group has become the fastest growing segment of the population in the United States (Warner, 2011). This study seeks to contribute to the ongoing discussion of the impacts that the increases in senior travel will have on the future transportation systems and planning efforts. The main objective of this research is to conduct an explorative analysis of the changes in senior travel behavior over the past two decades and discuss the implications of these changes to transportation planning in the future. This thesis seeks to further understanding of this topic by providing ...


Spatial Distribution Of Nitrogen Oxides, Benzene, Toluene, Ethylbenzene, And Xylenes In Hillsborough County, Florida: An Investigation Of Impacts Of Urban Forests On Ambient Concentrations Of Air Pollutants Associated With Traffic, Jill Sears Jan 2013

Spatial Distribution Of Nitrogen Oxides, Benzene, Toluene, Ethylbenzene, And Xylenes In Hillsborough County, Florida: An Investigation Of Impacts Of Urban Forests On Ambient Concentrations Of Air Pollutants Associated With Traffic, Jill Sears

Graduate Theses and Dissertations

Urban air pollution is responsible for high levels of morbidity and mortality in exposed populations due to its effects on cardiovascular and respiratory function. Transportation-related air pollutants account for the majority of harmful air pollution in urban areas. Forests are known to reduce air pollution through their ability to facilitate dry deposition and atmospheric gas exchange. This work characterizes the interactions between transportation air pollutants and urban forests in Hillsborough County, Florida. A highly spatially resolved passive air sampling campaign was conducted to characterize local concentrations of nitrogen oxides, benzene, toluene, ethylbenzene, and xylenes (BTEX) in Hillsborough County, Florida. Sampling ...


Preserving Place: A Grounded Theory Of Citizen Participation In Community-Based Planning, Pamela Jo Hatley Jan 2013

Preserving Place: A Grounded Theory Of Citizen Participation In Community-Based Planning, Pamela Jo Hatley

Graduate Theses and Dissertations

For this research project I used grounded theory methodology and qualitative research methods to examine how and why citizens participated in local community-based planning and land development entitlement processes, and learn about their experiences participating in those processes. I conceptualized the citizens' main concern as preserving the character of the place they consider their community. This research demonstrates that citizens participate in community-based planning and land development entitlement processes out of a concern for preserving the character of their communities. They define the character of their communities in terms of their geographic boundaries, history, traditions, people, lifestyle, and qualitative features ...
