Location And Capacity Modeling Of Network Interchanges, Aldo D. Fabregas
Location And Capacity Modeling Of Network Interchanges, Aldo D. Fabregas
USF Tampa 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 …
Automatic Identification Of Points Of Interest In Global Navigation Satellite System Data: A Spatial Temporal Approach, Khoa Anh Tran
Automatic Identification Of Points Of Interest In Global Navigation Satellite System Data: A Spatial Temporal Approach, Khoa Anh Tran
USF Tampa 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 …
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
USF Tampa 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 …
Preparing For The Next Generation Of Senior Population: An Analysis Of Changes In Senior Travel Behavior Over The Last Two Decades, Joseph Nicholas Samus
Preparing For The Next Generation Of Senior Population: An Analysis Of Changes In Senior Travel Behavior Over The Last Two Decades, Joseph Nicholas Samus
USF Tampa 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 Transferability Of Activity-Based Travel Forecasting Models, Sujan Sikder
Spatial Transferability Of Activity-Based Travel Forecasting Models, Sujan Sikder
USF Tampa 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 that …
Preserving Place: A Grounded Theory Of Citizen Participation In Community-Based Planning, Pamela Jo Hatley
Preserving Place: A Grounded Theory Of Citizen Participation In Community-Based Planning, Pamela Jo Hatley
USF Tampa 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 …
