Understanding The Linkages Between Urban Transportation Design And Population Exposure To Traffic-Related Air Pollution: Application Of An Integrated Transportation And Air Pollution Modeling Framework To Tampa, Fl, Sashikanth Gurram
USF Tampa Graduate Theses and Dissertations
Rapid and unplanned urbanization has ushered in a variety of public health challenges, including exposure to traffic pollution and greater dependence on automobiles. Moreover, vulnerable population groups often bear the brunt of negative outcomes and are subject to disproportionate exposure and health effects. This makes it imperative for urban transportation engineers, land use planners, and public health professionals to work synergistically to understand both the relationship between urban design and population exposure to traffic pollution, and its social distribution. Researchers have started to pay close attention to this connection, mainly by conducting observational studies on the relationship between transportation, urban …
Improving Service Level Of Free-Floating Bike Sharing Systems, Aritra Pal
Improving Service Level Of Free-Floating Bike Sharing Systems, Aritra Pal
USF Tampa Graduate Theses and Dissertations
Bike Sharing is a sustainable mode of urban mobility, not only for regular commuters but also for casual users and tourists. Free-floating bike sharing (FFBS) is an innovative bike sharing model, which saves on start-up cost, prevents bike theft, and offers significant opportunities for smart management by tracking bikes in real-time with built-in GPS. Efficient management of a FFBS requires: 1) analyzing its mobility patterns and spatio-temporal imbalance of supply and demand of bikes, 2) developing strategies to mitigate such imbalances, and 3) understanding the causes of a bike getting damaged and developing strategies to minimize them. All of these …
Comprehensive Exploratory Analysis Of Truck Route Choice Diversity In Florida, Trang D. Luong
Comprehensive Exploratory Analysis Of Truck Route Choice Diversity In Florida, Trang D. Luong
USF Tampa Graduate Theses and Dissertations
This thesis presents a comprehensive exploratory analysis of truck route choice diversity in the state of Florida, for both long-haul and short-haul truck travel segments. We employ six metrics to measure three different dimensions of diversity in truck route choice between any given origin-destination (OD) pair. These dimensions are: (1) number of distinct routes used to travel between the OD pair, (2) the extent of overlap (or lack thereof) among the routes, and (3) the evenness (or the dominance) of the usage of different unique routes. The diversity metrics were utilized to examine truck route choice diversity from over 73,000 …
How Transportation Network Companies Could Replace Public Transportation In The United States, Matthew L. Kessler
How Transportation Network Companies Could Replace Public Transportation In The United States, Matthew L. Kessler
USF Tampa Graduate Theses and Dissertations
The quantity of cell phone applications or mobile apps have seen an upsurge at an exponential rate in under a decade. Many have been created for a variety of industries, including transportation. The advent and subsequent commercialized implementation of near-instant transport by a middleman-type of app is now known as a Transportation Network Company or TNC. Examples of the more renowned TNCs are Uber, Lyft and Sidecar.
In recent years, TNCs have cultivated a tremendous following, to the degree of taxicab desertion. Moreover, the massive success of TNCs led to expansion of its capacities into public transportation.
The TNC’s expeditious …

Suburban Sustainability
As the United States and other nations strive to cope with the obesity epidemic (NCHS, 2015), progressive communities are developing sidewalk infrastructure to promote physical activity and health. The Center for Disease Control (CDC) recommends that community-based interventions like neighborhood walk, bike programs etc. have shown to be effective in promoting physical activity and health. Smart cities are embracing the development of community trails and promoting their use to increase physical activity among youth and adults. System implementation, data collection, and analysis were performed from January 2015 through July 2015. To promote these objectives, communities and cities need accurate information …
Autonomous Vehicles: An Empirical Assessment Of Consumers’ Perceptions, Intended Adoption, And Impacts On Household Vehicle Ownership, Nikhil Menon
USF Tampa Graduate Theses and Dissertations
Emerging automotive and transportation technologies have provided revolutionary possibilities in the way we might travel in the future. Major car manufacturers and technology giants have demonstrated significant progress in advancing and testing autonomous vehicles in real-life traffic conditions. Governmental agencies are grappling with how to plan transportation systems for a world with autonomous vehicles. Past research has shown that not all technologies are immediately welcomed by the public. Autonomous Vehicles would have to likely go through a similar phase, and would need to overcome not just technological challenges but also social barriers for successful penetration into the marketplace. Most previous …
Reappropriating Public Space In Nanchang, China: A Study Of Informal Street Vendors, Bryan C. Winter
Reappropriating Public Space In Nanchang, China: A Study Of Informal Street Vendors, Bryan C. Winter
USF Tampa Graduate Theses and Dissertations
Since China's shift to market socialism, many marginalized by this process work as informal street vendors where they reappropriate public space in order to survive―a practice at odds with urban authorities' modernizing agenda. In relation to these competing logics concerning public space's use value versus its exchange value, this dissertation examines the practices, experiences, and agency of informal street vendors working in Sanjingwuwei, an ordinary, yet rapidly gentrifying, neighborhood of Nanchang, capital and largest city of southeastern China's Jiangxi Province. After describing the growth of an informal economy in modern China and providing a history of street vending, I describe …
Space-Time Transportation System Modelling: From Traveler’S Characteristics To The Network Design Problem, Mohsen Parsafard
Space-Time Transportation System Modelling: From Traveler’S Characteristics To The Network Design Problem, Mohsen Parsafard
USF Tampa Graduate Theses and Dissertations
Traditional network design problems only consider the long-term stationary travel patterns (e.g., fixed OD demand) and short-term variations of human mobility are ignored. This study aims to integrate human mobility characteristics and travel patterns into network design problems using a space-time network structure. Emerging technologies such as location-based social network platforms provide a unique opportunity for understanding human mobility patterns that can lead to advanced modeling techniques. To reach our goal, at first multimodal network design problems are investigated by considering safety and flow interactions between different modes of transport. We develop a network reconstruction method to expand a single-modal …
Impacts Of New Light Rail Transit Service On Riders' Residential Relocation Decisions, You-Lian Chu, Yi Deng, Rongfang (Rachel) Liu
Impacts Of New Light Rail Transit Service On Riders' Residential Relocation Decisions, You-Lian Chu, Yi Deng, Rongfang (Rachel) Liu
Journal of Public Transportation
Using the rider survey data collected from Hudson-Bergen Light Rail Transit System in New Jersey, this paper investigated the residential relocating decisions of the riders who have been riding the LRT for a period of time. Using the Heckman’s sample selection model, the paper extends the current mobility literature by describing not only a rider’s likelihood to move as a result of the new LRT service but also the movers’ orientation toward their residence distances to LRT stations. Information on the socio-economic characteristics of the movers and their residence distances to LRT stations would help planners and developers identify areas …
The S-Curve Of Technological Adoption: Mobile Communication Devices On Commuter Trains In The Chicago Region, 2010–2015, Joseph P. Schwieterman, Lauren A. Fischer
The S-Curve Of Technological Adoption: Mobile Communication Devices On Commuter Trains In The Chicago Region, 2010–2015, Joseph P. Schwieterman, Lauren A. Fischer
Journal of Public Transportation
Urban transit riders’ use of mobile communication devices has grown markedly in recent years. Studies evaluating the usage of these devices have generally focused on only one or two points in time, limiting their ability to describe long-range trends. To foster insights into this issue, this study evaluated data from 15,531 passenger observations collected on 156 commuter trains on the metropolitan commuter rail system of Chicago, Illinois, from 2010 through 2015. The data show that the rate of technological usage is following an S-shaped pattern among passengers. The share of passengers using mobile communication devices at observed points grew sharpest …
Access To Taxicabs For Unbanked Households: An Exploratory Analysis In New York City, David A. King, Juan Francisco Saldarriaga
Access To Taxicabs For Unbanked Households: An Exploratory Analysis In New York City, David A. King, Juan Francisco Saldarriaga
Journal of Public Transportation
Taxicabs are critical complements to public transit systems. In New York City, ubiquitous yellow cabs are as iconic as the city’s subway system, and the city recently added green taxicabs to improve taxi service in areas outside of the Central Business Districts and airports. In this paper, we used multiple datasets to explore taxicab fare payments by neighborhood and examine how paid taxicab fares are associated with use of conventional banking services. There are clear spatial dimensions of the propensity of riders to pay cash, and we found that both immigrant status and being “unbanked” are strong predictors of cash …
A New Market Segmentation Approach: Evidence From Two Canadian Cities, Dea Van Lierop, Ahmed El-Geneidy
A New Market Segmentation Approach: Evidence From Two Canadian Cities, Dea Van Lierop, Ahmed El-Geneidy
Journal of Public Transportation
Traditionally, transit market research has categorized passengers into two distinct groups: captive riders and choice riders. Market analyses that depend on such broad categories are likely to overlook important details about the needs and desires of their customer base. This study attempts to better understand the complexities of the different groups who take transit by using information from five years of customer satisfaction questionnaires collected by two Canadian transit providers. Employing a series of clustering techniques, the analysis reveals that nine market segments are present across different modes in both transit agencies. Three different overarching groups of transit users are …
The Causal Effect Of Bus Rapid Transit On Changes In Transit Ridership, Orion T. Stewart, Anne Vernez Moudon, Brian E. Saelens
The Causal Effect Of Bus Rapid Transit On Changes In Transit Ridership, Orion T. Stewart, Anne Vernez Moudon, Brian E. Saelens
Journal of Public Transportation
Numerous studies have reported ridership increases along routes when Bus rapid transit (BRT) replaces conventional bus service, but these increases could be due simply to broader temporal trends in transit ridership. To address this limitation, we compared changes in ridership among routes where BRT was implemented to routes where BRT was planned or already existed in King County, Washington. Ridership was measured at 2010, 2013, and 2014. Ridership increased by 35% along routes where BRT was implemented from 2010 to 2013 compared to routes that maintained conventional bus service. Ridership increased by 29% along routes where BRT was implemented from …
Measuring The Accuracy Of Bus Rapid Transit Forecasts, John Perry
Measuring The Accuracy Of Bus Rapid Transit Forecasts, John Perry
Journal of Public Transportation
The research of Dr. Bent Flyvbjerg in the 1990s and early 2000s showed that urban rail projects often cost more than estimated and carried fewer riders than projected, a troubling trend suggesting that the forecasts for urban rail projects were too optimistic in terms of cost and ridership. Inspired by that research, this analysis seeks to extend that framework to analyze Bus Rapid Transit (BRT). A study of forecast vs. actual costs and ridership was conducted for 19 BRT projects in the United States. From this, it was found that the cost projections for these projects tended to be quite …
