Connected Vehicle System Design For Signalized Arterials, Xianfeng Terry Yang, Mingyue Ji, Qinzheng Wang

TREC Final Reports

It can be expected that connected vehicles (CVs) systems will soon go beyond testbed and appear in real-world applications. To accommodate a large number of connected vehicles on the roads, traffic signal control systems on signalized arterials would require supports of various components such as roadside infrastructure, vehicle on-board devices, an effective communication network, and optimal control algorithms. In this project, we aim to establish a real-time and adaptive system for supporting the operations of CV-based traffic signal control functions. The proposed system will prioritize the communication needs of different types of CVs and best utilize the capacity of the …

Understanding Economic And Business Impacts Of Street Improvements For Bicycle And Mobility – A Multicity Multiapproach Exploration, Jenny H. Liu, Wei Shi

TREC Final Reports

Many cities across the country, as part of Complete Streets initiatives or to promote community livability and environmental sustainability, have engaged in street improvement or transportation infrastructure upgrade projects that increase access and mobility for pedestrians and bicyclists through a reduction of on-street parking or traffic lanes. With various transportation modes competing for scarce resources (including right-of-way and transportation funding), city planners and transportation agencies often struggle with how to justify these infrastructure investments for non-motorized modes such as bicycling and walking, particularly when driving is still the predominant mode of transportation in most cities. There is a vital need …

Game Theory Approaches For Transportation Problems, Mahdi Takalloo

USF Tampa Graduate Theses and Dissertations

This dissertation considers three separate game theory problems in transportation. In the first problem, a combinatorial auction market has been proposed for fractional ownership of autonomous vehicles. The proposed combinatorial auction has two unique features. First, the items are continuous time slots defined by bidders and second, the spatial information of bidders has been incorporated so that sharing becomes a viable plan. A conflict-based formulation of the winner determination problem has been proposed, for which an effective solution approach based on a heuristic and a maximal-clique based relaxation has been presented. The second part of the dissertation examines a pessimistic …

Ohio Workers And The Covid-19 Global Health Emergency, Joseph Andre, Robert Gleeson

All Maxine Goodman Levin School of Urban Affairs Publications

The global economy has never before experienced the scale of sudden economic shock that is now underway. This is unchartered territory. Although the U.S. has many economic policies and worker support programs designed to ease dislocation during recessions, these programs were not designed for the unique circumstances of this global pandemic.

The most important program for workers is Unemployment Insurance. The first chart in this report shows the unprecedented number of new applications for unemployment insurance filed by Ohio workers during the week of March 16th. If all applicants are awarded benefits, the second chart shows that the number of …

The Impacts Of The Bicycle Network On Bicycling Activity: A Longitudinal Multi-City Approach, Wei Shi

Dissertations and Theses

Bicycling is a promising approach to improve health, environment, and economic development of urban places. Theoretically, a bicycle network's component goes beyond lanes and paths, and would generate greater impacts than the sum of its parts. However, most previous research focused on how individual types of bicycle-related infrastructure could promote bicycling. Few empirical studies investigated how bicycle networks impact bicycling activity. This project attempts to address this question. Specifically, how to properly measure bicycle networks, and what impacts bicycle networks have on bicycling activity, e.g. bike ridership and bike mode choice, across different cities and longitudinally.

To address the first …

From Brooklyn To “Brooklyn” The Cultural Transformations Of Leisure, Pleasure, And Taste, Emily Holloway

Publications and Research

To tell the story of Brooklyn’s complex history in hospitality and cuisine is to tell a story about the tensions of high and low culture, of the mobility of capital and residents, and of the tremendous influence yielded by macroeconomic change. A sleepy bedroom community for the eighteenth and much of the early nineteenth centuries, Brooklyn’s waterfront (both historically and today) is deeply tied to its nineteenth and twentieth-century industrial heritage. The ad hoc economies that supported factory and dock workers, included boardinghouses, saloons, brothels, food carts, and amusement parks and drew a stark contrast to those of factory and …

Drones: Where Does The National Airspace System Start?, Jason T. Lorenzon J.D.

National Training Aircraft Symposium (NTAS)

Unmanned Aerial Systems (UAS), Unmanned Aeronautical Vehicles (UAV), drones and Personal Aerial Vehicles (PAV) constitute the greatest technological advancement since the jet age. (Elaine Chao, Secretary of Transportation, October 26, 2017) This technological advancement has prompted significant public policy challenges and the need for new laws regarding navigable airspace. This proposal investigates how airspace used by drones will evolve given existing Constitutional and common law principals. These principals will influence the creation, development and modification of UAS airspace regulations by the Federal Aviation Administration (FAA).

Two critical but unanswered questions concerning the National Airspace System, are where does navigable airspace …

No.08: Improving The Profitability Of Wet Market Food Vendors In China, Xinxian Qi, Taiyang Zhong, Zhenzhong Si, Xianjin Huang

Hungry Cities Partnership

■ The characteristics of individual vendors and their business operations have a more significant impact on business profits than more general socioeconomic factors. Policy interventions need to prioritize the former.

■ The profits of wet market vendors vary spatially in Nanjing, China. The average profit level in central urban districts is higher than in peri-urban districts.

■ Almost all determinants have more significant impacts on vendor profitability in peri-urban than urban areas. Measures should therefore be taken to improve the profitability of wet market vendors in peri-urban areas.

No.09: Enhancing Food Security Through Urban Agriculture In Kingston, Jamaica, Elizabeth Thomas-Hope, Robert Kinlocke, Therese Ferguson

Hungry Cities Partnership

■ Much focus has been accorded rural agriculture, both in the literature and in practice. Yet urban agriculture is both a viable and necessary area of focus as it pertains to food security in Jamaica.

■ An education and communication strategy is required to ensure that attitudes towards nutrition and poor food choices are changed (within the range of affordability) in efforts to achieve food security.

■ Given the threats posed by climate change, the development of urban agriculture should incorporate not only previously designated sites through zoning for small-scale livestock and produce rearing; it also should incorporate backyard farming/gardening, …

No.06: Gender Inequality And Food Security Policy Responses, Mary Caesar

Hungry Cities Partnership

■ Gender inequality and the legacy of racial discrimination operate alongside poverty and economic inequality to shape the household food security experience in low-income areas in South African cities.

■ In Cape Town, male-headed households are more likely to be food secure than female-headed households, although both experience high levels of severe food insecurity.

■ National food security policy and local government do not recognize the systemic nature of gender inequality and food insecurity; a gap that needs to be addressed.

Visualizing Statewide Trips: Tools To Leverage Gps Data In Transportation Planning, Nikola Markovic

TREC Project Briefs

The University of Utah has a new data visualization service to offer to state DOTs and other agencies. Using Small Starts funding from the National Institute for Transportation and Communities (NITC), researcher Nikola Markovic and his team have developed a suite of visual analysis tools to demonstrate how GPS trajectory data can help accurately model and analyze mobility trends. These data are typically purchased from vendors, which means that transportation agencies must first understand the benefits before they decide to invest in data acquisition.

The Spatial Optimization And Evaluation Of The Economic, Ecological, And Social Value Of Urban Green Space In Shenzhen, Yuhan Yu, Wenting Zhang, Peihong Fu, Wei Huang, Keke Li, Kai Cao

Research Collection School Of Computing and Information Systems

Urban green space (UGS) is important in urban systems, as it benefits economic development, ecological conservation, and living conditions. Many studies have evaluated the economic, ecological, and social value of UGS worldwide, and spatial optimization for UGS has been carried out to maximize its value. However, few studies have simultaneously examined these three values of UGS in one optimization system. To fill this gap, this study evaluated the economic value of UGS in terms of promoting housing prices, its ecological value through the relief of high land surface temperature (LST), and its social value through the provision of recreation spaces …

Traffic Congestion In F.C.T: Demand And Supply Approach, Ibrahim Abdul, Salihu Habibu Mohammed Gani, Ibrahim G. Umaru

Bullion

This study examined traffic congestion in Abuja metropolis, F.C.T.- Nigeria using demand and supply approach. The study adopted survey research design. Primary data was collected using questionnaires. Descriptive statistics was used to analysed the data with the aid of tables and graphs. It was discovered that as a road reaches its capacity, each additional vehicle imposes more total delay on others than they bear, resulting in excessive traffic volumes. Congestion is mainly due to the intensive use of automobiles, whose ownership has spread massively in the F.C.T. in recent decades. The study revealed that traffic congestion causes serious consequences in …
