Chicago Recovery Partnership Evaluation of the American Recovery and Reinvestment Act

From 2009-2011, the City of Chicago and Cook County received a total of $2.35 billion in funding provided by the American Recovery and Reinvestment Act [ARRA]. The stimulus money was allocated to seven areas: education, basic needs, transportation and infrastructure, housing and energy, public safety, broadband and workforce development. The Chicago Recovery Partnership Evaluation of ARRA analyzes the impact of the stimulus spending using a costbenefit analysis framework. This report evaluated$1.09 billion of total spending in Chicago and Cook County, resulting in net benefits ranging from -$173.9 to$2,740.2 million. The wide range in net benefits is attributed largely to education, which received over half of ARRA funding

Analysis of urban expansion and transportation characteristics

Urban expansion and transportation are actually interrelated. Shanghai’s rapid urban expansion was caused by the inflow of people and the relocation of employment, which increased people’s travel demand, particularly for long-distance and motorized travel, greatly from 1990s onward. Dynamic travel purposes increased non-commute trips as well as people’s travel rates. Thus, average daily trips rose sharply due to these combined effects. Based on results of statistical analyses, population and GDP are statistically significant factors that increase average daily trips, while the expansion of urban space is significantly related to the growth of private motorized car share in Shanghai. People are working to increase transportation supply to fulfill travel demand by constructing more roads and promoting a well-designed public transportation system. However, the growth in demand has outpaced the increase in supply, as indicated by more congested roads, trains, and buses despite the significant increase in subway ridership. The demand management strategy needs to be involved in the policy making process to manage not only the growth of motorization, but also the growth of urban spaces and population. More supply still induces new demand, and the demand will continue to grow unless it is managed

focusing on the case of Korea's abnormal precipitation in the summer of 2020

Thesis(Master) -- KDI School: Master of Public Management, 2022Climate change and urbanization are accelerating the seriousness of urban flooding. Urban flooding is caused by a combination of urban characteristics, drainage systems, and land-use status. Preventive measures are important in terms of the fact that disasters in urban areas cause enormous human and property damages, and that the cost of restoration exceeds the amount of damage. This paper aims to contribute to improving city’s responsiveness to urban floods by investigating major causes of and suggesting improvement measures to urban flooding. It discusses a framework that highlights the three stages of disaster management (i.e., pre-, during, and post-disaster), including each stage’s main activities required and the importance of feedback systems across the stages. Using this framework, a case of urban flooding that took place in the summer of 2020 in Korea, which was recorded the longest rainy season in the country, was analyzed. Through the analysis, two main problems were identified: First, the capacity of urban flood defense facilities may be fundamentally insufficient due to abnormal precipitation exceeding expectations. Each time a rainfall record is updated, a flexible design standard should be prepared that comprehensively considers the climate, topography, and land-use status rather than unconditionally raising the design standard. Second, the response system to urban floods that occur repeatedly every year is unsatisfactory. Starting with the linkage of information distributed among each institution, the information system should be used as a means, not a purpose.1. Introduction 2.

Managing ubiquitous eco cities: the role of urban telecommunication infrastructure networks and convergence technologies

A successful urban management system for a Ubiquitous Eco City requires an integrated approach. This integration includes bringing together economic, socio-cultural and urban development with a well orchestrated, transparent and open decision making mechanism and necessary infrastructure and technologies. Rapidly developing information and telecommunication technologies and their platforms in the late 20th Century improves urban management and enhances the quality of life and place. Telecommunication technologies provide an important base for monitoring and managing activities over wired, wireless or fibre-optic networks. Particularly technology convergence creates new ways in which the information and telecommunication technologies are used. The 21st Century is an era where information has converged, in which people are able to access a variety of services, including internet and location based services, through multi-functional devices such as mobile phones and provides opportunities in the management of Ubiquitous Eco Cities. This paper discusses the recent developments in telecommunication networks and trends in convergence technologies and their implications on the management of Ubiquitous Eco Cities and how this technological shift is likely to be beneficial in improving the quality of life and place. The paper also introduces recent approaches on urban management systems, such as intelligent urban management systems, that are suitable for Ubiquitous Eco Cities

The Burden of Choice, the Complexity of the World and Its Reduction: The Game of Go/Weiqi as a Practice of "Empirical Metaphysics

The main aim of the text is to show how a game of Go (Weiqi, baduk, Igo) can serve as a model representation of the ontological-metaphysical aspect of the actor–network theory (ANT). An additional objective is to demonstrate in return that this ontological-metaphys⁠ical aspect of ANT represented on Go/Weiqi game model is able to highlight the key aspect of this theory—onto-methodological praxis

Análise da subsidencia xerada pola escavación de dous túneles utilizando máquinas tuneladoras EPB (Earth Pressure Balance). Estudio da relación entre as variables de perforación e os asentamentos inducidos.

Currently the development in the use of underground space in urban environments is being instrumental in the planning and management of cities. This use of underground space arises as a result of the growth of cities, demanding infrastructure that accommodate and respond to all that the city needs demand. One of the key pieces to carry out sustainable urban development is improving its transport and communication. For this, new rail and road networks are being designed and implemented using the latest technologies in underground excavations. An example of development of underground space for improving the transport network is the one that is running in London; Crossrail. Crossrail is the largest underground construction project that is currently underway in Europe. It is the development of a new railway network that would connect the West Zone (Reading) with the East (Abbey Wood and Shenfield) London area, through the British capital. A total of 42 km of tunnels have been excavated tunnel boring machines used. 10 sections of tunnels have been dug with 8 TBMs that have passed under the city, sharing space with the underground network in London, the Thames river, large Racacielos, old foundations, stations, collectors and underground rivers at depths up 40 m. This urban environment requires absolute control of the subsidence that may arise. The objective is to determine the influence that the excavation of two tunnels by EPB, has generated over the seats and set a proceeding that, depending on the evolution of the excavation, anticipate the possibility of generating a seat surface.Actualmente el desarrollo en el uso del espacio subterraneo en entornos urbanos esta siendo pieza clave en la planificacion y gestion de las ciudades. Este uso del espacio subterrano surge como la consecuencia del crecimiento de las ciudades, demandando infraestructuras que den cabida y respuesta a todas las necesidades que la ciudad demanda. Una de las piezas clave para poder llevar a cabo un desarrollo urbano sostenible es la mejora de su red de transporte y comunicacion. Para ello, nuevas redes ferroviarias y viarias se estan diseñando y ejecutando, utilizando las ultimas tecnologias en excavaciones subterraneas. Un ejemplo de desarrollo del espacio subterraneo para la mejora de la red de transporte es el que se esta ejecutando en Londres; Crossrail. Crossrail es el mayor proyecto de construccion subterraneo que se esta realizando actualmente en Europa. Consiste en el desarrollo de una nueva red ferroviaria que conectara la la zona Oeste (Reading) con la zona Este (Abbey Wood y Shenfield) de Londres, atravesando la capital britanica. Un total de 42 km de tuneles han sido excavados utilizado maquinas tuneladoras. 10 tramos de tuneles se han excavado con 8 tuneladoras que han pasado por debajo de la ciudad, compartiendo el espacio con la red de metro de Londres, el rio Thames, grandes racacielos, antiguas cimentaciones, estaciones, colectores y rios subterraneas a profundidades de hasta 40 m. Este entorno urbano exige un control absoluto de las subsidencias que se puedan generar. El objetivo es determinar la influencia que la excavacion de dos tuneles mediante EPB, tiene sobre los asientos generados y establecer un procedimento que, en funcion de la evolucion de la excavacion, anticipe la posibilidad de generar un asiento en superficie.Actualmente o desenvolvemento no uso do espazo subterráneo en ambientes urbanos está fundamental para a planificación e xestión das cidades.

Este ambiente urbano esixe control absoluto da subsidência que poida xurdir. O obxectivo é determinar a influencia que a escavación de túneles por dous EPB, xerou ao longo dos asentos e establecer un proceso que, dependendo da evolución da excavación, prevista a posibilidade de xerar unha superficie de asento

Overcoming Barriers in a Shift Towards a Sustainable Transportation System

"The three parts of this portfolio provide a critical perspective on public transit infrastructure, primarily in the Greater Toronto and Hamilton Area (GTHA), but which also strives for wider applicability. The first paper, “The Contradictions of Splintered Network-Building,” proposes that the spate of public transit physical infrastructure projects proposed in The Big Move¸ 2008 regional transportation plan for the GTHA, can be described as a process “splintered network building.” This entails an attempt to build a regional public transit system relying on neoliberal practices that would usually be associated with the fragmentation of networked infrastructures operated by state monopolies. The paper argues that The Big Move represents an infrastructure plan, rather than a comprehensive scheme to improve public transit in the region. The second paper, “Rapid Transit as a Suburban Renewal Project,” uses York Region’s Viva bus rapid transit system as an example of emergent suburban rapid transit. The paper identifies suburban rapid transit as public transit in the form of either light rail or bus rapid transit that connects within suburbs, rather than a more typical form of transit infrastructure that links peripheries to urban centres. The paper demonstrates that while these projects can deliver real improvements in the use value of public transit, they are also entrusted with the task of urbanizing the suburbs by attracting speculative real estate development. The final part of the portfolio is a photo essay documenting the various forms of development that occur next to transit, and which serve to create “places of transit.” It is intended as a visual representation of one of the exchange value orientations of public transit infrastructure.
