Ticket To The Past: A Political History Of The Mexico City Metro, 1958-1969, Maxwell E.P. Ulin May 2017

Ticket To The Past: A Political History Of The Mexico City Metro, 1958-1969, Maxwell E.P. Ulin

Grand Valley Journal of History

This essay outlines the historic political battle between Mexico's longest serving mayor, Ernesto Uruchurtu, and the nation's president, Gustavo Diaz Ordaz, over the construction of what would become the second largest subway system in the Western Hemisphere, The Mexico City Metro. The conflict, which eventually resulted in Uruchurtu's resignation, was characterized by latent political tensions between the PRI and Mexican middle class that would erupt in 1968 and lead to the ultimate decline of PRI hegemony. I thus argue that the new Metro project did not reflect Mexico's democratic modernization--as its supporters meant it to do--but rather the vestiges of …


The Causal Effect Of Bus Rapid Transit On Changes In Transit Ridership, Orion T. Stewart, Anne Vernez Moudon, Brian E. Saelens Mar 2017

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 …

Data-Driven Spatial Modeling For Quantifying Networkwide Resilience In The Aftermath Of Hurricanes Irene And Sandy, Yuan Zhu, Kun Xie, Kaan Ozbay, Fan Zuo, Hong Yang

Computational Modeling & Simulation Engineering Faculty Publications

In recent years, the New York City metropolitan area was hit by two major hurricanes, Irene and Sandy. These extreme weather events disrupted and devastated the transportation infrastructure, including road and subway networks. As an extension of the authors' recent research on this topic, this study explored the spatial patterns of infrastructure resilience in New York City with the use of taxi and subway ridership data. Neighborhood tabulation areas were used as the units of analysis. The recovery curve of each neighborhood tabulation area was modeled with the logistic function to quantify the resilience of road and subway systems. Moran's …

How Bicycling Sharing System Usage Is Affected By Land Use And Urban Form: Analysis From System And User Perspectives, Ahmadreza Faghih-Imani, Naveen Eluru, Rajesh Paleti Jan 2017

How Bicycling Sharing System Usage Is Affected By Land Use And Urban Form: Analysis From System And User Perspectives, Ahmadreza Faghih-Imani, Naveen Eluru, Rajesh Paleti

Civil & Environmental Engineering Faculty Publications

There is a rapid growth of bicycle-sharing systems (BSS) around the world. Cities are supporting these systems as a more sustainable transport mode for short trips. Given the relatively recent adoption of BSS, there is substantial interest in understanding how these systems impact urban transportation. In this paper, we examine the functioning of the hugely successful New York City CitiBike system. We focus on the interaction of BSS with land-use and built environment attributes and the influence of weather condition and temporal characteristics on BSS usage. Towards this end, CitiBike system is analyzed along two dimensions: (1) at the system …


Impact Of Trucking Network Flow On Preferred Biorefinery Locations In The Southern United States, Timothy M. Young, Lee D. Han, James H. Perdue, Stephanie R. Hargrove, Frank M. Guess, Xia Huang, Chung-Hao Chen Jan 2017

Impact Of Trucking Network Flow On Preferred Biorefinery Locations In The Southern United States, Timothy M. Young, Lee D. Han, James H. Perdue, Stephanie R. Hargrove, Frank M. Guess, Xia Huang, Chung-Hao Chen

Electrical & Computer Engineering Faculty Publications

The impact of the trucking transportation network flow was modeled for the southern United States. The study addresses a gap in existing research by applying a Bayesian logistic regression and Geographic Information System (GIS) geospatial analysis to predict biorefinery site locations. A one-way trucking cost assuming a 128.8 km (80-mile) haul distance was estimated by the Biomass Site Assessment model. The "median family income," "timberland annual growth-to-removal ratio," and "transportation delays" were significant in determining mill location. Transportation delays that directly impacted the costs of trucking are presented. A logistic model with Bayesian inference was used to identify preferred site …


Enhancing Capacity And Managing Demand To Increase Short-Term Throughput On The San Francisco-Oakland Bay Bridge, Kevin Reid Carstens Dec 2016

Enhancing Capacity And Managing Demand To Increase Short-Term Throughput On The San Francisco-Oakland Bay Bridge, Kevin Reid Carstens

Master's Theses

While there are many proposals for fixing congestion between San Francisco and Oakland in California by adding a new bridge or tube, these solutions will take decades to implement even though a solution is needed now. This thesis assesses sixteen different strategies for reducing congestion in the short-term in the four categories of improving transit, promoting carpooling, implementing intelligent transportation systems practices, and incentivizing alternatives to using the Bay Bridge. Top priorities include HOV improvements on the West Grand Avenue and Powell Street onramps, altering WestCAT Lynx and BART transit services, partnering with rideshare apps to increase transit station accessibility …


Spaceways: Airspace In Outer Space, Scott Haeffelin Nov 2016

Spaceways: Airspace In Outer Space, Scott Haeffelin

Space Traffic Management Conference

Forecasted future demand in space travel is driving the need for the development of space traffic management. Currently, orbital space traffic is mostly unregulated with internationally agreed upon best practices and self-interest driving space operators to avoid collisions with other spacecraft. This paper explores the future of space travel by presenting a concept of creating “airspace in space” or spaceways to manage the ever growing volumes of space traffic. Spaceways are analogous to airspace for aircraft with the goal of increasing levels of safety and reducing probabilities of collision. These goals can be achieved by creating traffic rules, defining valuable …


Determining The Interruption Of Services While Performing V2i Communication Using The Spmd Prototype, Binaya Raj Joshi Nov 2016

Determining The Interruption Of Services While Performing V2i Communication Using The Spmd Prototype, Binaya Raj Joshi

Student Work

The use of Vehicle to Vehicle (V2V), Vehicle to Infrastructure (V2I), Vehicle to Roadside Unit (V2R) and Vehicle to Other (V2X) communications are increasingly applied over existing and upcoming transportation means by the United States Department of Transportation (USDOT) and other federal agencies. From previous statistical data, these technologies would primarily avoid or mitigate vehicle crashes and would provide more safety, mobility and various other benefits on the roads (“Traffic Safety Facts 2012,” 2013; “Traffic Safety Facts 2013” 2014). During the communication processes between vehicles, infrastructures and roadside units’ various sensitive data such as positions and speed of the vehicles, …

Improving Pathways To Transit For Persons With Disabilities, Stephanie Dipetrillo, Andrea Lubin, Anastasia Loukaitou-Sideris, Carla Salehian, Stephen Gibson, Kristen William, Theodore Trent Green Aug 2016

Improving Pathways To Transit For Persons With Disabilities, Stephanie Dipetrillo, Andrea Lubin, Anastasia Loukaitou-Sideris, Carla Salehian, Stephen Gibson, Kristen William, Theodore Trent Green

Mineta Transportation Institute

Persons with disabilities can achieve a greater degree of freedom when they have full access to a variety of transit modes, but this can only be achieved when the pathways to transit – the infrastructure and conditions in the built environment – allow full access to transit stops, stations, and vehicles. Since passage of the Americans with Disabilities Act (ADA) in 1990, many transit agencies and governmental jurisdictions have made significant progress in this area. Policy initiatives, incremental enhancements, modifications, and other measures undertaken by transit agencies and their partners have significantly improved access to transit for persons with disabilities, …

Use Of Cycling Paths Along The Morogoro Brt Line, Ford Sanger

Independent Study Project (ISP) Collection

As the urban population continues to increase rapidly in Dar es Salaam it will become increasingly important to find sustainable means of urban transportation. With planned infrastructure improvements in the city to help alleviate traffic congestion, bicycles, which represent a largely underutilized form of urban transportation, have the potential to play a large role in the future of the city. Through background research, direct observations, community surveys, and interviews, both formal and informal, this study sought to understand the impact of the recent addition of bike lanes along the first phase of the Dar Bus Rapid Transit line. It was …

Climate Adaptation And Resiliency Planning For New England Communities: First Steps And Next Steps, Charles Colgan, Jack D. Kartez Ph.D., Martha P. Sheils

Publications

Hurricane Irene tearing Vermont roads and bridges apart and Superstorm Sandy ripping through coastal areas; such phenomenal events are being joined by more frequent rain, tide and wind impacts that are disrupting communities and risking property and lives. New challenges arise from weather events that are driven by a less stable climate. The key difference between what communities already plan for and climate adaptation planning is the level of uncertainty about how impacts may change in the future and the potentially enormous and devastating damages that a community may sustain. This Guide presents an overview of that task, with links …


Exchange Patterns And Relations In Collaborative Governance., Charles Wharton Kaye-Essien May 2016

Exchange Patterns And Relations In Collaborative Governance., Charles Wharton Kaye-Essien

Electronic Theses and Dissertations

Collaborative governance has received considerable attention in recent years. From environmental resource management to public safety, collaborative governance continues to play a vital role in regional problem solving. In spite of this increasing popularity previous attempts to model the political, economic, and demographic determinants of collaboration have in most cases produced inconsistent results, thereby undermining the ability to generalize from such findings. Additionally, our understanding of the relational patterns that emanate from collaborative agreements remains fairly rudimentary. The main objective of this research is to address some of the gaps in the literature and improve our understanding of collaborative governance …


Assessing Transportation Management Associations (Tmas) In Rural Maine As An Approach To Increase Transportation Options, Vicki L. Rusbult May 2016

Assessing Transportation Management Associations (Tmas) In Rural Maine As An Approach To Increase Transportation Options, Vicki L. Rusbult

All Theses And Dissertations

Maine has the distinction of being a beautiful state defined by natural forests, crystal-clear lakes, and a landscape unblemished by the usual marks of the densely populated regions of the U.S. The downside to this rural beauty is the remoteness of the sparsely populated communities which present challenges to residents who are unable to drive themselves to procure basic services because of physical, legal, or economic conditions.

Many rural residents are unable to rely on personally-owned, single driver vehicles. According to the Maine Department of Transportation Bureau of Planning (2013), the Eastern Maine region has an estimated unmet need (number …

Paying For Infrastructure In An Urban Environment: Roles Of Ideological Beliefs And Self-Interest In Support For Two Funding Mechanisms, Juita-Elena (Wie) Yusuf, Lenahan O'Connell, Khairul A. Anuar, Kaitrin Mahar

School of Public Service Faculty Publications

This study examines public preferences for two revenue options—fuel taxes and tolls—to finance transportation infrastructure in an urban area with the use of the results of a survey of residents of the Hampton Roads region of southeastern Virginia. Specifically, the study addresses two related research questions: (a) To what extent do residents support instituting tolls, increasing the fuel tax, or both? (b) What roles do self-interest and ideological beliefs play in support of increasing the fuel tax, imposing tolls, or doing both? The study finds that 50% of respondents expressed a willingness to support fuel taxes or tolls for infrastructure, …

Blurring The Lines: The Overlapping Interests Of High Altitude Unmanned Aircraft, Commercial Space, And Aviation Policy, Ruth E. Stilwell Nov 2015

Blurring The Lines: The Overlapping Interests Of High Altitude Unmanned Aircraft, Commercial Space, And Aviation Policy, Ruth E. Stilwell

Space Traffic Management Conference

The commercialization of space operations, coupled with the rapid development in unmanned aircraft systems creates a new policy dynamic between otherwise disparate industries. Existing structures do not adequately address issues of access, governance, and sovereignty across the distinct domains of air transport, space operations, and high altitude unmanned aircraft operations. Globally, aviation policy and space policy have evolved independently as distinct fields. High altitude unmanned aircraft are rapidly increasing utilization of airspace not previously occupied by civil aircraft or spacecraft, where regulation of both safety and access is sparse. Rather than consider operations in this airspace as a third category …

The New Panama Canal In A Global Context, Herman L. Boschken Jun 2015

The New Panama Canal In A Global Context, Herman L. Boschken

Faculty Publications, School of Management

Without the "container revolution" (1970-present) and its redesign of seaport and maritime-trade infrastructures, globalization as we know it would not exist. With the recent enlargements of the Panama and Suez Canals, many new implications for U.S. economic trade are unfolding. This presentation at the Commonwealth Club of California, outlines recent changes in world trade and infrastructure development, and poses five factors that will likely determine winners and losers in the unfolding developments of this highly competitive world trade-route system.

Oregon Highway Cost Allocation Study: Carbon Tax Issue Paper, Portland State University. College Of Urban And Public Affairs. Northwest Economic Research Center Mar 2015

Oregon Highway Cost Allocation Study: Carbon Tax Issue Paper, Portland State University. College Of Urban And Public Affairs. Northwest Economic Research Center

Northwest Economic Research Center Publications and Reports

The basic insight behind carbon pricing is not new, and is based in mainstream economic theory. If market interactions are leading to the overuse of resources outside of the market, imposing a price on the overused resource will bring it into the market and increase efficiency. Currently, the negative impacts associated with the release of carbon through fossil fuel combustion is not incorporated into the market. By imposing a price on carbon, fossil fuel consumers are incentivized to reduce their fuel usage. This reduction in fuel demand is not necessarily associated with lower economic output. In fact, depending on the …
