Improving Trip Generation Methods For Livable Communities, Kelly J. Clifton, Nico Larco, Kristina Marie Currans, Jael Wettach-Glosser

TREC Final Reports

Recent efforts to improve trip generation data available for transportation impact analysis of new development include the collection of multimodal trip generation data, development of models that account for the built environment, and new recommendations for practice. Building on a long line of research on transportation and built environment, many studies have identified important features of the surrounding built environment that most impact trip rates and mode shares, building on a long line of research on transportation and the built environment. Despite these improvements in data and methods, less attention is placed on identifying the conditions of the site itself …

Estimating Reliability Indices And Confidence Intervals For Transit And Traffic At The Corridor Level, Travis B. Glick

PSU Transportation Seminars

As congestion worsens, the importance of rigorous methodologies to estimate travel-time reliability increases. Exploiting fine-granularity transit GPS data, this research proposes a novel method to estimate travel-time percentiles and confidence intervals. Novel transit reliability measures based on travel-time percentiles are proposed to identify and rank low-performance hotspots; the proposed reliability measures can be utilized to distinguish peak-hour low performance from whole-day low performance. As a case study, the methodology is applied to a bus transit corridor in Portland, Oregon. Time-space speed profiles, heatmaps, and visualizations are employed to highlight sections and intersections with high travel-time variability and transit low performance. …

Measuring Stress Levels For Real-World On-Road Cyclists: Do Bicycle Facilities, Intersections And Traffic Levels Affect Cyclists' Stress?, Álvaro Caviedes

PSU Transportation Seminars

This research effort presents a novel approach to measure cyclists’ stress: real-world, on-road measurements of physiological stress as cyclists travel across different types of bicycle facilities in various traffic volumes. This study addresses the question of how the characteristics of a bicycle trip affect stress levels using physiological data, specifically GSR. As detailed in the next section, GSR-based studies have been successfully employed for many years in the psychological field to recognize and associate emotions and behaviors to physiological responses. The three research questions examined in this study are: i) Does peak traffic impact cyclists’ stress levels? ii) Do intersections …

A Pathway Linking Smart Growth Neighborhoods To Home-Based Pedestrian Travel, Steven R. Gehrke, Kelly J. Clifton

PSU Transportation Seminars

Land development patterns, urban design, and transportation system features are inextricably linked to pedestrian travel. Accordingly, planners and decision-makers have turned to integrated transportation-land use policies and investments to address the pressing need for improvements in physical activity levels via the creation of walkable communities. However, policy questions regarding the identification of smart growth indicators and their connection to walking remain unanswered, because most studies of the built environment determinants of pedestrian travel: (a) represent the built environment with isolated metrics instead of as a multidimensional construct and (b) model this transportation-land use relationship outside of a multidirectional analytic framework. …

Urban Environmental Performance Index: The Quito Pilot Case, Diego C. Manya, Ryan Thomas, Matthew Moroney

Yale Day of Data

In the context of the adoption of the Sustainable Development Goals (SDG) and its indicators, especially Goal 11, the importance of indicators is paramount to the implementation, monitoring and eventual success of the SDG. However, a review of global sustainability indicators reveals major gaps in coverage, including scientific gaps. Indicators are often siloed, meaning at the urban scale where issues often overlap and intersect, existing indicators do not take into consideration cross-sectoral linkages. Finally, many indicators fail to adequately address social equity or inclusion, a high-priority issue identified as central to new definitions of green economy and sustainable development at …

Avoiding Bus Bunching: From Theory To Practice, Ricardo Giesen

PSU Transportation Seminars

The problem of bus bunching in a high frequency service has been largely studied in the literature.

This phenomenon is produced by three main factors

(i) the variability in travel time between stops; (ii) variations in passenger demand; and (iii) drivers’ heterogeneity.

In order to tackle this phenomenon a wide range of control strategies have been proposed, however, none of them had been successfully implemented on a large transit network with high frequency services.

In this talk, we present a control scheme based on a rolling horizon optimization problem that has been successfully implemented for real-time control of two high …

Looking Forward, Looking Back: Collective Memory And Neighborhood Identity In Two Urban Parks, Sofya Aptekar

Publications and Research

Collective memory and narratives of local history shape the ways people imagine a neighborhood’s present situation and future development, processes that reflect tensions related to identity and struggles over resources. Using an urban culturalist lens and a focus on collective representations of place, I compare two nearby New York parks to uncover why, despite many similarities, they support different patterns of meaning making and use. Drawing on ethnographic observation, interviews, and secondary analysis, I show that multi-vocal and fragmented contexts of collective memory help explain the uneven nature of gentrification processes, with one park serving as its cultural fulcrum while …

No. 07: The Urban Food System Of Mexico City, Mexico, Guénola Capron, Salomón Gonzalez Arellano, Jill Wigle, Ana Luisa Diez, Anavel Monterrubio, Héctor Hidalgo, Jesús Morales, José Castro, Cristina Sánchez-Mejorada, María Concepción Huarte T., María Teresa Esquivel, René Flores

Hungry Cities Partnership

This report provides an overview of Greater Mexico City and its food system. The city’s history, demographic characteristics, geography and economy are first discussed. The city’s urban food system and urban food security are then examined with a particular focus on formal and informal food retail, food expenditure patterns, and policies to combat hunger and food insecurity. Meeting the daily food demands of Mexico City’s over 20 million inhabitants requires the agricultural production of Mexico’s rural areas, its fishing industry and food imports. Food products arrive in the city from around the country in a combination of traditional and highly …

The Farm In The City In The Recent Past: Thoughts On A More Inclusive Urban Historiography, Ruth Glasser

Urban and Community Studies Faculty Writing

The scholarly and journalistic literature usually treats urban agriculture as a new phenomenon, but it is a neglected dimension of urban history. Some U.S. cities, at least in the Northeast, had food-raising and processing practices not just in colonial times but right up until the relatively recent past. Three areas of history are explored that have mostly omitted discussion of city food production but nonetheless provide important frameworks to explore such production: urban development, agricultural, and immigrant history. Woven throughout this piece is evidence from a study of Waterbury, Connecticut. Local food production did not die when the Industrial Revolution …

Thompson St. Corridor: Conceptual Design Recommendations, Ursp 761-902 Studio 1 Class

Urban and Regional Studies and Planning Reports

Graduate students from the Virginia Commonwealth University Masters in Urban and Regional Planning program were asked to develop a comprehensive redesign plan for the Thompson Street Corridor. The proposed plan outlines recommendations for the corridor that align with the City of Richmond’s effort to build stronger and more dynamic neighborhoods for its residents. A vibrant, thriving and livable corridor requires various characteristics, including safety and walkability, a unique architectural identity, robust recreational spaces and cohesive commercial and residential developments. Although the Thompson Street corridor is located between two robust destinations on the southern and northern ends, Carytown and Scott’s Addition, …

Development And Environmental Injustice In Malaysia: A Story Of Indigenous Resistance In Sarawak, May Tay '17

EnviroLab Asia

In 2008, the Federal Government of Malaysian announced an initiative to build 20,000 megawatts of mega dams along a 320km corridor in Sarawak. Named the Sarawak Corridor of Renewable Energy (SCORE), the scheme would create one of five regional development corridors throughout Malaysia, and was part of the government’s strategy to make the state of Sarawak ‘developed’ by 2020 through industrialization and renewable energy development (Recoda). Of the mega dams planned for construction by 2020, three have been completed, with construction for the others underway and the construction process frequently delayed by resistance from local indigenous communities. Indigenous tribe members …

Considerations Of Development In Malaysian Borneo, Zayn Kassam

EnviroLab Asia

Given Malaysia’s vast natural resources, the country has embarked on an ambitious set of development projects capitalizing on the opportunities afforded by extractive industrialization. Global and national demand for oil palm products, timber, and hydropower resources coupled with a governmental development agenda guided by neoliberal market principles has led to both economic growth and social and environmental injustice. This chapter argues for an alternative development model along the lines suggested by Escobar in addressing Malaysia’s path to development and fiscal well-being in a manner that safeguards its cultural and natural resources.

Hydropower, Oil Palm, And Sustainability, Fernando Salud '17

EnviroLab Asia

This reflection touches on the writer’s experiences during the EnviroLab Asia Clinic trip in early 2016 to Borneo, Malaysia and Singapore. The reflection involves two events: a visit to a blockade protesting the construction of a hydroelectric dam and a meeting with the sustainability department of Wilmar, one of the world’s leading palm oil producers. The first event comments on the tension between the need for renewable energy and the destruction of the natural environment and communities due to the particular energy generation technology chosen. This event highlighted the importance of understanding the societal constraints a technology is being installed …

Resisting Dams And Plantations: Indigenous Identity In Sarawak, Wan Ping Chua '17

EnviroLab Asia

The market and community are always intertwined, and sustained through economic power, social obligations and ideologies. In Sarawak, Malaysia, the expansion of land use for the development of cash crops and energy infrastructure has faced resistance from indigenous communities who depend upon land for subsistence lifestyles. In this encounter, values and cultures are reworked, and the ways in which the community and market rely upon each other in the community changes. The examination of the rice and wild foods sustenance lifestyle of the indigenous Kenyah in Sarawak, Malaysia, and resistance against land development projects, suggest that in the conflicts over …

What Does “Sustainable Development” Mean?, Grace Stewart '17

EnviroLab Asia

A recurring theme throughout the EnviroLab Asia clinic trip to Singapore and Malaysian Borneo was the concept of "sustainable development." In this essay, I explore my own thoughts and concerns regarding this phrase, such as the tension that exists between "sustainability" (the maintenance of resources) and the conventional concept of "development" (which consumes resources and can often wreak environmental destruction). I reflect on this tension within the context of environmental issues faced by the Dayak people in Sarawak--the building of the Baram Dam, and the prevalence of oil palm plantations.
