Mad About Late Buses Or Broken Trains? Blame Your Governor, Peter Tomao

Capstones

President Biden's Infrastructure Investment and Jobs Act promised to "expand public transit options across every state" and reduce greenhouse gas emissions while modernizing America's transit systems. But a series of hurdles ranging from recalcitrant local officials to entrenched car culture mean the bill may simply reinforce the status quo.

Summary: The infrastructure planning and implementation process is lengthy in terms of time and resources. In response to an articulated need, proposed solutions are considered and studied, stakeholder support gathered, funding and financing identified, and eventually adopted. There are different equity touchpoints: in the planning and implementation process; in terms of awareness of and ability to pursue projects; and in terms of who pays and who benefits.

Fragmented Or Aligned Climate Action: Assessing Linkages Between Regional And Local Planning Efforts To Meet Transportation Greenhouse Gas Emissions Reduction Targets, Serena E. Alexander, Ahoura Zandiatashbar, Branka Tatarevic

Mineta Transportation Institute

Amid the rising climate change concerns, California enacted Senate Bill 375 (SB 375) to tackle transportation greenhouse gas (GHG) emissions. SB 375 requires Metropolitan Planning Organizations (MPOs) to develop a Sustainable Communities Strategy (SCS), a regional transportation and land use vision plan, to reduce GHG emissions. Meanwhile, a local government can develop a Climate Action Plan (CAP), a non-binding, voluntary plan to reduce GHG emissions that may align with the regional SCS. Recent progress reports indicate California is not making sufficient progress to meet SB 375 emissions reduction targets, which raises important questions: (1) Are the transportation and land use …

Mineta Transportation Institute

The San Joaquin Valley is identified as an area with a high level of particulate matter (PM) in the air, reaching above the federal and state clean air standards (EPA 2019). Many of the cities in the valley are classified as the most polluted cities in the United States for both particulate matter and ozone pollution (American Lung Association, 2021). To resolve this issue, alternative forms of transportation have been considered in transportation planning. In this study, active transportation mode air quality was monitored on selected Woodward Park and Old Clovis trails and urban bike lanes. Real-time aerosol monitors, and …

Infrastructure's (Supra)Sacralizing Effects: Contesting Littoral Spaces Of Fishing, Faith, And Futurity Along Sri Lanka's Western Coastline, Orlando Woods

Research Collection School of Social Sciences

This paper explores the ways in which infrastructural development can cause the sacred to become a source of political legitimacy, and sacred authority to become a politically charged construct. For resource-dependent communities, the ecological damage caused by infrastructural development can cause ostensibly profane issues to be imbued with sacred meaning and value. With sacralization comes the expectation that figures of sacred authority will campaign for justice on behalf of the communities that they represent. However, when the authority evoked comes from outside the boundaries of institutionalized religion, processes of suprasacralization come into play. By exploring infrastructure’s (supra)sacralizing effects, I demonstrate …

Complex Adaptive Systems In A Contentious World, Yasmin Merali

New England Journal of Public Policy

This article is about developing and implementing interventions that are systemically viable in a world that is constantly evolving. Geopolitical and economic forces, environmental stressors, and the weaponization of information confront us with an unprecedented level of complexity, requiring new ways of seeing and being when intervening in conflictual situations. I draw on the Complex Adaptive Systems paradigm to explore how world order emerges from the dynamics of network relationships between the players in the cyber-social landscape. This treatment elaborates on mechanisms underpinning resilience, adaptation, and transformation of socioeconomic systems in turbulent contexts. It emphasizes a need to reconsider conventional …

Enter The Age Of Csywar: Some Reflections On An Emergent Trend, Kumar Ramakrishna

New England Journal of Public Policy

This article uses the current Russian-Ukrainian conflict as a jumping-off point for a broader, preliminary reflection on the continuing evolution of war in the digital age. It is the contention here that we are witnessing an emergent phenomenon of what we might call csywar. Intervening states engaged in csywar—best understood as an indirect, hybrid strategy—seek to attain data, infrastructural, and epistemic dominance over the target state. This article discusses various defensive counter-csywar strategies that target states could pursue, such as fostering data, infrastructural, and epistemic resilience internally, and makes the case for developing deterrent counter-csywar capabilities against hostile intervening states.

Weathering The Storm: Navigating Urban Ecologies Of Communication In Times Of Crisis, Austin Hestdalen

Electronic Theses and Dissertations

This project explores cities as urban ecologies of communication in which crises emerge and are given significance within the dialogic relations cultivated among public actors attempting to make a living, together, within the shared historical-cultural contexts of everyday life. To describe cities as urban ecologies of communication is to describe them in terms of urban communication and its interdisciplinary foundations in the study of rhetoric, philosophy, planning, policy, architecture, sociology, geography, and media. The first chapter introduces the challenges of urban risk and crisis management within the complex ecologies of communication constituted by cities and reviews how ‘risk’ and ‘crisis’ …

Evaluating Barriers To And Impacts Of Rural Broadband Access, Javier Valentín-Sívico

Doctoral Dissertations

"The lack of adequate broadband infrastructure persists in many rural communities. Beyond funding, additional barriers persist, such as digital literacy and community-level self-efficacy. As a result, the first contribution articulates barriers at the organizational level. This work proposes a framework based on the Theory of Planned Behavior to highlight stakeholder dynamics that have constrained Regional Planning Commissions from advancing broadband infrastructure in rural areas. One approach to address these barriers is to provide stakeholders with analytical tools to evaluate the benefits and costs of various broadband options for their community since there is not a one-size-fits-all solution. To this end, …

Estimating The Economic Impacts Of Transportation-Related Supply Chain Disruptions In The Post-Earthquake Environment, Divya Chandrasekhar, Sua Kim, John Downen, Joshua Spolsdoff

TREC Final Reports

Transportation systems play a critical role in maintaining supply chains for effective post-disaster recovery. Modeling the potential economic impact of transportation-related disruptions, therefore, is an important step to promoting pre-event community wide recovery and resilience planning. But existing supply chain and economic impact models are cost prohibitive and overly sophisticated for use by public sector entities with limited resources. There is also limited understanding of how small and medium enterprises (SMEs) adjust to post-disaster transportation disruption and how this experience influences their future preparedness for similar events. This project had two objectives: (1) to analyze the economic impact due to …

Contracting Strategies: A Different Approach To Address Long-Term Performance, Maria Calahorra-Jimenez

Mineta Transportation Institute

For cost-efficiency, public safety, and sustainability, improving long-term performance in highway projects is imperative for public administrations. Project delivery and procurement methods provide an opportunity to align design and construction processes with this goal. While previous studies have explored whether project delivery methods impact the long-term performance of highway projects, these studies did not focus on how core elements within project procurement relate to long-term performance. Thus, to fill this gap, this research explores how and to what extent long-term evaluation criteria are considered in design-build best-value procurement of highway projects. To this end, the team conducted content analysis on …

Connected Simulation For Work Zone Safety Application, Vahid Balali

Mineta Transportation Institute

Every year, over 60,000 work zone crashes are reported in the United States (FHWA 2016). Such work zone crashes have resulted in over 4,400 fatal and 200,000 non-fatal injuries in the last 5 years (FHWA 2016, BLS 2014). Apart from the physical and emotional trauma, the annual cost of these injuries exceeds $4 million-representing significant wasted resources. To improve work zone safety, this research developed a system architecture for unveiling high-risk behavioral patterns among highway workers, equipment operators, and drivers within dynamic highway work zones. This research implemented the use of a connected virtual environment, which is an immersive hyper-realistic …

Mineta Transportation Institute

Timely repairs of pavement defects are essential in protecting an important investment and asset that public agencies have. These repairs may be made as durable “stand-alone” repairs of isolated problems, or as part of preparations for a total resurfacing. This manual provides basic information on the planning, materials and construction aspects of common pavement repairs such as crack sealing, crack filling, and patching, as well as a broader look at other preparations needed for total resurfacing a pavement, whether the resurfacing is a surface treatment or a thin hot mix asphalt (HMA) overlay.

Long-Term Wildfire Reconstruction: In Need Of Focused And Dedicated Pre-Planning Efforts, William S. Harris, Jin Ouk Choi, Jaewon Lim, Yong-Cheol Lee

Civil and Environmental Engineering and Construction Faculty Research

Wildfire disasters in the United States impact lives and livelihoods by destroying private homes, businesses, community facilities, and infrastructure. Disaster victims suffer from damaged houses, inadequate shelters, inoperable civil infrastructure, and homelessness coupled with longterm recovery and reconstruction processes. Cities and their neighboring communities require an enormous commitment for a full recovery for as long as disaster recovery processes last. State, county, and municipal governments inherently have the responsibility to establish and provide governance and public services for the benefit and well being of community members. Municipal governments’ comprehensive and emergency response plans are the artifacts of planning efforts that …

Why We Should Reuse Wastewater, Bridget Sarver

Certified Public Manager® Applied Research

As population and industry grow, the need to reuse wastewater is growing. Aquifers are often the dominant water supplies to surrounding areas. The levels of those aquifers are declining each year. Water loss affects many things like water wells, lakes, and rivers. Lakes and rivers that are used as water sources are seeing a decline in levels. Low water levels and drought occur because of the changing water cycle. Heavy rain and runoff can help refill lakes and rivers; however precipitation does not always fall back on the area that it evaporated from. By reusing wastewater, we will be saving …
