Preconstruction Support Cost Hours Estimating On Caltrans Pavement Rehabilitation Projects, Nigel Blampied, Tariq Shehab, Elhami Nasr, Laxmi Sindhu Samudrala
Mineta Transportation Institute
Because the construction phase accounts for the majority of project costs for pavement rehabilitation projects, most research on infrastructure project cost estimating focuses on that phase, rather than on the preconstruction phases. Nevertheless, costs incurred prior to construction, referred to in this report as "preconstruction costs" are significant and worthy of consideration (See Section 2.1 of the report for a more detailed and precise definition of preconstruction). In the 20202021 fiscal year, for instance, the California Department of Transportation (Caltrans) spent more than $169 million on preconstruction work for pavement rehabilitation projects. This report presents the results of a study …

Historic Downtown Streetscape Plan Price City, Utah, Patricia Beckert
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The idea of a small-town Main Street has profound meaning within the American culture that has prevailed for the past two centuries. Historically, Main Street serves as the beating heart of a community, a place where economic, social, cultural, and civic activities are centered (Francaviglia, 1996; Main Street America, n.d.). Since the beginning of the 19th century, many factors have led to the decline of Main Streets, and despite a variety of efforts from different stakeholders, that decline has only intensified in recent decades (Isenberg, 2008; Orvell, 2014 Howard, 2015). In 1980, after a three-year project conducted by the National …

Electric Vehicle Routing Problem – Models And Algorithms, Hesamoddin Tahami
Engineering Management & Systems Engineering Theses & Dissertations
The transportation sector is a major greenhouse gas emitter that is heavily regulated to reduce its dependence on oil. These regulations along with the growing customer awareness of global warming have led to the investigation of new transportation problems that consider using eco-friendly vehicle fleets. Promising alternatives to traditional fleets include alternative fuel vehicles (AFVs) and electric vehicles (EVs). These twenty-first-century vehicles offer an appealing advantage of consistently reducing their environmental impact, but due to the current technology, they exhibit bothersome limitations. The short driving range along with limited charging infrastructure may consequently cause issues related to range anxiety, i.e., …

The Use And Influence Of Health Indicators In Municipal Transportation Plans, Kelly Rodgers
PSU Transportation Seminars
As a social determinant of health, transportation significantly contributes to well-being through several pathways. Researchers and practitioners have called for health indicators as one way to integrate public health concerns into transportation decision-making. However, it is unclear how indicators are used and what their impact is on policy. This case study of five cities explored how health-related indicators are being used in municipal transportation plans, whether they are institutionalized into transportation agency decision-making processes, and what influence they have on administrative decision-making. In addition, this research also explored the conceptual use of indicators as it relates to social learning and …

Sex In The Cities: A Comparative Analysis Of Vienna And The United States’ Efforts In Gender Mainstreaming Transportation, Sarah Miller
Departmental Honors & Graduate Capstone Projects
The paper focuses on the differences in transportation systems between the United States and Vienna, Austria. Research shows that women have been an overlooked group of people within cities. Due to this, cities have not been designed for them and an example of this is transportation. Some cities like Vienna, Austria have made it their mission to create gender-equitable cities. To better understand this problem women were interviewed who had experience in the Viennese and American systems to analyze the differences. Also, certain government agencies were contacted to understand this problem from a governance standpoint. All of the interviews supported …

Towards Data And Solution-Focused Approaches For Homeless Populations On Publictransit, Anne Nordberg, Jaya Davis, Stephen Mattingly, Nithisha Gudipati, Ebonie Kinney, Hadiisha Butts
TREC Final Reports
People experiencing homelessness frequently rely on public transit systems and facilities as more than a mode of transportation to needed services, but also as safe shelters from weather and danger. This is a challenge for many transit agencies and impacts transit employees and passengers. Dallas and the surrounding counties have the largest homeless population in Texas, and they utilize the services of the Dallas Area Rapid Transit (DART) that serves 220,000 people per day in Dallas County and 12 surrounding counties. While there is much research focused on people experiencing homelessness, there are gaps in understanding how this population utilizes …

TREC Final Reports
Objective: Access to transit can deliver a host of benefits to the riders and to the region. Previous research aiming to study these benefits has primarily relied on data collected from the opening of new routes or transit systems and focused on the general population. Little is known how low-income riders (LIR) react and benefit in response to when the cost barrier to access to transit is removed. With an intention to increase ridership while addressing the needs of transit-dependent riders in the region, TriMet (Portland, OR) expanded the Honored Citizens Program (HCP) in July 2018 to include low-income …

The idea of urban compaction has been long proposed and promoted to address the problem of urban sprawl in many American cities. However, there are still rare successful cases of such implementation in the United States. This study uses a classic gravity model, TELEM (Transpiration, Economic, and Land-Use Model) to examine to what extent a land-use or transportation policy must be regulated to make the urban compaction occur in a typical auto-dependent city—Fresno, California. Five scenarios are considered (BL, L1, L2, T1, and T2), in which the baseline (BL) is a natural growth scenario. Without any policy interventions, the city …

Is It Worth Promoting Battery Swapping? A Social Welfare Perspective On Provider- And Consumer-Side Incentives, Zhaojun Yang, Xu Zu, Jun Sun, Quanlong Lei, Yali Zhang
Information Systems Faculty Publications
In countries that promote further EV diffusion, battery swapping opens up a market outlet for time-sensitive consumers as well as another green policy channel. To better understand this phenomenon from the perspective of policy-making, this study establishes a Hotelling model of a competitive market comprising a battery swapping service provider and a charging service provider. The analyses of three scenarios, no subsidization, consumer subsidization, and provider subsidization, reveal how to maximize social welfare. Considering subsidy amount, consumer time preferences, service time, and operating costs, the findings provide valuable insights for policymakers. Whereas incentive programs are generally helpful for battery swapping …
