Uncovering Merchants’ Willingness To Wait In On-Demand Food Delivery Markets, Jian Liang, Ya Zhao, Hai Wang, Zuopeng Xiao, Jintao Ke

Research Collection School Of Computing and Information Systems

While traditional on-demand food delivery services help restaurants reach more customers and enable doorstep deliveries, they also come with drawbacks, such as high commission fees and limited control over the delivery process. White-label food delivery services have emerged as an alternative, ready-to-use platform for restaurants to arrange delivery for customer orders received through their applications or websites, without the constraints imposed by traditional on-demand food delivery platforms or the need to develop an in-house delivery operation. Although several studies have investigated consumer behavior when using traditional on-demand food delivery services, there is limited research on merchants’ behavior when adopting white-label …

Effective Strategies To Mitigate The Impact Of Cargo Shipment Abandonment, Ozoemenam Peter Peter Ohagwu

Walden Dissertations and Doctoral Studies

Business leaders in multiple U.S. exporters refuse to pay freight charges and abandon their cargo shipments, leaving shipping business leaders with monetary losses. Some small and medium-sized U.S.-based shippers lack effective strategies to address the risk of cargo shipment abandonments. Grounded in the theory of constraints, the purpose of this qualitative pragmatic inquiry study was to explore the effective strategies used by small and medium-sized U.S.-based shippers to successfully mitigate the risk of cargo shipment abandonment. The participants included three U.S. shipping industry leaders from non-vessel-operating common carriers and three from vessel-operating common carriers, all with an average of 25 …

Bike Buses: An Evaluation Of An Emerging Active Transportation To School Intervention, Evan Howington, John H. Macarthur, Nathan W. Mcneil

PSU Transportation Seminars

Bike Buses are a relatively new form of Active Transportation to School (ATS) that have gained popularity in Europe and the United States in recent years. Generally, a bike bus consists of one or more adult supervisors, often parents, who guide a group of students along a defined ‘route’ to one or more schools. Using literature from the last 15 years published on ATS in North America, we identify four thematic areas of influence on Bike Buses: school policies, parent and student attitudes and behaviors, the urban environment, and the street environment. We conclude that Bike Buses can be situated …

Exploring Determinants Of Transit Recovery After The Covid-19 Pandemic, Udit Khandelwal

Dissertations and Theses

The COVID-19 pandemic significantly disrupted public transit systems across the US, resulting in substantial declines in ridership and revenue. At the same time, ridership has increased to different levels in cities. This thesis explores the determinants of transit recovery in American cities post-pandemic. It analyzes data from the National Transit Database (NTD) and employs a two-stage least squares (2SLS) regression model first laid out by Taylor et al. (2008) for data from 2000. Similar to the results of that paper, the thesis finds strong correlation between transit ridership and variables for transit supply and urban and demographic characteristics for 2019 …

Ghg Inventory From Building Washington State Department Of Transportation Roadways, Milad Ashtiani

PSU Transportation Seminars

State departments of transportation (DOTs) are increasingly focusing on reducing greenhouse gas (GHG) emissions, especially with new regulations like the Buy Clean Acts in California, Oregon, and Washington. This project, in collaboration with the Washington State Department of Transportation (WSDOT), aims to assess the agency's carbon emissions through a life cycle assessment of construction materials such as cement, concrete, steel, and asphalt, which are now under heightened scrutiny.

While WSDOT has already implemented strategies to reduce Scope 1 and Scope 2 emissions (related to direct and energy-related activities), there has been limited focus on Scope 3 emissions—those generated upstream in …

The Impacts Of A Multimodal Safety Project On North Lombard Street In Portland, Oregon, Jason Anderson

PSU Transportation Seminars

North Lombard Street/US-30 Bypass is a critical corridor in North Portland, serving both commercial and residential interests. This corridor is also ranked 11th in terms of fatal and serious injury crashes in Portland. The Oregon Department of Transportation and the Portland Bureau of Transportation undertook a reconfiguration to improve multimodal safety and accessibility for all users. The reconfiguration happened between North Fiske Ave and North Boston Ave. Improvements included additional curb ramps that meet ADA standards, safer crosswalks with fewer lanes to cross, buffered bike lanes, new pavement and center turn lanes, traffic signals, and RRFBs and median refuge islands. …

Transportation Decarbonization: A State Perspective, Tara Weidner

PSU Transportation Seminars

Oregon continues to be a leader in Transportation Decarbonization efforts nationally. The webinar will outline the state’s transportation GHG reduction roadmap, developed in 2012 to tackle legislatively mandated GHG reduction goals, with associated GHG targets for the state’s 8 metropolitan areas. Learn how this north star has guided our collective efforts within the state. How monitoring and new initiatives and regulations have kept us on course to these ambitious goals. And what actions remain to close the gap, both systematic changes at state and local levels, as well as individual choices by private firms and households. Actions that will both …

Construction Contracting In The Zero Emission Transportation Sector: Evidence From Underrepresented Businesses, Gökçe Soydemir, Orestis P. Panagopoulos

Mineta Transportation Institute

This study investigates the degree to which underrepresented construction contractors face challenges in California's zero-emission transportation sector to devise a simpler and more efficient bonding structure. Using a survey dispersed over underrepresented businesses across the state, the study provides several suggestions for a statewide bonding program that caters to the needs of contractors. Both qualitative and quantitative methods are used in the study. The survey data are evaluated using econometric tools to analyze whether there are any statistically significant associations between contractors' characteristics and their industry experiences. Focus groups and focused interviews are conducted to identify those perspectives the survey …

Are California’S Local Jurisdictions Disproportionately Directing Growth Toward Existing Disadvantaged Communities? Evidence From The Southern California And San Francisco Bay Area Regions, Shishir Mathur, Christopher Ferrell

Mineta Transportation Institute

Communities across the United States are striving to promote smart urban growth through compact urban infill residential development. They are doing so to mitigate sprawl's negative fiscal, environmental, social, and physical impacts, strengthen land use-housing-transportation linkages, and develop at densities needed for well-functioning public transit. Some states, such as California, have gone a step further by linking compact urban infill development as critical to meeting greenhouse gas (GHG) reduction targets. Anecdotal evidence suggests some California local jurisdictions are planning disproportionately large amounts of new urban development in disadvantaged communities (DACs). However, empirical evidence is lacking. This study aims to fill …

Measurement And Prediction Of Transit System Performance Using Probe Data Generated Through Dsrc And Non-Dsrc Technologies, Gregory L. Newmark

Mineta Transportation Institute

This research explores the application of two different probe data standards to transit performance measurement. The first section chronicles the proposed and implemented transit uses of dedicated short-range communication (DSRC) technologies during the two decades between the standard’s emergence and its announced sunset. The research finds that, despite proposed applications across safety, operation, and information domains, DSRC never became embedded in transit operations. By contrast, the general transit feed specification (GTFS) standard with its real-time (RT) extension has been widely embraced and offers the potential to use the associated VehiclePosition messages as probe data to generate detailed transit performance metrics. …

A Comprehensive Ml And Ai Framework For Intersection Safety: Assessing Contributing Factors, Surrogate Safety Measures, Non-Compliance Behaviors, And Cost-Inclusive Methodology, Deep Patel

Theses and Dissertations

Intersection safety, particularly in traffic management, has emerged as a pressing concern due to its substantial contribution to road crashes and fatalities. In recent years, understanding road users' behavior and conflicts at intersections has become essential for evaluating traffic safety. According to the Federal Highway Administration (FHWA), in 2020, over 50% of fatal and injury crashes occurred at or near intersections, necessitating further investigation. This study addresses this issue through an innovative blend of comprehensive literature review, advanced machine learning algorithms, artificial intelligence (AI) technologies, surrogate safety measures (SSMs), non-compliance behavior, and emphasizing the economic aspects of traffic incidents. First, …
