Nonparametric Regression Analysis Of Cyclist Waiting Times Across Three Behavioral Typologies, Jeremy Walker, Cristian Poliziani, Cristina Tortora, Joerg Schweizer, Federico Rupi

Faculty Research, Scholarly, and Creative Activity

This paper seeks to predict the average waiting time, defined as the time spent moving at 1 ms−1 or less, of urban bicyclists during rush hours while performing different maneuvers at intersections. Individual predictive models are built for the three cyclist typologies previously identified on a large database of GPS traces recorded in the city of Bologna, Italy. Individual models are built for the three cyclist typologies and bootstrapping has confirmed the validity and robustness of the results. The results allow the integration of waiting times in route choice models for cyclists, thus improving the rational bases by which cyclists …

A Viewpoint On Accent Services: Framing And Terminology Matter, Vikas Grover, Aravind Namasivayam, Nidhi Mahendra

Faculty Research, Scholarly, and Creative Activity

Purpose: The purpose of this article is to offer a contemporary viewpoint on accent services and contend that an equity-minded reframing of accent services in speech-language pathology is long overdue. Such reframing should address directly the use of nonpejorative terminology and the need for nurturing global linguistic diversity and practitioner diversity in speech-language pathology. The authors offer their perspective on affirmative and least-biased accent services, an in-depth scoping review of the literature on accent modification, and discuss using terms that communicate unconditional respect for speaker identity and an understanding of the impact of accent services on accented speakers. Conclusions: Given …

Congestion Costs And Scheduling Preferences Of Car Commuters In California: Estimates Using Big Data, Jinwon Kim, Jucheol Moon

Mineta Transportation Institute

On average, California car commuters waste 4–5 minutes per morning commute due to congestion. Multiplied across all California car commuters, those few minutes entail a yearly total of approximately 2.3 billion hours of time wasted, costing 6 billion dollars. The objective of this study is to quantify congestion costs and determine how commuters adapt to the level of congestion they face (i.e., commuters’ scheduling utility functions). To that end, this research developed a model of trip scheduling under congestion to construct California commuters’ travel-time profiles, i.e., the menu of travel times that each individual would likely face according to alternate …

Optimizing Multimodal Transportation Access To Support Commuting Among Low-Income Transit Riders With Social Distancing, Shailesh Chandra, Vivek Mishra

Mineta Transportation Institute

During the COVID-19 pandemic, LA Metro has encouraged social distancing among passengers—especially at stations of high-demand routes—and has increased fixed-route transit (FRT) services. However, potential impacts of social distancing on the performance of FRT services remain mostly unknown. This research evaluates the accessibility of FRT buses with social distancing using the ridership data collected on four FRT routes: 105, 108, 111, and 115 of the LA Metro's A Line stations located in low-income neighborhoods. This research shows that social distancing of six feet can impact FRT's accessibility to destination stations, and maximum accessibility is achieved only for a certain number …

Lockdowns As A War On The Poor: Looking At Outcomes In Silicon Valley, John B. Estill

Faculty Research, Scholarly, and Creative Activity

COVID-19 has led to unprecedented state-sponsored assaults on individual liberty including mask requirements, lockdowns, and mandatory testing and vaccinations. Unfortunately, these broad restrictions have multiple unintended consequences beyond the simple stripping away of individual rights. Silicon Valley, centered in Santa Clara County, represents a particularly compelling case. There has been much dialogue about the digital divide separating poor service workers from wealthy techies, and mandatory lockdowns have had a particularly damaging effect on the divide. They will continue to have negative ramifications long into the future.

Examining The Effects Of Precision Scheduled Railroading On Intercity Passenger And High-Speed Rail Service, John G. Green, Francis J. Miller

Mineta Transportation Institute

More than just scheduling terminal-to-terminal trips for trains, “Precision Scheduled Railroading” (PSR) creates entire point-to-point trip plans for individual railroad shipments. Since precision execution was first put into practice, the benefits to shipment arrival reliability and to freight railroads’ profitability have been demonstrated by its use in several Class One freight railroads. However, the effects of the PSR operating strategy on passenger railway operations in shared freight/passenger corridors has not been studied in detail. This research examines the effects of PSR railroad operations on passenger railways, including measuring “Host Railroad Minutes of Delay per 10,000 Train-Miles” and “On-Time Performance” of …

Whitt, Hong Zhang

Faculty Research, Scholarly, and Creative Activity

The inventory and variability of oceanic dissolved inorganic carbon (DIC) is driven by the interplay of physical, chemical, and biological processes. Quantifying the spatiotemporal variability of these drivers is crucial for a mechanistic understanding of the ocean carbon sink and its future trajectory. Here, we use the Estimating the Circulation and Climate of the Ocean-Darwin ocean biogeochemistry state estimate to generate a global-ocean, data-constrained DIC budget and investigate how spatial and seasonal-to-interannual variability in three-dimensional circulation, air-sea CO2 flux, and biological processes have modulated the ocean sink for 1995–2018. Our results demonstrate substantial compensation between budget terms, resulting in distinct …

Nonlinear Dynamics Of The Non-Hermitian Su-Schrieffer-Heeger Model, Pieter M. Gunnink, Benedetta Flebus, Hilary M. Hurst, Rembert A. Duine

Faculty Research, Scholarly, and Creative Activity

We numerically determine the robustness of the lasing edge modes in a spin-torque oscillator array that realizes the non-Hermitian Su-Schrieffer-Heeger model. Previous studies found that the linearized dynamics can enter a topological regime in which the edge mode is driven into auto-oscillation, while the bulk dynamics are suppressed. Here we investigate the full nonlinear and finite-temperature dynamics, whose understanding is essential for spin-torque oscillators-based applications. Our analysis shows that the lasing edge mode dynamics persist in the nonlinear domain for a broad range of parameters and temperatures. We investigate the effects of perturbations relevant to experimental implementations and discuss which …

The Interaction Of Vortical Flows With Red Cells In Venous Valve Mimics, Zyrina Alura C. Sanchez, Vignesha Vijayananda, Devin M. Virassammy, Liat Rosenfeld, Anand K. Ramasubramanian

Faculty Research, Scholarly, and Creative Activity

The motion of cells orthogonal to the direction of main flow is of importance in natural and engineered systems. The lateral movement of red blood cells (RBCs) distal to sudden expansion is considered to influence the formation and progression of thrombosis in venous valves, aortic aneurysms, and blood-circulating devices and is also a determining parameter for cell separation applications in flow-focusing microfluidic devices. Although it is known that the unique geometry of venous valves alters the blood flow patterns and cell distribution in venous valve sinuses, the interactions between fluid flow and RBCs have not been elucidated. Here, using a …
