Examining The Effects Of A Bike And E-Bike Lending Program On Commuting Behavior, Dillon T. Fitch, Zeyu Gao, Lucy Noble, Terry Mac

Mineta Transportation Institute

In 2015, Google added a new transportation demand management (TDM) program to increase bike commuting to their two main campuses in Mountain View and Sunnyvale, California. An initial survey of employees indicated that bike ownership and worry about maintenance were primary bicycling barriers. With this information, Google began a program that loaned high-quality electric-assisted and conventional bicycles for a period of six months at no cost to interested employees. This research evaluates the effectiveness of the program at changing travel behavior to the corporate campuses by using self-reported and smartphone-integrated travel data. The lending program at Google represents one of, …

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 …

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 …

Ecosystem Duties, Green Infrastructure, And Environmental Injustice In Los Angeles, Sayd Randle

Research Collection College of Integrative Studies

In Los Angeles, water managers and environmentalist NGOs champion green infrastructure retrofits, installations intended to maximize the water-absorbing capacity of the urban landscape. In such arrangements, the work of water management is necessarily spread among a more-than-human community, including (but certainly not limited to) humans, plants, soils, and gravels. This article analyzes the human labor within these collaborations, tracking when and how this work gets enrolled in networks of water management and circuits of value. I develop the term ecosystem duties to characterize these exertions and as a useful analytic for assessing emergent dynamics of environmental justice.

Individuals who walk and cycle experience a variety of health and economic benefits while simultaneously benefiting their local environments and communities. It is essential to correctly obtain pedestrian and bicyclist counts for better design and planning of active transportation-related facilities. In recent years, crowdsourcing has seen a rise in popularity due to the multiple advantages relative to traditional methods. Nevertheless, crowdsourced data have been applied in fewer studies, and their reliability and performance relative to other conventional methods are rarely documented. To this end, this research examines the consistency between crowdsourced and traditionally collected count data. Additionally, the research aims …

A Geographical Contribution On Interurban Passenger Rail Transportation In The United States, Matthieu Schorung

Mineta Transportation Institute

Why does the rail infrastructure of the United States lag behind those of many other developed countries? Where is U.S. high-speed rail? This research approaches this in a dilemma by exploring Amtrak’s traditional rail services and high-speed rail projects in the nation to understand the workings of public rail transportation policies, what they contain, and how they are developed and pursued by the different stakeholders. This research utilizes case studies and a multiscale approach to analyze the territorialization of intercity rail transportation policies. The analysis demonstrates the emergence of a bottom-up approach to projects, notably apparent in the California HSR …

Parking infrastructure remains one of the least catalogued infrastructure but is perhaps the most spatially dominating set of assets. This research estimates the extent and location of parking supply, including on-street and off-street spaces for the nine-county Bay Area. This parking space inventory is the most detailed assessment of parking infrastructure produced …

A Review Of Environmental Vulnerabilities Related To Nepal’S Graduation Process From Least Developed To A Developing Country Status, Ambika P. Adhikari, Keshav Bhattarai, Basu Sharma

Himalayan Research Papers Archive

Nepal has long aspired to graduate from the Least Development Country (LDC) to Developing Country category as defined by the United Nations system. Nepal had met two of the three graduating criteria and could have technically graduated from the LDC status in 2015. However, based on the Nepal government’s request to defer the review, the new 2021 assessment by the United Nations Committee for Development Policy (CDP) recommended that the country should graduate from the LDC status by 2026. The graduation requires not only meeting pre-defined development-related thresholds, but also maintaining sustained improvements in at least two consecutive assessments in …
