Investigating Disparities And Safety Equity In Pedestrian Nighttime Crashes In Michigan, Sia Isaria Mwende

Masters Theses

For the past eleven years (2011 - 2021) in Michigan, 76 percent of all fatal pedestrian crashes occurred at night. Over the same period, about 36 percent of pedestrian nighttime crashes were fatal or incapacitating (KA), while only 25 percent of daytime pedestrian crashes were fatal or incapacitating (KA). Previous studies suggest that, overall, poor neighborhoods and racial minorities are associated with more pedestrian crashes. With more fatal and incapacitating pedestrian crashes occurring at night, it is imperative to examine how these crashes are distributed by economic status and racial makeup. Therefore, this study aims to investigate the racial and …

Equity In Transportation: Data Driven Analysis Of Transportation Services And Infrastructures, Javad Jomehpour Chahar Aman

Civil and Environmental Engineering Theses and Dissertations

Achieving equity in transportation is an ongoing challenge, as transportation options still vary tremendously when it comes to marginalized populations. This dissertation addresses this challenge by conducting a comprehensive review of existing transportation equity literature and identifying two critical gaps: the lack of data-driven approaches to studying spatial mismatch between transportation supply and demand, and limited information on women's perceptions and expectations towards emerging transportation services.

Chapter two introduces the concept of transportation "deserts," specifically transit deserts and walking deserts, and develops data-driven frameworks to identify and investigate neighborhoods with limited transportation service supply but high demand. The frameworks compare …

Analyzing Residential Curbside Collection For Food Waste In Humboldt County, Yvette Lindler

Cal Poly Humboldt theses and projects

The most prevalent material in the California landfill-destined solid waste stream is food. Food waste is not only an economic and social concern, but a significant environmental challenge as well. Most food waste is disposed of in landfills, where it anaerobically decomposes and releases methane, an extremely potent greenhouse gas and driver of climate change. Policies passed in California, including AB 1826 and SB 1383, aim to implement organic waste recycling programs and reduce methane emissions by diverting organic waste from landfills. The technology to process this food waste exists, but these facilities are limited or nonexistent in rural areas …

Assessment Of Regional Bike And Pedestrian Equity In Transportation Plans, Drew Reiter

Graduate Theses, Dissertations, and Problem Reports (ETD)

While community involvement is legally required as a crucial part of the planning process, historically the traditional state-centric approaches to transportation planning have led to the underrepresentation of transportation-disadvantaged individuals in the process and, thus, to automobile-oriented regions. Planning practices for small urban and rural areas especially, which often lack funding and other resources, have generally overlooked accessible pedestrian, bicycling, and multimodal infrastructure and facilities, resulting in underdeveloped and poorly connected networks. I conducted a social equity evaluation of the regional planning, investment prioritization, and programming processes for pedestrian and bicycling infrastructure using the case study of Monongalia County, West …
