especially given the increasing numbers of residents choosing to bike and walk. Sharing
the roads with automobiles, these alternative road users are particularly vulnerable to
sustain serious injuries. With this in mind, it is important to identify the factors that
influence the severity of bicyclist and pedestrian injuries in automobile collisions. This
study uses traffic collision data gathered from California Highway Patrol’s Statewide
Integrated Traffic Records System (SWITRS) to predict the most important
determinants of injury severity, given that a collision has occurred. Multivariate binomial
logistic regression models were created for both pedestrian and bicyclist collisions, with
bicyclist/pedestrian/driver characteristics and built environment characteristics used as
the independent variables. Results suggest that bicycle infrastructure is not an important
predictor of bicyclist injury severity, but instead bicyclist age, race, sobriety, and speed
played significant roles. Pedestrian injuries were influenced by pedestrian and driver age
and sobriety, crosswalk use, speed limit, and the type of vehicle at fault in the collision.
Understanding these key determinants that lead to severe and fatal injuries can help
local communities implement appropriate safety measures for their most susceptible
road users.
This project was inspired by Dr. Kelli L. Larson’s research which disproved three common landscaping misconceptions in the Phoenix Valley. The first misconception states that newcomers, not long-time Phoenicians more often have and prefer grassy lawns instead of xeric, desert-adapted landscapes when actually the opposite is true. Secondly, the rise in xeric landscapes is not due to personal choice but rather a variety of other factors such as developer decisions. Finally, Dr. Larson’s research also disproves the assumption that people who possess pro-environmental attitudes correspondingly demonstrate sustainable landscaping behavior, and finds that people with those attitudes actually tend to irrigate more frequently in the winter months. Debunking these misconceptions is important because the long-term impacts of global climate change could have effects on water use in the desert southwest, and promoting water conservation in urban residential landscaping is an important step in the creation of sustainable water use policy. <br/><br/>The goal of my project was to make this information more accessible to broader public audiences who may not have access to it outside of research circles. I decided to create a zine, a small batch, hand-made mini-magazine, centered around disproving these myths so that the information could be distributed to broader audiences. I conducted informal stakeholder interviews to inform my design in order to appeal to those audiences, and constructed a 16-page booklet which debunked the myths and encouraged critical thinking about individual water use and urban landscaping habits. The zine included hand-painted illustrations and was constructed as a physical copy with the intention of eventually copying and distributing both a physical and digital version. The purpose of this project is to create a way of accessing reliable information about urban landscaping for residents of the Phoenix Valley, where the climate and geography necessitate water conservation.
Much of modern urban planning in the United States is concerned with making cities more walkable. However, this is occurring as the urban landscape of the U.S. is altered radically by changes in crime patterns after the summer of 2020. This paper seeks to find out what the relationship is between walkability and crime in major U.S. cities after 2020. Using multiple linear regressions at the city and neighborhood scale, walkability is found to be a significant, positive predictor of 2019 violent crime rate, 2020 violent crime rate, 2020 property crime rate, and 2020 total crime rate at the city level. It was found to be a positive, but not significant predictor at the neighborhood level. Walkability has no protective influence against crime/rising crime, and it appears that as crime gets worse it tends to get worse in the cities that are more walkable, but other variables such as African American population are better determinants of crime. Urban planners should seek to increase walkability while also finding a way to mitigate potential exposure to crime.
