Developing Strategies To Enhance Mobility And Accessibility For Community-Dwelling Older Adults, Kate Hyun, Kathy Lee, Caroline Krejci, Nilufer Oran Gibson, Troyee Saha

TREC Final Reports

Mobility disparities among older adults affect their ability to travel and access services. This project seeks to understand challenges, barriers, and gaps that older adults experience, and develop forms of assistance or educational strategies to fill the varying mobility gaps and meet mobility needs. This study characterizes older adults’ use of existing and potential transportation options, including conventional transit, paratransit, and ride-hailing systems, based on surveys collected from 146 low-income older adults in Dallas, TX. Using the survey data and interview data, we develop two mathematical modeling (a Latent Class Cluster Analysis and agent-based modeling (ABM)) and conduct content analysis …

Lifelong Instability And Perceived Risk Of Future Homelessness In Older Adults, Sarah Dys, Anna Steeves-Reece, Paula Carder

Institute on Aging Publications

Housing has long been considered a social determinant of individual and population health. Older adults with low incomes face several challenges to maintaining stable, affordable housing. Using data from a previous explanatory study of older adults waitlisted for housing assistance (n = 267), we explore individual characteristics and themes associated with older adults’ perceived housing instability and risk of future homelessness. This mixed-methods study identifies salient themes of financial insecurity, age discrimination, employment and health, interpersonal relationships, and trauma. Our analysis and findings highlight experiences of instability over the life course related to older adults’ current housing circumstances.

Urban Studies and Planning Faculty Publications and Presentations

Active transportation (AT) is widely viewed as an important target for increasing participation in aerobic physical activity and improving health, while simultaneously addressing pollution and climate change through reductions in motor vehicular emissions. In recent years, progress in increasing AT has stalled in some countries and, furthermore, the coronavirus (COVID-19) pandemic has created new AT opportunities while also exposing the barriers and health inequities related to AT for some populations. This paper describes the results of the December 2019 Conference on Health and Active Transportation (CHAT) which brought together leaders from the transportation and health disciplines. Attendees charted a course …

Resilience And Urban Regeneration Policies. Lessons From Community-Led Initiatives. The Case Study Of Canfugarolas In Mataro (Barcelona), Diego Saez Ujaque, Elisabet Roca, Rafael De Balanzó Joue, Pere Fuertes, Pilar Garcia-Almirall

Publications and Research

This paper addresses socio-ecological, community-led resilience as the ability of the urban system to progress and adapt. This is based on the socio-cultural, self-organized case study of CanFugarolas in Mataró (Barcelona), for the recovery of a derelict industrial building and given the lack of attention to resilience emerging from grassroots. Facing rigidities (stagnation) observed under the provisions of urban regeneration policies (regulatory realm), evidenced in the proliferation of urban voids (infrastructural arena), the social subsystem stands as the enabler of urban progression. Under the heuristics of the Adaptive Cycle and Panarchy, the study embraces Fath’s model to analyze the transition …

Focus On Sustainable Cities: Urban Solutions Toward Desired Outcomes, M. Georgescu, M. Arabi, Winston T. L. Chow, E. Mack, K. C. Seto

Research Collection School of Social Sciences

Urbanization represents the single most impactful and long-lasting transformation of the Earth system since the dawn of civilization. Cities are simultaneously locations of innovation, social connectivity, and wealth, but they also create local-to-global environmental degradation and socioeconomic disparities. For example, food provision for cities has required significant land-use change and fertilizer input, has altered regional climate, biogeochemical cycles, and degraded marine and landscapes through biodiversity loss, algal blooms and fish kills. To maintain urban livelihoods and the provision of goods and services, cities require vast amounts of energy (e.g. to provide access to transport, cooling systems), which are massive producers …

Data From: “Developing Strategies To Enhance Mobility And Accessibility For Community-Dwelling Older Adults”, Kate Hyun, Kathy Lee, Caroline Krejci

TREC Datasets and Databases

This study administered a survey to 146 lower-income adults in Dallas, TX, aged 55 and older, between February and June 2020. As affordable public transportation options target senior citizens age 65 and older, this study focused on older adults as aged 65 and over. However, we also recruited adults aged 55 to 64 to distinguish how emerging seniors differently perceive or perform transportation activities compared to current older adults. In a partnership with a local organization providing resources and information for older adults and family caregivers located in Dallas, we used snowball sampling by recruiting participants from Foster Grandparent Program …

Improving Mobility And Quality Of Life For Older Adults, Kate Hyun, Caroline Krejci, Kathy Lee

TREC Project Briefs

As we get older, transportation provides a vital link between home and community. Without reliable and easy ways to get around, many older adults (especially those who live alone) have limited access to essentials like groceries and medicine, let alone social interaction. A new report from the University of Texas at Arlington (UTA), Developing Strategies To Enhance Mobility And Accessibility For Community-Dwelling Older Adults, looked at the mobility challenges, barriers, and gaps that older adults experience, with an eye toward developing forms of assistance or educational strategies to fill those gaps.

Development Of Intelligent Multimodal Traffic Monitoring Using Radar Sensor At Intersections, Siyang Cao, Yao-Jan Wu, Feng Jin

TREC Final Reports

Multimodal traffic monitoring is critical for improving mobility and safety at intersections with potential conflicts among various modes of transportation. Traditional traffic monitoring approaches utilizing cameras cannot work reliably during the night and under hazardous weather conditions. We propose to build a new intelligent multimodal traffic monitoring device using the low-cost mmWave radar. The proposed device can reliably distinguish different modes (such as buses, pedestrians, bicyclists, trucks, motorcycles, etc.), and determine the counts, speed, and moving directions of every single target in an urban environment under various lighting and weather conditions. In the study, a low-cost prototype system will also …

Urbanization Policy And Economic Development: A Quantitative Analysis Of China's Differential Hukou Reforms, Wen-Tai Hsu, Lin Ma

Research Collection School Of Economics

The household registration system (hukou system) in China has hampered rural-urban migration by posing large migration friction. The system has been gradually relaxed in the past few decades, but the reforms have been differential in city size. We find a striking contrast in migration patterns between years 2005 and 2015; rural people tended to move more to large cities in 2005, but more to small- and medium-sized cities in 2015. We calibrate a spatial quantitative model to the world economy in both years with China divided into rural, mega-city, and other-city regions. We find that alternative urbanization policies that are …

Using Fuzzy Clustering Of User Perception To Determine The Number Of Level-Of-Service Categories For Bus Rapid Transit, Yueying Huo, Jinhua Zhao, Xiaojuan Li, Chen Guo

Journal of Public Transportation

The concept of level of service (LOS) is meant to reflect user perception of the quality of service provided by a transportation facility or service. Although the LOS of bus rapid transit (BRT) has received considerable attention, the number of levels of service of BRT that a user can perceive still remains unclear. Therefore, in this paper, we address this issue using fuzzy clustering of user perception. User perception is defined as a six-dimension vector of the perceived arrival time, perceived waiting time, bus speed perception, passenger load perception, perceived departure time, and overall perception. A smartphone-based transit travel survey …

Transantiago, the public transport system implemented in Santiago, Chile, remains a controversial subject of public debate due to constantly increasing fare evasion rates throughout its decade-long existence. The research question under consideration in this paper is as follows: What motivates individuals to evade or pay bus fares? To answer this question, we developed a multidisciplinary study that combined relevant engineering expertise with a sociological perspective and combined quantitative analyses with qualitative methodologies …

Validating The Resident View In Long-Term Care Settings: Final Report To Oregon Department Of Human Services, Aging & People With Disabilities Division, Diana L. White, Ozcan Tunalilar, Serena Hasworth, Jaclyn Winfree, Institute On Aging, Portland State University

Institute on Aging Publications

In 2015, Portland State University Institute on Aging (PSU/IOA) received a grant from the Quality Care Fund to develop the Resident VIEW (Voicing Importance, Experience, and Well-being), a measure of person-centered care (PCC) from the perspective of residents. Structured open-ended interviews were conducted with residents living in nursing homes (NH), assisted living (AL/RC), and adult foster homes (AFH) settings to learn more about their everyday concerns, values, and preferences. Each interview focused on one of eight domains of PCC. These domains had been identified from the literature and in prior research. Personhood, or as described by residents as being “treated …

TREC Webinar Series

Drawing from the framework of social determinants of health, the objective of this study is to investigate the cross-sectional association between transportation-related factors and self-perceived physical health among adults in the U.S.

Data for this study were derived from the 2017 National Household Travel Survey. An analytic sample of 71,235 respondents aged 18 and 64 years was analyzed using binary logistic regression. Of the 71,235 respondents examined, 8.9% perceived their physical health to be poor. About 36% of the respondents had fewer vehicles per individuals in the household.

Controlling for the effects of other factors, respondents who had fewer vehicles …

An Assessment Of Bicycle Detection Confirmation And Countdown Devices, Christopher Monsere, Sirisha Kothuri, David S. Hurwitz

PSU Transportation Seminars

For a person on a bicycle at intersections, trail crossings, or midblock locations that are signalized, knowing that they have been detected and how long they must wait to receive a green indication is valuable information. This presentation will summarize the findings from the online survey (1,048 responses), observed behaviors (2,428 persons on bicycle), and an intercept survey ( 234 persons) to understand blue light feedback devices and countdown timers at signalized intersections.

Findings suggest that the design where the blue light was embedded in the sign was more visible to cyclists and observed by higher proportions of cyclists in …

Impacts Of Automated Vehicle Technologies On Future Traffic, Xiaowei Shi

USF Tampa Graduate Theses and Dissertations

Recently manufactured commercial vehicles are increasingly equipped with automated driving features. The adaptive cruise control (ACC) system, arguably the most common automated vehicle (AV) driving feature, is available on many new models of commercial vehicles in recent years. The ACC system is composed of a series of onboard sensors (e.g., millimeter-wave radars), computing and control units, which enables the commercial AVs to automatically maintain a safe headway between the subject AV and the lead vehicle by dynamically control the AV speed with real-time sensor information. Note that such commercial AVs are controlled by exact, prescriptive, and fast-responding computer-mechanical dynamic models …

Efek Aglomerasi Di Indonesia : Komparasi Jawa Dan Luar Jawa, Eggie Dwi Ananda Chaniago, Muhammad Hanri

Jurnal Kebijakan Ekonomi

Population density and average city’s wages in Java are higher than outside Java. The literature shows that population density can increase the productivity of firms and workers, thereby increasing the level of wages in cities. In urban economics, agglomeration economies are defined as the benefits that come when firms and people locate near one another together in cities and industrial clusters. This study estimates the agglomeration effect in Java and outside Java cities by analyzing the relationship between population density and urban characteristics with wage levels. Previous studies have shown that population density is positively correlated to wage levels at …
