The impact of transit-oriented development on housing prices in San Diego, CA

Dynamics of Transit Oriented Development, Role of Greenhouse Gases and Urban Environment: A Study for Management and Policy

The emission and mitigation of greenhouse gases transforms the status of urban environments. However, a policy accounting for all the aspects associated with transport is lacking. Problems related to transport include a greater reliance on cars, increased congestion, and environmental impacts. The absence of an efficient public transport system is a notable cause of the prompt escalation of diverse problems, for example, increases in the number of personal automobiles causes congestion on the road, resulting in air pollution, ubiquitous greenhouse effects and noise pollution, which ultimately affect human health. Transit oriented development (TOD) has been suggested as a solution to these problems. This paper reviews the impacts of transit development on urban development, greenhouse impact, the environment, economy, property value, travel behavior, and health etc., highlighting the policy issues which hinder TOD. Implementation of TOD has a strong impact on shaping the urban form, redevelopment, and the upgradation of old areas. Controlling transit phenomena will also help to control the emission and mitigation of greenhouse gases. This study will help in improving the urban environment and climatic condition of regions.

Transit-Oriented Development: Exploring Citizen Perceptions in a Booming City, Can Tho City, Vietnam

Transit-oriented development (TOD) is a crucial method for sustainable urban development and encouraging the use of public transit, especially for large densely populated cities such as Can Tho City, one of the top five cities in Vietnam. This study is aimed at identifying the factors which have a significant effect on the citizens’ engagement of public transport in the TOD environment. Based on the literature review and expert knowledge, 3 hypotheses related to citizens’ perceptions and citizen’s engagement are developed. A questionnaire was accordingly established using structural equation modeling (SEM). As a result, a total of 8 factors with 31 stems were obtained. The survey questionnaires were distributed to citizens of Can Tho City with 749 responses collected for KMO test Chi-square of 0.905. The analysis shows that all three hypotheses stand: (1) the citizens’ perception of local government’s capacity plays an important role in the citizens’ willingness to engage on public transport; the citizens’ perception of the usefulness of (2) TOD and (3) public transport has a positive influence on the engagement on public transport system. The major contribution of this study is that it can help other cities in developing countries to apply TOD.

Case-comparison study protocol for gauging effects of neighbourhood trends and sickness: examining the perceptions of transit-Induced gentrification in Prince George's County

INTRODUCTION

Impoverished neighbourhoods and communities of colour often bear the brunt of unintended transit-oriented development (TOD) impacts. These impacts have been known to come in the form of transit-induced gentrification (TIG), a socioeconomic by-product of TOD defined as a phenomenon that occurs when the provision of transit service, particularly light rail transit (LRT), 'up-scales' nearby neighbourhood(s) and displaces existing residents. Consequently, TIG or even the perception of TIG can impact health outcomes (eg, anxiety) and social determinants of health (SDOH) (eg, crime).

METHODS/ANALYSIS

In 2022, the purple line (PL), a 16.2 mile LRT line, is opening in Prince George's County, Maryland, a suburb of Washington, DC, comprised of over 80% African American and Hispanic residents. By taking advantage of this natural experiment, we are proposing the GENTS (Gauging Effects of Neighborhood Trends and Sickness: Examining the Perceptions of Transit-Induced Gentrification in Prince George's County) Study in order to evaluate perceived TIG and associated health outcome and SDOH changes, at two points in time, among Prince George's County adults in a prospective case-comparison design during the pre-PL LRT period. Descriptive analysis and latent growth curve modelling will be used to examine these changes over time.

ETHICS AND DISSEMINATION

Ethics approval has been granted by the University of Maryland Institutional Review Board. The GENTS Study will identify temporal changes in perceived TIG, health outcomes and SDOH among case and comparison residents before the completion and operation of the PL LRT, an under researched period of TOD. The dissemination of GENTS Study findings will be able to address research questions and policy issues that are specifically tailored to PG County while also providing more effective procedural solutions for other regions undergoing TOD and TIG risks.

Contradictions of Transit-Oriented Development in Low-Income Neighborhoods: The Case Study of Rosengård in Malmö, Sweden

Transit-oriented development (TOD) has become a leading model of urban planning worldwide that promises to meet a broad range of local and regional objectives: improving mobility, expanding ridership, attracting investment, reducing urban poverty, improving quality of life, making affordable housing and fostering urban integration. At the same time, the implementation of TOD in many cities has raised concerns about gentrification, displacement, re-segregation, and more polarization. This article aims to shed light on these issues by bringing together previously disparate literature that mentions these contradictions and discusses policymakers’ hopes and critics’ concern for the implementation of a newly started TOD project in a universal housing system in Rosengård—a segregated, low-income neighborhood in Malmö, Sweden. Although policy advocates view the project as a significant development strategy for a more sustainable Malmö, there are also real concerns about gentrification and the potential displacement of low-income residents. Furthermore, the mixed-methods study showes how integration might be achieved, but concerns have arisen about the possible exclusion of the current low-income residents, which brings up issues of inequality, representation of poverty, and marginalization.

Planning for urban life: A new approach of sustainable land use plan based on transit-oriented development

Transit-oriented development (TOD) is an integration of transportation systems with land use and has been given priority in sustainability strategies. However, most of the existing studies on TOD emphasize the economic and environmental perspectives of sustainability, paying little attention to social equity. Moreover, despite governments worldwide are gradually trying to address unsustainable issues associated with dramatic urbanization through a framework of TOD development, the improvement of land use planning necessary to achieve variegated sustainability within a safe trajectory is not being targeted or achieved. This paper aims to establish a framework of TOD planning in China's context that could be applied beyond the concept to planning experts and policymakers on how to integrate land use planning with TOD to achieve sustainability. We further applied an empirical study of Jiaomei, China to demonstrate the application of the designed framework. The study provided a new framework for understanding sustainable transportation development with land use management as applied to the urban planning process and for exploring new paths in practice toward sustainability.

The Color of Health: Residential Segregation, Light Rail Transit Developments, and Gentrification in the United States

As the modern urban-suburban context becomes increasingly problematic with traffic congestion, air pollution, and increased cost of living, city planners are turning their attention to transit-oriented development as a strategy to promote healthy communities. Transit-oriented developments bring valuable resources and improvements in infrastructure, but they also may be reinforcing decades-old processes of residential segregation, gentrification, and displacement of low-income residents and communities of color. Careful consideration of zoning, neighborhood design, and affordability is vital to mitigating the impacts of transit-induced gentrification, a socioeconomic by-product of transit-oriented development whereby the provision of transit service "upscales" nearby neighborhood(s) and displaces existing community members with more affluent and often White residents. To date, the available research and, thus, overall understanding of transit-induced gentrification and the related social determinants of health are limited and mixed. In this review, an overview of racial residential segregation, light rail transit developments, and gentrification in the United States has been provided. Implications for future transit-oriented developments are also presented along with a discussion of possible solutions.

Urban Structure, Subway Systemand Housing Price: Evidence from Beijing and Hangzhou, China

Using housing market data of Beijing and Hangzhou, China, we conduct a case study to detect how the difference of urban structure can affect the relationship between the subway system and housing prices. To quantify the characteristics of urban structure, we propose a constrained clustering method, which can not only reveal the spatial heterogeneity of the housing market, but also provides a link between heterogeneity and the underlying urban structure. Applying constrained clustering to Beijing and Hangzhou, we find that the relationship between accessibility to metro stations and housing prices is weak and vulnerable, while the improvement of commuting efficiency, measured by a key variable, the metro index, does have a robust connection to metro premium on housing units. In particular, only a large metro index can be associated with a positive metro premium. Structural features, such as the size of urban core and the existence of multiple sub-centers, influence the metro premium by affecting the value and spatial distribution of the metro index. The evidence from Beijing and Hangzhou supports that in a mono-centric city, the size of the urban core is positively associated with the metro index and the metro premium, while in a poly-centric city with a small urban core, the metro index tends to be lower in the core region and higher in the satellite regions, which enforces the metro premium to be negative in the core while positive outside of the core.

How Does Urban Rail Transit Influence Residential Property Values? Evidence from An Emerging Chinese Megacity

Urban rail transit (URT) plays crucial economic, social, and environmental roles and may generate positive externalities that can influence the residential property values (RPVs) in real estate markets. Little attention has been given to exploring the impacts with respect to both the spatial and temporal perspectives. This paper explores the impacts of URT on the RPVs of 480 gated communities with respect to the spatial and temporal dimensions using the hedonic price model and a panel data set from Zhengzhou for 2012–2016. The results show the following: (1) URT does have a significant positive impact on the RPVs in all the selected years from 2012 to 2016, and the influencing strength was a “U-shape” with the increased travel time to the nearest URT stations in most of the selected years. Specially, there is quite some interaction between the temporal and spatial dimensions. (2) The influencing strength of URT during its early stages of planning and construction was higher than that during the operation periods, which is quite different from previous research that uses these first-tier cities such as Beijing and Shanghai in China. (3) Regarding the operating period, the influencing strength reached its peak point after two years of the URT line operating. The results of this paper could provide some new ideas for policy-makers, real estate developers, and even the consumers in real estate markets.

Economic Impact of the High-Speed Railway on Housing Prices in China

This study investigated whether and to what extent does the High-Speed Railway (HSR) affect city-level housing prices. With the data of HSR operation and housing prices from 285 cities from 2009 to 2017, the paper aimed to estimate the quantitative relationship between HSR and city-level housing prices and exploited city and regional dummy variables to assess the disparities between regions, followed by the economic effects between typical city pairs. Our findings were as follows: (1) The introduction of HSR leads to a 13.9% increase in city-level housing prices, and the figures for national central cities and regional central cities were 31.7% and 19.6%, respectively; (2) regional imbalance was mitigated with the development of the HSR, and some central cities in underdeveloped regions were stimulated with regard to housing price growth; (3) siphon effects and diffusion effects were observed in megacity–small city pairs, while synergistic effects often lay in megacity–megacity pairs, and such effects all tended to be more significant with increases in the number of HSR lines and a drop in the travel time.

How will smart growth land-use policies affect travel? A theoretical discussion on the importance of residential sorting

Do policies to encourage compact, mixed use, pedestrian-friendly land-use patterns reduce driving? Not necessarily. Understanding how the built environment affects travel patterns is complex, not least because households may choose their neighborhoods on the basis of how they expect to get around. Some scholars have argued that ignoring this process of residential sorting, or ‘self-selection’, causes overestimates of built-environment influences and leads to false optimism about the efficacy of land-use policies in influencing travel. But others have suggested that residential self-selection provides a strong argument for using land-use policies to expand the supply of development that may facilitate lower automobile use. We argue that previous work on both sides of the argument has neglected to think through the myriad ways that residential choice could affect estimates of built-environment effects. In this paper we provide a more rigorous theory of residential self-selection, identifying a set of five household, market, and policy factors that are critical to understanding the residential self-selection problem, along with research questions that correspond to these factors. We explain why observed relationships between travel and the built environment could be misleading, causing either overestimates or underestimates, depending on the nature and context of residential choice. We illustrate with scenarios that show how different plausible assumptions about residential choice will bias, in different directions, estimates of the built environment's effects on travel; and we argue the need for research to focus not just on those independent estimates but, critically, upon the market and policy context that influences residential sorting.

The cost-effectiveness of installing sidewalks to increase levels of transport-walking and health

OBJECTIVE

This study investigated the cost-effectiveness of installing sidewalks to increase levels of transport-walking.

METHODS

Secondary analysis using logistic regression established the association of sidewalks with transport-walking using two transport-walking thresholds of 150 and 60 min/week using Western Australian data (n=1394) from 1995 to 2000. Minimum, moderate and maximum interventions were defined, associated respectively with one sidewalk, at least one sidewalk and sidewalks on both sides of the street. Costs, average and incremental cost-effectiveness ratios were calculated for each intervention and expressed as 'the cost per person who walks for transport for more than 150 min/week (60 min/week) after the installation of new sidewalks'. A sensitivity analysis examined the robustness of the incremental cost-effectiveness ratios to varying model inputs. Costs are in 2012 Australian dollars.

RESULTS

A positive relationship was found between the presence of sidewalks and transport-walking for both transport-walking thresholds of 150 and 60 min/week. The minimum intervention was found to be the most cost-effective at $2330/person and $674/person for the 150 and 60 min/week transport-walking thresholds respectively. Increasing the proportion of people transport-walking and increasing population density by 50% improved the cost-effectiveness of installing side-walks to $346/person.

CONCLUSIONS

To increase levels of transport-walking, retrofitting streets with one sidewalk is most cost-effective.
