Abstract

Lack of clarity about what ‘healthy’ urban development means, alongside financial and technical challenges, has slowed progress on health-promoting development. Case studies could support learning, however, scholars have been critical of their risks when they are applied without adequate consideration of required adaptations or alternatives. We explored how health is promoted through new development via a narrative synthesis of published cases and critically evaluated their value. Cases more frequently achieved sustainability goals than equity and inclusion goals. We conclude that case studies have particular value when shared in a manner that encourages critical examination and discussion, such as through storytelling.

Abstract

Climate change is making disaster events more frequent and intense, increasing the risk to economic security, ecosystem health, and human health and well-being. Hazard mitigation planning, overseen in the United States by the Federal Emergency Management Agency (FEMA), aims to reduce disaster risk by identifying hazards and taking action to reduce their impact. While FEMA policy requires states and territories to consider the risks of climate change in their plans, guidance remains broad. As a result, jurisdictions have taken different approaches to integrating climate change into their hazard mitigation plans (HMPs). Thirty of 56 U.S. State and Territorial Hazard Mitigation Officers (SHMOs) responded to a survey concerning climate planning, building on a similar survey conducted in 2018. A majority of respondents recognized that their jurisdictions are vulnerable to climate change and agreed that climate change is a threat to their jurisdictions both now and in the future. Respondents were motivated to integrate climate change into their HMPs by factors including increased evidence for climate change projections and disaster events in either their jurisdictions or neighboring ones. Among the most frequently reported barriers was reliance on historical patterns of hazard exposure. Most respondents had incorporated at least one climate change adaptation strategy into their HMPs but reported having insufficient resources to plan for and implement climate-related hazard mitigation activities. Findings suggest that state and territorial hazard mitigation planning programs are taking more steps to integrate climate change into their plans and that SHMOs are more aware of the risks that climate change poses than in 2018. Further research is needed to explore how best to support state-level hazard mitigation program response to climate change.

Equity issues associated with the widespread implementation of autonomous vehicles

Abstract

Autonomous vehicles (AVs), either shared or privately owned, are predicted to become a common transport mode used by the general population in coming decades. Policies governing the use of AVs may increase or decrease social inequities. This review synthesizes existing literature and provides policy recommendations to enhance equity as the use of AVs becomes more widespread. We identified nine areas in which AVs could impact equity: (i) assessment of community mobility needs and priorities, (ii) education and outreach, (iii) disparities in infrastructure quality, (iv) equitable distribution of customer services, (v) access to AVs by persons with low incomes, (vi) shared infrastructure services, (vii) barriers to shared AV use, (viii) access to AVs by persons with disabilities and (ix) disruption of existing transportation jobs. Recommendations for promoting equitable use of AVs include (i) policies governing how jurisdictions oversee AV implementation and (ii) policies addressing how jurisdictions issue permits to AV service providers. Oversight policies include ensuring input from disadvantaged communities, providing subsidies for low-income users, establishing ride-sharing rules to protect vulnerable populations, reviewing the equity implications of proposed AV infrastructure improvements, providing retraining opportunities for those who may lose jobs due to AV implementation and monitoring the impact of AV policies implemented. Permitting processes include ensuring equitable access to AVs for low-income, minority, and older users and persons with disabilities, ensuring equitable distribution of AV service areas and verifying that data from all communities are incorporated into the artificial intelligence algorithms used to guide AVs.

Abstract

Sidewalks are a critical but underresourced part of our transportation system. Despite their importance in promoting equity, health, and safety, sidewalk networks are often underfunded and municipalities may have little information about their condition. We conducted a document review, informant interviews, and a descriptive study of 21 selected U.S. cities to compare practices for conducting sidewalk inventories and their use for improving municipal sidewalk networks. Although diverse in geography, population size, density, and median household income, the selected cities represent a sample of convenience and not a random sample of U.S. cities. The results suggested that compliance with the Americans with Disabilities Act is a primary motivator for conducting sidewalk inventories and the cost of conducting an inventory is not prohibitive. Inventory methods included walking each sidewalk segment using handheld devices, LIDAR mounted on wheeled vehicles, and aerial photography, with data uploaded to geographic information system databases. Sidewalk inventories can be used to promote equity by increasing the percentage of city streets that have sidewalks. Areas for future study include developing better cost estimates for each type of sidewalk inventory method, examining the legal implications of sidewalk inventories, and estimating the incremental health benefits obtained for each additional investment in sidewalk construction and repair.

Economic impact on local businesses of road safety improvements in Seattle: implications for Vision Zero projects

Abstract

Background Local transportation agencies implementing Vision Zero road safety improvement projects often face opposition from business owners concerned about the potential negative impact on their sales. Few studies have documented the economic impact of these projects.

Methods We examined baseline and up to 3 years of postimprovement taxable sales data for retail, food and service-based businesses adjacent to seven road safety projects begun between 2006 and 2014 in Seattle. We used hierarchical linear models to test whether the change in annual taxable sales differed between the 7 intervention sites and 18 nearby matched comparison sites that had no road safety improvements within the study time frame.

Results Average annual taxable sales at baseline were comparable at the 7 intervention sites (US$44.7 million) and the 18 comparison sites (US$56.8 million). Regression analysis suggests that each additional year following baseline was associated with US$1.20 million more in taxable sales among intervention sites and US$1.14 million more among comparison sites. This difference is not statistically significant (p=0.64). Sensitivity analyses including a random slope, using a generalised linear model and an analysis of variance did not change conclusions.

Discussion Results suggest that road safety improvement projects such as those in Vision Zero plans are not associated with adverse economic impacts on adjacent businesses. The absence of negative economic impacts associated with pedestrian and bicycle road safety projects should reassure local business owners and may encourage them to work with transportation agencies to implement Vision Zero road safety projects designed to eliminate traffic-related injuries.

Abstract

Objectives: We established a community–academic–policy partnership to examine mobility challenges and opportunities by centering members of a diverse South Seattle neighborhood.
Methods: Three participatory research methods were used: (a) 30- to 60-min qualitative interviews with community leaders (n = 12) and members (n = 16); (b) a photovoice with youth (n = 10); and (c) mobility audits. We also engaged extensively in community dissemination and advocacy.
Results: Four major themes emerged: experiences with the built environment; conflicting views on promoting active transportation; experiences of danger, violence, and racism while moving in the community; and pride and connections within the community. Mobility audit findings reinforced many community member messages about needed infrastructure changes. Participants consistently expressed the need for neighborhood and city-wide structural improvements to support transportation and mobility, including enhanced public transportation; better lighting, crosswalks, sidewalks, pavement, and curb cuts; and maintenance of a neighborhood mixed-use trail. Participants shared the importance of community connection while walking, rolling, or using public transit and wanted to maintain this experience.
Conclusions: Collectively, findings identified ways to increase nonmotorized transportation and public transit access, safety, and resilience, centering solutions on communities of color. We disseminated and amplified community recommendations to advance mobility justice in South Seattle via a community forum, developing a website, holding meetings with local leaders, and writing through print and electronic media. A key, novel strength of our project was the addition of community organizations, community–academic partners, and government leaders from the project’s inception. Local leaders should engage in mobility justice-focused community engagement to advance equity.

Abstract

Understanding the carbon dynamics of the transportation sector is necessary to mitigate global climate change. While urban scaling laws have been used to understand the impact of urban population size on carbon efficiency, the instability of these scaling relationships raises additional questions. Here, we examined the scaling of on-road transportation carbon emissions across 378 US metropolitan statistical areas (MSAs) using diverse urban landscape patterns and spatial units, from the MSA level down to 1 km grid cells. Beginning with a baseline scaling model that uses only population size, we expanded the model to include landscape metrics at each spatial scale based on correlation results. We found that: (1) urban landscape characteristics provide insights into carbon mechanisms not fully captured by population size alone, (2) the impact of population size on on-road carbon emissions transitions from linear to sub-linear scaling relationships as the geographic scale of analysis decreases, and (3) clustered urban developments can form carbon-efficient landscapes, while fragmented urban areas tend to be carbon-inefficient. Based on empirical evidence, this research advocates for hierarchical spatial planning and supports the implementation of policy measures aligned with smart growth principles to mitigate carbon pollution.
