This research identifies types of attitudes towards temporary street space reallocation measures on the neighborhood level to develop a better understanding of residents’ social acceptance and the underlying explanatory factors. Using a coding frame, interview notes with residents of two neighborhoods in Munich were qualitatively analyzed and grouped into types based on similar characteristics and combinations of characteristics. In-depth interviews were conducted later to refine the types and identify acceptance drivers and barriers. Seven types of attitudes emerged: the Car-Independent, the Car-Dependent, the Tree Advocates, the Public Space Enthusiasts, the Noise Sensitive, the Change Supporters, and the Status-Quo Satisfied. The types feature distinctive characteristics in terms of mobility behavior and preferences, openness towards a mobility transition, and public space-related needs and fears. Car dependency, car affinity, and the increase in recreational noise were identified as acceptance barriers. In contrast, introducing alternative mobility options, creating public spaces for interaction, and adding greenery were identified as acceptance drivers. Different types might have opposing perceptions of whether an intervention is “fair”. Targeted communication and participation processes proved to be relevant cross-type acceptance factors. Practitioners may benefit from such user-group specific insights to design more robust transformation strategies.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"30 ","pages":"Article 101370"},"PeriodicalIF":3.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143550861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The shipping industry is projected to grow on average at 2.1% annually for the next four years and is under enormous pressure from stakeholders and the International Maritime Organization (IMO) to curb GHG emissions to align with the Paris Agreement. The IMO strategy to cut GHG emissions from international shipping aims for a reduction of 20%, by 2030, and 70% by 2040, with respect to 2008 and achieve 100% reduction by 2050 to achieve net-zero emissions.

This study presents a sensitivity analysis for the Sustainable Public Transport Index for LATin AMerica (SPTI-LATAM) for 11 Latin American case study cities. Four weighting methods are applied at the levels of sustainability dimensions, categories and indicators, including the Equal Weighting Average (EWA), Analytic Hierarchical Processes (AHP), and Budget Allocation Points (BAP) approaches.

The study’s findings reveal substantial differences between the stakeholder preferences and the EWA approach. The highest weights are assigned to the <em>System Effectiveness</em> and the <em>Social</em> dimensions. Ranking positions are stable for cities with the highest sustainability performance, whereas those with lower performance are show greater sensitivity, which is related to a less balanced scoring of single indicators.

Alternative strategies to deal with uncertainty have been proposed in literature that are more focused on relations between decision-makers and exploring possibilities in an iterative way, such as shared visioning and other collaborative approaches. The question is how to stimulate actors to use these approaches in practice. This study tested how altering actor perspectives and views about uncertainty led to more collaborative responses to uncertainty. A comparison has been made in a serious game setting between a baseline control session, where uncertainty was negatively framed and rewarded, and an intervention session, where uncertainty was positively framed and rewarded. The game simulated a multi-actor decision-making process of negotiating about mobility innovations for a sustainable mobility plan. We found that in both sessions, actors used collaborative strategies to deal with uncertainty, but in the control session, participants were also applying control strategies for their own organization to reduce uncertainty because of the inhibiting conditions on mindset and synergy.
