Resilience is the ability of a system to adapt, persist, and transform as a reaction to threats, which may be external or internal to the system, while vulnerability is the state of being susceptible to harm from exposure to stresses associated with environmental and social change and from the inability to adapt. Based on a study of the threats that can affect urban mobility, we identified a gap regarding the analysis of the levels of resilience and vulnerability in the face of subsidy threats that can severely affect developing countries. This article measures the level of resilience and vulnerability due to the absence of public transport fare subsidies. For this purpose, we developed an approach based on fuzzy logic and applied it in 33 administrative regions (ARs) of the city of Rio de Janeiro, Brazil. We obtained four matrices of the levels of vulnerability and resilience of each of the regions as an origin and destination. The results show that areas nearest to the downtown region and those with high-capacity transportation available (commuter train and/or subway, systems with many transfer points) are more resilient, while a high level of vulnerability is associated with low income, negative socioeconomic indicators, and the predominance of road transportation to reach jobs. The contribution of this paper is the method applied to analyse the levels of vulnerability and resilience of public transport, which includes a threat that can cause a rupture that impacts routines and job accessibility in a region.

Long-term scenarios for mobility within cities usually neglect the energy supply challenge and how the implied risks affect urban mobility services. High levels of private transport and fossil fuel dependency tend to prevail in urban agglomerations of modern cities in many parts of the world. The resilience approach supports a new perspective on transportation solutions, not only based on how to consume less energy or emit less CO², but how vulnerable urban mobility is in face of a fossil threat. This paper aims to assess the vulnerability of urban mobility in the face of fossil fuel threats under a social and geographical scope. We apply a case study with the city of Rio de Janeiro, confronting city inhabitants with a price increase of gasoline and oil-based public transportation. We found that more than 50% of the districts of Rio de Janeiro presents low-medium or low level of resilience of urban mobility. Furthermore, they are in areas with lower accessibility to metro stations and more citizens with reduced income levels.

Public transport systems that ensure safe and efficient mobility are essential to promote sustainability in cities. However, public transport is susceptible to violence. Additionally, men and women have distinct perceptions of security, which can lead to different reactions in the face of danger. Therefore, considering this situation from a gender perspective, the goal of this study is to assess the levels of resilience in trips made by public transport users when exposed to violence. Data were collected from 763 individuals (women: 60.8%; men: 39.2%) within the academic community of a university campus in Rio de Janeiro, Brazil, through an online questionnaire. The information obtained included the participants’ socioeconomic details, security perceptions, and changes in travel patterns due to security concerns. The results of the Cronbach’s alpha test (0.842) indicated a good internal consistency within the data. Chi-squared tests of independence were applied, and calculations for effect size measures were conducted to evaluate the possible association between gender and other variables. Regarding the level of resilience of the trips made, evidence was found that the perception of safety and the behavior of public transport users are influenced by their gender. Regarding the gender of the respondents, an association was found with the resilience levels of trips. Furthermore, it was found that women are more vulnerable to violence in public transport than men, with risks of feeling unsafe during walks to or from stations and on buses being 1.1 and 1.5 times higher, respectively. Additionally, it was observed that the behavior of public transport users is significantly influenced by past victimization experiences, prompting measures for greater protection to be sought. The results of this study allow for a better understanding of how men and women feel exposed to violence when using public transport and can contribute to the creation of public policies to promote safety. Additionally, they can assist security authorities in directing and concentrating police efforts more effectively.

The city of Valparaíso, Chile, faces significant mobility challenges due to its steep slopes, complex urban infrastructure, and socioeconomic conditions. In this direction, this study explores the potential promotion of E-bike uses by identifying the optimal routes that connect metro stations to strategic hilltop streets in the city. A hybrid methodology combining a multicriteria GIS-based analysis and an experimental study was used to evaluate potential routes and the possibility of increasing the power limitations for non-motorized mobility in Chile. Fifteen routes were assessed based on criteria including the slope, traffic safety, directionality, intersections, and travel distance. The results indicate that routes such as Cumming from Puerto and Bellavista stand out as the most viable for e-bike use given their favorable characteristics. The experimental study revealed that higher-powered E-bikes (500 W and 750 W) would be more able to overcome the steep slopes of Valparaíso, with an average speed of 5.36 km/h and 9.52 km/h on routes with a 10.88% average slope. These findings challenge the current regulatory limit of 250 W for non-motorized vehicles in Chile, highlighting the potential benefits of increasing their power limits to enhance sustainable mobility in the hilly urban contexts of this country. This study highlights the need to adapt urban mobility policies to the unique topographical conditions of each city. Future research should build upon more experimental studies, develop specific street-scale analyses using audit methods, incorporate climate-related variables, and evaluate the economic viability of e-bike infrastructure. Addressing these aspects could position Valparaíso as a leading example of sustainable urban mobility for cities facing comparable challenges.

Social sustainability is a dimension of the concept of sustainability that has gained importance only in the last few decades and can be identified as the pursuit and measure of social equity. Equity can be analyzed under two approaches: horizontal and vertical. The horizontal approach considers the distribution of benefits equally, while the vertical equity considers these same benefits, but between specific groups, which is an adequate approach when dealing with policy-related topics, such as tariff subsidy. Accessibility is a factor that contributes to urban social sustainability and it may be a representation of physical and/or social barriers in the urban environment. Thus, this paper aims to assess social sustainability under a vertical equity approach, based on accessibility to jobs, for different population groups, comparing public with individual motorized transport. The case study was carried out in Medellín-Colombia, using data from the 2017 Home Destination Survey. It was found that users of individual transport have access to a greater number of jobs than users of public transport. In addition, those with higher income have better accessibility than those with lower income, even though they are not beneficiaries of tariff subsidy policies. Another highlight is that areas closer to the central region are also more accessible. In some specific communes, it would be indicated to seek to improve access through public transport, or the implementation of some public policy at the municipal level that could have an impact on access to opportunities.

Current study provides a performance measurement system (PMS) based on Supply Chain Operations Reference (SCOR) adapted for the service sector. A systematic literature review was conducted on 16 performance measurement systems, which included 44 performance indicators and various performance metrics. Performance indicators and metrics were sorted according to conceptual similarities and then related to the five management processes intrinsic to SCOR model (plan, source, make, deliver and return). Indicators researched in a review of the literature were classified into six groups, namely, financial, velocity, sustainability, quality, resource utilization and customer services. The proposed PMS fills a gap in literature by forwarding a tool for the evaluation of the supply chain performance within the service sector.
