Apresenraçao: Abordagem Territorial das Mudanças Climáticas e Fontes Móveis de Poluição

2025-07-11T13:00:37+00:00

A intensificação dos efeitos das mudanças climáticas impõe novos desafios às políticas públicas e à governança territorial. Podemos, inclusive, afirmar que o tema é o maior desafio coletivo para a continuidade da sociedade. No centro dessas transformações está o setor de transportes, responsável por parcela significativa das emissões globais de gases de efeito estufa (GEE), especialmente no que tange às chamadas fontes móveis de poluição — veículos automotores utilizados para transporte de pessoas e mercadorias.

Analysis of the Influence of Pavement Type on Vehicular Pollutant Emissions.

2025-07-10T18:28:46+00:00

Air pollution has become a significant environmental challenge in modern times, with a substantial portion of atmospheric emissions originating from the transportation sector, particularly road transport. Numerous factors can influence the emission levels of vehicular gases, ranging from vehicle characteristics and driving behavior to the condition of road infrastructure. This study aims to investigate the impact of road pavement surfaces (concrete and asphalt) on vehicular air pollutant emissions. To conduct this research, Portable Emission Measurement Systems (PEMS) were utilized for collecting vehicle gas emission data. The analysis involved employing the ANOVA test to compare the emission averages of CO2, CO, and NOx. Our findings revealed that average NOx emissions were lower on concrete pavements, but no significant differences were observed in CO2 and CO emissions between both pavement types. Understanding the influence of different pavement surfaces on vehicular gas emissions can contribute to urban planning and the formulation of policies aimed at mitigating air pollution. These findings underscore the importance of considering road infrastructure as a potential factor in managing environmental impacts caused by the transportation sector.

Simulação de estratégias para descarbonização do transporte de cargas

2025-07-10T18:28:46+00:00

Freight transport is a source of greenhouse gas emissions. Its decarbonization is challenging due to the high dependence on fossil fuels and increasing demand. This paper analyzes the dynamics of the freight decarbonization policies. System Dynamics stands out for its suitability to investigate the impact of policies over time. A simulation model was developed and applied to the Brazilian freight system to analyze the implementation time and impact of policies toward alternative means of transportation, such as modes and fuels. Significant emissions reduction is possible by combining a noteworthy shift from roadways to alternative modes, in addition to zeroing out the use of diesel. The emission budgets for the Brazilian freight sector to limit global warming to 1.5ºC or 2ºC would be reached in the next years, which corroborate the urgency for more forceful actions to promote freight decarbonization.

Climate Justice in Climate Action Plans: An Analysis of the Transport Sector

2025-07-10T18:28:47+00:00

To address climate challenges, Brazilian municipalities have been developing their Climate Action Plans (PLACs). However, there is no standardized regulatory or methodological framework to guide the formulation of these plans, leading to heterogeneous approaches that are often misaligned with fundamental principles of climate justice. The absence of unified criteria hinders the assessment of PLACs' adequacy in the context of urban transport—a critical sector both in terms of pollutant gas emissions and socio-environmental impacts. This challenge is further compounded by the need to ensure that the burden of climate change does not disproportionately affect the most vulnerable populations. Thus, this study aims to propose an index that assesses the adequacy of PLACs in advancing climate justice within the transport sector. The proposed index can guide decision-makers in evaluating the effectiveness of existing measures and identifying the need for new initiatives. To achieve this, the transport-related content of PLACs from ten Brazilian cities was analyzed. Furthermore, strategies aimed at enhancing climate justice in the transport sector were prioritized using a multi-criteria analysis. These strategies include emission reduction, access to opportunities, education and social participation, development of resilient transport systems, implementation of sustainable infrastructure, and air quality monitoring. A questionnaire was administered to experts in the field to determine the weighting of these measures and strategies. The predominant strategies identified in PLACs involve expanding public transport fleets with electric or lower-emission vehicles and improving both public and active transportation. The results indicate that the mitigation measure that contributes most to climate justice is the integration of socio-cultural aspects and social participation. Conversely, among adaptation measures, prioritizing sustainable infrastructure was identified as the most significant. Finally, the municipalities of Rio de Janeiro (0.737) and João Pessoa (0.632) achieved the highest index scores.

O sistema de transporte tem sido um dos principais contribuintes para o avanço e intensificação da poluição do ar. Este estudo investigou os efeitos do ajuste da velocidade regulatória nas emissões de poluentes veiculares em vias urbanas, com foco em . Os dados foram coletados em uma avenida em Fortaleza, Ceará, Brasil, antes e depois do ajuste da velocidade de 60 para 50 km/h, usando tecnologia embarcada nos veículos. As análises dos cenários foram ex-ante e ex-post, e os resultados sugeriram que após a redução da velocidade para o período de tráfego menos intenso do dia, houve um impacto significativo na redução das emissões médias em 7,2%. Esses achados indicam que o ajuste da velocidade regulatória nas vias urbanas pode contribuir como parâmetro norteador para decisões e estratégias de planejamento de tráfego, com ênfase na melhoria da qualidade do ar local e na redução do número de mortes e Doenças Crônicas Não Transmissíveis (DCNT) na saúde humana. .

The key actors map: a novel tool for transport accidents investigation

2025-07-10T18:28:47+00:00

The article presents a novel tool for transport accidents investigation: the key actors map (MAC). The MAC offers significant advantages for investigation teams, as it allows them to quickly understand the panorama of an event and the identification of organizations and individuals involved. Consequently, the MAC facilitates data acquisition and accident analysis. Working with MAC helps to understand who (and how) can contribute or hinder the achievement of accident investigation objectives: transform the situation under study, prevent new events, strengthen safety and, finally, improve the performance of the transportation system. With this objective, firstly, some key notions will be introduced, then the purposes and advantages of MAC will be defined and, finally, how to prepare a MAC will be explained and an example will be presented.

Sectional evaluation of free student passes: impacts on gender, education and type of institution.

2025-07-10T18:28:48+00:00

This study aims to understand the impacts of the Student Free Pass in Maceió-AL. The work focuses on three aspects to demonstrate this impact: a) it shows the legal instruments that deal with the public policy of the Student Free Pass in the municipality, which regulate the conditions, parameters and standards for the student to have access to the right, b) analyses data generated by electronic ticketing from the period between 2016 and 2023 in order to identify the general usage behaviour of users, focusing on students and c) studies the variation in the number of student registrations considering demographic characteristics such as gender, level of education and distribution between public and private educational institutions. The results show increases in student boarding’s causing the share of student users to almost double. The expansion occurred for all levels of education, and more markedly among female students and students from public institutions, which shows that the zero student tariff policy contributes to promoting social inclusion, improving equal opportunities and expanding the access to the Public Collective Transport system, especially for the most vulnerable population.

Evaluación del riesgo de una intersección vial en Ciudad de México con enfoque semiótico a través de los dispositivos para el control de tránsito

2025-07-10T18:28:48+00:00

Roads are an important part of cities' infrastructure; Its objective is to facilitate the movement of people efficiently and safely. However, in urban centers like Mexico City this is not the case, because despite the existence of road codes that regulate and control the mobility of vehicles and pedestrians on public roads, the roads have become a social problem, since traffic accidents claim thousands of lives each year.

In 2018, a study was concluded from a semiotic perspective related to signaling and traffic incidents at road intersections. The objective of the research was to determine the degree to which Traffic Control Devices -DCT- (signals) were related to road accidents (Autor: 2020). This text shows the risk assessment of one of the three sites that were used as an object of study and that the Secretariat of Public Safety (SSP) of Mexico City characterized as conflictive due to the high rate of accidents.

Urban mobility is one of the major concerns for the quality of life of the urban population. Few studies focused on evaluating the current conditions of accessibility and safety in transport in Brazilian municipalities. This study carried out a diagnosis of the current situation of Brazilian municipalities regarding meeting the goal proposed by the Sustainable Development Goal (SDG) 11.2, which deals with the accessibility of transport systems in a sustainable, safe way. Data from questionnaires from official and public domain sources and a sample of 64 municipalities. The method included qualitative analyses, descriptive statistics and multivariate analysis techniques. Of the total municipalities studied, 45.3% are in the Southeast region, 20.3% in the Northeast region, 18.7% in the South region, 9% in the Midwest region, and 6.2% in the North region. It was identified six sets of information for the questionnaires, referring to Legislation, Accessibility, Participatory Policy, Infrastructure, Bus fare, and Vehicles. The study highlights the need for improvement of existing surveys for assessing SDG targets and actions with the municipalities to improve reported information. Urban observatories need to be developed for data dissemination and information sharing.

Territorial vulnerability of cyclist people in VW FINSA región, Puebla – Tlaxcala Metropolitan Area

2025-07-10T18:28:49+00:00

Core – periphery theory explains inequality relations in different territorial scales. This research adresses the use of bicycle as a response to colloquial expression “cyclist people”, which marginalizes this mean of transport within the context of automotive industry in the Puebla – Tlaxcala Metropolitan Area (PTMA). The aim was to quantify bicycle use in urban locations around the VW industrial core, in PTMA, and illustrate its vulnerability. A 5.5 km radius around the industrial core was defined and 30 traffic intersections were appraised to register the amount of cyclists. Findings show that bicycle use in suburban locations is up to 11 times higher than in those near the industrial core. Marginalization of bicycle use in Volkswagen FINSA region is related to industrial and urban conditions of territory and locally exemplifies global dichotomy between core and periphery.

Analysis of Bike Racks in Urban Parks of Porto Alegre/Brazil: Where Do People Lock Their Bicycles?

2025-07-10T18:28:50+00:00

The bicycle has been rapidly gaining popularity in large cities as an alternative mode of transportation, intertwining with other issues such as cycling infrastructure and urban parks. These elements offer numerous benefits, including improved health, urban mobility, social interaction, safety, environmental awareness, and tourism. Unfortunately, they are often treated separately in urban planning. Therefore, the objective of this study is to analyze data from different sources related to cycling infrastructure and two urban parks in Porto Alegre, Brazil. The focus is on bike parking facilities known as "bicycle racks," which are part of the cycling network and provide cyclists with secure spaces to leave their bikes. The research was conducted quantitatively through questionnaires and on-site surveys at Farroupilha Park and Marinha do Brasil Park, utilizing various data sources obtained online. The results revealed that cyclists generally do not secure their bikes in urban parks, and it is believed that the location of the bicycle racks is responsible for this. Therefore, these locations should be reconsidered to better align with the needs of cyclists. Bicycle racks should be situated near points of interest, visible (with high foot traffic), and designed with a secure bike locking mechanism.

Dimensión socioespacial de la inmovilidad urbana: una mirada desde el teletrabajo

2025-07-10T18:28:51+00:00

The text aims to explore the socio-spatial dimension of urban immobility favorable for permanence in space and waiting in time based on a specific activity: teleworking. To achieve this, the work activities with the greatest potential for teleworking are identified and linked to the positive and favorable impacts of immobility on the development of cities, especially because trips to work are the main reason for traveling in large Mexican cities. The study universe includes the 14 millionaire metropolitan areas of Mexico. The study period is 2019-2023. The results qualify the potential for voluntary immobility, as the number of salaried workers who have the capabilities, skills and work in activities that allow teleworking. The research contributes to the advancement of urban accessibility studies, from the perspective of the relationship of limitation and unequal distribution of access to immobility through teleworking, as a positive alternative that favors achieving more sustainable and friendly cities for their inhabitants.
