Projekt: PNRR iNEST - Vernetztes Nord-Ost-Innovations-Ökosystem

Urban mobility management faces growing challenges that require the analysis and optimization of sustainable solutions. Digital twins (DTs) have emerged as innovative tools for this assessment, but their implementation requires standardized procedures and languages; Methods: As part of a broader methodology for continuous DT validation, this study focuses on the conceptual validation phase, presenting a conceptualization approach through formalization using Specification and Description Language (SDL), agnostic to simulation tools. The conceptual validation was achieved through stakeholder engagement in the Bolzano context, producing 41 SDL diagrams that define both elements common to different urban realities and specific local data collection procedures; Results: The feasibility of implementing this stakeholder-validated conceptualization was demonstrated using Simulation of Urban MObility (SUMO) for traffic simulation and optimization criteria calculation, and its framework SUMO Activity GenerAtion (SAGA) for generating an Activity-Based Modeling (ABM) mobility demand that can be improved through real sensor data; Conclusions: The SDL approach, through its graphical representation (SDL/GR), enables conceptual validation by enhancing stakeholder communication while defining a framework that, while adapting to the monitoring specificities of different urban realities, maintains a common and rigorous structure, independent of the chosen implementation tools and programming languages.

As electric vehicle adoption grows, understanding the impact of electric vehicle charging on electricity grids becomes increasingly important. Accurate grid impact modelling requires high-quality charging infrastructure data. This study examined the electric vehicle recharging infrastructure and usage patterns in a region of the Italian Alps over a three-year period from 2021 to 2023. The primary objectives were to analyze the growth and distribution of electric vehicle charging stations, assess energy consumption, and evaluate charging behaviours across various recharging points. The research involved collecting empirical data from 411,800 recharging sessions and simulated data using the emobpy tool to model energy consumption and charging behavior. Key findings reveal a substantial increase in the number of recharging points, from 673 in 2021 to 970 in 2023, with the total energy delivered increasing from 938 MWh in 2021 to 4133 MWh in 2023. The data showed distinct temporal trends: AC points were primarily used during the day, while DC points saw higher usage during morning and late afternoon peaks, aligning with travelling times. The study’s validation of simulation results against empirical data emphasized the importance of high-quality input for accurate grid impact assessments. These findings suggest the necessity for strategic placement of recharging infrastructure and provide practical insights for policymakers, urban planners, and utility companies to support sustainable electric vehicle integration.

The environmental impact in terms of CO2 of a large-scale train infrastructure considering the electrification of heavy-duty road transport

Vaccaro R, Maino F, Zubaryeva A, Sparber W

Projekt: PNRR iNEST - Vernetztes Nord-Ost-Innovations-Ökosystem

The present study analyses the CO₂ emission balance of a large-scale rail tunnel. The CO₂ emissions during the construction phase are compared to possible savings during the operational phase, which can be achieved by shifting freight transport from road to rail. The Brenner Base Tunnel is used as case study. Electric vehicles are expected to replace gradually diesel trucks in the near future, affecting road transport. The electricity landscape is also changing strongly in Europe with greater energy production from renewable sources. The research aim is to consider the impact on the CO₂ emission balance of the electrification of road transport and the changing electricity mix. The results show that in a fully electrified road transport and decarbonised electricity system scenario, there is no direct CO₂ emission advantage of rail over road transport, still rail transport at the Brenner pass leads to a relevant energy efficiency advantage.

Projekt: EU Zero Emission LIFE IP - Null-Emissions-Dienstleistungen für eine dekarbonisierte Alpenwirtschaft

The transportation sector plays an important role in the current effort towards the control of global warming. Against this backdrop, electrification is currently attracting attention as the life cycle environmental performance of different powertrain technologies is critically assessed. In this study, a life cycle analysis of the public transportation buses was performed. The scope of the analysis is to compare the energy and global warming performances of the different powertrain technologies in the city fleet: diesel, full electric and hydrogen buses. Real world monitored data were used in the analysis for the energy consumptions of the buses and to produce hydrogen in Bolzano. Compared to the traditional diesel buses, the electric vehicles showed a 43% reduction of the non-renewable primary energy demand and a 33% of the global warming potential even in the worst consequential scenario considered. The switch to hydrogen buses leads to very different environmental figures: from very positive if it contributes to a further penetration of renewable electricity, to hardly any difference if hydrogen from steam-methane reforming is used, to clearly negative ones (approximately doubling the impacts) if a predominantly fossil electricity mix is used in the electrolysis.

Projekt: EU Zero Emission LIFE IP - Null-Emissions-Dienstleistungen für eine dekarbonisierte Alpenwirtschaft

Public bus decarbonization is increasingly important to address the global issue of climate change. There are several challenges associated with large-scale introduction of zero-emission technologies in public fleets. This is especially the case in an extra-urban context, of mountain regions with challenging weather conditions. In this work the analysis of the state-of-the-art ZEBs, local bus lines, and timetables was performed to understand the best fit of technology—battery electric buses (BEBs) or fuel cell electric buses (FCEBs)—for each line in such a region. Further, a simulation tool was developed to calculate the compatibility of zero-emission technologies with the current needs of the public transportation considering distance, altitude difference, and climate conditions. The results show that a complete switch of the fleet is possible with a slight increase in the number of buses and that there is no clear difference in the distance covered in mountainous areas by BEBs versus FCEBs, but that both technologies can cover similar distances. The tool developed is not limited to bus fleets but can be applied to all kinds of fleets that cover clearly defined daily routes.

Projekt: EU Zero Emission LIFE IP - Null-Emissions-Dienstleistungen für eine dekarbonisierte Alpenwirtschaft

Electrification of the transportation sector is one of the main drivers in the decarbonization of energy and mobility systems and it is a way to ensure security of energy supply. Public bus fleets can assist in achieving fast reduction of CO₂ emissions. This article provides an analysis of a unique real-world dataset to support decision-makers in the decarbonization of public fleets and interlink it with the social acceptance of drivers. Data was collected from 21 fuel cell and electric buses. The tank-to-wheel efficiency results of fuel cell electric buses (FCEB) are much lower than that of battery electric buses (BEB), and there is a higher variation in consumption for BEBs compared to FCEBs. Both technologies permit a strong reduction in CO₂ emissions, compared to conventional buses. There is a high level of acceptance of drivers which are likely to support the transition towards zero-emission buses introduced by the management.

Projekt: EU ITA-CH MOBSTER - Auf dem Weg zur Elektromobilität für einen nachhaltigen Tourismus

The transition to sustainable waterways transport is imperative in the face of environmental and climate challenges. Local lakes, often overlooked, play a significant role in regional transportation networks and ecosystems. This study focuses on Orta lake, Italy, and aims to facilitate its transition to sustainable inland waterways transport by substituting its diesel-based fleet with electric vessels. Firstly, a comprehensive market analysis was conducted to understand the available electric vessel models and their technical characteristics. This included parameters such as capacity, range, and charging time. Based on the market analysis, an optimization model was developed to determine the minimum number of electric vessels required to completely replace the existing diesel-based fleet. This model considers various constraints and objectives, such as meeting transport demand, minimizing the number of vessels, and reducing environmental impact. The developed model was then applied to the case study of Orta lake using the collected market data. The results indicate an optimal fleet configuration and provide insights into the feasibility and implications of the transition. This study contributes to the growing body of knowledge on sustainable inland waterways transport and offers a methodology that can be replicated and adapted for other local lakes or maritime settings.

Projekt: EU ITA-CH MOBSTER - Auf dem Weg zur Elektromobilität für einen nachhaltigen Tourismus

The European Union has seen a strong growth of electric passenger vehicles over the last decade. The steady increase in the number of electric vehicles requires a thorough examination of the current infrastructure and their future development, which are critical to the continuous market growth of this technology. The underdeveloped charging infrastructure is identified as one of the main barriers, next to the purchase price of electric vehicles. Thus, the infrastructure (supply side) and the vehicles (demand side) must coevolve and consider not only the quantitative balance between EVs and charging stations but the interlinkages with social, technical, and economic criteria for the overall system development. In this context, the methods presented in this paper address regional specificities when developing an integrated network of charging infrastructure for private and public passengers transport in an alpine region. The results of the application of the methodology to a mountainous area present the potential for replicability and highlight the importance of considering regional characteristics and of stakeholder involvement.

Projekt: EU ITA-CH MOBSTER - Auf dem Weg zur Elektromobilität für einen nachhaltigen Tourismus

Electric vehicles (EVs) are low-carbon innovations that decrease emissions in transportation. Understanding what drives individual propensity to choose EVs supports policymakers in shaping effective low-carbon mobility policies. Within the MOBSTER Interreg project, data were collected using a survey administered to residents in three Alpine cross-border regions—Canton Ticino (Switzerland), South Tyrol (Italy), and Verbano-Cusio-Ossola (Italy)—and were analyzed with a logistic regression. This study reports on the relevant drivers of EV uptake, showing (i) that some sociodemographic attributes positively impact the propensity to choose an EV (e.g., young age and teenage children), (ii) that the presence and visibility of charging infrastructures are important, and (iii) that the role of tourism is not a driver of EV uptake. This study confirms that policies should consider sociodemographics, social practices, and physical infrastructures as playing roles in EV uptake. Future research should address the issue of access to low-carbon innovations for all.

Towards the definition of a sustainable business model for last mile logistics: case study of city of Trento

Mortara M, Ponte D, Zubaryeva A

Alyona Zubaryeva

This work outlines the methodology used to analyse the economic, social, environmental and technical sustainability of an urban distribution centre (UDC) to manage last mile deliveries directed towards the historic centre of a city by using only electric vehicles. Achieving this goal requires a design of novel business model, based on evidence found in cases of real applications. Final aim of research is part of need to determine tools that can be replicated to measure and compare impacts of initiatives undertaken in different contexts. An attempt was made to offer a solution to this hurdle by creating a model capable of enclosing main aspects of interest for service, while at same time standardizing results for each case studied

Can we hope for a collective shift in electric vehicle adoption? Testing salience and norm-based interventions in South Tyrol, Italy

Della Valle N, Zubaryeva A

Alyona Zubaryeva

Electric-drive vehicles (EVs) are a promising technology for containing environmental problems of the transport sector. However, to be effective on the environment, these need to be purchased by consumers in large quantities. Not only material barriers, but also cognitive biases prevent their diffusion. Particularly, EVs fail to capture a significant passenger car market share, even in regions that can overcome most material barriers. We report the findings from an online survey experiment administered to respondents of a region identified as a potential EV lead market, but which still fails to reach a significant EV market share. We test the effect of two behaviorally informed strategies on EV preferences: a norm-based and a salience intervention. To better identify treatment effect, we control for pro-environment self-identity, heterogeneity in key economic preferences, and size. Results show that making future cost savings salient significantly increases the likelihood of choosing EVs. However, the effect is limited to individuals displaying preferences for big vehicles and for valuing future benefits, and high values in the pro-environment self-identity measure. In addition, results show that EV choices are unaffected by the descriptive norm embedded in the norm-based intervention.

Optimal allocation of electric vehicle charging infrastructure in cities and regions: the new technical research report of the Joint Research Centre of the European Commission, the European Commission’s in-house science service

A geospatial analysis of electric-vehicle charging infrastructure allocation within a city and a region, based on open source GIS tools, is described. A methodology was developed to provide optimal locations of electric vehicle infrastructure (charging stations) within a spatially extended region. Two different cases were identified: placement in a city network (urban road network) and in a regional or national network (rural roads and highways). For a city and a regional network, the methodology identifies high-potential areas for the installation of charging station. In contrast, for a highway network the methodology provides explicitly the suggested locations: the charging stations should preferably be placed in already built areas, gas stations or rest areas, to minimize additional investment costs. A pilot study was made for the city of Bolzano/Bozen (city road network) and the province of Alto Adige/Südtirol (rural and highway network). The municipality and the province gave positive feedback on the suggested locations.
