Abstrakt: The problem of urban logistics operations in the context of their impact on the environment has become the key challenge. Due to that, there has been a growing interest in increasing the use of alternative fuels, including electro-mobility. However, an important barrier to the utilisation of electric freight vehicles (EFVs) is their travel range and battery capacity. The paper is focused on the idea of EFV utilisation improvement by implementation of charging stations in unloading bays. First, the Authors analysed the efficiency of chosen vehicles during daily work. Next, the potential improvement of their travel range was analysed, considering the short-time charging processes carried out during delivery operations, using the charging systems provided in unloading bays. Moreover, the concept of wireless chargers utilisation was proposed as a challenge for future work. According to the analysis, utilisation of unloading bays equipped with short-time battery chargers could improve significantly the travel range of EFVs. As a result, it could improve the efficiency of electric vehicles in last mile deliveries in city areas.

Miejsce publikacji: Sustainable Cities and Society
Rok: 2021
Słowa kluczowe: sustainable development, Sustainable urban freight transport, Social impact, Human behaviour, Driver’s choice, Impact modelling
Abstrakt: The intensive growth of urban freight transport leads to an increase in the amount of transport links, which causes problems such as traffic congestion, an imbalance between the transport services demand and the actual capacity of roads, and the negative impact on the environment. This leads to advanced requirements for urban industrial infrastructures. To optimise freight flows, it becomes necessary to determine the patterns of how drivers choose their routes between the origin and destination points. Drivers participate directly in the transportation process. From the driver’s perspective, decision-making about the current route is predicated on the technological parameters of the transportation process (speed, time, etc.), the traffic load of the urban roads, and traffic safety, but also on the level of influence of urban freight flows on the environment. The environmental impact of transportation processes is directly related to the quality of life of city dwellers and increasing of the city sustainability level. This research paper aims to determine the patterns of urban freight flows generation while considering the human factor. The choice of route parameters is significantly affected by individual characteristics of the drivers, which are dependent on the properties of the central nervous system. These properties are grouped by type of temperament. Traffic parameters on different routes have various effects on drivers of dissimilar temperaments. Having estimated the influence of each parameter on the drivers, it is possible to identify preferences of choosing a driving route from among many alternatives. The results of the survey made it possible to determine the parameters of the routes chosen by the drivers moving between the points of departure and arrival of goods, considering the age and temperament of the drivers. The results of the research study described the models for changing the share of origin-destination trips of freight transport, which is performed by drivers of different temperaments along each of the possible routes. This information can be used in modelling of freight transport flows within a city. It could significantly influence the quality of life in the cities and make cities more compliant with social expectations.

Słowa kluczowe: city logistics, electromobility, urban freight transport, city sustainability, city users’s needs, transport system impact, electric freight vehicles
Abstrakt: City users gladly apply comfortable and time-saving e-commerce solutions as an alternative to traditional purchase. The present pandemic crisis made this issue even more important. It significantly increased the number of transport operations within the city area, as each order has to be delivered directly to the purchaser. Consequently, city authorities are confronted with the important challenge: how to fulfil the expectations and needs of city users in the context of transport system functioning in view of reducing the negative impacts of urban freight transport in terms of safety, air pollution or noise. This is one of the most important elements of social sustainability in cities. One of the solutions that help reduce the negative environmental impacts of urban freight transport is making use of vehicles that produce less air pollution, such as electric vans. It proved to be very effective in decreasing transportation footprint by reducing local emissions of e.g. PM or NOx. However, one of the key limitations is the potential short driving range of such vehicles, which results from the battery capacity and charging infrastructure availability. In recent years, some analyses related to that issue have been made. Nevertheless, the studies have taken into account passenger cars only. This paper presents the results of the research study aimed at verification of electric vans energy efficiency in real-life conditions, i.e. when delivering courier consignments. The electric van used for the purposes of the experiment was Nissan eNV200. This paper fulfils the important knowledge gap and could be helpful from both theoretical and practical perspectives. It should be emphasised that the experiment was carried out in real-life conditions, i.e. in the course of performing business processes in one of the worldwide known CEP companies. The research study was carried out under the EUFAL international project, funded under the Electric Mobility Europe programme. The results of the research shown high potential of electric vehicles and usefulness of electromobility in last mile deliveries. The business partner of the research is now on the stage of electric freight vehicles implementation into vehicles fleets.

Tytuł : Ecological utility of FQP projects in the stakeholders’ opinion in the light of empirical studies based on the example of the city of Szczecin
Autor/Autorzy: Kinga Kijewska, Mariusz Jedliński, Stanisław Iwan
Miejsce publikacji: Sustainable Cities and Society
Rok: 2021
Słowa kluczowe: Freight Quality Partnership, sustainable development, sustainable transport, urban freight transport, City users, Environmental awareness, Sustainable city logistics
Abstrakt: As an idea, Freight Quality Partnership (FQP) has been worked on for a few years. Though most successfully implemented in the United Kingdom, these init6iatives were also positively implemented in other countries, among others under projects such as C-LIEGE. Presently, absence of analyses related to the FQP results awareness from the different city logistics stakeholders’ perspective is observed. With almost 10 years of experience in developing the FQP in Szczecin, the Authors conclude that this issue is of critical importance for future sustainable development and improvement of such initiatives. The paper focuses on analysis of the key city logistics stakeholders’ environmental awareness in the context of projects implemented under the Freight Quality Partnership, based on the example of Szczecin (Poland). It is as the emanation of the social and economic priority – the sustainability concept. Based on the relevant literature review, the Authors made an attempt to identify the ecological utility of FQP activities. Further, the paper presents the results of a questionnaire-based research depicting levels of environmental awareness, manifested by various groups of UFT stakeholders in Szczecin. The research has been divided into two parts – the first focuses on internal FQP stakeholders (FQP members), and the second focuses on external FQP stakeholders (various city users and local authorities). The results show in what manner different stakeholders’ groups recognize and assess the FQP activities.

Słowa kluczowe: Sustainability, Sustainable development, Sustainable urban freight transport, City users, Quality of life, Social impact, Stakeholders’ engagement, Urban freight policy
Abstrakt: Sustainable growth is a solution to reduce the negative effects of transport systems functioning in cities. It deals mainly with analysing the reasons for excessive exploitation and deterioration of the environment and specifying a strategy for limiting the process in the following areas: ecological, economic, social and cultural. The most effective activities in a sustainable urban transport policy combine all the aspects while minimising the costs connected with meeting the expected goals. Stakeholders’ engagement is essential for the effectiveness of sustainable urban mobility plans. This paper proposes a tool for assessing the level of maturity of the engagement of urban freight transport stakeholders, comparing cities in Brazil, Poland and Norway. We proposed the minimum requirements of stakeholders’ engagement and levels of maturity based on the literature. A comparative analyse was performed. The results indicate that Brazilian cities represent a low level of maturity, Polish cities represent intermediary level, and Norway cities, mainly Oslo, represent the more advanced level of maturity in the stakeholder’s engagement. The results also indicated that the cities with sustainable urban mobility plans represent the highest level of maturity in the stakeholder’s engagement.

Tytuł : Six Sigma in Urban Logistics Management - a Case Study
Autor/Autorzy: Stanisław Iwan, Justyna Lemke, Kinga Kijewska, Tomasz Dudek
Miejsce publikacji: Sustainability
Rok: 2021
Słowa kluczowe: city logistic, sustainable development, urban transport, Six Sigma, Defect per Million Opportunities, business process model and notation
Abstrakt: A city as a system that constitutes one of the most important areas of human activities. The significant role to fulfill their expectations pay the goods transport and deliveries. These issues are the subject of urban logistics. In broad terms, urban logistics may be construed as a number of processes focused on freight flows, which are completed in cities, including deliveries, supply, goods transfer, services, etc. Due to the different urban logistics stakeholders’ expectations, these systems generate many challenges for managers, especially in the context of city users’ needs and their quality of life. Today, there is a lack of broadened approach and methodology to support them from the processes’ efficiency perspective. To fulfill this gap, the purpose of this paper is to apply the Six Sigma method as a support in last mile delivery management. Six Sigma method plays important role in production systems processes management. However, it could be useful in much wider perspective, including transport and logistics processes. The Authors emphasize that the Six Sigma method could be efficient approach in the last mile delivery processes’ analysis in the context of their efficiency. It helps positioning the customer satisfaction level and quantify the delivery processes defects, related to the undelivered goods. Following that it could improve significantly the last mile delivery processes efficiency. The concept is illustrated by a sample evaluation of one of the urban logistics processes: completion of deliveries. To this end, urban logistics processes were defined. In particular, the delivery completion process was mapped, and the process client was defined along with their expectations. The defects that occurred in the process were identified and analyzed. A DPMO (Defect per Million Opportunities) indicator was established for three randomly selected months. In addition, a root cause analysis of errors was performed. The sigma level for the studied process ranged from 2.61 to 2.89. The factor that had the greatest impact on the number of defects defined as failed deliveries was customer’s absence. The obtained results indicate that the delivery process should be examined in more detail.

Słowa kluczowe: city logistics, freight transport, transport process, invest project, net present value (NPV), payback period,vehicle fleet, sustainable transport
Abstrakt: Food product transportation is one of the most problematic tasks considering the specific expectations in the context of the transport conditions. It seems to be a significant challenge for the freight carriers’ decision-makers. The proper organization and management of that process is the basis for the appropriate fulfilment of the needs of customers, related, among others, to the proper quality of delivered products (such as freshness, expiration date, etc.). The additional challenge in this context is the efficient delivery at the city area, taking into account typical city transportation problems, such as congestion, narrow ways, lack of the unloading areas, etc. The role of these tasks is analyzed in this paper, on the basis of the chosen parameters and technologies of the transportation process. The purpose of this paper is to study the rational freight fleet formation in the case of changing the parameters of material flow in time. It was found that with the other unchanged parameters of material flow, the change in ambient temperature affects the technological process of transportation, the type of vehicle for its movement and the structure of the vehicle fleet. Accordingly, the types of vehicles (tent or insulated) necessary for the movement of certain material flows, which require special conditions for their transportation, have been determined, in compliance with the temperature regime and periods of their use. The organization scenarios of the transport service of the studied distribution processes were proposed, taking into consideration the change in conditions for the transportation of material flow, purchase of insulated semitrailers or their rent. The proposed versions were calculated and evaluated under the given conditions, and based on the net present value, the best of the proposed options was found: the purchase of one insulated semi-trailer while hiring the remaining insufficient insulated vehicles.

Tytuł rozdziału monografii: Pedestrian Safety in Smart Cities – The Challenges and Solutions
Autor/Autorzy: Katarzyna Sosik, Stanisław Iwan
Rok: 2020
Słowa kluczowe: Smart City, Intelligent Transport System, Safety of pedestrian
Abstrakt: The increase in the level of urbanisation is associated with the dynamics of changes taking place in the world. The literature on the subject described the contemporary structure of society as an information society or a knowledge society. Common access to information resources and participation in their acquisition affects the use of knowledge resources in industrial systems. The development of the information society determines the availability of ICT solutions. In the era of the information society, changes in expectations towards the urban transport system have become significant. The complexity of transport processes has made it necessary to use telematics systems to enable effective management. The main purpose of telematics solutions in road transport is to eliminate transport congestion. The European Union and the member states are taking action to solve transport problems. Due to the information revolution and globalisation, special attention is paid to ensuring safety for road users. Prevention of transport and industrial disasters was set as the goal of the transport system development. The effect of the aforementioned activities is interest in the Smart Cities concept. In recent years, much attention has been devoted to ensuring safety for road users, including the use of Smart City tools. In particular, innovations created for the needs of road vehicle users are noticed. Designing, producing and implementing technology supporting the safety of vulnerable road users, including pedestrians, is becoming a problem. Many European cities create original propositions of good practices in this area. The article reviews the existing solutions of Intelligent Transport Systems in the field of Smart City supporting pedestrian safety.

Abstrakt: One of the most important problems in the cities is atmospheric emission of anthropogenic origin. This problem is the key challenge mostly for city municipalities but also for business stakeholders, which are involved in freight transport at urban areas. One of the most important and efficient solutions to reduce this negative impact is implementation of electric vehicles. In recent years many activities and developments in this area have been done. This paper is focused on utilization of multi-criteria analysis for electric vehicles selection in the context of their usability for deliveries realization in cities. Moreover, it also presents general issues regarding the use of alternative fuels in motor vehicles, with emphasis on electric vehicles. It discusses the extent to which electric vehicles are used. It describes the key parameters for determining the usability of electric vehicles in urban deliveries. Based on the formulated assumptions, a multi-criteria model is proposed to enable selecting, out of the defined vehicles catalogue, solutions that are optimal in terms of potential effectiveness. The general aim of the paper is to support the logistics companies’ decision makers in the improvement of the freight vehicles fleets, taking into account the sustainable city logistics expectations.

Miejsce publikacji: Transportation Research Procedia
Rok: 2019
Słowa kluczowe: cargo distribution, urban logistics, supply chain, forwarder, transport
Abstrakt: Distribution processes are major links in logistics chains. However, there are many hindrances to those processes, and quick elimination of those difficulties is essential for the process effectiveness. In this context, invaluable help is provided by IT tools such as freight exchange platforms, integrated management systems (ERP, CRM), fleet management systems, etc., as their application makes it possible to mitigate many hindrances. Apart from that, forwarders play a significant role in efficient coordination of deliveries. These aspects become particularly important when such processes take place within urban areas. The specific nature of distribution processes implementation in cities is determined by both the complexity of transport networks and considerable interactions with other users of the road infrastructure, as well as the environmental and social aspects. This article aims to presenting the role of carriers in elimination of hindrances, in order to ensure efficient implementation of distribution processes in cities. To ensure the efficient functioning of the logistics chain it is necessary to identify any restrictions affecting the execution of transport and forwarding orders.

Tytuł monografii: Application of Telematics Solutions for Improvement the Availability of Electric Vehicles Charging Stations
Tytuł rozdziału monografii: Development of Transport by Telematics
Autor/Autorzy: Stanisław Iwan, Mariusz Nürnberg
Rok: 2019
Słowa kluczowe: Electric vehicles (EV), Telematics systems, Charging stations
Abstrakt: Electric vehicles (EV) are becoming more popular, therefore its number is increasing especially in large cities, the advantages of such vehicles are most noticeable there - lack of local emission and negligible noise. Following the popularity of EV, there is an increasingly dynamic development of charging infrastructure. The number, power and availability of the charging stations increases. The physical access to the charging station is becoming a real problem, the specificity of charging an EV means that in practice the place next to the station is a parking space and despite the markings it is occupied by other vehicles. The paper presents the concept of solving the problem of unauthorized use of charging stations by using a telematics system based on proximity detectors, whose main purpose is signaling the availability of stations and cases of unauthorized use of the charging station.

Słowa kluczowe: City logistics, Urban freight transport, Adaptability, Transferability, Implementation, Development
Abstrakt: Urban freight transport is a part of a complex system comprising a considerable number of various participants, numerous limitations, fragmentation of goods flows, which decreases the transport effectiveness, pivotal connections in supply chains, and also the risk of conflicts between expectations of particular stakeholders. The problems require that a well-thought approach to implementation decision making should be applied. A prerequisite for a correctly implemented process of urban freight transport optimisation and rationalisation is an ex ante, in-depth analysis of the current situation and condition of a given urban system, a well performed assessment of obtained results and correct identification of goals for future actions. The paper is focused on the methodological assumptions for the implementation of the city logistics measures based on the adaptability and transferability approach. The major objective is to establish the general framework for this kind of activities.

Abstrakt: Unloading bays are one of the most popular and simple to implement measures in city logistics systems. Th e main strength of this measure is that it eff ectively reduces congestion eff ect due to that loading or unloading operations are realize in special area and not infl uence directly on traffi c fl ow. However, the most important problem in utilization of unloading bays is their inappropriate use (as a normal parking space, not only for delivery vehicles during the delivering process) and the confl icts between users in the case of few deliveries at the same time and with utilization of the same unloading bay. Th e way to solve these problems is implementation of the telematics tools.

Tytuł: Application of AHP and DEMATEL Methods in Choosing and Analysing the Measures for the Distribution of Goods in Szczecin Region
Autor/Autorzy: Stanisław Iwan, Kinga Kijewska, Witold Torbacki
Miejsce publikacji: Sustainability
Rok: 2018
Słowa kluczowe: urban freight transport, city logistics, decision making process, multi-actor decision support, multi-actor decision support, Multi-Criteria Decision Analysis (MCDA), Analytic Hierarchy Process (AHP), Decision Making Trial and Evaluation Laboratory Method (DEMATEL)
Abstrakt: Urban areas are centres of business and innovation. Freight transport is indispensable for the proper functioning of any modern urban society. Urban areas cannot function without an appropriate freight transport system, due to the need to replenish stocks of food and other goods in retail shops. The complexity of the decisions concerning implementation of measures to improve the movement of goods in the city requires tools designed to support this process. In this context, a research gap and a research problem occur—how to obtain a reliable set of factors for development of sustainable urban freight transport (UFT). The purpose of this article is to introduce the possibility of applying the Analytic Hierarchy Process (AHP) as well as the Decision Making Trial and Evaluation Laboratory Method (DEMATEL) in choosing a set of measures and in analysing the field of distribution logistics, which will help to solve delivery problems and streamline cargo flow in Szczecin, in the context of sustainable development. This paper presents the findings of a survey in which experts evaluate the main coefficients for sustainable freight transport in the city area. Using both AHP and DEMATEL methods, we have concluded that: (i) all coefficients from administrative, financial, technical and promotional measures are highly interconnected; (ii) strategy of freight transport development should take into consideration how these coefficients influence each other; (iii) P2—eco-driving trainings, T4—alternative delivery systems and P1—promotional campaigns for sustainable transport are the most important criteria and should be priorities for investments; (iv) A1—implementation of loading/unloading and transit restrictions—highly influences other coefficients; (v) T2—intelligent route guidance in freight transport is greatly influenced by them.

Autor/Autorzy: Stanisław Iwan, Mariusz Nürnberg, Kinga Kijewska
Rok: 2018
Słowa kluczowe: Fleet management systems, Telematics, Urban freight transport, City logistics, Multi-criterial decision, AHP making
Abstrakt: Fleet Management Systems (FMS) allows to manage a significant amount of spatially distributed objects, providing real-time information about its status and location, as well as information about the environment in which they are located. The amount of information that contemporary FMS can provide to decision makers is enormous and allows for a significant facilitation of transport optimization processes. This means that these systems can be an important support also for the implementation of tasks related to the operation of urban freight transport. The main problem, however, is the selection of the right tool among the many available on the market. The paper uses elements of the analytical hierarchy process (AHP) to evaluate selected Fleet Management Systems from the perspective of the end-user’s needs, with particular emphasis on increasing the time and economic efficiency of the management process.

Tytuł rozdziału monografii: Assumptions of Social Cost–Benefit Analysis for Implementing Urban Freight Transport Measures
Autor/Autorzy: Stanisław Iwan, Izabela Kotowska, Kinga Kijewska, Mariusz Jedliński
Rok: 2018
Słowa kluczowe: Social cost‐benefit analysis, urban freight transport, sustainable transport, city logistics
Abstrakt: Social cost‐benefit analysis (SCBA) aims to assess whether the planned solution will bring greater social benefits than the expenditure incurred. This chapter focuses on the assumptions of SCBA for implementing urban freight transport projects. Social benefits resulting from the introduction of individual solutions / best practice in city logistics are due to the reduction of external costs. Therefore, measurable social benefits are the difference in external costs generated before and after the introduction of the solution. External costs generated by urban freight transport are mostly environmental costs covering the cost of climate change, air pollution and noise and congestion costs associated with the increase in travel time and transport accidents. Determination of external costs requires a very detailed identification of the number of vehicles entering the area by type, capacity and Euro norm.

Słowa kluczowe: Urban freight transport, Environmentally friendly transport, Unloading bays, Bicycle freight, Cellular automata, Pollution models
Abstrakt: Urban freight transport contributes to a number of environmental problems, such as poor air quality, noise and greenhouse gas emissions. Analysing the impact of UFT measures is particularly important, since improving the situation for freight deliveries more often than not will be at the expense of the citizens. Unloading bays are one of the most popular and simple solutions to implement to support the development of a sustainable urban freight transport system. This measure is aimed at reducing the congestion in busy city streets, which is often caused by delivery vehicles parking directly on traffic lanes to perform their (un)loading operations. The analysis, presented in this paper, is aimed at emphasising the advantages of unloading bays for the public, and thus enhancing the arguments in favour of popularisation of unloading bays. We simulate the traffic in areas of Szczecin and Oslo, and compare the situation without unloading bays to the situation with unloading bays. This is used to predict the benefits of unloading bays in terms of traffic flow and emissions. The basis of the analysis is utilization of a scenario-based approach and cellular automata simulation.

Rok: 2017
Słowa kluczowe: City logistics, Transport pollution, Transport environmental impact, Data collection Methodology, Urban freight transport
Abstrakt: The dynamic development of transport in recent years constitutes an important factor in the economic development of the world, but it is also a source of problems, which can be observed especially in urban areas. A growing number of city users results in increased demand for freight distribution, the large part of which is generated by industrial, retail and service entities. The distribution function initiated by these entities causes an increase in the logistics flows within a limited area. The main problem arising in the process of analysing the functioning of transport and distribution of goods in cities is lack of data regarding classification of vehicles, their routes, demand for transport, etc. The objective of the paper is to present the methodology and results of research done in Szczecin (Poland). It fills the information gap in the functioning of UFT in the analysed area.

Abstrakt: Atmospheric emissions of anthropogenic origin are one of the most important problems in cities. A particularly discrete ecological footprint in urban environment is made by urban freight transport. This problem has become the key challenge for all stakeholder groups involved in freight transport in urban areas. Over the recent years, there has been a growing interest in using alternative fuel vehicles in urban logistics, including those equipped with electric drive systems. This paper presents a multi-criteria analysis (MCA) of selected electric vehicles (EVs) in the context of their application for the purposes of deliveries in cities. In methodological terms, we present a unique MCA-based approach for evaluation of Electric Freight Vehicles (EFVs). A successful attempt is made to build a multistep MCA procedure based on two carefully selected MCDA methods (PROMETHEE II and fuzzy TOPSIS) to handle both certain and uncertain data sets in a single decision process. In practical terms, we uccessfully demonstrate the usefulness of the proposed approach by creating a set of decision maker’s preference models (based on certain and uncertain data) of carefully selected EFVs and provide sensitivity and robustness analyses of the obtained solutions.

Słowa kluczowe: computer simulation, traffic optimization, transport management, traffic analysis, symulacja komputerowa, optymalizacja ruchu, zarządzanie transportem, analiza ruchu
Abstrakt: The dynamics of development of transport systems in cities makes it harder to control the proper traffic management. It happens that decisions on the reorganization of the traffic and utilization of automated control are made on the basis of insufficient principles. Due to that, the costs of the technical implementations are spent without a simultaneous traffic improvement. For this reason, it is necessary to use tools allowing an efficient analysis of the current and future situation of the road. Utilization of a computer simulation seems to be most effective. The paper is focused on an example of computer simulation analyses of the two integrated cross roads in Szczecin. Based on the simulation model, the assessments of the planned implementation solutions were realized. It includes the analysis of the appropriateness of traffic lights utilization for the analyzed road sections.

Słowa kluczowe: logistyka miejska, miejski transport towarowy, rozwój zrównoważony, transport zrównoważony, napędy alternatywne, pojazdy elektryczne, elektryczne pojazdy dostawcze
Abstrakt: Cele rozwoju zrównoważonego sprawiają, że coraz większego znaczenia nabiera poszukiwanie rozwiązań pozwalających na ograniczanie negatywnego wpływu systemów transportowych na środowisko. Jednym z kluczowych wyzwań jest wdrażanie koncepcji zrównoważonego transportu w miastach. Biorąc natomiast pod uwagę złożoność procesów dystrybucyjnych i ich znaczenie dla współczesnych struktur miejskich, szczególna rolę odgrywa tutaj logistyka miejska, którą należy postrzegać przede wszystkim przez pryzmat realizacji dostaw. Od kilkunastu lat w obszarze miejskiego transportu dostawczego można zaobserwować intensyfikację działań zmierzających do redukcji jego negatywnego oddziaływania na środowisko. Wśród nich istotna rolę odgrywa wdrażanie rozwiązań opartych na alternatywnych systemach napędowych. Obecnie w Unii Europejskiej skupiono uwagę na możliwościach jakie dają w tym zakresie napędy elektryczne. W artykule zaprezentowane ogólne zagadnienia dotyczące stosowania napędów elektrycznych w pojazdach samochodowych, ze szczególnym uwypukleniem pojazdów mogących znaleźć zastosowanie w logistyce miejskiej . Dokonano przeglądu obecnego stanu wiedzy a także analizy wybranych modeli pojazdów. Uwypuklono także szanse oraz ograniczenia w zakresie zastosowania elektrycznych pojazdów dostawczych w systemach logistyki miejskiej.
