“…The nearly 300 existing trolleybus systems worldwide are a relatively small number [27]. Scientific research concerns particular policies in the field of urban electric transport development, including trolleybuses [10,15,[28][29][30][31], comparative studies of the development of various means of public transport, including trolleybuses [21,[32][33][34] and the impact of means of transport on the environment, in particular, greenhouse gas emissions, CO 2 and other harmful substances [28,[35][36][37][38][39]. Few studies concern technical issues, including trolleybus drives [40][41][42], power supply infrastructure and catenary [43], vehicle development [19,20,44,45] and technical facilities [46].…”

The current developments in onboard power source technology, in particular, traction batteries, open up new potential in trolleybus transport and also make it possible to introduce electric buses. Thus far, trolleybus transport has required the presence of overhead lines (OHL). Introducing trolleybuses with onboard batteries makes it possible to grow the zero-emissions transport network in places with limited power supply capabilities and low population density, or in places where building OHL would not be possible. This improves the efficiency of trolleybus transport and makes environmentally friendly public transport more accessible to the local citizens. Despite their obvious advantages, traction batteries can also be problematic, as the drivers may overuse them (e.g., in the event of pantograph failure), and the public transport authorities and transport companies may plan connections in an ineffective way without preparing the necessary infrastructure (the absence of slipways or automatic connection capabilities), which in turn leads to inefficient use of the OHL. The article outlines the operation of the trolleybus transport network in Gdynia. The use of traction batteries in regular connections is analysed, and the potential for electrification of the bus line, some sections of which follow the traction infrastructure, is examined.

“…Keeping in mind these reciprocal interactions between mobility and urban space, it is worth exploring in what respect sustainable transport modes, and particularly public transport systems, affect the urban environment and the quality of the urban space, given its recognized significant capacity for 'placemaking' [4,5,29]. Essentially, sustainable transport modes are those alternatives to private vehicles in urban mobility such as walking, cycling, personal light electric vehicles and public transportation -especially electric powered -under global and continuous upgrade and development [9,11,30,31]. The increasing participation of theses modes in the urban mobility will help to promote high-quality accessibility and contribute to the high-quality environment of cities [9].…”

The urban environment and the quality of the urban spaces are greatly affected by different forms of mobility, from the extremely impactful mass use of private vehicles to the 'soft' pedestrian walkways and cycle paths, and also through the several modes of public transport. In this paper we first explore the different urban impacts of these forms of mobility and the interaction between the urban system and the transportation system, and we then analyse the relationship of factors promoting urban quality in accordance with literature on urban design. Next, an analysis of the street's cross section is made, as the quality of this space is inextricably linked to its grade of sustainable mobility. The results of this study are contrasted with the experience within Granada's metropolitan area, which has a high level of private vehicular use, for example its heavy congestion coupled with severe environmental pollution. A new light rail system (LrT) has been developed, with major urban renewal along its track. The LrT has the particularity of having varied cross sections, whereby the improvement in quality of urban space along them can be evaluated. The high-quality urban spaces are those with virtually no vehicular access whatsoever, providing a completely pedestrianized area, such as in the traditional urban road crossing axes in the outlying districts, which are now almost completely free from vehicles and are more greatly accessible to people. As a result of current social distancing required by the cOVID-19 pandemic, urban space, which can be configured in a very adaptable way, is changing in many cities including Granada, giving more space in their streets to sustainable mobility modes and, therefore, indirectly increasing their quality and longevity. The changes carried out in Granada reveal a requirement for the promotion of improvement in urban spaces and sustainable mobility on a metropolitan scale, since the LrT is not enough if it is not accompanied by other urban development and mobility integrated measures.

“…With reference to exhaust gases emitted by urban transportation, this encompasses a wide range of effects on human health [10][11][12]. Literature suggests that urban traffic is responsible for 40% of CO2 emissions and 70% of the emission of other pollutants arising from transport [13].…”

This article utilized a multicriterial quantitative and qualitative analysis of the influence of eco-friendly methods in reducing emissions over the life cycle of automotive products. The new proposed multicriterial method is applicable where preferential criteria are independent of each other, and where uncertainty has not been incorporated into a formal model. The linear model showed how the values of several criteria related to the options could be combined into an overall value. The main objective of this research was to apply a multicriterial methodology to improve the accuracy of existing approaches in identifying the influence of eco-friendly methods to reduce emissions over the product life cycle, and to assist decision makers in the manufacturing process. The research questions were as follows: Which one of two automotive products ("Bus" or "Truck") has the best environmental performance (EPP)? Which one of two automotive products ("Bus" or "Truck") has the best overall environmental performance (EPAPL)? This research provided a detailed comparative analysis of a "Crosstown bus" and a "Tractor truck", both made at the Industrial Park Romania Brasov, Romania, using a multicriterial analysis. This article provided an answer to the first research question, whilst only presenting the results for the second question. The results of the proposed multicriterial method applications provide a decision support base for environmental managerial decisions in the field of automotive production processes.
