Special Issue Information

Dear Colleagues,

This Special Issue is devoted entirely to the sphere of transport. It aims to present the latest achievements—scientific research, developed technologies, and organizational and legal solutions—relating to the design, modeling, and analysis of "electrified" and sustainable transport systems. The first area of scientific interest concerns the electrification of transport systems. It should be noted that this area is very important for the implementation of the European Union's policy in the field of decarbonization and energy security. Moreover, this area is in line with the current trends in the development of electromobility in individual countries. Accordingly, this Special Issue is dedicated to considering the topics of design, modeling, and analysis relating to vehicles, infrastructure, IT tools, telematics, and logistics. The second area of scientific interest concerns sustainable transport systems. This is another extremely important area from the point of view of the European Union's transport policy. We should strive to ensure that the conducted research, developed technologies, and prepared organizational and legal solutions take into account the principle of sustainable transport development. Therefore, we should design, model, and analyze: meeting the needs of people in the field of transport safely, with the least negative impact on the health of people and ecosystems and without discrimination to people with special needs;affordable transport that runs smoothly and efficiently, offers the choice of means of transport, and supports the economy and sustainable regional development;transport that reduces the emission of harmful compounds and waste, uses renewable resources (including renewable energy sources) and non-renewable resources, and minimizes land consumption and noise generation. Accordingly, this Special Issue is also dedicated to considering the topics of design, modeling, and analysis related to sustainable transport systems.

The widespread electrification of public transportation is increasing and is a powerful way to reduce greenhouse gas (GHG) emissions. Using real-world driving data is crucial for vehicle design and efficient fleet operation. Although electric powertrains are significantly superior to conventional combustion engines in many aspects, such as efficiency, dynamics, noise or pollution and maintenance, there are several factors that still hinder the widespread penetration of e-mobility. One of the most critical points is the high costs—especially of battery electric buses (BEB) due to expensive energy storage systems. Uncertainty about energy demand in the target scenario leads to conservative design, inefficient operation and high costs. This paper is based on a real case study in the city of Seville and presents a methodology to support the transformation of public transportation systems. We investigate large real-world fleet measurement data and introduce and analyze a second-stage feature space to finally predict the vehicles’ energy demand using statistical algorithms. Achieving a prediction accuracy of more than 85%, this simple approach is a proper tool for manufacturers and fleet operators to provide tailored mobility solutions and thus affordable and sustainable public transportation.

The potential of e-bus transportation to improve air quality and reduce noise pollution in cities is significant. In order to improve efficiency and extend the useful life of these vehicles, there is a growing need to investigate improvements for the thermal management system of electric city buses. In electric vehicles, there are several systems whose thermal behaviors need to be regulated, such as batteries, electric machines, power electronics, air conditioning, and cabin. In this study, a 0D/1D model of an electric city bus is developed that integrates all sub-models of the powertrain, auxiliaries, and thermal management system. This model is used to evaluate different configurations and thermal management strategies of the electric urban bus by simulating public transport driving cycles in Valencia, Spain, under winter conditions. First, the original thermal–hydraulic circuit of the bus was modified, resulting in an improvement in the battery energy consumption with savings of 11.4% taking advantage of the heat produced in the electric motors to heat the battery. Then, the original PTC heating system of the bus was compared with a proposed heat pump system in terms of battery power consumption. The heat pump system achieved an energy savings of 3.9% compared to the PTC heating system. Full article

The energy consumption estimation of a locomotive for a particular route is important for the selection of a locomotive technology, the improvement of the energy management system, the evaluation of the locomotive’s potential energy generation, among others. The methodologies reported in the literature usually assume that the information of the railway track is available; however, in some cases, the track information is incomplete, not available, or the route is still in a planning stage. Therefore, this paper proposes a methodology to estimate the energy consumption and the potential energy generation of a locomotive when the railway track information is not available or incomplete. The methodology begins by extracting the main technical information of the locomotive to be analyzed. Then, the route is traced on Google Earth with steps of 100 m and the obtained information is processed to generate the longitude, latitude, elevation, and distance of the points along the route. From such information, it is possible to generate the slope and curvature profiles, while the speed profile can be obtained from the track operator or the regulations of a specific country. With that information, it is possible to estimate the equivalent power of the locomotive at each point of the route to finally calculate the consumed energy. The proposed methodology is validated with two case studies. The first one compares the results with a methodology available in the literature for the same route and locomotive, while the second case shows the applicability of the proposed methodology for a route without information.
