Special Issue Information

Dear Colleagues,

This Special Issue of Energies, “Sustainable Public Transport,” will consist of manuscripts describing problems and challenges for modern public transport systems.

The modern approach to city planning generates new expectations for mobility. Vehicle numbers are increasing, as is the number of journeys/trips being made. This results from changes in people’s lifestyles, the habits created, and the increased convenience associated with personal transport. This development of individual transport contributes to the deterioration of road conditions (congestion), harms the environment due to air and noise pollution and energy consumption, and causes the deterioration of residents’ health (due to increased use of personal transport). Most countries aim to increase public transport usage to reduce factors such as pollution and noise. To plan a modern transport system, it is necessary to plan for passengers and design it around environment friendliness and high accessibility. Public transport must fulfill many transport requirements (directness, frequency, accessibility, reliability, low cost, speed, punctuality, regularity, accurate information, comfort, etc.) and meet passengers’ expectations. A modern bus fleet is another essential criterion/factor for increasing travel by public transport. Currently, to decarbonize public transport, there is a transition towards electric propulsion. Public transport is essential for mobility in urban areas to reduce the negative impact of individual transport.

We invite all scientists and practitioners to submit articles related to modern solutions used for the public transport system in urban areas, reducing pollution and maximizing energy efficiency. Ensuring the appropriate quality of its functioning is a big challenge facing smart cities. It requires a multicriteria approach, taking into account the principles of sustainable development. We hope that this Special Issue of Energies will be an opportunity to present the research results and exchange experiences.

Both original research and review works are welcome for submission. Research topics of interest include but are not limited to models and methods of:

public transport optimization;
public transport development;
sustainable mobility shaping and planning;
information technologies in a public transport system;
transit-oriented development strategies in urban areas;
energy networks in smart cities;
conventional, hybrid, and electric drive systems;
various communication environment and innovative new mobility service;
the sharing economy in public transport;
safety in public transport;
the implementation of the MaaS-integrating public transport systems.

A Method for the Identification of Critical Interstop Sections in Terms of Introducing Electric Buses in Public Transport

by Adrian Barchański, Renata Żochowska and Marcin Jacek Kłos

Abstract

Among the activities that cities are taking to reduce the emissions of harmful substances emitted by conventional engine-powered vehicles is replacing the fleet with electric vehicles in public transport that can operate in urban areas. Fleet conversion is a process in which one of the decisions that must be made is the choice of lines that should be served in the first place by electric buses. Due to the specificity of the battery charging process, the routes of lines serviced by electric vehicles should run through sections that are as little exposed to disruptions as possible, which can adversely affect the travel time of these sections. The main goal of the article was to develop a method that supports the search for bus lines that are characterized by the highest level of reliability and punctuality and therefore also by the stability of the travel time between stops. The proposed method makes it possible to indicate critical interstop sections that have the greatest impact on the sensitivity of the line to disturbances. It was assumed that the more critical sections of the route, the greater the risk of bus delay, which may be disadvantageous in the case of electric vehicles due to the need to reach the battery charging station in time. The method was implemented on the example of selected lines in the Upper Silesian region (Poland) for data covering four years (2016–2019). The proposed approach allowed for the development of the ranking of lines, corresponding to the order in which the conventional fleet should be changed to electric. Full article

Real-Time Charging Scheduling and Optimization of Electric Buses in a Depot

Abstract

To improve the air quality in urban areas, diesel buses are getting replaced by battery electric buses (BEBs). This conversion introduces several challenges, such as the proper control of the charging process and a reduction in the operational costs, which can be addressed by introducing smart charging concepts for BEB fleets. Therefore, this paper proposes a real-time scheduling and optimization (RTSO) algorithm for the charging of multiple BEBs in a depot. The algorithm assigns a variable charging current to the different time slots the charging process of each BEB is divided to provide an optimal charging schedule that minimizes the charging cost, while satisfying the power limitations of the distribution network and maintaining the operation schedule of the BEBs. A genetic algorithm is used to solve the formulated cost function in real time. Several charging scenarios are tested in simulation, which show that a reduction in the charging cost up to 10% can be obtained under a dynamic electricity price scheme. Furthermore, the RTSO is implemented in a high-level charging management system, a new feature required to enable smart charging in practice, to test the developed algorithm with existing charging infrastructure. The experimental validation of the RTSO algorithm has proven the proper operation of the entire system. Full article

Abstract

The paper introduces a discussion regarding the development of a public bike-sharing system, considering random factors, based on selected external environmental analysis methods. The global energy crisis is forcing scientists to continuously improve energy-efficient sustainable methods and scientific solutions. It is particularly important in transportation since transport activities and the constant increase in the number of vehicles have a large share in global energy consumption. The following study investigates the social, technological, economic, environmental, and political aspects of bike-sharing systems in cities. The research purpose of the article is to select the most important macro-environmental factors and their mutual interaction influencing the sustainable development of bike-sharing systems based on the Polish cities case study. The evaluation was carried out through expert methods with STEEP environmental analysis, evaluation of factors with the weighted score, and structural analysis method with MICMAC computer application. The classification of key factors influencing the development of a bike-sharing system has divided them into five groups. It can support public transport service providers and organizers. This can optimize the planning process with decision-making based on future environmental trends. Full article
