“…A reduction of 9.2% in the total system costs was the result of this study compared to Kunith et al's outcome [56]. Olmos et al [69] investigated the problem of locating opportunity charging infrastructure for hybrid and fully electric buses to find the best locations for such facilities. The two other objective functions in their paper were the power rates of opportunity charging infrastructures and the sizes of energy storage systems.…”

Transit agencies are increasingly embracing electric buses (EB) as an energy-efficient and emission-free alternative to the conventional bus fleets. They are rapidly replacing conventional buses with electric ones. As a result, emerging challenges of electrifying public transportation bus networks in cities should be addressed. Introducing electric buses to the bus transit system would affect the public transit operation planning steps. The steps are network design, timetabling, bus scheduling, and crew scheduling. Regarding the functional and operational differences between conventional buses and electric buses, such stages should be changed and optimized to enhance the level of service for the users while reducing operating costs for service providers. Many mathematical optimization models have been developed for conventional buses. However, such models would not fit the electric buses due to EBs’ limited traveling range and long charging time. Therefore, new mathematical models should be developed to consider the unique features of electric buses. We present a comprehensive literature review to critically review and classify the work done on these topics. This paper compares the studies that have been done in this field and highlight the missing links and gaps in the considered papers, and the potential future studies that could be done. The considered papers cover the integration of timetabling and vehicle scheduling, recharging scheduling planning, and fast charging infrastructure location planning and its impacts on the grid. The main goal of this research is to highlight the research gaps and potential directions for future studies in this domain to encourage more realistic and applicable models and solution approaches for fully electric bus transit systems.

Problem. City electric buses are increasingly being utilized for passenger transportation in developed countries worldwide. Currently, there are various types of city electric buses being manufactured and operated, differing in their autonomous electric energy sources and charging systems. These include the ONC type with overnight charging of traction batteries and the OS type with ultra-fast charging of traction batteries or supercapacitors during stops. However, these electric buses also vary in their body length, ranging from 5.85 to 15.0 meters for individual models. Although large-class city electric buses with a body length of approximately 12.0 meters are commonly used, concerns have been raised regarding their operational effectiveness. Goal: This study aims to evaluate the feasibility of designing and implementing small-scale production of competitive middle-class city electric buses with a body length of 8.0-10.0 meters at Ukrainian enterprises, and to assess their suitability for operation on city routes. Methodology: The feasibility evaluation of middle-class city electric buses is based on an analysis of the technical parameters of promising ONC-type middle-class city electric buses. The study includes the development of conceptual sketch projects based on a proposed layout scheme utilizing a 4x2.1 wheel formula. Operational parameters of these sketch projects are compared with electric bus analogues of similar and other standard sizes. Results: Three versions of conceptual sketch projects for promising urban electric buses of the ONC type, with body lengths of 8.0 meters, 9.0 meters, and 10.0 meters, have been developed. An analysis of their structural and operational parameters has been conducted, providing a relative assessment of the feasibility of their creation and utilization for passenger transportation on urban routes within domestic cities. Originality: The projects for promising middle-class urban electric buses are developed based on an original layout scheme, incorporating an asymmetrical arrangement of independent suspensions for the left and right wheels of the steering bridge, as well as the placement of two double passenger doors in the middle section of the bus bodies within the wheelbases. A method for determining the primary structural parameters of city electric buses of varying lengths during the development of conceptual proposals is proposed. Practical Value: The study presents a rational basis for creating and establishing the production of medium-class city electric buses of the ONC type, highlighting their operational and economic advantages compared to modern models, particularly large-class city electric buses produced by domestic companies. The study also provides recommendations for selecting optimal standard sizes of middle-class city electric buses for integration into urban passenger transportation systems in Ukraine's current stage of economic development
