After great efforts towards the development of the electric vehicle (EV) industry and the use of its products in public transportation networks, more electric buses operate in China than in any other country in the world. As more investors will enter the industry, the effect of new participants on the development of the EV industry becomes an important issue. Based on the analysis of several key stakeholders (central and local governments, electric bus producers, users/bus companies, and providers of charging infrastructure in public transportation, this paper constructs a dynamic game-theory model to determine the main participants and their strategic space payoff functions, and ultimately estimates a Nash equilibrium. The dynamic game-model analysis clearly shows that the government’s decision to provide subsidies or not is currently affecting the entire industry and is an important prerequisite for a dynamic game. The user decides the pace of the development of this industry and the user’s management efficiency is a key factor affecting users’ needs. In addition, the availability of EVs and charging station facilities are equally important to the development of the industry. Full article

As a new type of green bus, the pure electric bus has obvious advantages in energy consumption and emission reduction compared with the traditional fuel bus. However, the pure electric bus has a mileage range constraint and the amount of charging infrastructure cannot meet the demand, which makes the scheduling of the electric bus driving plans more complicated. Meanwhile, many routes are operated with mixing pure electric buses and traditional fuel buses. As mentioned above, we focus on the operating organization problem with the multi-type bus (pure electric buses and traditional fuel buses), aiming to provide guidance for future application of electric buses. We take minimizing the energy consumption of vehicles, the waiting and traveling time of passengers as the objectives, while considering the constraints of vehicle full load limitation, minimal departure interval, mileage range and charging time window. The energy consumption based multi-type bus operating organization model was formulated, along with the heuristic algorithm to solve it. Then, a case study in Beijing was performed. The results showed that, the optimal mixing ratio of electric bus and fuel bus vary according to the variation of passenger flow. In general, each fuel bus could be replaced by two pure electric buses. Moreover, in the transition process of energy structure in public transport, the vehicle scale keeps increasing. The parking yard capacity and the amount of charging facilities are supposed to be further expanded. Full article

An increasing number of cities are transitioning from fossil fuel-powered buses for public transport to battery electric buses, but there is still much confusion about the economic evaluation of the electrification of buses, especially in terms of the carbon asset value for carbon emissions reduction in this transition. Taking Beijing as the example, this paper studies the economic value of the transition of public buses from fossil fuel-powered buses to battery electric buses from the perspective of carbon asset theory, and mainly focuses the analysis on direct carbon emissions. First, the theory and methodology of carbon asset evaluation are introduced for the transition from fossil fuel-powered buses to battery electric buses. Second, the internal determinants of the carbon assets for the transition from fossil fuel-powered buses to battery electric buses are studied. Third, the distinct impacts of the determinants of the carbon assets of the transition from fossil fuel-powered buses to battery electric buses are analysed. The results indicate that (1) the transition from fossil fuel-powered buses to battery electric buses has a carbon asset value; (2) the carbon asset value of the transition from fossil fuel-powered buses to battery electric buses is determined by the distance-specific CO₂ emissions of fossil fuel-powered buses, the carbon price and the annual driving distances of the buses as well as the discounted rate of the carbon assets for buses and the termination time of the fossil fuel-powered or battery electric buses; and (3) the carbon assets contribute to the economic value of the transition from fossil fuel-powered buses to battery electric buses. This paper provides academic support for the economic evaluation of the transition from fossil fuel-powered buses to battery electric buses in a low-carbon society. Full article
