“…AVs are generally equipped with an electric battery, which also increases the acquisition cost of the vehicle. However, as in the case of AVs, operating costs may be reduced compared to conventional vehicles due to lower maintenance and energy costs required for electric powertrain [25][26][27][28][29][30]. It is also expected that battery prices go down with time and hence electric vehicles become cost effective compared to conventional vehicles in the long term [31,32].…”

There is rapidly growing interest in autonomous electric vehicles due to their potential in improving safety, accessibility, and environmental outcomes. However, their market penetration rate is dependent on costs. Use of autonomous electric vehicles for shared-use mobility may improve their cost competitiveness. So far, most of the research has focused on the cost impact of autonomy on taxis and ridesourcing services. Singapore is planning for island-wide deployment of autonomous vehicles for both scheduled and on-demand services as part of their transit system in the year 2030. TUMCREATE developed an autonomous electric vehicle concept, a microtransit vehicle with 30-passenger capacity, which can complement the existing bus transit system. This study aims to determine the cost of autonomous electric microtransit vehicles and compare them to those of buses. A total cost of ownership (TCO) approach was used to compare the lifecycle costs. It was shown that although the acquisition costs of autonomous electric vehicles are higher than those of their conventional counterparts, they can reduce the TCO per passenger-km up to 75% and 60% compared to their conventional counterparts and buses, respectively.

“…Ayyildiz et al [22] compared fuel consumption and carbon emissions in terms of driving styles before and after eco-driving training. Tong et al [23] estimated the life-cycle ownership costs for buses and infrastructure as well as the environmental externalities of greenhouse gases and air pollutants emitted during the life cycle of buses powered by alternative fuels. These studies have shown that environmental effects are significant and should not be ignored when considering transport effects.…”

Public transport plays an important role in the environment. This study established a Spatial Computable General Equilibrium (SCGE) model to examine the economic and environmental effects of public transport subsidy policies. The model includes firms, consumers, and traffic modules in one framework. Statistical data from Beijing were used in calibration to obtain benchmark equilibrium. Based on the equilibrium, simulations compared citywide social welfare, jobs-housing spatial population distribution, and environmental outputs under four subsidy policies: fare subsidy, cash grants, road expansion, and public transport speedup. Based on the results regarding the effects of public transport policies, conclusions can be drawn about which policies will have greater overall social influence and should therefore be used.

“…Climate change and public health are two global issues that arise from the use of fossil fuels in transports and need to be addressed urgently [1]- [3]. Public transport is generally regarded as a sustainable mode of transportation, as emissions per passenger are lower than those of automobiles, although, conventional diesel buses contribute to air and noise pollution, especially in high density areas [4]- [6].…”

“…Public transport is generally regarded as a sustainable mode of transportation, as emissions per passenger are lower than those of automobiles, although, conventional diesel buses contribute to air and noise pollution, especially in high density areas [4]- [6]. However, promising alternatives to the conventional fossil-fueled engines are making their way into buses used in public transportation -the most promising of which are the battery-electric and the hydrogen fuel-cells powered engines, more energy-efficient and far less pollutant than the conventional diesel engines [2], [3], [7]. Buses using either of these two fuel technologies will be referred hereafter to zero emission buses (ZEBs), as neither type generates any pollutant emission.…”

“…The transition to their large scale use in public transportation is still in the early stages due mainly to limited driving range and acquisition costs. These vehicles are more expensive to procure than conventional buses: an electric bus will cost in the range of €350,000-500,000, whereas a diesel bus will cost €200,000-250,000 -cost remains a major adoption barrier [3], [9], [10]. Additionally, either electric or hydrogen recharging stations need to be installed, and these drive up the cost of ZEB operations as they are more expensive than conventional diesel stations [8].…”

Transports are among the major sources of atmospheric pollution, causing climate change and public health damage. Public transportation is a well-known, recognized solution to greatly decrease transport emissions, especially when making use of zero emissions buses in the fleet, such as buses driven by batteries or by hydrogen. However, cost imposes a large barrier on zero emissions buses. The transition to the use of such buses is expensive, and it must be driven by several stakeholders, thus motivating service providers to make efforts towards zero emissions buses implementation strategies. In this study, citizens from a Russian district capital city were questioned on their potential role as contributors to the zero emissions buses transition, by studying their willingness and attitudes to pay a premium for the bus fares, in order to supplement the public transport agencies revenues. It was found that environmental concern and air pollution concern can be critical factors driving consumers into paying premium, but not noise pollution. Based on this study, there are several recommendations proposed for practitioners, as well as several future research avenues. In this article we seek to investigate how the consumers' attitudes and concerns over the environment and city pollution could influence their willingness to play a role as supporters of the introduction of zero emissions buses in the public transportation fleet, since understanding the consumer attitudes is essential to perform and run an efficient public system.
