“…In order to better ensure that the GNG emissions estimates use in the [23] study was within range, the study used the data of five (5) other independent studies as a comparison mechanism. When a data range was provided in a particular comparison study, a low and high value was used, corresponding to a worst and best case scenario, respectively.…”

Traditionally, the process used by public transportation entities to determine the acquisition strategy for new vehicle asset is based upon a broad range of criteria. Vehicle cost has been cited as one of the more critical factors which decision makers consider. It is currently a common practice to consider other factors (life-cycle cost, fuel efficiency, vehicle reliability, environmental effects, etc.) that contribute to a more comprehensive approach. This study investigates the next generation of advancements in decision making tools in the area of the application of methods to quantify and manage uncertainty. In particular, the uncertainty comes from the public policy arena where future policy and regulations are not always based upon logical and predictable processes. The fleet decision making process in most governmental agencies is a very complex and interdependent activity. There are always competing forces and agendas within the view of the decision maker. Rarely is the decision maker a single person although, within the transit environment, there is often one person charged with the responsibility of fleet management. The focus of this research examines the decision making of the general transit agency community via the development of an expert systems prototype tool. A computer-based prototype system is developed which provide an expert knowledge-based recommendation, based upon variable user inputs. The results shown in this study show that a decision making tool for the management of transit system alternate fuel vehicle assets can be modeled and tested. The direct users of this research are the transit agency administrations. The results can be used by the management teams as a reliable input to inform their urban transit buses expansion decision making process. Keywords

“…Most of the recent researches address the comparison of diesel, hybrid diesel-electric, compressed natural gas, hydrogen fuel-cell and battery electric buses [4][5][6][7]. Only very few studies are dedicated to the evaluation of different battery electric bus technologies [8] such as opportunity and overnight charging.…”

Public transport authorities particularly in conurbations and mega-cities undertake growing endeavours to improve their CO 2 footprint and become less dependent on fossil fuels. Electric buses are an obvious alternative to conventional diesel vehicles. However, public transport authorities face several different options of electric bus technologies and different system solutions to implement electric buses. These options have specific assets and drawbacks concerning technology, capital and operational cost. Despite the importance of this issue only very limited research has been published on that matter so far.This study presents a technology assessment of battery-electric public bus systems based on technical and economical key performance indicators. The methodology is applied to an electric bus project for the city of Berlin. To facilitate the selection of a suitable technology a step-wise approach is applied. Firstly, an energetic simulation model has been set up to forecast the needed energy for daily service based on bus operating profiles in Berlin. Secondly, a pre-selection of potential electric bus solutions is made by qualitative evaluation of different systems using defined technical and economic indicators. Thirdly, a detailed comparison is made between the remaining technological alternatives taking monetary-based aspects into account. The economic analysis is conducted by means of a total cost of ownership (TCO) approach.In conclusion the examination reveals that under Berlin conditions inductive opportunity charging technology fulfills the comprehensive system's requirements and shows relatively low TCO values.

The transition toward sustainable urban transportation has gained importance in recent decades. However, urban transportation has not been addressed for all dimensions of sustainability. This study presents a life cycle sustainability assessment of a light rail transit system in Kayseri, Turkey, by integrating environmental, economic, and social aspects. The sustainability performance of the light rail transit system is evaluated using a cradle‐to‐grave approach to assess three aspects of sustainability. For the environmental evaluation, a life cycle assessment was applied using SimaPro 8.4.1 PhD version based on ISO 14040 and 14044. The method, which includes nine environmental impact categories, was employed to assess the environmental performance of the light rail transit system with a functional unit of 1 passenger‐km. For the economic assessment, life cycle costing was utilized with the functional unit of USD for 1 passenger‐km. A social life cycle assessment was applied to assess the social performance of the light rail transit system based on guidelines published by the United Nations Environment Programme in collaboration with the Society of Environmental Toxicology and Chemistry. For the determination of social impacts, 11 subcategories and 18 social indicators were selected. The results showed that the global warming potential and abiotic depletion potential of the light rail system per passenger‐km were 2.4E − 02 kg CO2 eq. and 2.7E − 01 MJ, respectively, with a service life of 50 years. The total life cycle cost of the light rail system was calculated as 0.046 USD for 1 passenger‐km. The results also revealed that the main contributor to the total life cycle cost was energy cost, with 92% (2.88E + 08 USD) of the total cost. In the social performance evaluation, it is found that the industry performs well for society, the local community, and workers but has a weaker social performance for the consumer due to a weak feedback mechanism.
