Electric vehicles are the transportation machines which uses electric energy as power source for movement. The objective of this technical journal is to propose an idea to solve the electric automobile problems which are causing the backlog for sales and demand of electric automobiles in the Indian market. This is a technical journal consisting of a case study of electric vehicle problems in India, applications and advantages of electric vehicles, simple analysis of problems one by one based on common thinking abilities, disadvantages in electric vehicles, discussion of preferable solutions for the electric vehicle problems and its disadvantages, field survey, listing the situation in order systematically, different types of batteries that can be used, motors that can be preferred for electric automobiles, preferred solution discussion including result discussion with an example of electric automobile and finally conclusions. We have discussed on batteries and motors that are suitable for electric vehicles. We have tried to solve the problems of electric vehicles after listing the problems that can be faced in electric vehicles one by one. The main concept of this paper is having the battery exchange stations to exchange the charge dried batteries to fully charged batteries. In battery exchange stations, a customer using electric vehicles should pay some amount and can exchange his used batteries to fully charged batteries. We have discussed the way of working of battery exchange stations. Hydrogen fuel cell concepts are also detailed in this paper.

The increasing interest in sustainable modes of transport such as public transport has triggered the need for evaluation of accessibility to and from the transit service. Accessibility to the transit service determines the service attractiveness and hence better accessibility increases the demand. Although accessibility has been the focus of research in the past few decades, it still remains a concept that has been poorly defined and hence finding a theoretically good and operationally sound measure of accessibility is a challenging task. The objective of this paper is to develop a composite public transport accessibility index using Geographic Information System (GIS) as a case study of an Indian city, Trivandrum. This concept is a spatio-temporal GIS-based public transport accessibility model which includes travel modes of walking and bus transit, travel impedance and service coverage of the transit network. The methodology used in the study is based on the factor that the index should measure the accessibility which comes from proximity to bus stops and land use destinations and the proportion of the population served.

AbstractDiesel fuel combustion results in exhaust containing air pollutants and greenhouse gas emissions. Many railway vehicles use diesel fuel as their energy source. Exhaust emissions, as well as concerns about economical, alternative power supply, have driven efforts to move to hydrogen motive power. Hydrogen fuel cell technology applied to railways offers the opportunity to eliminate harmful exhaust emissions and the potential for a low- or zero-emission energy supply chain. Currently, only multiple-unit trains with hydrail technology operate commercially. Development of an Integrated Hybrid Train Simulator for intercity railway is presented. The proposed tool incorporates the effect of powertrain components during the wheel-to-tank process. Compared to its predecessors, the proposed reconfigurable tool provides high fidelity with medium requirements and minimum computation time. Single train simulation and the federal government’s Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET®) model are used in combination to evaluate the feasibility of various train and powertrain configurations. The Piedmont intercity service operating in North Carolina is used as a case study. The study includes six train configurations and powertrain options as well as nine hydrogen supply options in addition to the diesel supply. The results show that a hydrail option is not only feasible, but a low- or zero-carbon hydrogen supply chain could be possible.
