Moving a wheelchair is a task which requires both the physical and mental engagement of either an assistant pushing it, or the rider controlling it. Pushing it can be physically demanding and limits the number of wheelchairs that can be moved, to one. Our research introduces a technology that may enable a wheelchair to independently follow the rider or assistant. This will allow the rider to disengage from the task of moving the wheelchair, and allow for more riders to be assisted by an assistant at one time. We have developed a Socially Interactive, Gesture-Aware, Human-Following, Transport system (SIGHT) in order to provide more freedom of action to assistants who are providing the same level of service to riders with less effort. Indeed, SIGHT allows for a human to interact with the wheelchair on a more social level. By using gestures, such as waving, the assistant and wheelchair can communicate.

Integral Element

Vulnerability in the Railway system is, studied not only from the perspective of network topology characteristic but also as the problem of the level of service relative to structure, nature damage and traffic attribute. Also, emphasis is put on the function of the system rather than the physical network itself, although some of non-serviceability in the railway network is indeed caused by physical failures. The Vulnerability of railway network is thus a decisive factor not only in terms of connectivity, and serviceability, but also in terms of the transport system performance under dynamic process-traffic which should be acknowledged as an integral element within vulnerability assessment. The paper aims at investigating the most typical factors that affect the vulnerability. The vulnerability analysis must consider each factor separately, and, at the same time, as a whole. A method to measure the vulnerability is proposed. Furthermore, this assessment method is used to analyze the Chinese Railway Network (CRN).

Analysis Process

This paper presents the research and analysis process showing that transport system customers have a specific perception of service quality, as an indicator of transport system. Determining satisfactory level of service quality implies knowledge of travel demand and travel behaviour. There are a lot of elements that define the transport system quality. The goal of this paper is to identify the public transport system’s service quality elements that should be primarily acted on, in order to increase the level of service quality from transport system users’ (public transport users’ and non-users’) point of view, with minimal investment. The paper describes a specifically defined research methodology for determining service quality elements that should be primarily acted on, from the transport system users’ point of view. Methodology involves the use of Importance Performance Analysis (IPA) which is upgraded with the state preferences analysis. Presented methodology, which is used to determine user perception of service quality, can be considered to be universal. This methodology can be applied in other cities, with additional research that must precede its use. The methodology was tested on transport system users in Belgrade.

Public transportation is one of the sustainable form of transportation which provides mobility options for the people. The public transport services are very basic need of people’s lives, especially in developing world. It is the basic means for mobility of a large percent of people and hence it is the driving force of economic and social life. Quality of service, characterized by the Level-of-Service (LoS) is one of the major factors determining the demand for public transport. This study tries to determine the city-wide Level-of-Service provided by the public transport system using the service level benchmarks as a case study of Trivandrum city. The indicators for determining the Level-of-Service used in the study are presence of organized public transport system, availability or extend of public transport supply, service coverage, average waiting time, level of comfort in public transport and the fleet availability. This approach can be used to determine the LoS at the city-level and thus provides a measure for identifying the public transport quality of an urban area.

This article deals with the issue of a partial problem in the sustainability and availability of public transport using the example of a specific transit node. In every public transport network, it is the transit nodes that can be a threat to the entire transport system in case of a bad design. The article presents a microsimulation traffic model of a transit node, which was created in the PTV VISSIM/VISWALK program. This model was tested by various traffic loads (i.e., normal loads, loads taking into account the extension of the tram network and loads at extraordinary sports or cultural events). As part of the evaluation of the monitored node, the movement of passengers on pedestrian areas, escalators and staircases was analysed. The obtained results demonstrate the importance of monitoring, for example, the Level of Service, average travel times and pedestrian speeds and other parameters, to ensure the functionality of this construction. The use of traffic models can be crucial, as they can be an invaluable aid and a suitable tool in finding the optimal transport solution that respects the requirements for sustainable and accessible public transport.

Active Transport System

The plasma membranes of most animal cells contain transport proteins which function to provide passageways for the transported species across essentially impermeable lipid bilayers. The channel is a passive transport system which allows the movement of ions and low molecular weight molecules along their concentration gradients. The pump is an active transport system and can translocate cations against their natural concentration gradients. The actions and interplay of these two kinds of transport proteins control crucial cell functions such as active transport, excitability and cell communication. In this paper, we will describe and compare several features of the molecular organization of pumps and channels. As an example of an active transport system, we will discuss the structure of the sodium and potassium ion-activated triphosphatase [(Na+ +K+)-ATPase] and as an example of a passive transport system, the communicating channel of gap junctions and lens junctions.
