A completive survey study on the feasibility and adaptation of EVs in Beijing, China

The private motor vehicles are significantly important means of transportation in modern lifestyle, however, these also contribute to a large proportion of the total air pollution and primary energy consumption. In order to develop green transportation system, it becomes imperative to use integrated technologies to achieve reduced emissions and utilize renewable energy. Electric vehicles (EVs) have been considered as one of these technologies to transform the traditional vehicle mix. However, the uptake of EV has been debated on factors like cost, performance (autonomous mileage), charging point infrastructure construction, energy saving, policy and end users’ adaptation. Present study investigates the technology feasibility (which usually refer to EVs’ cost, EV charging, supplier’s customer services quality, EV travel performance) and users’ adaptation of EV in Beijing, which is a key driver for the EV uptake into the Beijing transportation system. The relevant data have been collected and analyzed in the form of questionnaire survey around all of these factors. While considering the user perception and satisfaction, safety of charging and energy bills have also been investigated. According to the data analysis, it has been found the policy of ‘No traffic restrictions for EVs’ (the traffic restrictions means for certain date, from Monday to Friday the motor vehicles with the last register number of 1 and 6, 2 and 7, 3 and 8, 4 and 9, 5 and 0, are restricted to travel, respectively), the availability of the charging infrastructure and technical support are the most significant factors affecting the users’ opinions on using EVs.

Green air transport system: An overview of issues, strategies and challenges

Globally, the environmental sustainability of air transport is receiving greater concern nowadays owing to its critical impact on climate change. This paper provides an overview of the environmental (green) issues in relation to aviation activities, focusing on aircraft emission and noise. The influential factors of the respective green issue (including aircraft characteristics and operations) as well as the relevant mitigation strategies, ranges from the technological innovation, operational strategy, fleet planning to the policies, rules and regulations are discussed accordingly. Besides, mathematical modeling, statistical analysis and survey which emerge to be the main methodologies adopted to alleviate the green issues are also discussed in detailed. Concisely, the literatures reveal that there is no single strategy or approach that can be implemented to ease the green issue. Thus, integrated effort and commitment from the relevant parties are required to yield a greener system. By identifying the literature gaps and also the potential rooms for improvement under uncertainty, it is anticipated that this paper could provide some useful insights to the relevant parties in charting the effective strategies to attain a green air transport system.

Assessing carbon reduction effects toward the mode shift of green transportation system

SummaryPlans are underway to introduce green transportation systems at Taiwan's famous scenic spot, Sun Moon Lake, to reduce carbon emissions. Carbon reduction effects after changing the current lake tour modes are assessed using a nested logit model with a stated preference survey, which investigated tourists' choice preferences. The empirical results reveal that the modes of electric bus, electric vehicle sharing, and bike are clustered in the same competitive group. Travel cost, in‐vehicle travel time, and out‐vehicle travel time are found to be statistically significant with the expected negative effects. In particular, the attribute of carbon reduction is only significant for green tourists, who are willing to pay US$ 3.5/kg of carbon saved. The result indicates that more efficient carbon reduction is possible by restricting the usage of gasoline vehicles rather than improving the service levels of low‐carbon modes. Notably, the effect of parking charges on emission reduction is equal to the amount of carbon dioxide absorbed by 4511 trees per day. Copyright © 2016 John Wiley & Sons, Ltd.

Changing Transportation System in University Campus by Cycling and its Impact on Socio-Cultural Characteristics

In Malaysia, universities’ public transportation is less than ideal. This discourages its vast public acceptance and use, particularly in the favor of using private vehicles. That in turn shows its adverse effects, such as traffic jams, environmental pollution, etc. Universities are respected institutions, and pace-setters, in the position to alter and improve the "intellectual culture" in any society. A college campus is open to the public, and its scrutiny. The way public transportation is managed in the campus, could serve as a model for the whole community in large. If we establish an efficient streamlined public transportation system on campus, well received by the faculty, student body and personnel, it would not be long before it is noted by the whole community. A college campus in a sense is public, and belongs to all. Moreover, University Putra Malaysia (UPM) is a leading institution among the other Malaysian universities, notable for its sustainable physical layout. From the research, interview and discuss had been done regarding the effectiveness of power position and municipal authorities. It includes the input from a questionnaire filled by 100 students of UPM University, regarding improvement of public transportation and green transportation systems. This research also addresses a variety of transportation systems -especially cycling- and their conduciveness to social interaction on campus. In this study, we will have the provisions to incorporate our suggested solutions to campus transportation system, into the overall layout of campus planners and university organizers. Ideas and recommendations for solutions would be considered at the end of the study. The ideas and improvements should be well publicized, to promote the public awareness, and its acceptance. In time, it would be engrained as a cultural improvement. Without acceptance, any change would be of little use. Key words: Socio-culture characteristics, in campus transportation, social interactions.

Comparative Analysis of Activities for More Environmental Friendly Urban Freight Transport Systems in Norway and Poland

Negative effects of urban distribution of goods in terms of energy consumption and air pollution are caused mainly by a low level of cooperation between partners in the supply chain, and also the low effectiveness of transport systems. The issues of urban freight transport functioning and effects on the city environment have recently been more and more often taken into account. Many projects on a local, regional, national as well as cross-boundary scale have emerged, with a direct focus on limiting the negative impacts of urban freight deliveries on the environment. In this paper the authors introduce a study performed for Polish and Norwegian cities focused on initiatives concentrated on activities aimed at limiting the negative impacts of freight transport on urban environment. A comparative analysis of the Polish and Norwegian projects was made, taking into account both quantitative and qualitative aspects. This was the first part of the GRASS (GReen And Sustainable freight transport Systems in cities) research project, which is being undertaken by the Maritime University of Szczecin and the Institute of Transport Economics from Oslo through the Polish-Norwegian Research Programme.

Transit Traffic Analysis Zone Delineating Method Based on Thiessen Polygon

A green transportation system composed of transit, busses and bicycles could be a significant in alleviating traffic congestion. However, the inaccuracy of current transit ridership forecasting methods is imposing a negative impact on the development of urban transit systems. Traffic Analysis Zone (TAZ) delineating is a fundamental and essential step in ridership forecasting, existing delineating method in four-step models have some problems in reflecting the travel characteristics of urban transit. This paper aims to come up with a Transit Traffic Analysis Zone delineation method as supplement of traditional TAZs in transit service analysis. The deficiencies of current TAZ delineating methods were analyzed, and the requirements of Transit Traffic Analysis Zone (TTAZ) were summarized. Considering these requirements, Thiessen Polygon was introduced into TTAZ delineating. In order to validate its feasibility, Beijing was then taken as an example to delineate TTAZs, followed by a spatial analysis of office buildings within a TTAZ and transit station departure passengers. Analysis result shows that the TTAZs based on Thiessen polygon could reflect the transit travel characteristic and is of in-depth research value.

ITS for Sustainable Mobility: A Survey on Applications and Impact Assessment Tools

Road transportation is one of the main sources of greenhouse gas emissions, which lead to global warming and climate change. Promoting the decarbonization of this sector through more efficient and greener mobility is a challenging task that can be achieved by intelligent transportation systems (ITS) enabled by vehicular communications. In this paper, we briefly present how mobility players and enablers (driver, vehicle, and road network) influence energy consumption and pollutant emissions. Furthermore, this survey paper details how different ITS, ranging from eco-routing to intelligent intersection management, can lead to sustainable mobility by promoting a more efficient vehicle usage and enhanced efficiency on road network utilization. Results shown that ITS has the potential to considerably reduce fuel consumption and pollutant emissions, namely, by smoothing the traffic flow, reducing the number of start–stops, and reducing the total travel distance. In addition, we present and analyze two main methods for evaluating green transportation systems: 1) field operational tests; and 2) simulation-based evaluations. We give special emphasis to simulation-based assessment of Green ITS measures by detailing the necessary models and their interactions. Finally, we propose a number of recommendations and future research directions in the area of Green ITS.

Sensitivity Analysis of Characteristic Parameters of Railway Electric Traction System

The modal analysis, which decouples the contact wire and rail track conductors, is used to develop an integrated model of single rail track and contact wire. The characteristic impedance and propagation constant matrices of integrated model have been computed. The authors have studied effects of various parameters of interest on characteristic impedance and propagation constant using sensitivity analysis. The sensitivity functions of series impedance and shunt admittance related to contact wire and catenary have been developed and validated in this paper. Index Terms—railway traction lines, characteristic parameters, sensitivity analysis, parameter sensitivity  I. INTRODUCTION Railway electric traction system is a fast and green transportation system with enhanced load carrying capacity. The analysis and design of power and signaling system of railway electric traction system needs mathematical model of the system. The authors in this paper have used the multi-conductor transmission line theory to develop the mathematical model of the electric traction system and to compute the characteristic impedance and propagation constant of this system. This approach can then be extended to find the voltage and current distribution of the system. The characteristic impedance and propagation constant are the functions of line parameters i.e. self and mutual impedances and admittances of contact wire and rail track. The numerical values of these parameters are not accurately known under practical conditions as they are dependent on varying/uncertain parameters like permeability, supply frequency and shape of the conductor. In order to study the effect of these uncertain parameters on the characteristic parameters of the railway electric traction system, the authors have carried out the sensitivity analysis of characteristic impedance and propagation constant with respect to the above mentioned parameters of interest for the first time in the literature. In a rail track ferromagnetic material, both saturation and hysteresis are

Green Transport System: A Technology Demonstration of Adaptive Road Lighting with Giant Magnetoresistive Sensor Network for Energy Efficiency and Reducing Light Pollution

To enhance energy efficiency and reduce light pollution of overnight road lighting in suburban traffic, we propose a novel green transport system based on giant magnetoresistive (GMR) sensors. The basic principle is to detect the perturbation to the earth magnetic field by a ferrous vehicle with GMR sensors. This system can switch on the road lighting to full illumination gradually before the motor vehicle arrives and dim it out after the vehicle leaves without the driver noticing. Based on a sparse suburban road in the countryside of Hong Kong, a demonstration model was constructed to illustrate its feasibility. GMR sensors and the associated electrical energy control components including signal processors, relays, and dimmers were integrated into a complete system. The experimental result indicates that the sensing principle is feasible and the whole system can function together coherently to achieve over 90% energy saving. Such system can be scaled up to be implemented in real road conditions.
