This paper deals with the charging infrastructure for EVs in Beijing. By analyzing GPS and vehicle data from 38 real customers, a first statement could be worked out: Most customers drive, park and charge within the sixth ring road, charge at home and approach the same districts during the test duration. Additionally, different types of districts in Beijing generate various charging options. Especially...
Landsat TM images of the Pearl River Delta taken in 1988, 1998 and 2006 are used to explore the Construction land Expansion and the Influence of Site Factors. The expansion shows the characteristics of gathering on plains and along major roads and coastlines in both periods from 1988 to 1998 and from 1998 to 2006. Several site factors, including landscape types and the distance from roads, coastlines,...
The monitoring about the changes of land use and cover and NPP in mining area is one of hot spots in the field of resources and environment. Combining with ground field survey data, the remote sensing image in different periods in mining area and the geographic information technology are used to study the changes of Land Use and Cover and NPP. The results show that the degree of the change of land...
In order to make a quantitative study about accessibility of cities in China, the spatial analyst module functions of ARCGIS were mainly used to do an empirical research about it based on land traffic network structure and calculations of optimal road routes and time to cities of China, which generated accessibility diffusion graph and average accessibility graph of cities. And then, the ESDA was...
Urbanization is the both the result of the social and economic development and the essential trend of history. The time of beginning of urbanization of China is later than that of European countries, which started in late period of 19th century. Until now, the speed of urbanization is slow and the development is imbalanced in China. Nowadays, the urbanization of China is in the period of acceleration...
In the background that lots of major cities suppress the second industry and develop the third industry in China, medium-sized cities get the opportunity of development, which led to increasingly serious traffic problems. Then, setting Bus Rapid Transit in medium-sized cities is an important way to alleviate the traffic pressure. In this paper, it takes setting conditions of Bus Rapid Transit in Medium-sized...
The saturated silt ground in this area which was exerted by seismic loads was simulated numerically by using FLAC-3D. Liquefaction in surface of powder foundation occurred less likely and with the increasing depth of foundation it occurred more likely. The density of soil in upper layer increased because of the role of dynamic compaction. And as density increased, the dynamic strength of soil in this...
This paper reviews the basic method in dealing with the urban traffic of China's metropolises. It analyses of fundamental problem of urban transport development in-depth. Then we give some advantages depending on building underground road network to solve these problems in center district of plain metropolises. After analyzing, we proposed that, to achieve this goal will require study and solve urban...
In this paper, stormwater runoff from an urban traffic road and building located in Beijing, China, was characterized to measure the stormwater runoff discharge rates and pollutant concentrations. Based on monitoring, the runoff water quality on two underlying surface conditions was analyzed. The temporal dynamics of chemical oxygen demand (COD), NH3-N, NO3-N and total phosphorus (TP) were similar...
Synthetic aperture radar interferometry (InSAR) is a novel space observation technique from satellite which enjoys the merits of high spatial resolution, high precision and area matrix surveying. Especially, the Differential InSAR (DInSAR) technique has been applied to detect and monitor ground deformation. In this study the displacement on line of sight has been acquired with two-pass DInSAR processing...
Sampling method was employed to investigate the structure and ecological benefits of street trees in the area within Second Ring Road of Shenyang. The study area covers about 161 km2, and 61 main roads. Based on the field data, the i-Tree (STRATUM) model was run to analyze street trees' structure and ecological benefits. The results showed that there were 19 street tree species in the study area,...
As the main portion of urban catchment, road is also a major non-point pollution source of receiving water body. The road runoff pollution has attracted wide attention. The paper makes a study on six rainfall road runoff from 3 different types of roads, analyses the status of road runoff pollution, the surface runoff pollution load and correlation between road runoff pollutants. The result shows that...
As energy crisis poses a huge threat to human welfare, the electric vehicle is of vast potential for future development as an newly emerged traffic tool which is energy-conserving and environment-protective. However, the layout method of its charging station is far from a mature system even though the construction is being undertaken. Thus this paper presents a multi-objective planning model which...
The concept of the sustainable development is brought forward in the 1980s and has been received and paid close attention in the world. Under the new situation, highway transport is considered as an important transport, so it is worthwhile to how to play the role and provide strong guarantee for socio-economic development and achieve the own sustainable development. From the point of sustainable development,...
Optimization of international transport chain may significantly contribute a successful outcome of international trade. The performance of various transport mode influences its selection. This paper analyses and compares the transport chain between China and Austria, aiming to identify the best practices and choose the optimal transport mode. Based on analyzing secondary data, the different transport...
For a long time, the theory and practice of urban land and urban transit planning only pay attention to the demand on urban rail transit from land, but not sufficiently consider the reaction of traffic on the site. Recently, the relationship between urban land use and urban transit becomes more and more attention by the scholars. During the process of the modification of urban space layout, it is...
Evaluating the impacts of rural road investment projects is a key content in the rural roads post-evaluation. A good rural road investment project impact evaluation provides the basis for sound policy making. However, because of the lacks of impact evaluation activities and methodology, it has been difficult to know how opportunities provided by rural roads actually filter back into beneficiary outcomes...
The road tunnel which has advantages of improving the alignment criterion, educing travel distance, protecting the natural environment is increased used in China. At present, the related domestic and foreign researches are mainly based on the design scale, lining type, construction methods and difficulty, use and so on. There is little about the length definition of road tunnel based on the drivers'...
This research simulated the urban growth scenarios of a mountain city of Chongqing, China through a CA-based model of SLEUTH. The fundamental data were four Landsat TM images of 1978, 1988, 1993, and 2001 which were utilized for generating maps of land use, road networks, and urbanized area. Three alternative development scenarios, including business as usual, compact city and decentralized concentration,...
Currently in China the level of coal mine roadway roof abscission layer monitoring is low, especially in the most coal mine the transmission and observation of the underground separation data are by manual labor or by cable transmission, there is a high cost for coal mine. This paper introduces a roof abscission layer monitoring system based on ZigBee which is adapting to environment of coal mine...
