This research aims to cluster prospective passenger high speed rail service corridor Jakarta-Bandung to compensate the rapid development Bandung City as one of the favorite tourist destinations for domestic and international visitors. The data analysis Method is using non-hierarchical cluster and sampling technique by random sampling with 280 respondents. The results show that there are three clusters of prospective passenger for high speed rail service with different characteristics. The first clusters are those who depend heavily on their private vehicles, the second cluster which is the largest cluster has logical ridership characteristics and the last cluster is a group that has a high level of concern for the environment.

The rapid development of high-speed rail (HSR) and station areas has shortened the spatial and temporal distances among cities, improved the accessibility of cities, and affected the spatial agglomeration and diffusion of populations and of social and economic activities. This has led to spatial reconfiguration of production factors within cities, which has the potential to drive the reconstruction of urban spatial structures. Based on POI and land-use data, this paper defines the spatial scope of the HSR station area and explores the characteristics and influencing factors of its spatial structure from the perspective of industry. The study area i is set at 2000 m. Since the opening of the HSR, the industrial distribution has exhibited a significant circular, multi-core, and axial belt spatial structure. The spatial structure of each sub-industry is different. On the whole, internal and external transport and agglomeration economies have significant impacts on the industrial spatial distribution, and land rent has gradually decreased in importance with the development of HSR station areas. The intensity of the effects of different factors varies among different industries. The mechanisms by which the spatial structure of the station area is formed are discussed and include location accessibility, micro-market factors, node station attributes, the availability of a sufficient amount of undeveloped land, the characteristics and needs of HSR passengers, and policies and systems.

With the rapid development of high-speed railways, any objects intruding railway clearance will do great threat to railway operations. Accurate and effective intrusion detection is very important. An original Single Shot multibox Detector (SSD) can be used to detect intruding objects except small ones. In this paper, high-level features are deconvolved to low-level and fused with original low-level features to enhance their semantic information. By this way, the mean average precision (mAP) of the improved SSD algorithm is increased. In order to decrease the parameters of the improved SSD network, the L1 norm of convolution kernel is used to prune the network. Under this criterion, both the model size and calculation load are greatly reduced within the permitted precision loss. Experiments show that the mAP of our method on PASCAL VOC public dataset and our railway datasets have increased by 2.52% and 4.74% respectively, when compared to the original SSD. With our method, the elapsed time of each frame is only 31 ms on GeForce GTX1060.

High-speed rail provides a safe, efficient, and economic transportation system for regions with high population density such as eastern China. To accommodate the rapid development of high-speed rails in China, the bridges with standard spans have been identified as the main infrastructure type. This article provides a state-of-the-art review on the design and construction of the standard simply-supported beam (simple beam) bridges for high-speed rails in China. The structural components discussed include the main girder, deck, and substructure. The live load models, deformation limiting values, and construction methods for the bridges are also discussed. Additionally, the experimental tests were conducted to verify the static and dynamic performances of the structure. The main objective of this paper is to provide the latest design and construction experience of Chinese standard simple beam bridges in high-speed rail and show how a quick and quality engineering has been achieved by utilizing these standardized bridges.

The article is devoted to the experience of the implementation of high-speed railways in foreign countries and the possibility of its use in Russia. Particular attention is paid to the issues of financial and economic justification of such projects, using the criteria of commercial and budgetary efficiency. Particular attention is paid to China in the article, since this country today has the greatest experience in the implementation of projects in the field of high-speed rail communication. The emergence of high-speed rail in China not only became a technological breakthrough, but also played an important role in stimulating the country’s economy and enhancing domestic demand. At the moment, 57% of all high-speed railways in the world are in China alone. The experience of the United States is also of scientific interest, in particular, in the consideration and evaluation of high-speed rail projects. Despite the high level of economic development in the United States, high-speed rail transport is practically undeveloped, which is largely due to historical reasons. Cheap oil, along with improvements to cars and airplanes, and government subsidies for highway and airport construction, have made these vehicles more accessible to most of the population and highlighted them. Despite these circumstances, the authorities of many states are interested in the implementation of high-speed rail projects. At the same time, the question of the possibility and expediency of switching passenger flows from existing modes of transport remains relevant in the United States. In the final part of the article, using the example of specific projects, the prospects for the development of high-speed railway communication in Russia are assessed and proposals for the development of the transport complex as a whole are given.
