The studies on the video recognition algorithms based on deep learning neural network and lidar for orbit area recognition, pedestrian vehicle recognition, and small foreign object recognition are analyzed, and the necessity of the fusion of video recognition and lidar data and the related key technical points are discussed. Through the tests on domestic metro and tram lines, the feasibility of the scheme is verified, and the technical parameters are optimized, which can effectively reduce the probability of accidents caused by foreign object intrusion.</p> Jiang Yaodong Copyright (c) 2020 Jiang Yaodong https://creativecommons.org/licenses/by/4.0 https://eaapublishing.org/journals/index.php/nm/article/view/73 Wed, 02 Dec 2020 00:00:00 +0800 Overview of the Intelligent Operation and Maintenance System for Shanghai Rail transit Rolling Stock https://eaapublishing.org/journals/index.php/nm/article/view/74 <p>The traditional rolling stock maintenance model based on planned repairs and fault repairs cannot meet the needs of the rolling stock operation and maintenance for superlarge-scaled networks. There is an urgent need to establish a highly automated and information-based rolling stock intelligent operation and maintenance system based on online monitoring. This paper introduces the composition, main functions and application situations for the Shanghai rail transit intelligent rolling stock operation and maintenance system as well as suggestions for further work related thereto so as to provide references for the development of the rolling stock intelligent operation and maintenance system of the rail transit industry.</p> Tu Xiaowei, Yu Youmin, Deng Qi Copyright (c) 2020 Tu Xiaowei, Yu Youmin, Deng Qi https://creativecommons.org/licenses/by/4.0 https://eaapublishing.org/journals/index.php/nm/article/view/74 Wed, 02 Dec 2020 00:00:00 +0800 Construction of Online Monitoring System for Track Safety and its Vibration and Noise https://eaapublishing.org/journals/index.php/nm/article/view/75 <p>In accordance with the requirements of intelligent and scientific maintenance and repair for rail transit, the on-line monitoring and intelligent assessment technologies for infrastructure safety as well as vibration and noise indexes are studied. In connection with the line status of the Shanghai rail transit network, typical line sections are selected to lay out the online status monitoring equipment so as to track health and safety indexes of rails and real-time noise and vibration levels. By means of online real-time data collection and synchronous analysis technology, the Shanghai rail transit online monitoring system for track safety status and its vibration and noise takes shape, thereby achieving real-time monitoring for on-site vibration and noise as well as safety status, and providing assistant decision-making reports in connection with relevant index systems and in accordance with relevant time periods.</p> Snan Taotao, Dong Guoxian Copyright (c) 2020 Snan Taotao, Dong Guoxian https://creativecommons.org/licenses/by/4.0 https://eaapublishing.org/journals/index.php/nm/article/view/75 Wed, 02 Dec 2020 00:00:00 +0800 Verification and Optimization of Metro Fare Clearing Models Based on Travel Route Reconstruction https://eaapublishing.org/journals/index.php/nm/article/view/76 <p>How to verify and optimize metro fare clearing models efficiently and accurately is a research focus in metro operations. Metro fare clearing models are mostly based on probability distributions. In such models, the normal distribution of travel time corresponding to the section probabilities is used to calculate the route choice probabilities of passengers on a multi-route metro network. By integrating the operating mileage proportions of each metro line operator and the corresponding route choice probabilities, the fare clearing proportions are calculated for all the operators of the metro network. To verify the accuracy of the fare clearing proportions, we propose a travel route reconstruction approach based on cell phone data acquisition technique. With wireless access point (AP) sensors installed at transfer stations, the unique medium access control (MAC) address of the smart phone with Wi-Fi function turned on is recorded and transmitted to a data analysis platform. After matching the MAC address information with time and location, the travel route of the smart phone user is reconstructed. Then, the parameters in the fare clearing model are verified and optimized according to the travel route choice probabilities. The proposed methodology is applied in Hangzhou metro network for experiment, and the metro fare clearing model is verified and modified by reconstructing the actual travel routs of the local passengers.</p> Pu Yichao Copyright (c) 2020 Pu Yichao https://creativecommons.org/licenses/by/4.0 https://eaapublishing.org/journals/index.php/nm/article/view/76 Wed, 02 Dec 2020 00:00:00 +0800 A Location-Based Device Tree System for Rail Transit https://eaapublishing.org/journals/index.php/nm/article/view/77 <p>As the Vehicle Branch of Shanghai Metro Maintenance Guarantee Co., Ltd. is making continued progress in refined management, it requires increasing fine data granularity, together with increasing needs for data analysis. Therefore, the existing serial-number-based device trees can no longer meet continuous increasing management requirements, which necessitates a new device tree system. This paper has proposed a new device tree system for rail transit. Based on the physical locations of rail transit devices, the system proposed can associate the location information with property information, equipment serial number, and fault trees. Hence a subway vehicle and fault management system based on device trees was established. Based on the actual situation and management requirements of the Vehicle Branch, this paper has developed a location-based device tree management system and coding scheme, and introduced its advantages in management.</p> Li Shuyue Copyright (c) 2020 Li Shuyue https://creativecommons.org/licenses/by/4.0 https://eaapublishing.org/journals/index.php/nm/article/view/77 Wed, 02 Dec 2020 00:00:00 +0800 In search of the Interchange King in Urban Rail Lines in China https://eaapublishing.org/journals/index.php/nm/article/view/78 Rao Ya Copyright (c) 2020 Rao Ya https://creativecommons.org/licenses/by/4.0 https://eaapublishing.org/journals/index.php/nm/article/view/78 Wed, 02 Dec 2020 00:00:00 +0800 How Far Can You Travel by Metro for Five Yuan? https://eaapublishing.org/journals/index.php/nm/article/view/79 <p>With 5 Yuan, you can buy a small piece of bread or two bottles of water.
