Communication based train control (CBTC) systems have been widely deployed on dedicated subway lines. However, deployment on shared rail infrastructure, where CBTC and non-CBTC trains run, leads to a mixed positioning and controlling system with different precision levels and restrictions. New performance and complexity issues are to arise. In this paper, a method for rescheduling adapted to a CBTC system running in a mixed traffic, is introduced. The proposed method is based on a model predictive control (MPC) approach. In each step, a genetic algorithm with new mutation mechanisms solves the problem to optimize the cost function. It determines the dwell times and running times of CBTC trains, taking into account the non-CBTC trains planning and fixed-block localization. In addition, reordering can be allowed by modifying the problem constraints. The work is supported by a simulation tool developed by SNCF and adapted to mixed traffic study. The approach is illustrated with a case study based on a part of an East/West line in the Paris region network, proving the ability of the method to find good feasible solutions when delays occur in traffic.","PeriodicalId":427580,"journal":{"name":"2016 IEEE International Conference on Intelligent Rail Transportation (ICIRT)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124066299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

That is the question the general public asks when railway companies say they cannot add additional services because the lines have reached maximum capacity; and it is a valid one. Mainline railways currently use a system of safe operation known as `absolute block', whereby trains are kept a safe distance apart using a principle that only one train may occupy a particular block at any one time. Traditionally, such systems are designed around the worst braking train on the route; meaning better braking trains are potentially braking earlier than necessary, hindering capacity. ETCS has the potential to improve capacity through separating trains based on their individual braking performance and the moving block capability of Level 3. However, even more capacity could be unlocked through a principle known as `closer running'. This concept is sometimes referred to as `relative block', where trains are separated according to their current relative speed, braking capability and location. This paper explores what such a system might look like, how it might work, and describes the potential benefits and safety, technical, operational and cultural challenges to making it a reality.","PeriodicalId":427580,"journal":{"name":"2016 IEEE International Conference on Intelligent Rail Transportation (ICIRT)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117207419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is, however, necessary to guarantee that the CBTC system is safe so that the safety of the whole metro system can be improved. Traditional off-line testing methods are widely used to determine whether the CBTC system complies with the desired specification, but unfortunately these testing methods are becoming insufficient due to the growing complexity and wider functional coverage requirements of the system. In particular, off-line testing methods ask for a deterministic system while the CBTC system is usually non-deterministic. To solve the problem, we propose an on-line testing method, based on a micro railway simulator and the testing tool UPPAAL-TRON, by generating and executing test cases simultaneously. Firstly, we applied the theory of Timed Automata (TA) to model a general routing procedure of the CBTC system. Secondly, the observable abstract variables in the TA-based model were mapped to the simulated variables in our micro railway simulator and the simulated variables were connected to the SUT's variables. Then, we processed the TA-based model via a black-box conformance testing tool UPPAAL-TRON to generate and execute the test case simultaneously. Finally, we analysed the testing results to determine the test coverage and to find out whether there are inconsistencies between the SUT design and its testing specification.","PeriodicalId":427580,"journal":{"name":"2016 IEEE International Conference on Intelligent Rail Transportation (ICIRT)","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114737776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LIDAR generates a point cloud by analyzing the echo of light pulses scattered from the objects surrounding the train. Since the generated point clouds are too large to be used in practical applications, they need to be converted to a simpler and more compact form, while preserving all of the important features of the environment. Moreover, LIDAR signals are often affected by various noises or interferences, which rapidly decrease the signal-to-noise ratio of the signal with increasing distance. This study proposes a multi-scale analysis (MSA) strategy for interpolation and denoising of LIDAR signals efficiently. The developed method uses a coarse-to-fine hierarchical approximation that incrementally fits LIDAR signals up to a desired degree of accuracy. It is shown on three different signal types that the local analysis of the proposed method can eliminate noise more effectively than filtering and radial basis function based reconstruction of a signal provides computational efficiency compared to wavelet decomposition.","PeriodicalId":427580,"journal":{"name":"2016 IEEE International Conference on Intelligent Rail Transportation (ICIRT)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122065754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental results show that under strong wind conditions, the “car-swaying” phenomenon happened when EMU passing through the transition zone of wind proof structures or mutation zones of landform, whilst parameters such as roll angle of car body and lateral displacement of the center of gravity position change significantly. Under this described test conditions, there was no obvious function law between maximum value of roll angle, lateral displacement of center of gravity position, speed of EMU as well as ambient wind. The maximum values of roll angle and lateral displacement of the center of gravity position of the head car are significantly higher than the corresponding values of the tail car. Among all the typical windproof structures, roll angle of car body and lateral displacement of the center of gravity position have the largest maximum values when EMU running in cutting, which shows the worst windproof effect.","PeriodicalId":427580,"journal":{"name":"2016 IEEE International Conference on Intelligent Rail Transportation (ICIRT)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132996531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The line will follow GOA4 requirements according to IEC62290-2014 and IEC62267-2009. The main difference between the AUGT line and existing line is no driver or attended people on the train. The system will realize the following functions: Ensure safety movement, Driving Supervising guideway, supervising passenger transfer, Operating a train and Ensuring detection and management of emergency situations. Traditionally, HAZOP (Hazard Operability analysis) or FMEA (Failure Mode and Effect Analysis) method will be used to do the hazard analysis. But the main challenge is that most of human operation and behavior are replaced by equipment in AUGT and it is very difficult to deal with emergency condition. Finally, an operational scenario based method has been used to do hazard analysis which combined with STPA (Systems-Theoretic Process Analysis). As we know, STPA is a systematic analysis method from the view of safety control and it is good at human related error and management related analysis. In this paper, STPA has been used to compare with traditional method. The conclusions are: 1) STPA is more focusing on the safety related interaction and we can easily find the main clue by safety constraints compared to HAZOP; 2) Process Model Analysis should be done in each of scenario in order to find detail safety control measures; 3) In order to identify what could cause the unsafe control action or how control actions may not be executed properly, we also can use low layer control process model to do STPA analysis if we find it is still complex. We can regard this means as nested control process model.","PeriodicalId":427580,"journal":{"name":"2016 IEEE International Conference on Intelligent Rail Transportation (ICIRT)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129417591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
