However, the degree of automatic test generation and test coverage are big challenges in testing. Concerning these problems, two approaches are proposed to test the on-board module of an advanced satellite-based train control system model. The first approach is a model-based test generation technique based on Coloured Petri Nets (CPNs). The test model includes a behavioural module of the on-board subsystem model and two other modules for the application environments of the onboard subsystem model. The behavioural module and modules of application environments form a closed system. The expected output of a test case is extracted from a path of the reachability graph of the test model. Beside the CPN based approach for generating test cases, another model-based test generation technique is applied. This method uses a special Petri net dialect called Safe Place Transition Net with Attributes (SPENAT) to model the intended behaviour of the test object, the on-board subsystem model in this case. No environment of the test object has to be modelled, because of the possible input/output modelling with a SPENAT. Thereby, a SPENAT is an open system and its transitions can be triggered by external events with parameters (external data). The identification of suitable test cases is based on the construction of a (complete) prefix of the SPENAT model and the specified coverage criteria. With CPN based (closed system) and SPENAT based (open system) approaches, the verification of a railway operations control system model, such as the on-board subsystem model in this case, could be done by testing. At last, the results of both approaches are discussed and the advantages as well as disadvantages are illustrated.","PeriodicalId":163655,"journal":{"name":"2013 IEEE International Conference on Intelligent Rail Transportation Proceedings","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128004368","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}

This is supported by satellite based localisation systems (GNSS) like GPS which already provide large economical and operational benefits by supporting applications in transport like passenger information, energy saving driving or tracking and tracing. The application of satellite based localisation systems for information purposes is a valuated contribution for a more efficient operation of trains. If satellite based localisation can be used as mean of safe localisation in train control systems, higher benefits according a safer and more reliable operation can be expected. To enable the usage in this application field, the certification of the localisation unit according the valid normative background of railways is necessary. Traditionally, a development of a product in railways starts with requirements which are the base for the product development and the following certification process. For the approval of an application of satellite based localisation for safety relevant purposes in railways, an already existing system like GPS shall be used as localisation device and therefore as important data source and needs therefore to be included into the certification process because of no generic certification of GLASS being already available. This paper can be the base for an approval process enabling the certification of satellite based localisation in railways.","PeriodicalId":163655,"journal":{"name":"2013 IEEE International Conference on Intelligent Rail Transportation Proceedings","volume":"56 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132531291","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}

In order to overcome the disadvantages of fixed installations for positioning along the track, a modular on-board positioning system based on GNSS (Global Navigation Satellite System) is being developed in the German national research project PiLoNav. GNSS receivers provide absolute positioning information, whenever satellite signals are available. The measurement accuracy can be augmented using relative positioning with respect to a reference station, e.g. with RTK (Real-Time Kinematic) algorithms. Additional on-board sensors are integrated into a multi-sensor framework and can be used to increase both accuracy and reliability of the position information. Alternative sensor configurations can be examined within this framework in order to identify a solution for a cost-efficient positioning system which delivers values with high accuracy and reliability. The obtained positioning information will be provided to different applications on-board with the aim to increase the level of automation in different train driving tasks.","PeriodicalId":163655,"journal":{"name":"2013 IEEE International Conference on Intelligent Rail Transportation Proceedings","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123552088","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}

For the design of a satellite-based train collision early warning system, satellite navigation is involved to realize precise and reliable train locating with assistance from odometry and on-board inertial sensors. Due to the requirements of map assistance for one-dimensional track location results in the track coordinate, it is important to generate effective electronic track map for the TCEWS (Train Collision Early Warning System) equipments. According to system demands and operation scheme of TCEWS, the requirements and key issues for generating the electronic track map are analyzed in this paper. Based on the raw measurements of railway tracks, the methodologies of track curve reduction and track geometry determination are described with corresponding principles. Based on that, three indices are presented to analyze and evaluate the uncertainty from the map data processing. Results with practical track measurements and field tests in Wuhan-Yichang Railway are analyzed and discussed, which demonstrate the effectiveness and significance of the presented methods for TCEWS implementations.","PeriodicalId":163655,"journal":{"name":"2013 IEEE International Conference on Intelligent Rail Transportation Proceedings","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114959069","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}
