It is important to guarantee the safety of train control system. Safety testing is an effective method to detect the safety holes and bugs in the system. However, because of the special characters of train control system like diversification, structural complexity and multiplicity of interfaces, most safety testing for train control system are manually executed based on specialistic experience, which leads to a huge testing workload. Besides, manual generation will easily cause the problem of missing test cases. In this paper, a model-based safety test method is introduced. We select a core function of onboard system as the representative to study the method. This function was analyzed by Fault Tree Analysis (FTA) to get the bottom events, which are used to turn to fault models being injected into the whole system model, affected system safety, and a set of timed automata network model of the core function is built using the tools of UPPAAL. Then COVER, the real-time test case generation tool, is used to generate the safety test cases from the system model (included fault models) automatically, and states transition criteria is customized based on preferences to achieve user-defined test, the test accuracy and efficiency is improved.","PeriodicalId":163655,"journal":{"name":"2013 IEEE International Conference on Intelligent Rail Transportation Proceedings","volume":"47 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":"129926708","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}

Capacity planning requires knowing how the mixture of signaling systems affects capacity. Different signaling systems have different operating characteristics including headway, end of movement authority and braking point. Heterogeneity of signaling systems using in a railway line usually reduces capacity. In this paper, Blocking time model was used to exposit the headway of signaling systems as well as the headway between trains which are running in different signaling systems. Simulation software Railsys was used to analyze the effect on capacity when trains are in different signaling systems sharing a line of Beijing metro. Analyzes included the effect of the continuous transmission-based signaling system (moving-block), the spot transmission-based signaling system (fixed-block) and especially their mix as well as the effect of the percentage of mixture and sequence of trains in different signaling systems. The effect of relationship between capacity and the mixture and sequence of trains was also evaluated as well. These analyses attempt to provide a better understanding of how the signaling systems affect railway capacity and a complete understanding of one factor on capacity. Furthermore, the results can help planners verify if the urban transit lines satisfy the capacity demand and adjust timetable arrangement.","PeriodicalId":163655,"journal":{"name":"2013 IEEE International Conference on Intelligent Rail Transportation Proceedings","volume":"56 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":"127175710","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}

DAS provide advice to driver aiming for optimized traffic flow and energy efficient driving. Based on real-time data communication between trains and train control center in combination with a centralized system for calculation of optimal train movements, CATO (Computer Aided Train Operation) offers a state-of-art connected DAS allowing trains to run as efficiently as possible considering the overall traffic situation on a railway line. In order to develop a successful DAS, the requirements for practical operation have to be carefully evaluated and clearly understood before implementation. CATO has been successfully deployed in Sweden and won the UIC Innovation Award for sustainable development. This paper will describe our experiences of important factors needed to achieve a successful DAS deployment, such as human-machine interaction issues, motivation factors, efficient communication and cooperation between train driver and dispatcher, good maintenance tools and continuous evaluation of the system performance.","PeriodicalId":163655,"journal":{"name":"2013 IEEE International Conference on Intelligent Rail Transportation Proceedings","volume":"6 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":"127802969","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 membership functions and symptom-fault mapping relationship for CTCS-3 fault diagnosis system are obtained from pre-measured experimental data as well as experts' diagnostic experience/knowledge to distinguish the effect of true fault from various factors. The cores dangerous of train control system are supervision and protect against exceedance of safe speed distance and driver exceeds safe speed distance, according the two safety links, first of all, set up fault tree; and then convert to Bayesian network, finally the fuzzy Bayesian network diagnosis arithmetic of fault diagnosis system with accuracy is designed and presented.
