For the effective implementation of this work, it requires constant monitoring and clear of all elements involved in the vehicular traffic in the city. This task was made for several years with independent information systems that did not permit a complete and fast display of all elements. Additionally they were not georeferenced. What made it difficult decisions for the operator to the large amount of information handled in this process. This paper presents an information system addition to integrate and synthesize all the information, it presents in a georeferenced map of Medellin. The new system show the location of the traffic agents, traffic incidents, the red light cameras, video analytics, The Weather Network Early Warning System of Medellin (SIATA), programmed road closures and variable message signals VMS, they allow a fast understanding of the events on ways, and therefore timely execution of procedures in transit operation. The system was implemented in Arcgis Online, in addition to the above benefits, was the benchmark and starting point in the implementation of the new traffic management center HERMES. The advantage geographical in handling information and decisions, it represents to the Control Center key benefits for circulation in terms of lower response times and traffic incidents in the dynamic and online guidance to users of the road network, finally resulting in the improvement mobility of the city.","PeriodicalId":255012,"journal":{"name":"2012 IEEE Colombian Intelligent Transportation Systems Symposium (CITSS)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115938898","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 basic concept is to take advantage of the energy generated during the braking process of trains, which is otherwise wasted and transformed into heat. A power system simulation was created as a tool to analyze the behavior of a stationary ultracapacitor bank connected to the Metro system. Ultracapacitor modules were dimensioned adequately, power electronic elements were adjusted and further a control system was established. Amongst others the simulation demonstrates the impact of varying the distance between ultracapacitors and traction power substation. Furthermore the dependency of the ultracapacitor's technical specifications on charging and discharging behavior is shown. The simulation allows a large number of parameters to be modified through the easy-to-handle user interface. A scientific method is provided to analyze ultracapacitor assisted regenerative braking of metropolitan railway systems. As an example the Metro of Medellín in Colombia is applied and rounded out by an estimation of economic viability.","PeriodicalId":255012,"journal":{"name":"2012 IEEE Colombian Intelligent Transportation Systems Symposium (CITSS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114589264","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}

Different solutions require different levels of telecommunications service quality. These parameters have to correspond with ITS service performance parameters required by specific service. Even though quite extensive range of wireless data services with reasonable coverage are provided by public telecommunications providers practically all services are provided with no guaranteed data service quality and security. ITS requirements can be better resolved if typically used public solution is combined with both other public as well as private services where and when it is needed. Such solution requires implementation of relevant flexible system architecture supported by the efficient decision processes. Paper is concentrated on the telecommunications security issues with dynamically changing wide area networking. Expected level of security depend on relevant ITS services requirements. It is well known fact that data volumes transferred both in private data vehicle on board networks as well as between vehicles and infrastructure or other vehicles significantly and progressively grow. Such trend leads to increase of the fatal problems appearance probability if security of the wide area networks is not relevantly treated. Probability of hazards appearances grow if vehicles networks are integrated in the dynamically organized wide area networks. That is reason why relevant communications security treatment becomes crucial part of the ITS telecommunications solution. Besides of available “off shelf” security tools solution based on non-public universal identifier with dynamical extension and data selection according to actor role or category is presented.","PeriodicalId":255012,"journal":{"name":"2012 IEEE Colombian Intelligent Transportation Systems Symposium (CITSS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130710925","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}
