Patent number: 12037034Abstract: A method and system for managing guided vehicle traffic over a railway network include a first ATS system regulating guided vehicle traffic over a first regulation domain and a second ATS system regulating guided vehicle traffic over a second regulation domain. The first and second regulation domains have a common boundary. The first ATS system sends, to the second ATS system, configuration and circulation data for a part of the first regulation domain, for regulating guided vehicle traffic on the part according to a set of regulation data from the second ATS system. The second ATS system determines, from received configuration and circulation data, regulation data for an extended regulation domain including the second regulation domain and the part and for sending to the first ATS system the set of regulation data regulating the guided vehicle traffic on the part of the regulation domain of the first ATS system.Type: GrantFiled: March 10, 2022Date of Patent: July 16, 2024Assignee: Siemens Mobility SASInventors: Marius Traian Indre, Thierry Bouchet

Publication number: 20220289260Abstract: A method and system for managing traffic of guided vehicles over a railway network include a first ATS system for regulating traffic of guided vehicles over a first regulation domain of the network and a second ATS system configured for regulating traffic of guided vehicles over a second regulation domain. The regulation domains have a common boundary and at least one track connects a first position within the first regulation domain to a second position within the second regulation domain. The second ATS system detects limited traffic capacity at the second position and automatically computes, as a function of the detected limited traffic capacity, a target headway between two successive guided vehicles crossing the common boundary for entering the second regulation domain. The first ATS system automatically determines, from the received target headway, a reference timetable, complying with the received target headway, for the first regulation domain.Type: ApplicationFiled: March 10, 2022Publication date: September 15, 2022Inventors: Marius Traian Indre, Thierry Bouchet
