LA Metro Regional Corridor Connector “Simplicity through Complexity”
The LA Metro (METRO) Regional Corridor Connector is METRO’s most complex Radio System. The Regional Corridor will bring the most diverse rail lines, the highest volume of trains in the shortest headways in the METRO system. The radio system will add in the most channels and require the most redundancy, both add complexity to the design. CTI is the Engineer of Record (EOR) for the Regional Corridor Connector, working for the Prime Contract on this design build project.
CTI designed a dual headend system with geographic, headend and equipment N+N redundancy. CTI’s Network Management System (NMS) is designed to provide control and monitoring, the NMS allows for instantaneous main to back up switching of the head-ends, redundant equipment and fiber paths in the system. The NMS monitoring and adjustment of the equipment at the individual hardware level, allows operations and maintenance personnel to assess and address maintenance issues before dispatching field resources.
The complexity of the design allows for simplicity of operations and maintenance, major alarms can be addressed through redundancy and issues can be evaluated online and resources can be assigned to address now minor issues that no longer effect system operations.
CTI has been working with METRO since 90’s, completed design and integration projects in METRO’s Red, Blue, Green and Yellow lines and as part of the Regional Corridor project will oversee the second retrofit of the 7th/Metro hub, the first retrofit was in 1999.
