RuggedCom offers a variety of ruggedized communications solutions for the transportation industry. Our products are used in:

• Intelligent TransportationSystems (ITS) for projects implementing Advanced Traffic Management Systems in accordance with NTCIP requiring C2F and C2C communications.
• Rail applications utilizing Ethernet networks installed in wayside cabinets for control, signaling and video monitoring applications.

• NTCIP stands for National Transportation Communications for ITS Protocol
• NTCIP is a family of communications protocols and data definition standards that
  have been designed to accommodate the diverse needs of various subsystems and user services of the National ITS (Intelligent Transportation Systems) Architecture.
• NTCIP standards are intended to handle these needs in the two areas of C2F and C2C.

Center-to-field (C2F) communications.

• A traffic signal management system communicating with traffic signal controllers
  at intersections;
• A transit management system communicating with monitoring devices and passenger information signs on transit vehicles and at transit stations and stops;

Center-to-Center (C2C) communications.

• Two or more traffic signal management systems exchanging information (including second-by-second status changes) to achieve coordinated operation of traffic signals managed by the different systems and to enable personnel at one center to monitor the status of signals operated from another center;
• A transit system reporting schedule adherence exceptions to kiosks, to a transit customer information system and to a regional traveler information system, while also asking a traffic signal management system to instruct its signals to give priority to
  a behind-schedule transit vehicle;

ITS Applications – C2F and Legacy Devices

RuggedCom’s field hardened (i.e. exceed NEMA TS 2) serial device server (RS400) with integrated managed Ethernet switch allows connectivity to legacy serial traffic controllers
(e.g. 170) as well as Ethernet enabled devices such as 2070 controllers and video encoders. All data is then available over any of the 10/100Mbps Ethernet ports. The availability of 100Mbps fiber optical Ethernet uplink ports coupled with the availability of long haul fiber optics which can span 90km segments allows for the creation of topologies spanning hundreds of kilometers and connecting hundreds of intersections.

ITS Applications – C2F with Gigabit

RuggedCom’s field hardened (i.e. exceed NEMA TS 2) Ethernet switches with Gigabit uplinks residing in the traffic control cabinets interface to traffic controllers (e.g. 2070), video encoders, and other traffic control devices. The fiber optical Gigabit uplinks allow for the creation of a fiber optical Gigabit backbone in the form of a ring or mesh topology which can cover large areas spanning hundreds of kilometers. The Gigabit speed of the backbone allows for hundreds of encoded (e.g. MPEG 2) video streams to be brought back to the traffic control center.

Support for protocols such as IGMP Snooping and eRSTP allow for management of a large number of video streams and high-speed network fault recovery.

ITS Applications – C2C with Gigabit Performance

RuggedCom’s field hardened RSG2200 Gigabit Ethernet switch allows for the aggregation
at the control center of multiple fiber optical Gigabit backbones bringing back video streams and controller data from the field. The Gigabit fiber optical backbones are created via fiber optical Gigabit uplink ports from the field hardened RS900G Ethernet switches located in the curb-side traffic control cabinets. The availability of long haul and single-strand bidirectional fiber optics allows for the creation of topologies spanning hundreds of kilometers and connecting hundreds of intersections.
