Various initiatives are taken to increase the road capacity and safety by making the roads "more intelligent" by implementing motorway management systems for routine and unplanned events. Such an ITS system has several components and relies on a high capacity communications backbone for transfer of information to and from individual monitoring devices and sensors.

Typically ITS applications include Variable and Changeable Message Signs (VMS and CMS), Ramp Metering, Traffic Control Signals, Over-Height-Detectors (OHD), CCTV including fixed cameras and Pan Tilt Zoom (PTZ) cameras, and Emergency phones.

Also in tunnels, a diversity of applications are present, such as CCTV, SCADA, PBX, public addressing, intercom, fire detection and access control.

OTN supports all these applications on a single backbone, with bandwidth ranging from 150 Mbps up to 10Gbps, thereby assuring easy system upgrades taking care of future motorway growth.

Its double ring structure and redundant power and optic modules provide a highly resilient communication system.

OTN saves installation space and effort, it is cost efficient to implement, offers guaranteed QoS, is resistant to heat and dust, and offers a variety of network topologies. Take a look at the benefits of an OTN.
