Emergency systems

Out of the telecommunication systems serving safe travel, emergency distress terminals were the first to appear at the roadside. They allow for directly contacting the call centre of the operating service in the case of accidents, technical errors or other circumstances that impair safe travel. Calls initiated from the emergency terminal are electronically logged in the call centre, so the time of the distress call and its content are appropriately documented. The system has the supplementary feature of a flashing light signal, which warns of potential accidents. The flashing yellow lights installed at the terminals can be regulated from the centre; if active it warns drivers that the upcoming 2–4 kilometre section is dangerous or that other obstacles demanding the reduction of speed or taking an alternative route are present.

Weather systems

The weather monitoring terminals installed at the roadside provide the operating staff with up-to-date information regarding the condition of the road surface and the most important weather parameters. The gathered data constitutes the fundaments of the traffic management system, while also serving to prevent slippery road surfaces. The system allows for combating slippery road surfaces in an environmentally friendly way, thus preserving the surrounding area.

Traffic enumeration systems

The traffic enumerating devices provide the operator the basic data which allows for the optimized scheduling of maintenance activities and preparing various statistics, as well as the operation of traffic management systems. The data elicited from the system make the effect of a novel traffic element measurable.

Video systems

The closed circuit video system installed at the roadside provides for direct, visual monitoring of traffic and the quick localization of accidents and traffic jams, as well as their cause. The cameras may be operated manually or automatically via computer. Upon installing the cameras the aspects of the largest visibility and the monitoring of dangerous road sections must be observed. As a result of a recent improvement to the electronic infrastructure along the motorways, you can find out what is happening right now on the high speed road network with the help of 58 webcams.

Communication technologies

The basic components of various local electronic systems installed at the roadside communicate with the central assessment and visualization units through various hardwire (copper/optic) or cordless media. The dispatcher on duty communicates with road workers and patrolling road controllers performing jobs in the area within the jurisdiction of the engineering bureau through an GSM-phone. It allows for an uninterrupted exchange between those driving the vehicles in the snow ploughing convoys.

Information systems

At certain points of the motorway, adjustable-content information boards and signs are available to inform the travelling public. Operators provide information about current traffic conditions several times a day through local radio stations.

Traffic management systems

The traffic and weather assessment systems provide for the identification of situations hazardous to the safety of traffic. In such cases digital information signs situated across the span of the road allow for the appropriate management of traffic through changeable graphic and written messages. This contemplative, intervening activity is supported by the traffic management systems, which integrate the traffic enumeration, weather and informative systems in the given region.
