As Poslovni Dnevnik writes on the 30th of October, 2020, Croatian Roads will install 1,088 new digital cameras along its entire motorway network as part of the project for the reconstruction of the video surveillance system and video detection system, the value of which is around 41 million kuna.
Croatian Roads’ supercameras, boasting an impressive video detection system, can detect extraordinary situations on the motorway in mere seconds, such as people driving in the opposite direction, a stopped vehicle or a vehicle moving too slowly, writes Vecernji.hr.
Croatian Roads explained that more and more vehicles on the country’s motorways are creating a real need to increase overall traffic safety over them. At the same time, most emergency situations on motorways tend to occur in the zones of junctions. In order to prevent the possible consequences of emergencies on motorways, Croatian Roads pointed out, it is necessary to detect them in time and with the help of variable traffic signals to transmit messages to traffic participants and warn all competent intervention services in a timely manner. Therefore, a system of video surveillance and video detection has been introduced on motorways, which performs the constant monitoring and analysis of traffic conditions. The new cameras are being placed in locations where there is the greatest possibility of incidents.
They explained that in their operational centre, in addition to monitoring the traffic situation at all times, the weather conditions on the route are monitored and the necessary measures are taken in case of emergencies or worsening meteorological conditions. Effective emergency management depends entirely on the rapid detection and verification of incidents. With every minute lost, the risk of another, secondary accident caused by the initial incident increases dramatically. Every second employed in resolving the initial incident situation is important, they explained, adding that the effective management of emergency situations can save lives, and the reaction itself is most dependent on the rapid detection and verification of incidents.
Advanced automatic incident detection technologies, according to Croatian Roads, detect all significant incidents within seconds, and the result is mitigation of the consequences of the incident and the avoidance of secondary accidents. Traffic data, compressed images and alarms are sent to the control room. And the system can, as they explain from Croatian Roads, be integrated to serve as a trigger for other systems, such as traffic lights, variable traffic signs or information displays.
”When generating an alarm, the reference operator in the control room receives not only the alarm signal but also the visual information by recording the event itself and thus decides on the necessary actions in the most informed way possible. Real-time analysis of camera images enables more efficient management of traffic on highways,” the Croatian Roads experts explain.
In case of emergencies, they added, their timely detection enables the quick intervention of the competent services, and other traffic participants can be notified in a timely manner in order to avoid secondary accidents. In the existing video surveillance and video detection system on HAC motorways, there are problems with camera optics, output signals, low resolution, and the cameras don’t have the appropriate zoom or detail review.
Digital instead of analog
Therefore, in accordance with modern technological standards from the security and traffic information aspect, Croatian Roads started the process of the reconstruction of the existing video surveillance and video detection systems. Last year, they prepared the implementation and project documentation which envisaged the replacement of these older analog cameras with modern digital IP cameras and the installation of additional digital cameras in locations where it is currently not possible to meet the requirements of automatic incident detection.
Croatian Roads stated that IP cameras or Internet Protocol cameras are digital video cameras that transmit videos over a computer network. They have better image quality, advanced recording technology and the ability to connect a large number of cameras to a surveillance system. In addition, HAC explained, digital cameras have advanced features such as analysis, advanced motion detection technology and remote focusing. Videos are stored digitally, using network video recorders.
”Through various projects, Croatian Motorways is continuously carrying out activities to increase safety levels on motorways. Although we recently received a high rating for safety on motorways, our investments in safety continue, as shown by this project of the modernisation of the video surveillance system,” said the President of the Management Board of Croatian Roads, Boris Huzjan.
