Supporting the monitoring services reliability in transportation systems – antropo-technical approach

Process of ensuring the security of citizens, objects and material goods requires access to the information from sensors located in diff erent points of monitoring and data acquisition systems. Th ey are a widely used in administration of carfleet or the visualization of selected functions of transport processes. However, transmission of data from multiple video sensors may lead to the degradation of video quality and even to lack of identification capabilities. As a result, the overall service reliability can be decreased. The process of the system exploitation can determine the reliability of the video monitoring services as well. This process includes the technical object (hardware and soft ware) and the man (operator) who exploits the system under certain environmental conditions (external and internal) and represents so called antropo-technical approach in which the operating requirements are taken into consideration (particularly related to reliability). The paper presents components elaborated for maintenance of reliable video monitoring services as well as the results of selected tests showing its efficiency. Proposition of comprehensive metrics for assessing the reliability of exploitation of video monitoring system, which takes into account antropo-technical approach is presented as well.
