Opis:: This paper presents an idea of development of the OnDynamic system used for non-invasive and low-impact measurements and visualisation of traffic parameters. Planned development would introduce new functionality to the system which allows to observe road traffic impact on the air quality and acoustic climate in a specified area. Network of sensors will be complemented with base stations equipped with the noise sensors, as well as sensors that allow to measure the concentration of the pollutants in the air.

Opis:: Mobility is one of the basic needs of today’s people. The amount of motor vehicles is ever increasing because of this. Hence there is more and more traffic load on every road, especially in and around urban areas. The maximum capacity of those roads is more and more often reached during peak hours, traffic jams and long travel time is the result. In big cities with high vehicle traffic numbers, it is necessary to operate traffic data collection systems for the control center. One of the most compelling sensor class is the Bluetooth/WiFi-based traffic sensor, which is a non-intrusive and inexpensive alternative to LPR (License Plate Recognition) systems. BLIDS-sensors, mounted next to the road, detect unique BT/WiFi-IDs from devices such as mobile phones and navigation systems that come within the reception range of the sensor. This unique BT/WiFi IDs are made anonymous and stored together with highly accurate exact time stamps directly on the sensor before they are transmitted to the BLIDS-server system. From the information gathered from at least two sensors, real-time traffic information (e.g. travel-times, traffic jams, dwell time at intersections, origin/destination analysis as well as traffic flows) can be calculated. The BLIDS network provides a wide range of applications. It starts with the installation of mobile solutions to provide temporary measurements and ends with fixed installations. This paper examines the measures and preconditions that need to be fulfilled for a thorough usage of BLIDS sensors in strategic route management systems.

Opis:: Authors describe the possibilities of a wireless technology used within safety-critical applications with orientation to selection the computationally safety cryptography techniques. Undetected corruption of data transmission can cause substantially considerable damages within equipments, environments or demands on human health and this is reason why systems have to be designed so that guarantee required Safety Integrity Level. For this reason the safety-related wire or wireless machines must have implemented a number of safety mechanisms located into special safety or security profiles. Nowadays, after acceptation of the new standard ISA 100.11a the barrier was broken towards the use of wireless machine-to-machine communications in standard and safety-related communication, too. ZigBee technology is very accepted standard which fulfils the requirements to the wireless industrial communication system. The main part of the paper describes the possible attacks to ZigBee communications based on cryptography mechanisms with orientation to Denial-of-Service attack. The practical part contains the results of ZigBee sensor network testing in laboratory conditions with demonstration of error-control mechanisms of MESH topology and cryptoanalytic’s attacks based on monitoring of traffic are mentioned as well.
