TRANSPORT OF DANGEROUS GOODS AND RISK MANAGEMENT 196 review <strong>of</strong> all subjects response to the accident: the relevant institutions, bodies <strong>and</strong> agencies, theiractivities <strong>and</strong> possibilities <strong>of</strong> engagement; overview <strong>of</strong> Network-road routes for <strong>transport</strong>, their detailed analysis <strong>of</strong> the geomorphologiccharacteristics <strong>of</strong> soil <strong>and</strong> terrain along the routes which hazardous materials are being <strong>transport</strong>ed(configuration <strong>of</strong> relief, character <strong>of</strong> soil, covers with trees, proximity to populated places,population, sources <strong>of</strong> drinking water, etc.) <strong>and</strong> Register review <strong>of</strong> all hazardous substances that are <strong>transport</strong>ed, with the physical-chemicalcharacteristics.5. Equipping vehicles that <strong>transport</strong> hazardous materials with adequate digital devices for global positioningwith auxiliary equipment.6. Connecting all subjects <strong>of</strong> response to the accident mutual with the Control center, provision <strong>of</strong> adequatecommunicational GPRS network, as well as in informatical connections with a unique database from thecenter.SYSTEM FOR AUTOMATIC VEHICLE TRACKING (AVT)System for automatic vehicle tracking allows remote control over cars <strong>and</strong> a centralized <strong>management</strong> <strong>of</strong> rollingstock using GIS, mobile network (GPRS service) <strong>and</strong> the Internet. It represents a sophisticated modular system thatuses GPS <strong>and</strong> various radio communication systems for data transmission.Primary components <strong>of</strong> the GPS tracking system are (Figure 1):GPS receiver (the receiver), with a unit for power <strong>and</strong> data transfer;Communication device (modem), GSM modem, radio or satellite transmitter;Communication service for the subject system for transferring data GSM/GPRS, <strong>and</strong>Control Center with installed user s<strong>of</strong>tware application, server <strong>and</strong> modem.The system provides detection, monitoring <strong>and</strong> communication from the base – the center with unlimited number <strong>of</strong>vehicles which are used to <strong>transport</strong> hazardous materials. Location <strong>of</strong> the vehicle is determined using a GPSreceiver installed in the vehicle that provides data on height, speed <strong>and</strong> the direction <strong>of</strong> movement which allowsmonitoring <strong>and</strong> reporting on each unpredicted situation, in real time. The GPS unit, which is built in every vehicle,receives signals from satellites, precisely determines the location <strong>of</strong> the vehicle via mobile network operators (GSM– Global System for Mobile Communication), <strong>and</strong> submits data to the center for automatic vehicle tracking. Theequipment installed in the vehicle carries “alarm” signals <strong>and</strong> the precise position <strong>of</strong> the vehicle to the Controlcenter through communication network. The transfer <strong>of</strong> data between the Control center <strong>and</strong> the vehicle is manlycarried out through GSM mobile telephone network using a data channel <strong>and</strong> SMS/GPRS service. Also the driverwhile driving can identify the current position <strong>of</strong> his vehicle on the display <strong>of</strong> a laptop or a PDA device.The system for automatic vehicle tracking works in this way, the GPS receiver calculates (using triangulation) itslocation based on the data which in the given (programmed) time intervals, obtained from GPS satellite (for 2Dposition a “contact” with 3, <strong>and</strong> for 3D with 4 satellites is sufficient). Besides the correct position, the GPS receivercalculates a number <strong>of</strong> other parameters: speed, direction <strong>of</strong> movement, path, given length <strong>of</strong> the route distance to agiven destination, etc. When you want to transfer data about the position <strong>of</strong> the object, the control center, throughcommunication service, takes data from the communication device (modem) connected to a GPS receiver in amobile object. If the GPS is under power <strong>and</strong> if it “sees” satellites, the exact position <strong>and</strong> other information aredownloaded in real time.
