Increasing of the urban traffic surveillance by automatic information device

Our work consists in the development and setting of an electronic information panel designed to monitor road traffic informational characteristics (velocity, vehicle length and flow density). This information is available using two displays installed above the monitored traffic line. Wishing a “just in time” warning for the driver, the display of the instantaneous speed was represented by the green light if it falls within the legal speed and red light if it is over the legal speed. Our aim was to develop an informing, monitoring and data storing equipment, able to record the time, the speed and the length of crossing vehicles. A test version, which consists of three main modules: the detection module, a programmable controller and an information panel, was designed and a complex hardware and software equipment was manufactured. The efficiency, reliability and stability in operation were the chosen criteria for the detection module. The programmable controller processes the data collected from detectors and displays it. In the future, the hardware platform will allow the connection to other devices (eg. GPRS modem), aiming to achieve the possibility to operate independently or integrated into a system of remote macro-monitoring (idea for further development).
