ROAD TELEMATICSRedRail – System for traffic violationmonitoring at railway level crossings• Video-detection of lightsignalling• Licence plate recognition• Possibility of traffic accidentreconstruction from videorecording• Wireless data transmission• Technology independent onrailway equipmentGeneral DescriptionRedRail is an automatic system fordetection and archiving of trafficviolations primarily at railway crossingsequipped by the level crossingsystem with light signalling. Systemoperates on basis of vehicle licenceplate recognition.The main function of the systemis a detection of vehicles passingthrough level crossing duringflashing of the red light or a videorecordingof an accident. Because ofmodularity of the AŽD Praha camerasystem it can be used also for otheruseful functions like for instanceSystem graphic interfaceacquiring statistical traffic orienteddata or searching for stolen vehicles.Basic Technical DescriptionSystem consists of four CCD camerasand computer for evaluationof the video picture in the real time.Next parts are infrared reflectors foreasy vehicle detection in a miserableweather and at night.System is activated by the red lightof the level crossing warning board.Then a situation withdetection of passingvehicle licence platesis video-recorded.The recognisedregistration plateswith data, time andlocation of trafficviolation along witha picture are storedinto a database. Thenthey are coded andtransmitted via GSMtechnology to the dis-patcher‘s workplace for additionalprocessing.Deployment of the RedRail systemdepends on a current situation. Ingeneral, cameras along with infraredreflectors are installed at a separatepost ensuring a good view of a situationat the level crossing. Systemdoes not require any coupling withrailway systems and therefore it istechnologically completely independent.Camera signal is transmitted overa metallic line. In case signal distortionby induced voltage is impending(for instance near trolley lineor a tram line) the transmission isprovided over a fibre optic cablewith signal optical converter.www.azd.cz
