11. The results of project

12. Application in the field of junction control functional compatibility with usual detectors ­sensitivity, hysteresis of detection ­compensation of presence, holding time interface unit, compatible with usual detector cards the speciality of the developed system: ­simultaneous detection of vehicles and pedestrians ­detection depending on dierction of movement ­detection only of starting pedestrians

13. Application in the field of traffic data acquisition the realized altorithms result directly most of derivative informations ­vehicle categories ­length ­width, heigth ­speed ­queue length the speciality of the developed system: ­collection of video information ­picture transmission to the processing centre (in case of on- line connection)

14. Application in the field of special traffic influencing systems direct detection on special incidents, not locally ­changing lanes, movement in wrong dierction (handling the velocity as vector) ­standing vehicle, strange object on the road (speed measurement) ­presence in bus lane (vehicle classification) the speciality of the developed system: ­storage of picture series documenting the circumstances of incident

15. General features of the applications the installation doesn’t need to break up the pavement the system is adatable to existing infrastructure along the road ­ it can be mounted on existing poles ­universal adapter, fixing with steel ribbon ­algorithms for compensation of vibration architecture based on distributed intelligence ­the results of preprocessing can be transmitted with use of relatively narrow band width
