  - Bulletin of the Polish Academy of Sciences-Technical Sciences - Rok 2011

  W artykule przedstawiono algorytm detekcji obrazu oraz jego realizację sprzętową w technikach FPGA i ASIC. Algorytm ten dedykowany jest do detekcji ruchu pojazdów i jest realizowany w czasie rzeczywistym. Użyto pojedynczą, umieszczoną na stałe kamerę monochromatyczną o niskiej rozdzielczości. Wykonywane są również operacje eliminacji cieni i rozjaśnień obrazu. Nachodzenie obiektów na siebie nie jest brane pod uwagę. Realizacja...

• The Impact of Weather on Traffic Speed in Urban Area

  Publikacja

  • J. Chmielewski
  • M. Budzyński

  - IOP Conference Series: Materials Science and Engineering - Rok 2019

  The issue of the impact of weather conditions on trip speed of vehicles has been studied for a long time and it is still the subject of many scientific researches. The impact of atmospheric conditions on the speed with which drivers drive their vehicles seems to be obvious. Good weather conditions, sunny weather with good visibility surely provokes higher speed while rainfall, wind...

  • M. Szczodrak
  • A. Czyżewski

  - Rok 2018

  Assessment of road traffic parameters for the developed intelligent speed limit setting decision system constitutes the subject addressed in the paper. Current traffic conditions providing vital data source for the calculation of the locally fitted speed limits are assessed employing an economical embedded platform placed at the roadside. The use of the developed platform employing a low-powered processing unit with a set of microphones,...

• Analysis of the regenerative braking process for the urban traffic conditions

  Publikacja

  • J. Kropiwnicki
  • M. Furmanek

  - Combustion Engines - Rok 2019

  In a regular drive system, with an internal combustion engine, vehicle braking is connected with the unproductive dissipation of kinetic and potential energy accumulated in the mass of the vehicle into the environment. This energy can constitute up to 70% of the energy used to drive a vehicle under urban conditions. Its recovery and reuse is one of the basic advantages of hybrid and electric vehicles. Modern traffic management...

• Identification of regions of interest in video for a traffic monitoring system

  Publikacja

  • G. Szwoch
  • P. Dalka

  - Rok 2008

  A system for automatic event detection in the camera image is presented in this paper. A method of limiting a region of interest to relevant parts of the image using a set of processing procedures is proposed. Image processing includes object detection with shadow removal performed in the modified YCbCr color space instead of RGB. The proposed procedures help to reduce the complexity of image processing algorithm and result in...
