The subject of the project is the construction of three and the reconstruction of six light signalling devices, including the solution of camera surveillance and public transport preferences. The project will modify the traffic solution of the intersections concerned, the development of dynamic traffic control SSZ and the function of preference of public transport vehicles when passing through intersections controlled by light signalling equipment. Furthermore, the subject of the project is the acquisition of traffic engineering software - software for modeling traffic IAD and VHD and video-analytical system.
