Abstract: A system and method for measuring a real traffic flow of an area use images of vehicles and pedestrians taken from the sky in time intervals of an area. The system and method also use continuous tracking data for vehicles and pedestrians, provided by navigator manufacturers, map providers, route applications or by phone carriers. Both images and continuous tracking data are combined and processed by a processor that applies image pattern recognition software to the images so that each vehicle and pedestrian in the images is recognized and labeled for which tracking data is available. The system identifies vehicles and pedestrians contained in both databases and applies a weight to thereto. Accordingly, the system and method are able to estimate the traffic flow and the total number of vehicles and pedestrians for a particular time and area.

Abstract: According to the invention, the system automatically locates effective visibility zones from which an element to be viewed is visible. For this purpose, for this purpose, the inventive system makes use of the location of potential visibility zones (obtained from data such as sitting, morphology and orientation of the element to be viewed, potential visibility distance assigned to said element, etc.) and the morphology of the region in which the effective visibility zones are to be located. Said system avails of means of appraising the degree of visibility of different visibility zones according to the level of compliance achieved in relation to the criteria for locating visibility zones.
