Definitions
- Monitoring changes in the traffic situation can advantageously be achieved if, after taking an image of the area, at least one further image of the same area is taken and also evaluated with regard to vehicle densities in the area, and if at least two taken images are compared with one another ).
- a direct optimization of the control algorithms of traffic control systems and traffic light phases can be realized by a comparison before and after the optimization measure.
- changes made by road construction measures can advantageously be checked and existing simulation programs can be precisely coordinated.
- Information obtained about a traffic condition in the area is used for further use, preferably in the form of data that is only relevant for this use and preferably in a use device provided for this use (claim 17).
- a use device provided for this use (claim 17).
- different use devices can be used, which are preferably and in particular stationary on the earth's surface. The invention is explained in more detail in the following description using the figures as an example. Show it:
- FIG. 2 shows an image section from an image of the region of the earth's surface, which is photographed from an artificial satellite orbiting the earth
- Figure 6 shows an exemplary arrangement for detecting a traffic condition.
- a body 2 is located at a distance a above the earth's surface 1, from which an image of an area 10 is recorded which is located below the body 2 on or in the air space above the earth's surface 1.
- the body 2 can be an earth satellite or an aircraft.
- U.N- ter Earth surface 1 is to be understood not only the surface of the mainland but also the water surface of the earth.
- the image 3 taken with the radar radiation 5 and thus the image section 11 'according to FIG. 5 have, compared to the photographically taken picture 3 and thus the image section 11' according to FIG on.
