A method and a device for detecting road users and obstacles on the basis of camera images, in order to determine their distance from the observer and to classify them. In a two-step classification, potential other parties involved in a collision are detected and identified. In so doing, in a first step, potential other parties involved in a collision are marked in the image data of a mono-image camera; their distance and relative velocity are subsequently determined so that endangering objects can be selectively subjected to a type classification in real time. By breaking down the detection activity into a plurality of steps, the real-time capability of the system is also rendered possible using conventional sensors already present in the vehicle.

The invention relates to a system and a method for addressing three problems:(A) generate a tollpath of consistent length by determining one of a possible set of paths which are all the same length in cell-count every time the same journey is taken,(B) determine a consistent price for each tollpath by setting pre-determined values on those cells such that every possible path variant of a specific journey produces the same toll, and(C) determine the correct price for each tollpath by adjusting prices in each cell to account for the exact distance actually represented (some roads pass through a cell parallel to the cell edges and some pass through at an angle) so that the toll calculated exactly matches the toll that would be calculated had the exact linear, analogue distance been measured on the actual road.

A road pricing smart client and method for a road pricing system enabling the removal of information from the positioning data describing the itinerary which suggest private data such as travelling speed and itinerary of the originator of the data. Accordingly, the smart client and method is configured to re-sample the original positioning points of the route into equidistant sections, remove timing information from the positioning data, slice the re-sampled route into slices shaped as those provided by other road users by employing a common “virtual grid”. By transmitting the slices in randomized order with an arbitrary delay, coherence of slices corresponding to formerly neighboring portions of the itinerary, are not correlated anymore. However, there is still enough information provided to the toll system to send an excerpt of the fee database allowing the smart pricing client or method to calculate the occurred fees.The main advantage of the smart client and method is that it delegates in a secure and privacy-preserving way the costly operations to the external toll server proxy. Thus, storage of digital maps in the client is not required, and tariff updates are only transmitted when necessary in a way that preserves privacy. Finally the data transmitted by the smart client can be preprocessed and compressed in order to remove all unnecessary personal information, thereby reducing the bandwidth requirements on the telecommunication network. Further, the proposed solution enables to raise statistics on road usage, i.e. traffic appearance by road-section without endangering privacy of the individual road users.
