The invention provides a vehicle-mounted unit-roadside unit free flow charge mode transaction method. The method successively includes that a process that the roadside unit initiates simultaneous coordination with a plurality of vehicle-mounted units about mutual communication parameter and configuration, a process of transmitting and reading of transaction data information frames, and a process of sending of recorded reports. The method is good in compatibility, good in expansibility, and capable of meeting the requirement of concurrent processing of multiple offshore banking units (OBU) of city road and bridge free flow transaction charge.
Description
technical field [0001] The invention relates to a technical scheme of an OBU-RSU free-flow charging mode based on the application of free-flow electronic toll collection on urban roads and bridges in the application field of urban intelligent traffic. Background technique [0002] At present, the urban road and bridge free-flow tolling technology is one of the most advanced road and bridge tolling technologies in the world. It is a fast electronic toll collection system without any toll roadblocks. This kind of charging system has been quite mature in some developed countries, but due to the great difference between China's application market and foreign application markets, there will be certain risks in directly using the existing international mature technology; It is still in the research stage and there are no application cases yet. [0003] Electronic Toll Collection (ETC) is an automatic toll collection system for roads, bridges and tunnels that is being developed a...
