Embodiment Construction

[0037] A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

[0038] In order to enable traffic signs to convey digitalized road traffic sign information to digital intelligent transportation vehicles and equipment, an embodiment of the present invention proposes an information processing and analysis method for digitalized traffic signs, which includes:

[0039] The data transmission step is used for real-time communication between the digital traffic sign and the intelligent traffic terminal equipment;

[0040] Since the data transmission between the digitized traffic sign and the intelligent traffic terminal in the embodiment of the present invention does not require high reliability of the transmission, and the amount of data transmission is not large, the CRC cyclic redundancy check is used in the data transmission in the embodiment of the present invention. Check the integrity of the data using a data check ...

Abstract

The embodiment of the invention provides a digital traffic sign information processing and analyzing method. The method comprises steps: a step of digital traffic sign data transmission in which the digital traffic sign transmits stored data to an intelligent traffic terminal, wherein the data at least comprise the information content S<c> of the digital traffic sign itself and an initial parameter set P<s> of the traffic sign, a step of data verification in which data verification is carried out after the terminal receives the data to judge the effectiveness of the data, the next step is carried out if passing the verification, otherwise, the step is ended, a step of data matching in which the terminal enables the received data to be matched with the vehicle basic information set B<v> andthe vehicle real-time dynamic information set D<v> stored in the intelligent traffic terminal, and a step of rule determination in which a rule S<v> corresponding to the vehicle is determined.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to an information processing and analysis method of digital traffic signs. Background technique [0002] With the development of human society, transportation has become the most basic need of people's life. Whether it is cargo transportation or people's travel, it is inevitable to use the transportation system. As cities continue to expand, traffic problems have become the most typical "big city disease". [0003] Existing traffic signs are all static traffic signs, which generally stand on both sides of the road or extend to the top of the road through beams. This kind of static traffic sign is very effective in indicating constant conditions, such as road names and so on. This kind of static traffic sign is made by using graphics, symbols, lines, text, etc. of specific colors to convey standardized visual information to people. In other words, traditional ro...
