Description
Technical Field
The invention relates to the technical field of traffic systems, in particular to a multiscale traffic information publishing system and method based on vehicle-road cooperation.
Background
The traffic information distribution service collects and processes real-time traffic state and traffic control information by a traffic manager or a traffic information service provider, thereby providing traffic control, traffic guidance and other services to traffic participants. For traffic participants, the traffic participants can be assisted in making reasonable traffic decisions by acquiring richer traffic information, and select appropriate traffic routes, so that the traffic travel time is reduced, and the traffic travel safety is ensured. The traffic information distribution service becomes a key technology for improving the capacity and the operation efficiency of a traffic system after the road network is saturated. The existing traffic information publishing system can publish information such as traffic flow acquired by a sensor and other traffic acquisition modes to traffic participants through audio broadcasting, a traffic information publishing website, an electronic map and the like.
However, the current traffic information distribution system for traffic information distribution service has a series of problems such as unclear distribution range, non-uniform data platform, low data standardization level, and low real-time performance. The method and system for issuing traffic information as proposed in patent CN101887640B do not specify the information issuing range, resulting in an ambiguous issuing range. The system and the method for releasing the real-time traffic information based on the fixed vehicle information acquisition, as proposed in the patent publication 201810071746.x, do not specify a data management platform, so that the data platforms are not uniform; all information is processed by the server, and the real-time performance of the information cannot be guaranteed. For example, the invention patent CN101520947B proposes a dynamic traffic information distribution method and device, the distribution content only has two states of "congestion" and "non-congestion" of the road, there is no numerical description on the congestion state, and the data standardization degree is low. When the system is oriented to a vehicle-road cooperative traffic system mainly based on intelligent networked automobiles in the future, the conventional traffic information issuing service cannot achieve the purposes of improving the traffic travel efficiency and ensuring the traffic safety. Therefore, a system and a method for issuing multi-scale traffic information based on vehicle-road cooperation are needed to ensure the continuation and effectiveness of traffic information service in the future
An effective solution to the problems in the related art has not been proposed yet.
