Urban expressway traffic information acquisition system

Abstract

The invention discloses an urban expressway traffic information acquisition system, which comprises a data acquisition unit, a data management unit, an information processing unit, an integrated interface unit, a user application unit and a decision management unit, wherein the data acquisition unit is used for acquiring, gathering and disposing widely distributed multi-source heterogeneous mass traffic data, and the data management unit is used for distributed storage, inquiry, backup and cleansing of the data; the information processing unit is used for cleaning, analyzing and filtering the heterogeneous data to form an information item meeting the standard, and an integrated interface is used for providing standard information to a requester; the user application unit is used for publishing or acquiring the standard information through the relevant interface on a web page, deciding past paired data, disposing, analyzing and providing decision; through cloud computing, the data exchange of the national intelligent transportation system, and system interworking, interconnection and interoperability are realized by big data processing.

Description

Technical field [0001] The invention relates to the field of intelligent transportation, in particular to the collection and management of urban expressway traffic information in an intelligent transportation system. Background technique [0002] The urban expressway is a fully enclosed, all-overpass urban road system with motor vehicles as the main service object, constituting the main road network of urban traffic. Although the expressway has the characteristics of better road conditions and driving environment, less interference by non-motor vehicles and pedestrians, faster driving speed, and stronger regularity than ordinary urban roads, the distance between entrances and exits is small, and the frequency of vehicles entering and exiting is high. Frequent intersections near the entrances and exits, which interfere with the normal driving of the main road, and are prone to blockage. At the same time, expressways are closely related to ordinary urban roads. The expressways pas...

Problems solved by technology

[0003] At present, some products have been produced in China for the monitoring of expressway traffic information. However, because the intelligent traffic information collection systems that have been built in various places are developed by different manufacturers and based on different technical routes at different times, the data collection and access methods are different. They are relatively independent among each other, resulting in the status of each established system in the state of information islands, poor information communication, and difficulties in data integration and sharing; road intelligent traffic information collection is still dominated by urban ground roads or expressways, and urban expressway traffic information collection systems Less, this kind of system has the disadvantages of single function, lack of integration, backward technology, etc.

It is mainly reflected in the scattered construction of application systems, lack of effective integration of massive data, low utilization rate of traffic data, failure to fully utilize the value of data, limited dissemination of traffic warnings, and difficulty in obtaining road condition information in a timely manner, etc.
