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...

Embodiment Construction

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0023] Combine figure 1 As shown, the urban expressway traffic information collection system software disclosed by the present invention includes a data collection unit, a data management unit, an information processing unit, an integrated interface unit, a user application unit, and a decision management unit.

[0024] The data collection unit collects, aggregates, organizes and stores the collected traffic big data in a database. The information collection of the traffic big data mainly includes traffic flow information, traffic condition information, vehicle violation information, weather information, number of vehicles, and vehicle speed. , Vehicle type and headway and other information, where the traffic flow is the number of vehicles passing a certain point in a certain period of tim...
