 The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

 An embodiment of the present invention provides a method for processing road traffic event information. As shown in FIG. 1, the method includes the following steps:

 511. Obtain a quality parameter of the road traffic event information.

 512. Acquire a corresponding specific threshold according to a preset setting.

 513. Compare the quality parameter and the specific threshold, and determine, according to the result of the comparison, whether the quality indicator of the road traffic event information is qualified, and the quality indicator includes information timeliness, information correctness, information integrity, and collection stability. At least one of the sexes.

The processing method provided by the embodiment of the present invention determines the quality indicators of the collected road traffic event information by comparing the quality parameter with the specific threshold, and can obtain the quality of the road traffic event information collected in a certain period of time. The obtained quality conditions can provide improved reference for subsequent information collection, improve the quality of collected real-time traffic event information, and give greater play to the positive effects of road traffic incident information. Since the road traffic event information of the user to be sent to the intelligent transportation system should be timely and complete, and accurate, the processing method provided by the embodiment of the present invention can determine the quality indicator including the information timeliness of the collected road traffic event information. At least one of information correctness, information integrity, and collection stability can obtain four quality indicators of information at the same time, and one or several quality indicators can also be obtained, and the quality indicators that need to be obtained can be selected according to actual requirements. Of course, the quality parameters acquired in step S11 and the specific thresholds acquired in step S12 are different corresponding to different quality indicators.

 Generally speaking, in the field of intelligent transportation, road traffic incidents are divided into quality levels according to the road level, event type and duration of the place of occurrence. The road traffic events of different quality levels may have different information quality due to different factors involved. Different, therefore, the step S12 can be performed in two steps, first determining the quality level of the road traffic event information, and then acquiring a specific threshold corresponding to the quality level according to a preset, each quality level corresponding to each quality The specific thresholds for the indicators are different. Table 1: (h: hour, m: minute, d: day)

Figure imgf000006_0001
The quality level adopted in the embodiment of the present invention is divided according to the road level, the event type, and the continuous period (the time elapsed from the start of the event to the end of the event) at the place where the road traffic event occurs, and the road traffic event is divided into A/B. /C three quality grades, of which the road grade includes intercity highway RTIC1, urban high, express trunk RTIC2, urban trunk road RCITC3 and other roads RTIC4 level 4, event types including traffic control, traffic time, construction work and roads Obstacles, continuous periods include long periods, medium periods, and end periods.
