Method and system for rapid updating of traffic data
A technology of traffic data and data, which is applied in the field of data processing, can solve the problems of reducing the real-time and accuracy of road condition information, road condition information is of little reference value to users, and data processing speed is slow, so as to reduce the amount of real-time traffic data and improve The effect of speed and data volume reduction

Example Embodiment
[0038] Example one
[0039] The embodiment of the present invention provides a method for quickly updating traffic data, such as figure 1 As shown, the method includes:
[0040] Step 101: Filter real-time traffic data to obtain valid traffic data, the valid traffic data including at least vehicle coordinates, current time, vehicle speed, and driving direction;
[0041] There are many invalid data in the collected real-time traffic data. After filtering the collected real-time traffic data, invalid data can be filtered out, reducing the amount of data. The system only needs to process the retained valid traffic data And in the process of processing, there is no need to judge whether a certain real-time traffic data being processed is valid traffic data, which improves the efficiency of the system for data processing and shortens the time for the system to process data.
[0042] Step 102: According to the real-time average speed of the minimum road unit of the driving target road sectio...
Example Embodiment
[0048] Example two
[0049] The embodiment of the present invention provides a method for quickly updating traffic data, such as figure 2 As shown, this embodiment is a specific embodiment of Embodiment 1, and includes the following steps:
[0050] Step 201: Periodically receive real-time traffic data;
[0051] Generally speaking, a user terminal sends data to the system at intervals (30 seconds or 60 seconds). Although there are many user terminals, if the system is allowed to receive data whenever there is data, the system will have too much time to wait for data or receive single data again and again, which is obviously not conducive to the efficiency of the system in processing data Improvement. Therefore, in order to improve the efficiency of the system's data processing, the system's data source will send all the real-time traffic data received during this period to the system at intervals. Generally, the period is one minute.
[0052] Furthermore, in different time periods ...

[0083] Example three
[0084] The embodiment of the present invention provides a system for quickly updating traffic data, such as image 3 As shown, the system includes:
[0085] The filtering unit 11 is configured to filter real-time traffic data to obtain effective traffic data, the effective traffic data including at least vehicle coordinates, current time, vehicle speed, and driving direction;
[0086] There are many invalid data in the collected real-time traffic data. After filtering the collected real-time traffic data, invalid data can be filtered out, reducing the amount of data. The system only needs to process the retained valid traffic data And in the process of processing, there is no need to judge whether a certain real-time traffic data being processed is valid traffic data, which improves the efficiency of the system for data processing and shortens the time for the system to process data.
[0087] The matching unit 12 is configured to generate the short-term predicte...
