Embodiment 1

[0039] Embodiments of the present invention provide a method for quickly updating traffic data, such as figure 1 As shown, the method includes:

[0040] Step 101, filtering real-time traffic data to obtain valid traffic data, the valid traffic data at least including 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, the invalid data can be filtered out to reduce the amount of data. The system only needs to process the retained valid traffic data In addition, there is no need to judge whether a certain real-time traffic data being processed is valid traffic data during the processing process, which improves the data processing efficiency of the system and shortens the data processing time of the system.

[0042] Step 102, according to the real-time average speed of the smallest road unit of the traveling target road section a...

Embodiment 2

[0049] Embodiments of the present invention provide a method for quickly updating traffic data, such as figure 2 Shown, this embodiment is the specific embodiment of embodiment one, comprises the following steps:

[0050] Step 201, receiving real-time traffic data periodically;

[0051] Generally speaking, a user terminal will send data to the system every interval (30 seconds or 60 seconds). Although the number of user terminals is large, 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 data processing by the system, the data source of the system will send all the real-time traffic data received during this period of time to the system at intervals. Typically, the period is one minute.

[0052] Furthermore, in different t...

Embodiment 3

[0084] Embodiments of the present invention provide a system for quickly updating traffic data, such as image 3 As shown, the system includes:

[0085] A filtering unit 11, configured to filter real-time traffic data to obtain valid traffic data, the valid traffic data at least including 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, the invalid data can be filtered out to reduce the amount of data. The system only needs to process the retained valid traffic data In addition, there is no need to judge whether a certain real-time traffic data being processed is valid traffic data during the processing process, which improves the data processing efficiency of the system and shortens the data processing time of the system.

[0087] The matching unit 12 is used to generate a short-term predicted speed of the smallest road un...

Abstract

The embodiment of the invention, which relates to the data processing technology field, discloses a method and a system for rapid updating of traffic data. According to the invention, instantaneity and accuracy of road condition information received by a user terminal can be improved; and a reference value of the road condition information for the user can be enhanced. The method comprises the following steps that: real-time traffic data are filtered to obtain effective traffic data, wherein the effective traffic data at least include a vehicle coordinate, current time, a vehicle speed and a driving direction; according to a real-time average speed and a historical average speed of minimum road units of a driving target road, a short-period predicted speed of the minimum road units of the driving target road is generated; and the minimum road units are merged into a merged road, wherein the minimum road units are mutually connected and the short-period predicted speeds of the minimum road units belong to a same speed range; and traffic data of the merged road are issued to a user terminal in preset time. The method and the system provided in the invention can be applied for traffic data processing.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and system for quickly updating traffic data. Background technique [0002] With the continuous improvement of people's living standards, vehicles have increasingly become an indispensable part of people's lives, but at the same time, the problem of traffic congestion in many cities is also becoming more and more serious. Many car owners have purchased car navigation devices for the convenience of driving. The car navigation device is a driving auxiliary device that can help users accurately locate the current location, calculate the itinerary according to the predetermined destination, and guide the user to avoid congested roads and travel to the destination through map display and voice prompts for road condition information. [0003] The inventor found in the process of realizing the present invention that the current car navigation device has greatly reduced the real-...
