Problems solved by technology

[0007] (1) When the server provides real-time traffic information for the client, there are many data file reading and writing processes, so the release period of the road condition data is relatively long;
[0008] (2) Flexible interface cannot be realized, and it is not suitable for vehicle-mounted equipment with low processing performance
[0010] However, the inventor found that the following disadvantages still exist in the above improvement scheme, that is: there are many data file reading and writing processes inside the server, resulting in a long cycle of road condition data release

Embodiment 1

[0049] Such as figure 1 As shown, the method for publishing traffic information provided by the embodiment of the present invention includes:

[0050] 101. Receive a request from a client for obtaining traffic information.

[0051] The request sent by the client is accepted from the client, and the request includes the data type of the traffic information that the client wants to obtain.

[0052] The data types include: traffic flow information, traffic event information and other information.

[0053] 102. Parse the request.

[0054] Analyze according to the customer request sent by the client, and analyze the user information carried in the request.

[0055] 103. Obtain traffic information corresponding to the parsing result from a cache server.

[0056] According to the parsed user information, the corresponding traffic information in the cache server is searched, and the traffic information corresponding to the user information is acquired.

[0057] 104. Send the acqu...

Embodiment 2

[0061] The method for publishing traffic information provided in the embodiment of the present invention will be described in detail below with a specific embodiment.

[0062] In this embodiment, the method for classifying packets, such as figure 2 As shown, it specifically includes the following steps:

[0063] 201. Receive traffic information provided by a traffic information data source; wherein, the traffic information data source includes: a traffic flow data source, a traffic event data source, and other data sources.

[0064] The traffic flow data source includes current traffic flow information; the traffic event data source includes road condition control information and traffic accident information; the other data sources include whether there are vacant parking spaces in the parking lot, the number of empty parking spaces in the parking lot, and the like.

[0065] Regularly receive traffic information from traffic flow data sources, traffic event data sources and ...

Embodiment 3

[0092] Corresponding to the method for publishing traffic information in the first embodiment above, this embodiment of the present invention provides a system for publishing traffic information, such as image 3 As shown, the system includes:

Abstract

The embodiment of the invention discloses a method and system for releasing traffic information and relates to the communication technical field. The method and system can be used to reduce the release cycle of road information and increase the release efficiency. The method comprises the following steps: receiving a request of a client for obtaining traffic information; analyzing the request; obtaining traffic information corresponding to the analytic result from a cache server; and sending the obtained traffic information to the client. The method and system provided by the embodiment of the invention are suitable to be used to release real-time traffic information to the client.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and system for publishing traffic information. Background technique [0002] At present, the publishing system in the prior art adopts such as figure 1 The architecture method uses an FTP (File Transfer Protocol, file transfer protocol) server to release traffic data to the outside world. The basic flow of traffic data release is as follows: [0003] (1) The FCD (Floating Car Data, floating car data) processing system regularly generates standard format RTIC (Real-Time Information of China, China's real-time traffic information service standard) data files and TMC (Traffic Message Channel, traffic information channel) data document; [0004] (2) The FCD processing system copies the RTIC and / or TMC data files to the FTP server; [0005] (3) The application client using the real-time traffic data file downloads data to the FTP server through the FTP protocol. ...
