Embodiment 1

[0062] In order to enable those skilled in the art to better understand the implementation process of the present invention, the implementation mode will be further described in detail below by taking the urban road network of Qingdao as an example.

[0063] figure 1 It is a flow chart of the specific implementation process of the present invention, and our implementation process is according to figure 1 process is carried out.

[0064] Step 101, using predefined traffic-related keywords such as "Qingdao Traffic" and "Qingdao Shandong Road" to capture in real time microblogs related to traffic information topics in urban areas of Qingdao and their related attributes on the Sina Weibo platform through the microblog data collection program Value, including the relevant information of the publisher, the text of the Weibo, the number of likes, the number of comments, the number of retweets, etc., for a newly collected Weibo.

[0065] The captured original information of Weibo is...

Abstract

The invention provides a traffic parallel method with mapping between microblog public sentiments and city road conditions. The method comprises steps of timely collecting and acquiring microblog message data related to specific city traffic information, and conducting four sub-steps for each acquired microblog message: (a) indicating original attributes of the microblog and mapping attributes in a formal way, (b) setting type attributes according to traffic topic classification data clusters, (c) extracting geographical position information according to city road data clusters and extracting specific topics feedback in the microblog according to traffic feedback information, and (d) calculating related index of each microblog according to the extracted basic attribute information. The index comprises credibility, affection degree and importance. Traffic information of the microblogs can be quickly classified and positioned; visualized display and precautions can be achieved for traffic accidents, traffic jams and feedback information based on internet information; and assistant decision-making performance is provided for city traffic management, planning, emergency plan and problem solutions.

Description

technical field [0001] The invention relates to the technical field of Internet data processing, and in particular relates to a traffic parallel method for mapping microblog public opinion and urban road conditions. Background technique [0002] At present, the main traffic data collection technologies include fixed sensor collection, floating vehicle collection and mobile perception collection. Fixed sensor technology uses sensor nodes installed on the road or paved in the road to form a sensor network to collect traffic data at fixed points, but generally there is dependence on the installation site and environment, and it faces huge initial investment, short life cycle, and high maintenance costs. question. Floating car technology mainly uses floating cars (taxis, bicycles, etc.) traveling in the road network to collect GPS estimation data when they are driving and upload them to the server. However, there are also problems such as large investment, lack of data of othe...
