Problems solved by technology

This method not only consumes a lot of manpower, but also is inefficient, the real-time performance cannot be effectively guaranteed, the accuracy rate and omission rate are easily limited by individuals, the information platform is also poorly shared, and the availability of information resources cannot be fully utilized. It can be said that the acquisition of road condition information data sources reflected in these problems is a shortcoming in the entire industrial chain.

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] First please refer to figure 1 , figure 1 It is a flow chart of the method for generating real-time road condition information according to the present invention, which generally embodies the main implementation steps of the present invention, including:

[0030] Step S110, listening to traffic information broadcast by radio stations within a wide area and converting it into audio signals.

[0031] Specifically, the air interface wireless signal can be received by a signal receiving device such as a radio wave receiving device, and the wireless signal can be converted into an audio signal and output to the next link.

[0032] It should be emphasized that in this embodiment, the traffic information that is automatically listened to comes from ordinary radio broadcasts. Based on the characteristics of ordinary radio broadcasts, it shows complexity and ...

Abstract

The invention discloses a real-time traffic condition information generating method which comprises the steps of: automatically receiving broadcast; performing speed recognition on a broadcast signal, performing keyword detection, extracting traffic condition information from the broadcast signal, and converting the traffic condition information to text information; converting the text information to a map feature language through natural language processing technique, drawing and feeding back in a map product for forming traffic condition information. Correspondingly, the invention further provides a real-time traffic condition generating system. The real-time traffic condition information generating method can provide real-time traffic condition information for users in a wide area. Based on the real-time traffic condition information, a series of applications of navigation, going-out planning, etc. can be performed. Furthermore a large amount of labor can be saved for a traffic condition product provider.

Description

technical field [0001] The invention relates to the field of providing real-time road condition information for traffic, in particular to a method for generating real-time road condition information. Background technique [0002] With the increasing of human travel activities, the demand for real-time traffic conditions is becoming more and more important. For example, drivers driving on urban roads need to keep abreast of the road congestion in front of them in order to avoid them; people on the public transport system need to inquire about road conditions for route planning before traveling; traffic information providers on the Internet, It is necessary to master real-time traffic information in order to complete effective services for customer inquiries and so on. With the rapid development of science and technology, modern technology products such as mobile handheld terminals and vehicle navigation equipment have entered thousands of households, and the means of releasi...
