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 provides a method for generating real-time road condition information. The method includes: automatically listening to the broadcast; performing speech recognition on the broadcast signal, performing keyword detection, extracting road condition information from it, and converting it into text information; using natural language processing technology, which converts text information into map feature language, draws and feeds back in map products, and forms traffic condition information. Correspondingly, the present invention also provides a system for generating real-time road condition information. The present invention can provide real-time traffic information for users in a wide area, based on which a series of applications such as navigation and travel planning can be performed, and a lot of manpower can be saved for road condition product providers.

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...
