Traffic information communication system

Abstract

The invention relates to a traffic information communication system, which comprises a data collecting module which is used to obtain road traffic information of each road section and a data processing module which is used to store a database of the road traffic information of each road section, wherein each road section is respectively marked, the road traffic information can be processed into a data packet which accords with a transmission protocol, the road traffic information of each road section can be corresponding to a label of the road section in the data packet, the traffic information communication system also comprises a data sending unit which is used to modulate the data packet into a simulation radiofrequency signal to transmit and an information obtaining terminal which comprises a data receiving unit which is used to receive the data packet and a storage unit which is used to store an electronic map, wherein each road section in the electronic map is respectively marked with the label, the label is same with the label which represents same road section in the database of the data processing module, the information obtaining terminal also comprises a processing unit which is used to decode the data packet which is received by the data receiving unit and to reflect the road traffic information on a corresponding road section of the electronic map, and an information output unit which is used to output the electronic map which reflects the road traffic information.

Description

【Technical field】 [0001] The invention relates to a system for providing road traffic information to users. 【Background technique】 [0002] There are three ways to provide traffic information at present: release through radio stations and television stations, release through the Internet, and release through electronic screens set up on the roadside. [0003] The above three methods each have their advantages and disadvantages. The amount of information released by means of radio stations and television stations is limited, and the range of road sections covered by road traffic information is also very limited. In addition, users cannot obtain all the traffic conditions that they need to know about the route in time. [0004] The way of publishing traffic information through the website makes up for the shortcomings of radio and television. The data it provides is relatively comprehensive and basically covers all roads in the city. But the user must have a PC that can be c...

So this method is also inconvenient

[0005] The way of setting signs on the side of the road can inform users of the road conditions ahead in time, but the cost of setting up such signs is high, and the amount of information is small, and users cannot check them at any time
