Abstract

The embodiment of the invention provides a navigation electronic map-based method and a navigation electronic map-based device for generating a TMC matching table, which relate to the field of traffic information service and can automatically generate the TMC matching table. The invention adopts the following solution that the method comprises the following steps: inputting an electronic map file and a TMC position table file; automatically matching each link with each position point according to the input electronic map file and TMC position table file; and performing attribute assignment for each link according to a matching relationship so as to acquire the TMC matching table. The embodiment of the invention is used for generating the TMC matching table.

Description

technical field [0001] The invention relates to the field of traffic information services, in particular to a method and device for generating a TMC matching table based on a navigation electronic map. Background technique [0002] TMC (Traffic Message Channel) is the abbreviation of real-time traffic information. It can broadcast real-time traffic and weather information through FM wireless frequency modulation system or mobile wireless network. The data information is provided by the vehicle wireless receiving terminal or navigation equipment equipped with TMC standard. Receive and decode, and provide to the driver to provide effective assistance for driving. [0003] When providing TMC traffic information, it is necessary to complete the production of TMC location table and matching table. Among them, the TMC location table is defined and described according to the international TMC standard and can be used as traffic information in an area (generally a city) to publish ...
