Abstract

The embodiment of the invention provides a road indexing method and a road indexing device applied to dynamic traffic information processing, and relates to the field of traffic information services. The method and the device have the advantages of automatically performing road indexing to generate a road index file, reducing manual operation and improving production efficiency and accuracy. The method comprises the following steps that: a navigation electronic map is input into a road index generation device; the road index generation device automatically performs segmentation processing on roads according to the navigation electronic map and a road index generation rule to obtain each segment on each road and matches a relevant parameter for each segment to generate the road index file; and the road index generation device outputs the road index file. The method and the device in the embodiment of the invention are used for the road indexing.

Description
