And the server takes the inducer information corresponding to the time navigation sections as the inducer information corresponding to the target navigation sections.

In the following, taking the starting point location information as beijing and the end point location information as pizza as an example, a process of obtaining a segmented data structure by segmenting the target guidance information by time is described:

If the plurality of target navigation segments are the distance navigation segments, because the distance between the road section position information corresponding to each distance navigation segment and the starting point position information is different, each distance navigation segment can be sequenced in sequence according to the corresponding distance, and the target navigation sequence is obtained.

If the plurality of target navigation segments are the time navigation segments, and the client correspondingly drives the corresponding road segments in each time navigation segment, each time navigation segment can be sequentially sequenced according to the distance between the position information of the road segments driven by the client and the position information of the starting point in each time navigation segment, so that the target navigation sequence is obtained.

If the target navigation segments are the segments corresponding to the road name information, the segments corresponding to the road name information may be sequentially ordered according to the distance between the position information of the segment corresponding to the road name information and the start position information, so as to obtain the target navigation sequence.

If the target navigation segments are the traffic sign segments, the target navigation sequence may be obtained by sequentially sorting the traffic sign segments according to the distance between the segment position information corresponding to each of the traffic sign segments and the start point position information.

And S1013, the server takes the most-front ordered target navigation segment in the target navigation segment sequence as a current target navigation segment, and takes the inducer information corresponding to the current target navigation segment as the current inducer information.

The current inducer information is equivalent to the inducer information corresponding to the first target navigation segment, that is, the server issues complete route information and a part of inducer information to the client, and the client initializes the induction engine after receiving the complete route information and the part of inducer information, enters a navigation mode, and drives on the current target navigation segment according to the received part of inducer information.

If the target elicitor information is segmented according to the fixed distance and the preset unit distance is 10 kilometers, the server issues the complete route information (namely the target route information) and the elicitor information corresponding to the first distance navigation section (within 10 kilometers of the current position downstream of the client, namely 0-10 kilometers).

If the target elicitor information is segmented according to time and the preset unit time is 0.5h, the server issues the complete route information (namely the target route information) and the elicitor information corresponding to the first time distance period (0-0.5 h).

If the target elicitor information is segmented according to the road name information, the server issues the complete route information (i.e., the target route information) and the elicitor information of the road section corresponding to the first road name information where the target route information appears.

If the target elicitor information is segmented according to specific traffic lights, the server issues the complete route information (namely the target route information) and the elicitor information corresponding to the first traffic sign road section.
