the number of the traffic lights of the navigation route 2 is 6, and the kilometers are 18 kilometers;
the number of the traffic lights of the navigation route 3 is 5, and the kilometer number is 20 kilometers;
the number of the traffic lights of the navigation route 4 is 4, and the kilometer number is 19 kilometers;
therefore, the navigation route with the least traffic lights is the navigation route 4, and the kilometer number of the navigation route 4 is 19 kilometers;
the total kilometers of the navigation routes 1, 2, 3, 4 are 73 kilometers, and according to the total kilometers of the navigation routes 1, 2, 3, 4 and the number 4 of the navigation routes, the average kilometer of the navigation routes is generated as follows: (16 +18+20+ 19)/4 = 18.25;

In the embodiment of the invention, if the ratio is in the preset ratio range, the navigation route with the minimum traffic light quantity is sent to the navigation terminal, namely, the server sends the navigation route with the minimum traffic light quantity to the navigation terminal under the condition that the navigation routes are close to each other. Therefore, the embodiment of the invention considers the number of the traffic lights in the navigation route, and is beneficial to finding out a proper navigation route. Therefore, traffic lights of the vehicle paths are reduced, and the driving distance of the vehicle is reduced.
It should be noted that: there are two implementations of S108, detailed as follows:
the first implementation mode comprises the following steps: judging whether the ratio is in a preset ratio range, if so, judging whether a plurality of navigation routes with the minimum number of traffic lights exist, if so, sending the navigation routes with the minimum number of traffic lights to the navigation terminal, and if so, sequencing the kilometers of the navigation routes with the minimum number of traffic lights to obtain the navigation routes with the minimum kilometers and the minimum number of traffic lights, and sending the navigation routes with the minimum kilometers and the minimum number of traffic lights to the navigation terminal.
The navigation routes with the least traffic lights are as follows: and more than two navigation routes with the least traffic lights.
For convenience of description, the number of the navigation routes is 5, for example, as follows:
the number of the traffic lights of the navigation route 5 is 4, the kilometer number is 18 kilometers, the kilometer number 18 of the navigation route 5 is compared with the average kilometer number 18.25 of the navigation route, 18/18.25=0.98, so that the ratio of the kilometer number of the navigation route 5 to the average kilometer number of the navigation route is 0.98, the preset ratio range is 0.5-1.3, and the ratio of the kilometer number of the navigation route 5 to the average kilometer number of the navigation route is within the preset ratio range. In this case, the navigation route 4 and the navigation route 5 are both the navigation route with the least number of traffic lights, that is, there are two navigation routes with the least number of traffic lights, and the ratios of the average kilometers of the navigation routes 4 and 5 to the average kilometers of the navigation routes are all within the preset ratio range, the kilometers of the navigation routes 4 and 5 are sorted, the kilometer of the navigation route 4 is 19 kilometers, the kilometer of the navigation route 5 is 18 kilometers, obviously, the kilometer of the navigation route 5 is the least, therefore, the navigation route 5 is the navigation route with the least kilometers and the least number of traffic lights, and the server sends the navigation route 5 to the navigation terminal.
The beneficial effects are as follows: under the condition of close distance, the server sends the navigation route with the least kilometers and the least traffic lights to the navigation terminal, so that the traffic lights of the vehicle route where the navigation terminal is located can be further reduced, and the driving distance of the vehicle is reduced.
The second implementation mode comprises the following steps: judging whether the ratio is in a preset ratio range, if so, judging whether a plurality of navigation routes with the minimum number of traffic lights exist, if so, sending the navigation routes with the minimum number of traffic lights to the navigation terminal, and if so, sequencing the ratio of the navigation routes with the minimum number of traffic lights to the average kilometer number of the navigation routes, acquiring the navigation routes with the minimum ratio and the minimum number of traffic lights, and sending the navigation routes with the minimum number of kilometers and the minimum number of traffic lights to the navigation terminal.
For convenience of description, the number of the navigation routes is 5, for example, as follows:
the number of the traffic lights of the navigation route 5 is 4, the kilometer number is 18 kilometers, the kilometer number 18 of the navigation route 5 is compared with the average kilometer number 18.25 of the navigation route, 18/18.25=0.98, so that the ratio of the kilometer number of the navigation route 5 to the average kilometer number of the navigation route is 0.98, the preset ratio range is 0.5-1.3, and the ratio of the kilometer number of the navigation route 5 to the average kilometer number of the navigation route is within the preset ratio range. In this case, the navigation route 4 and the navigation route 5 are both the navigation route with the smallest number of traffic lights, that is, there are two navigation routes with the smallest number of traffic lights, and the ratios of the navigation route 4, the navigation route 5 and the average kilometer number of the navigation route are all within the preset ratio range, and the ratios of the navigation route 4, the navigation route 5 and the average kilometer number of the navigation route are sorted, that is, sorted by 1.04 and 0.98, it is obvious that the ratio of the navigation route 5 and the average kilometer number of the navigation route is the smallest, so that the navigation route 5 is the navigation route with the smallest ratio and the smallest number of traffic lights, and the server sends the navigation route 5 to the navigation terminal.
The beneficial effects are as follows: under the condition of close distance, the server sends the navigation route with the minimum ratio and the minimum number of traffic lights to the navigation terminal, so that the traffic lights of the vehicle route where the navigation terminal is located can be further reduced, and the driving distance of the vehicle is reduced.
