Example 2:

An embodiment of the present invention provides a method for selecting a location of information triggering. As shown in FIG. 2, the method includes the following steps:

201. According to a preset selection rule, select an estimated information trigger location.

202. Acquire, according to the estimated information triggering position between the triggering position and the graphic representative position, the historical time recording value of the distance triggered by the estimated information, and obtain the estimated information triggering position to the graphic representative position. Reference speed.

The estimated information triggering location is described relative to a graphical representative location, the graphical representation location being the first divergent intersection depicted by the graphical real-time traffic information. The distance between the representation position of the graphic and the trigger position of the estimated information is the estimated information triggering distance. The driving speed of the vehicle is different on different roads (for example, the speed of the vehicle on the highway is faster than that on the ordinary road), so the estimated information triggering distance is also different. The estimated information triggering distance can be set according to a selection rule that presets different distance values for different roads. The estimated information trigger position is selected based on the trigger distance set by the estimated information.

Wherein the historical time record value comprises an arithmetic mean of at least two historical time records. The historical time record value may be obtained based on historical traffic information data, wherein the historical time record value is to acquire at least two historical time records, and the arithmetic mean value of the historical time record is calculated as a historical time record value, so that the historical time record value can be made.

The following is an example of the selection method of the trigger position of the above actual information: First, the trigger position of the estimated information is selected according to the trigger distance of the estimated information of the highway road and the expressway 1000m and the general road 800m. There is at least one traffic information issuance section between the estimated information triggering position and the graphic representative position (the traffic information issuance section is the shortest section of the traffic information release), as shown in FIG. 4, assuming a total of four release sections R1, R2 R3, R4, the lengths thereof are represented as DR1, DR2, DR3, and DR4, and the travel time of the vehicle on each of the released sections is represented as t(Rl), t(R2), t(R3), and t(R4).

Then, select historical data for the last week of the special event (such as National Day holiday) that does not affect traffic conditions, from 7:00 to 20:00 every day. Set to one time zone every 5 minutes, there are 12 time zones in 1 hour, and there are 12* 13 = 156 time zones every day from 7:00 to 20:00, so the data volume is obtained from 7:00 to 20:00 every week. =7* 156= 1092. The travel time of the vehicle at each time of the release section is recorded as t(R) l, t(R)2, t(R)3... t(R)n, if the travel time of the vehicle is in the time zone of the release section R 1 Is t(Rl) l, t(Rl)2, t(Rl)3... t(Rl)n. The historical time i of each time zone from R1 to R4 has been recorded as tl, t2, t3... tn, B'J: Tl = t(Rl ) l + t(R2) l + t(R3) l + t(R4) l

T2 = t(Rl )2 + t(R2)2 + t(R3)2 + t(R4)2

Therefore, the historical time record value T 3⁄4 ^tl

T = ——

When the user drives the vehicle on the road, the terminal will determine the current location of the vehicle and the direction of travel. When the vehicle reaches the actual information triggering position, the terminal determines whether the driving direction of the vehicle points to the graphic representative position corresponding to the actual information triggering position. When pointing to the graphic representative position corresponding to the actual information triggering position, the terminal requests the server to send the graphic. Real-time traffic information; If the driving direction of the vehicle does not point to the graphical representative position corresponding to the actual information triggering position, the terminal will not send a request to the server. If the server receives the request, the server sends the graphical real-time traffic information corresponding to the actual information trigger location to the terminal; then, the terminal will receive and display the graphical real-time traffic information. The user can determine the driving path based on the displayed graphical real-time traffic information. The terminal can determine whether the vehicle has left the graphical representative position, and if the vehicle has left the graphical representative position, the graphical real-time traffic information is turned off, and if the vehicle has not left the graphical representative position, the graphical real-time traffic information continues to be displayed.

An embodiment of the present invention provides a method for selecting an information trigger position, and using the set estimated information trigger distance divided by the historical time record value of the vehicle driving the trigger distance of the estimated information to obtain a trigger position of the vehicle from the estimated information. To the graph represents the reference speed of the position, thereby multiplying the reference speed by the preset reference time to obtain a suitable actual The information triggers the distance, and then determines the appropriate actual information trigger position, so that the terminal can display the graphical real-time traffic information at an appropriate time, and improve the quality of the terminal graphical real-time traffic information display function.
