The principle of the green wave speed is that the position and the running direction of a vehicle in a road network are judged through longitude and latitude coordinates of the vehicle and map data, then whether a signal lamp exists at an intersection in front of the vehicle is judged, if yes, the real-time state of the signal lamp is extracted and directly displayed to a driver, and finally the highest running speed and the lowest running speed required by the vehicle to pass through the intersection without stopping during the green light period of the time or the next time are calculated according to the position of the vehicle and the state of the signal lamp and are prompted. The difficulty of the service is how to quickly judge whether signal lamps exist at the intersection in front of the vehicle, so that intersection information and traffic light information need to be matched.
However, how to quickly determine whether there is a signal light at the intersection ahead of the vehicle, and how to acquire the time information of the signal light is the key to calculate the green wave speed when there is a signal light at the intersection ahead.

And finally, importing the form data into a navigation system by the operation and maintenance personnel. Meanwhile, operation and maintenance personnel also need to repeatedly verify the form data and determine that the signal lamps corresponding to the links in the road data are accurate. Thus, the process of road link, intersection and signal lamp matching is time consuming and labor consuming.
In view of this, an embodiment of the present invention provides a method for associating signal lamp time information, where the method includes: determining a target continuous road chain of the intersection and a target passing direction of the target continuous road chain; the target traffic direction points to the intersection; acquiring a target position of a target connection road link relative to a road junction; according to the target position, determining target time information corresponding to the target position from the mapping relation of the target signal lamp; the mapping relation comprises a plurality of directions and time information corresponding to each direction, and the distance between a target signal lamp and the intersection is smaller than a first threshold value; and associating the target connection link and the target traffic direction with the target time information to obtain an association result of the time information.

Then, the electronic equipment acquires the position of the continuous road chain relative to the intersection, and takes the distance between the signal lamp and the intersection smaller than a first threshold value as the signal lamp corresponding to the continuous road chain. Because the mapping relation of the signal lamp comprises a plurality of directions and the time information corresponding to each direction, the electronic equipment determines the time information corresponding to the directions according to the directions and the mapping relation of the connection link chain. And finally, the electronic equipment associates the continuous link and the passing direction of the continuous link with the time information to obtain an association result of the time information.

Fig. 2 is a method for associating signal lamp time information according to an embodiment of the present invention, where the method includes the following steps S201 to S204.
S201, the electronic equipment determines a target connection road chain of the intersection and a target passing direction of the target connection road chain.
Wherein the target traffic direction points to the intersection.
In one design, in order to determine a road link where a vehicle enters the intersection from a plurality of continuous road links corresponding to the intersection, as shown in fig. 3, S201 provided by the present invention specifically includes the following S2011-S2014.
S2011, the electronic device obtains the link at the intersection and the passing direction of each link.
As a possible implementation manner, the electronic device obtains all the link chains corresponding to each intersection and the passing direction of each link chain from the storage module.
Illustratively, in the case where the intersection is a complex intersection, the complex intersection N1 shown in (a) in fig. 4 includes four nodes, N1 point, N2 point, N3 point, and N4 point. Wherein, point n1 is the master node, and points n2, n 3, and n 4 are the subnodes. Each node corresponds to 2 links. The electronic equipment acquires 8 continuous road chains corresponding to the complex intersection and the passing direction of each continuous road chain. In the case where the intersection is a single-node intersection, the single-node intersection N2 shown in fig. 4 (b) includes one node N5, and the node N5 corresponds to 4 links. The electronic equipment acquires 4 continuous road chains corresponding to the single-node intersection and the passing direction of each continuous road chain.
It should be noted that the direction corresponding to the connection link chain may be forward direction passing, reverse direction passing, bidirectional passing, and no passing. When the continuous link chain can pass from the starting node to the ending node, the continuous link chain is called to pass in the positive direction; when the continuous link chain can pass from the termination node to the starting node, the reverse direction passing is called; when the continuous road chain can pass in the positive direction and the reverse direction, the bidirectional passing is called; when the continuous link chain can not pass in the positive direction and the reverse direction, the continuous link chain is called as no-pass.
S2012, the electronic device obtains at least one passing direction of a continuous road chain of the intersection.
As a possible implementation manner, the electronic device selects one link from the multiple links, and determines at least one passing direction corresponding to the link.
For example, as shown in fig. 4 (b), the electronic device acquires the traffic direction of the link chain L9 at the complex intersection N2. Since the traffic direction of the link chain L9 is bidirectional, the electronic device acquires two traffic directions of the link chain L9: forward direction traffic and reverse direction traffic.
S2013, the electronic equipment judges whether the first passing direction of the continuous road chain points to the intersection or not.
The first passing direction is any one of at least one passing direction.
Specifically, the electronic device obtains a start node position, an end node position, a traffic direction and an intersection node position of the continuous link. The electronic equipment judges whether the distance between the passing end point of the continuous road chain and the node of the intersection is less than a preset threshold value.
For example, as shown in (b) in fig. 4, the electronic device determines whether the distance between the passing node of the continuous link chain L9 in the passing direction 1 and the node of the intersection is smaller than a preset threshold.
S2014, if the first passing direction of the connected road link points to the intersection, the electronic device determines that the connected road link is the target connected road link of the intersection and the first passing direction is the target passing direction of the intersection.
Specifically, the electronic device determines that the continuous road link is a target continuous road link of the intersection and the first passing direction is a target passing direction of the intersection if the distance between the passing end position of the continuous road link and the node of the intersection is smaller than a preset threshold.
For example, as shown in (b) in fig. 4, when the electronic device determines that the distance between the passing node of the link chain L9 in the passing direction 1 and the node N5 of the intersection is smaller than the preset threshold, it is determined that the link chain L9 is the target link chain of the intersection N2, and the passing direction 1 is the target passing direction of the intersection.
It will be appreciated that through the above steps, the electronic device is able to determine all links of the intersection that the vehicle has driven into the intersection in the first direction of travel.
S202, the electronic equipment acquires the target position of the target connecting road link relative to the intersection.
In one design, in order to determine the target position of the continuous road link relative to the intersection, as shown in fig. 5, S202 provided by the present invention specifically includes following S2021-S2022.
S2021, the electronic equipment determines an azimuth angle of the midpoint of the target continuous road chain pointing to the intersection.
As a possible implementation manner, the electronic device obtains the midpoint position of the target continuous link from the storage module, and obtains an azimuth angle for determining that the midpoint of the target continuous link points to the intersection node according to the midpoint position of the continuous link and the intersection node position.
Illustratively, as shown in fig. 6, the electronic device connects the midpoint M1 of the link chain and the node M2 of the intersection in parallel. The electronic equipment determines that the azimuth angle beta of the middle point of the target continuous road chain pointing to the intersection is 25 degrees.
S2022, the electronic equipment determines the target direction of the target connection road link relative to the intersection according to the azimuth.
Illustratively, as shown in fig. 6, the electronic device determines that the target direction of the target link is north relative to the intersection according to the azimuth angle β. The standard for dividing the azimuth of the continuous road chain according to the azimuth is as follows: north at 316-45 degrees; east at 46-135 deg.; 136-225 ℃ is south; 226-315 degrees is west. It should be noted that, other division standards may exist according to the azimuth of the continuous link chain divided by the azimuth, and the present invention is not limited specifically.
As another possible implementation manner, the electronic device obtains the start node position of the target continuous road chain from the storage module, and obtains an azimuth angle for determining that the start node of the target continuous road chain points to the intersection according to the start node position of the continuous road chain and the intersection node position.
It can be understood that there are various implementation manners for the electronic device to determine the azimuth angle at which the target continuous road link points to the intersection, and the present invention is not limited in particular.
S203, the electronic equipment determines target time information corresponding to the target direction from the mapping relation of the target signal lamp according to the target direction.
Wherein the signal lamp is a traffic light.
The mapping relation comprises a plurality of directions and time information corresponding to each direction, and the distance between the target signal lamp and the intersection is smaller than a first threshold value.
As a possible implementation manner, the electronic device obtains, from the storage unit, the target signal lamp data including a plurality of orientations and a time information mapping relationship corresponding to each orientation. And the electronic equipment determines target time information corresponding to the target direction from the mapping relation of the target signal lamp according to the target direction.
Specifically, the electronic device first obtains the signal lamp static data from the storage module. The electronic equipment selects the traffic light with the distance to the intersection smaller than the first threshold value according to the position of the red street light and the position of the node in the static data of the signal light, and determines that the traffic light is the target traffic light. Then, the electronic equipment acquires the signal lamp dynamic data from the storage module. And the electronic equipment determines target time information corresponding to the target direction from a plurality of directions in the signal lamp dynamic data and the time information mapping relation corresponding to each direction according to the target direction.
For example, the first threshold may be 10m, and the first threshold is not particularly limited in the present invention.
Illustratively, as shown in fig. 7, the distance between the signal lamp 30 and the node 31 of the intersection is less than 10m, and the electronic device determines that the signal lamp corresponding to the intersection 31 is the signal lamp 30. The electronic device determines time information corresponding to the position of the road link L32 according to the position angle of the continuous road link L32 and the mapping relation of the signal lamp 30. Wherein, the mapping relation is shown in the following table 1:
TABLE 1
| Orientation | Time information |
| North China | Time of signal lamp |
| South China | Time of signal lamp |
| East | Time of signal lamp |
| Western medicine | Time of signal lamp |
S204, the electronic equipment associates the target connection link and the target traffic direction with the target time information to obtain an association result of the time information.
As a possible implementation manner, the electronic device associates the target link chain, the target traffic direction, and the target time information into one piece of data, obtains an association result of the time information, and stores the association result in the storage module.
It can be understood that, through this step, the present invention can associate the continuous links of each real road and the traffic direction corresponding to each continuous link with the signal light time information, and store the association result in the form of a table in the electronic device. Thereby providing more travel services for the vehicle. The correlation result can be referred to table 2.
TABLE 2
| Connecting road chain | Direction of passage | Time information |
| Connecting link 120 | Passing in positive direction | Time of signal lamp |
| Connection link 121 | Passing in the reverse direction | Time of signal lamp |
According to the technical scheme provided by the invention, the electronic equipment firstly determines the continuous road chain of which the traffic direction points to the intersection. Then, the electronic equipment acquires the position of the continuous road chain relative to the intersection, and takes the distance between the signal lamp and the intersection smaller than a first threshold value as the signal lamp corresponding to the continuous road chain. Because the mapping relation of the signal lamp comprises a plurality of directions and the time information corresponding to each direction, the electronic equipment determines the time information corresponding to the directions according to the directions and the mapping relation of the connection link chain. And finally, the electronic equipment associates the continuous link and the passing direction of the continuous link with the time information to obtain an association result of the time information. Therefore, the electronic equipment associates the continuous road link and the passing direction of the continuous road link with the time information, and therefore human resources are saved.
In one design, in order to calculate the green wave speed of the vehicle traveling on the current link, as shown in fig. 8, the present invention provides a method for associating traffic light time information, which includes the following steps S205 to S207.
S205, the electronic equipment acquires the current connecting link chain where the vehicle is located and the current passing direction.
As a possible implementation manner, the electronic device obtains the current connection link where the vehicle is located according to the current position of the vehicle. The electronic equipment acquires the current passing direction of the vehicle according to the positions of the vehicle at different moments.
S206, the electronic equipment determines current time information corresponding to the current continuous link and the current traffic direction from the association result according to the current continuous link and the current traffic direction.
And S207, the electronic equipment determines the green wave speed of the vehicle according to the current time information.
As a possible implementation manner, the electronic device calculates the green wave speed of the vehicle according to the current position of the vehicle, the position of the intersection corresponding to the current continuous road link, and the current time information.
Specifically, the electronic device obtains the distance from the vehicle to the signal lamp according to the current position of the vehicle and the position of the intersection corresponding to the current continuous road link. Further, the electronic device obtains the green wave speed of the vehicle according to the distance and the current time information.
