The following two embodiments are respectively described with respect to two strategies for generating a seismic escape route.
In one embodiment of the present invention, generating a plurality of seismic escape routes corresponding to a plurality of travel modes according to a risk level of a target risk area includes:
for any type of travel mode:
determining an escape starting point of a user according to the signaling data;
determining an escape terminal point of a user based on the risk area and the risk level thereof;

if the risk level of the target risk area is medium risk or low risk, a Dijkstra algorithm is adopted to generate an earthquake escape route of the current type of travel mode according to the escape starting point, the escape ending point and the map data.
And determining the position of the user, namely the escape starting point of the user, based on the signaling data. The risk area where the escape terminal is located may have a risk level lower than the risk area where the escape starting point is located, and may also be a risk area having the same risk level as the escape starting point. The escape ending point can be positioned on a straight line where the central point of the earthquake and the escape starting point are positioned. The escape ending point is further from the center point in the earthquake than the escape starting point.
The target area is an area including an escape start point and an escape end point, and the range of the area can be determined according to different manners, for example, the target area is a rectangular area, and the escape start point and the escape end point are positioned on two parallel sides.
After the escape starting point and the escape ending point are determined, a Dijkstra algorithm can be adopted to carry out path planning by combining map data. The specific planning process is not described in detail herein.
In one embodiment of the present invention, generating a plurality of seismic escape routes corresponding to a plurality of travel modes according to a risk level of a target risk area includes:
for any type of travel mode:
determining an escape starting point of a user according to the signaling data;
determining an escape terminal point of a user based on the risk area and the risk level thereof;
acquiring map data of a target area according to an escape starting point and an escape ending point; wherein, the map data comprises a plurality of road nodes;
if the risk level of the target risk area is high risk, a Dijkstra algorithm is adopted to generate an earthquake escape route in a current type of travel mode according to the escape starting point, the escape ending point, the map data and population density of the area where the road nodes are located; the population density of the area where the road nodes are located is inversely proportional to the probability that the road nodes are located in the earthquake escape route.
Compared with the medium risk and low risk, the building and the like in the high risk area can be damaged more seriously, so that the number of escaping people is large, when the earthquake escape route is generated, not only the length of the route but also the population density of the area where the road node is located need to be considered, and under the condition that other conditions are the same, the larger the population density is, the smaller the probability that the road node is located in the earthquake escape route is. The range of the area where the road node is located can be preset, for example, the area is a circular area with the road node as the center and the preset distance as the radius, and the area can be adjusted based on actual requirements.
Generating a seismic escape route according to an escape starting point, an escape ending point, map data and population density of an area where road nodes are located, wherein the seismic escape route specifically comprises the following steps:
and marking the escape terminal point and the road node as undetermined, and adding the undetermined escape terminal point and the undetermined road node into a queue. Taking the escape starting point as a current node, determining the score of an undetermined node based on the distance from the current node and the population density of the area where the road node is located, taking out one undetermined node from the queue based on the size of the score, marking the undetermined node as determined, updating the newly marked determined node as the current node, continuously executing the steps of determining the score of the undetermined node based on the distance from the current node and the population density of the area where the road node is located, selecting one undetermined node based on the size of the score, marking the undetermined node as determined until the queue is empty or the current node is the escape terminal point.
In an actual application scenario, the map data may further include: geometric information of the building;

and pushing the updated earthquake escape route to the current user.
If the other users contain the same road nodes as the current user's earthquake escape route, the current user's earthquake escape route can be adjusted based on the other users ' actual escape route, so as to provide more accurate earthquake escape route for the users.
According to the signaling data of the user, the actual escape route of the user can be determined, and if the actual escape route deviates from the earthquake escape route, traffic barriers formed by building collapse and the like can exist on the earthquake escape route. For example, the seismic escape route includes road nodes 1-4, the actual escape route of user 1 includes road nodes 1, 2, 6, and 7, and from road node 3, user 1 deviates from the seismic escape route, thereby indicating that traffic obstructions may exist between road nodes 2 and 3. The earthquake escape route of the user 2 also comprises road nodes 2, 3 and 4, but in view of the possible traffic obstacle between the road nodes 2 and 3, the road node 3 can be removed from the earthquake escape route, and the earthquake escape route is re-planned based on the rest road nodes and the current position of the user 2, so as to obtain an updated earthquake escape route.
In one embodiment of the present invention, the method may further comprise:
determining an actual escape route of the current user according to the signaling data of the current user, and if the actual escape route of the current user is not matched with the earthquake escape route, executing to acquire the signaling data of the user in the earthquake early warning area.

determining a target trip mode of the user within a preset time period from the current moment according to the signaling data;

Step 212: according to the escape start point and the escape end point, map data of the target area is acquired, if the risk level of the target risk area is medium risk or low risk, step 213 is performed, and if the risk level of the target risk area is high risk, step 214 is performed.
Step 213: and generating an earthquake escape route of the current type of travel mode according to the escape starting point, the escape ending point and the map data by adopting a Dijkstra algorithm.
Step 214: and generating an earthquake escape route in the current travel mode according to the escape starting point, the escape ending point, the map data and population density of the area where the road nodes are located by adopting a Dijkstra algorithm.
