Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
The countdown display method of the embodiment of the invention is applied to the server. The passenger sends out the bill of lading request at client side reservation network about car, and the server side is responded for the first time after the bill of lading request, based on the preference characteristics such as current supply and demand state, current supply and demand characteristic and passenger's history wish, more rationally, more accurately carries out the countdown show.
The network taxi is a short name of network taxi reservation, and the network taxi can comprise a taxi, a windward vehicle, a express vehicle, a special vehicle and the like. The server side can be a server of each network vehicle travel platform. The client can be an APP (application program) for each network about travel.
Referring to fig. 1, a flowchart of steps of a countdown presentation method according to an embodiment of the present invention is shown.
As shown in fig. 1, the countdown display method may include the steps of:
step 101, detecting the current supply and demand state after the passenger bill of lading request sent by the client is responded for the first time.
The passenger performs corresponding operations on the client, such as setting a starting point position, an ending point position, a selected vehicle type and the like, and then clicks a call button to trigger a bill of lading request, and the client sends the passenger bill of lading request to the server.
After receiving the bill of lading request, the server waits for the driver to respond to the bill of lading request. After the bill of lading request is responded for the first time, the server detects the current supply and demand state. The supply and demand state may include a good supply and demand state, a bad supply and demand state, and the like.
And 102, judging whether to display countdown according to the supply and demand state.
And the server judges whether the countdown is displayed on the client according to the current supply and demand state. For example, when the supply and demand state is good, the countdown can be displayed selectively; when the supply and demand state is poor, the countdown can be optionally not displayed.
And step 103, after judging that the display countdown is performed, calculating the display countdown time length according to the current supply and demand characteristics and the preference characteristics such as the historical wish of the passengers.
After judging to display the countdown, the server can acquire the current supply and demand characteristics, the historical wish of the passengers and other preference characteristics, and calculate the countdown duration of the display according to the current supply and demand characteristics, the historical wish of the passengers and other preference characteristics. For example, in the case where the supply and demand are good and the passengers wish, the calculated countdown period is appropriately increased; in the case that a good supply and demand single passenger is unwilling or the like, the calculated countdown time length is appropriately reduced; in the case of poor supply and demand, countdown may not be exhibited, and so on. The calculated countdown time length is more reasonable and accurate, user experience can be improved, and capacity efficiency can be fully utilized.
Step 104, sending a countdown display instruction carrying the countdown duration to the client.
After judging to display the countdown and calculating the countdown duration of the display, the server sends a countdown display instruction to the client, wherein the countdown display instruction can carry information such as the countdown duration obtained by calculation.
After receiving the countdown display instruction, the client can pop up the countdown card, display the countdown according to the countdown time length carried in the countdown display instruction, and display a clear prompt document on the countdown card. FIG. 2 is a schematic diagram of a countdown display interface according to an embodiment of the present invention. As shown in fig. 2, a countdown card is displayed in the countdown display interface, the real-time countdown duration is displayed in the countdown card, and a prompt document of "match best vehicle for you" is displayed.
In the embodiment of the invention, after the passenger bill of lading request sent by the client is responded for the first time, the server can judge whether to display countdown based on the current supply and demand state, and calculate the countdown duration of display according to the current supply and demand characteristics and the historical wish of the passenger under the condition that the countdown is judged to be displayed. Because the current supply and demand factors and the factors of whether passengers are willing to wait or not are considered, the calculated countdown time length is more reasonable and more accurate.
Referring to fig. 3, a flowchart of steps of another countdown display method of an embodiment of the present invention is shown.
As shown in fig. 3, the countdown display method may include the steps of:
In step 301, after the passenger bill of lading request sent by the client is responded for the first time, the current supply and demand state is detected.
When a passenger takes a bill, a starting point position, an end point position, various selected vehicle types (such as vehicle types M1, M2 and M3 … …) and the like can be set. After the passenger bill of lading, the customer end sends the bill of lading request of this passenger to the service end. The bill of lading request may include information such as the passenger's user identification, start position, end position, selected vehicle type, etc.
After receiving the bill of lading request, the server waits for the driver to respond to the bill of lading request. After the bill of lading request is responded by a driver of a selected vehicle model Mj for the first time, the server detects the current supply and demand state.
In an alternative embodiment, the process of detecting the current supply and demand state may include the following steps A1 to A3:
And A1, acquiring the receipt quantity and the bill quantity in the latest preset duration in a preset area range taking the starting point position as the center.
In the implementation, a Hex code of a starting point position is obtained, a preset area range taking the starting point position as a center is obtained according to the Hex code, and a pick-up amount in the latest preset duration in the preset area range are obtained.
For specific values of the preset area range and the preset duration, any applicable value can be selected according to practical experience, and the embodiment of the invention is not limited to the specific value. For example, the preset area range centered on the start point position may be a regular hexagonal area range of 2.25 square kilometers, 2.5 square kilometers, 3 square kilometers, and the like centered on the start point position. For example, the preset duration may be 5 minutes, 8 minutes, 10 minutes, 12 minutes, and so on.
And A2, calculating the ratio of the receipt quantity to the bill of lading quantity as the current response rate.
Step A3, if the response rate is smaller than a first preset threshold value, determining that the current supply and demand state is poor supply and demand; otherwise, determining the current supply and demand state as good supply and demand.
For the specific value of the first preset threshold, any applicable value can be selected according to practical experience, which is not limited in the embodiment of the present invention. For example, the first preset threshold may be 30%, 40%, 50%, etc.
Step 302, determining whether to display countdown according to the supply and demand state. If yes, go to step 303; if not, step 307 is performed.
In the embodiment of the invention, if the current supply and demand state is poor supply and demand, no other drivers are likely to respond to the bill request within the countdown time period, so that in order to avoid time waste of passengers caused by no other drivers responding to the bill request, the countdown is not displayed when the current supply and demand state is poor supply and demand; if the current supply and demand state is good supply and demand, other drivers are likely to respond to the bill of lading request in the countdown time period, so that in order to be capable of matching the bill of lading request to the optimal vehicle type, the countdown is confirmed when the current supply and demand state is good supply and demand.
Step 303, after judging that the display countdown is performed, calculating the display countdown time length according to the current supply and demand characteristics and the preference characteristics such as the historical wish of the passengers.
If it is determined in step 302 that the countdown is displayed, a countdown duration of the display may be calculated according to the current supply and demand characteristics and the preference characteristics such as the historical wish of the passenger.
Wherein the current supply-demand characteristic is a current supply-demand characteristic of the starting point position, and the current supply-demand characteristic may include: and in a preset area range taking the starting point position as the center, the characteristics of receipt quantity, bill quantity, cancellation quantity, average waiting time length and the like in the latest preset time length are provided. For the preset area range and the latest preset time period, reference may be made to the description related to step 301 above.
The historical preferences of the passenger, etc. may include: the average waiting time of the passenger in the historical preset time, the waiting time of the passenger in at least one same historical time period corresponding to the current bill of lading time period and the like. For example, the history preset duration may be the last 20 days, 30 days, etc., and the same history period may be the same history period of 1 day, 2 days, 5 days, etc. before, which is not limited in the embodiment of the present invention.
In an alternative embodiment, a duration estimation model for estimating the countdown duration may be pre-trained. In the training process, a large amount of first sample data are acquired, and each first sample data comprises the current supply and demand characteristics of a sample corresponding to a sample bill, the historical wish preference and other preference characteristics of a sample passenger and the labeling information of the actual waiting time of the sample bill. Based on a large amount of first sample data, training a to-be-trained duration estimation model by adopting a machine learning algorithm, taking the current supply and demand characteristics of samples of a sample bill and the historical wish preference and other preference characteristics of the sample passenger as the input of the to-be-trained duration estimation model, and obtaining the sample estimated countdown duration of the sample bill output by the to-be-trained duration estimation model. Based on the labeling information of the sample pre-estimated countdown time length of the sample bill and the actual waiting time length of the sample bill, the loss value can be calculated. When the loss value meets the preset condition (such as the loss value is in the preset range, etc.), the training is determined to be completed, and the model after the training is used as a duration pre-estimated model.
Thus, the process of calculating the displayed countdown period based on the current supply and demand characteristics and the historical wish of the passenger may include: and taking the current supply and demand characteristics and the historical wish preference characteristics as inputs of a pre-trained duration estimation model, and taking the output of the duration estimation model as the countdown duration. The duration output by the duration prediction model represents the duration of the passenger (namely the duration of the passenger willing to wait), so that the output of the duration prediction model is used as the displayed countdown duration, and the current supply and demand characteristics and the passenger willing can be met. The time length estimation model is obtained based on a large number of sample training, and the countdown time length can be obtained more accurately and more quickly by using the time length estimation model.
In an alternative embodiment, because the duration estimation model has a certain uncertainty, the estimated countdown duration may deviate from the actual situation greatly, so the countdown duration can be further corrected. In the implementation, presetting reasonable minimum time length and maximum time length, and correcting the countdown time length to the minimum time length when the countdown time length is smaller than the preset minimum time length; when the countdown time length is longer than a preset maximum time length, correcting the countdown time length to the maximum time length, thereby ensuring that the countdown time length is within a reasonable range.
For the specific values of the minimum duration and the maximum duration, any applicable value can be selected according to practical experience, and the embodiment of the invention is not limited to the specific values. For example, the minimum duration may be 3 seconds, 5 seconds, etc., and the maximum duration may be 10 seconds, 15 seconds, etc.
Step 304, determining whether the countdown duration is calculated successfully. If yes, go to step 305; if not, go to step 306.
And 305, when the countdown time length calculation is successful, sending a countdown display instruction carrying the countdown time length to the client.
And when the countdown time length calculation is successful, the server side generates a countdown display instruction, wherein the countdown display instruction can carry the countdown time length obtained by calculation. And the server side sends the countdown display instruction carrying the countdown duration to the client side. After receiving the countdown display instruction, the client side responds to the countdown display instruction, pops up the countdown card, and starts the countdown according to the countdown time carried in the countdown display instruction.
And step 306, when the countdown duration calculation fails, sending a countdown display instruction carrying a preset default countdown duration to the client.
In the implementation, the countdown duration calculation may fail due to a failure of the duration estimation model or a failure of the server system. Therefore, in the embodiment of the invention, the default countdown duration can be preset. For example, the server may set a default countdown duration after receiving the passenger bill of lading request sent by the client; the server side can also set default countdown time length after the bill of lading request is responded for the first time; the server may also set a default countdown duration after the countdown duration fails to be calculated, which is not limited in the embodiment of the present invention. For a specific value of the default countdown duration, embodiments of the present invention are not limited, and for example, the default countdown duration may be set to the minimum duration mentioned in step 303, and so on.
When the counting down time length calculation fails, the server side generates a counting down display instruction, wherein the counting down display instruction can carry preset default counting down time length. And the server sends the countdown display instruction carrying the default countdown duration to the client. After receiving the countdown display instruction, the client side responds to the countdown display instruction, pops up the countdown card, and starts countdown according to the default countdown time carried in the countdown display instruction.
And 307, after judging that the countdown is not displayed, matching the bill of lading request with a target driver, and dispatching the target driver.
If it is determined in step 302 that the countdown is not displayed, the server matches the bill of lading request with the target driver, and dispatches the target driver.
In an alternative embodiment, the process of matching the bill of lading request with the target driver and dispatching the target driver may include: acquiring the number of drivers responding to the bill of lading request; taking the driver as a target driver under the condition that only one driver responds to the bill of lading request, and dispatching the target driver; under the condition that a plurality of drivers respond to the bill of lading request, respectively calculating the weight value of each driver, and based on the weight value of each driver, obtaining a target driver from the plurality of drivers by matching in a bipartite graph maximum weight matching mode, and dispatching the target driver.
Optionally, the process of calculating the weight value of any one driver for any one driver may include the following steps B1 to B2:
and step B1, acquiring the receiving driving time length, the receiving driving distance and the dispatch list forming rate of any driver.
The server side can obtain information such as the driving duration, the driving distance and the like of any one driver according to the current position of any one driver responding to the bill of lading request and the starting position of the bill of lading request.
In an alternative embodiment, a dispatch list rate prediction model for predicting the dispatch list rate of the driver may be trained in advance. In the training process, a large amount of second sample data are acquired, and each second sample data comprises sample historical order information of a driver corresponding to a sample bill, sample bill information and sample historical order information of a passenger, and labeling information of whether the sample bill is a bill. Based on a large amount of second sample data, training a to-be-trained form dispatching single rate estimation model by adopting a machine learning algorithm, taking sample historical order information of a driver, sample bill information and sample historical order information of passengers as input of the to-be-trained form dispatching single rate estimation model, and obtaining sample estimated form dispatching single rate of the sample bill output by the to-be-trained form dispatching single rate estimation model. Based on the sample pre-estimated dispatch rate of the sample bill of lading and the labeling information of whether the sample bill of lading is a bill, the loss value can be calculated. When the loss value meets the preset condition (such as that the loss value is in a preset range, etc.), the training is determined to be completed, and the model after the training is used as a single-rate prediction model.
Thus, the process of obtaining the dispatch list of any driver to form a single rate may include: acquiring historical order information of any driver, bill of lading information of the bill of lading request and historical order information of the passenger; and taking the history order information of any one driver, the bill of lading information of the bill of lading request and the history order information of the passenger as the input of a pre-trained bill-taking rate estimation model to obtain the bill-taking rate of any one driver output by the bill-taking rate estimation model. The dispatch single-rate estimation model is obtained based on a large number of sample training, and the dispatch single-rate of a driver can be obtained more accurately and more rapidly by using the dispatch single-rate estimation model.
The historical order information of the driver can comprise information such as historical receipt quantity, historical cancellation quantity, historical complaint rate and the like of the driver. The bill of lading information of the bill of lading request can include the information such as the charging duration, charging distance, prepaid price, supply and demand characteristics of the terminal position, etc. The historical order information for a passenger may include information for the passenger such as a historical pick-up amount, a historical cancellation amount, a historical pick-up amount, and the like.
And B2, carrying out weighted calculation on the driving receiving time length, the driving receiving distance and the dispatch list forming rate to obtain the weight value of any driver.
In implementation, the weight values corresponding to the receiving driving duration, the receiving driving distance and the dispatching single rate can be preset, and the weight value of any driver can be obtained by carrying out weighted calculation on the receiving driving duration, the receiving driving distance and the dispatching single rate according to the weight values corresponding to the receiving driving duration, the receiving driving distance and the dispatching single rate.
And forming a driver-to-passenger matrix by a plurality of drivers responding to the bill of lading request and passengers, and matching to obtain a target driver from the plurality of drivers by using a bipartite graph maximum weight matching mode based on the weight value of each driver responding to the bill of lading request, and dispatching the target driver. For the specific processing procedure of the bipartite graph maximum weight matching (KM algorithm), the correlation processing is performed according to actual experience, and the embodiment of the present invention will not be discussed in detail here.
In the embodiment of the present invention, after receiving the passenger bill request sent by the client, or after the bill request is responded for the first time, the server may set a flag=false (False indicates that the countdown is not displayed) indicating whether the countdown is displayed. When it is judged that the countdown is displayed, a flag=true (True represents the display countdown) of whether the countdown is displayed is set; and after judging that the countdown is not displayed, the sign of whether the countdown is displayed is not repeatedly set. And the server judges whether to send a countdown display instruction to the client or match a target driver for the client according to whether to display the countdown flag or not, and sends a bill.
