Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The countdown display method is applied to a server. The passenger appoints the network appointment to send out the bill-taking request at the client, and the server carries out countdown display more reasonably and more accurately based on the current supply and demand state, the current supply and demand characteristics, the historical wish of the passenger and other preference characteristics after the bill-taking request is responded for the first time.
The network taxi appointment method is characterized in that the network taxi appointment is short for a network taxi, and the network taxi appointment can comprise taxies, tailgating, express trains, special taxies and the like. The server side can be a server of each network car appointment travel platform. The client may be an APP (application) for each network appointment for travel.
Referring to fig. 1, a flowchart illustrating steps of a countdown displaying 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:
The passenger executes corresponding operations on the client, such as setting a starting position, a finishing position, selecting a vehicle type and the like, then clicks a 'calling' button, a bill lifting request can be triggered, and the client sends the passenger bill lifting request to the server.
And after receiving the bill raising request, the server waits for the driver to respond to the bill raising request. And when the bill drawing request is responded for the first time, the server detects the current supply and demand state. The supply and demand states may include good supply and demand, poor supply and demand, and the like.
And 102, judging whether to display countdown or not according to the supply and demand state.
And the server judges whether the countdown is displayed on the client side or not according to the current supply and demand state. For example, when the supply and demand status is good, the display countdown can be selected; when the supply and demand state is poor, the countdown is not displayed optionally.
And 103, after the display countdown is judged, calculating the displayed countdown duration according to the current supply and demand characteristics and the preference characteristics of the passengers such as the historical wishes and the like.
After the server judges the display countdown, the server can acquire the current supply and demand characteristics and the preference characteristics of the passengers such as historical wishes and calculate the displayed countdown duration according to the current supply and demand characteristics and the preference characteristics of the passengers such as the historical wishes. For example, when the demand and supply are good and the passenger wishes, the calculated countdown period is appropriately increased; under the conditions that the supply and demand are good, the single passenger does not want to wait, the calculated countdown time length is properly reduced; in the case of poor supply and demand, the countdown may not be displayed, and so on. The countdown time calculated according to the above is more reasonable and accurate, so that the user experience can be improved, and the transport capacity efficiency can be fully utilized.
And 104, sending a countdown display instruction carrying the countdown duration to the client.
And after judging the display countdown and calculating the displayed countdown time length, the server sends a countdown display instruction to the client, wherein the countdown display instruction can carry information such as the calculated countdown time length.
After the client receives the countdown display instruction, the countdown card can be popped up, countdown is displayed according to the countdown duration carried in the countdown display instruction, and a clear prompt document can be displayed 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 "match you for the best vehicle" is displayed.
In the embodiment of the invention, the server side can judge whether to display the countdown based on the current supply and demand state after a passenger bill-drawing request sent by the client side is responded for the first time, and under the condition of judging that the countdown is displayed, the countdown duration of the display is calculated according to the current supply and demand characteristics, the historical desire characteristics of the passenger and other preference characteristics. The counting down time length is more reasonable and accurate due to the consideration of the current supply and demand factors and the factors of whether passengers are willing to wait.
Referring to fig. 3, a flowchart illustrating steps of another countdown displaying method according to an embodiment of the present invention is shown.
As shown in fig. 3, the countdown display method may include the steps of:
When the passenger takes a bill, the passenger may set a starting position, a finishing position, a plurality of selected vehicle types (such as vehicle types M1, M2, M3 … …), and the like. And after the passenger bills of lading, the client sends the bill of lading request of the passenger to the server. The bill of lading request can include information such as the user identification of the passenger, the starting position, the ending position, the selected vehicle type and the like.
And after receiving the bill raising request, the server waits for the driver to respond to the bill raising request. When the bill of lading request is responded by a driver of a selected vehicle type 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 status may include the following steps a 1-A3:
and A1, acquiring the order receiving quantity and the order lifting quantity within the latest preset time within the preset area range with the starting point position as the center.
In the implementation, a Hex code of the 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 an order receiving amount and an order lifting amount within a latest preset time length in the preset area range are obtained.
For the specific values of the preset area range and the preset duration, any applicable value may be selected according to practical experience, which is not limited in the embodiment of the present invention. For example, the preset area range centered on the start position may be a regular hexagonal area range having an area of 2.25 square kilometers, 2.5 square kilometers, 3 square kilometers, or the like, centered on the start position. For example, the preset time period may be 5 minutes, 8 minutes, 10 minutes, 12 minutes, and the like.
And step A2, calculating the ratio of the order quantity to the order quantity as the current response rate.
Step A3, if the response rate is less than a first preset threshold, 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 may 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.
In the embodiment of the invention, if the current supply and demand state is supply and demand failure, no other driver is likely to respond to the bill raising request within the countdown time length, so that the countdown is determined not to be displayed when the current supply and demand state is supply and demand failure in order to avoid the time waste of passengers caused by no other driver responding to the bill raising request; if the current supply and demand state is good, other drivers are likely to respond to the bill of lading request within the countdown time length, so that in order to match the bill of lading request to the optimal vehicle type, the display countdown is determined when the current supply and demand state is good.
And 303, after the display countdown is judged, calculating the displayed countdown duration according to the current supply and demand characteristics and the preference characteristics of the passengers such as the historical wishes and the like.
If the display countdown is determined in step 302, the countdown duration of the display may be calculated according to the current supply and demand characteristics and the preference characteristics of the passenger, such as the historical desire.
The current supply and demand characteristics are current supply and demand characteristics of the starting point position, and the current supply and demand characteristics may include: and in a preset area range taking the starting point position as the center, the receiving amount, the lifting amount, the canceling amount, the average waiting time and the like in the latest preset time. For the preset area range and the latest preset time, reference may be made to the related description in step 301 above.
The historical willingness and like preference characteristics of the passenger 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 picking time period, and the like. For example, the preset history duration may be the last 20 days, 30 days, and the like, and the same history time period may be the same history time period of previous 1 day, 2 days, 5 days, and the like, which is not limited in this embodiment of the present invention.
In an alternative embodiment, a duration estimation model for estimating the countdown duration may be trained in advance. In the training process, a large amount of first sample data are obtained, wherein each first sample data comprises sample current supply and demand characteristics, sample passenger historical wish and other preference characteristics corresponding to a sample bill of lading, and labeling information of actual waiting time of the sample bill of lading. Training the to-be-trained time length estimation model by adopting a machine learning algorithm based on a large amount of first sample data, taking the current supply and demand characteristics of the sample bill of lading and the preference characteristics of the historical wishes and the like of the sample passenger as the input of the to-be-trained time length estimation model, and obtaining the sample estimated countdown time length of the sample bill of lading output by the to-be-trained time length estimation model. And calculating the loss value based on the labeled information of the sample estimation countdown time length of the sample bill and the actual waiting time length of the sample bill. When the loss value meets a preset condition (for example, the loss value is within a preset range), the training is determined to be completed, and the trained model is used as a duration estimation model.
Accordingly, the process of calculating the countdown duration of the display based on the current supply and demand characteristics and the preference characteristics of the passenger such as historical willingness may include: and taking the current supply and demand characteristics and the preference characteristics such as the historical wish and the like as the input of a pre-trained duration estimation model, and taking the output of the duration estimation model as the countdown duration. The time length output by the time length estimation model represents the time length equal to the wish of the passenger (namely the time length that the passenger is willing to wait), so the output of the time length estimation model is used as the countdown time length displayed, and the current supply and demand characteristics and the wish of the passenger can be met. The duration estimation model is obtained based on a large number of sample training, and the countdown duration can be acquired more accurately and more quickly by using the duration estimation model.
In an optional embodiment, since the duration estimation model has a certain uncertainty, the estimated countdown duration may deviate from the actual situation more greatly, and therefore, the countdown duration may be further corrected. In the implementation, a reasonable minimum time and a reasonable maximum time are preset, and when the countdown time is less than the preset minimum time, the countdown time is corrected to be the minimum time; and when the countdown duration is greater than the preset maximum duration, correcting the countdown duration to be the maximum duration, so that the countdown duration is ensured to be in a reasonable range.
Any suitable value may be selected for the specific values of the minimum duration and the maximum duration according to practical experience, which is not limited in the embodiment of the present invention. For example, the minimum duration may be 3 seconds, 5 seconds, etc., and the maximum duration may be 10 seconds, 15 seconds, etc.
And step 304, judging whether the counting down duration is successfully calculated. If yes, go to step 305; if not, go to step 306.
And when the counting down duration is successfully calculated, the server generates a counting down display instruction, wherein the counting down display instruction can carry the counting down duration obtained by calculation. And the server side sends the countdown display instruction carrying the countdown duration to the client side. And after receiving the countdown display instruction, the client responds to the countdown display instruction, pops up a countdown card, and starts to count down according to the countdown duration carried in the countdown display instruction.
And step 306, when the counting of the countdown duration fails, sending a countdown display instruction carrying a preset default countdown duration to the client.
In implementation, the countdown duration calculation may fail due to a failure of the duration estimation model or a failure of the server side system. Therefore, in the embodiment of the present invention, a default countdown duration may be preset. For example, the server may set a default countdown duration after receiving a passenger order taking request sent by the client; the server side can also set default countdown duration after the bill raising 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 the specific value of the default countdown duration, the embodiment of the present invention is not limited, for example, the default countdown duration may be set to the minimum duration mentioned in step 303.
When the counting down time length is failed to be calculated, the server side generates a counting down display instruction, and the counting down display instruction can carry preset default counting down time length. And the server side sends the countdown display instruction carrying the default countdown duration to the client side. And after receiving the countdown display instruction, the client responds to the countdown display instruction, pops up a countdown card, and starts to count down according to the default countdown duration carried in the countdown display instruction.
And 307, matching the bill raising request with a target driver and dispatching the target driver after judging that the countdown is not displayed.
If the countdown is not shown in the step 302, the server matches the bill lifting request with a target driver and dispatches the bill to the target driver.
In an alternative embodiment, the process of dispatching a target driver for matching the bill of lading request to the target driver may include: acquiring the number of drivers responding to the bill of lading request; taking the driver as a target driver and dispatching the target driver in the case that only one driver responds to the bill raising request; under the condition that a plurality of drivers respond to the bill raising request, respectively calculating the weight value of each driver, matching and obtaining 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, and dispatching the target driver.
Alternatively, the process of calculating the weight value of any driver may include the following steps B1 to B2:
and step B1, acquiring the pickup time length, the pickup distance and the order dispatching success rate of any driver.
The server side can obtain information such as the driving receiving duration and the driving receiving distance of any driver according to the current position of any driver responding to the bill lifting request and the starting position of the bill lifting request.
In an alternative embodiment, an order rate prediction model for predicting the order rate of the driver may be pre-trained. In the training process, a large amount of second sample data is obtained, wherein each second sample data comprises sample historical order information of a driver, sample order information and passenger sample historical order information corresponding to a sample order, and marking information of whether the sample order is finished or not. And training the to-be-trained order-picking rate estimation model by adopting a machine learning algorithm based on a large amount of second sample data, taking the sample historical order information of the driver, the sample order-picking information and the sample historical order information of the passenger as the input of the to-be-trained order-picking rate estimation model, and obtaining the sample estimated order-picking rate of the sample order-picking output by the to-be-trained order-picking rate estimation model. Based on the sample estimation order-dispatching success rate of the sample order and the labeling information of whether the sample order is successful or not, the loss value can be calculated. When the loss value meets a preset condition (for example, the loss value is within a preset range), the training is determined to be completed, and the trained model is used as an order dispatching and order forming rate estimation model.
Therefore, the process of obtaining the order forming rate of any one driver may include: acquiring historical order information of any driver, order-picking information of the order-picking request and historical order information of the passenger; and taking the historical order information of any driver, the order-taking information of the order-taking request and the historical order information of the passenger as the input of a pre-trained order-taking rate estimation model to obtain the order-taking rate of any driver output by the order-taking rate estimation model. The order delivery success rate estimation model is obtained based on a large number of sample training, and the order delivery success rate estimation model is utilized, so that the order delivery success rate of a driver can be obtained more accurately and more quickly.
The driver's historical order information may include historical pick-up amount, historical cancellation amount, historical complaint rate, and the like of the driver.
