In addition, the storage unit 42 manages a driver information database that manages information about drivers registered in the vehicle dispatch service, a sleep information database that manages sleep information, an evaluation result database that manages evaluation results, and service contents. It stores the service content database.

The driver information database stores information about the driver in association with information about the vehicle. Information about the driver includes, for example, driver identification information that identifies the driver registered in the vehicle dispatch service, terminal identification information that identifies the driver terminal 2, name, years of driving, unit price of distance or time set by the driver, and driver dispatch. History etc.

The sleep information database stores the driver identification information and the sleep information measured by the measuring device 1 for each measurement day indicating the day measured by the measuring device 1. The sleep information includes a plurality of measurement items (sleep time, information on non-REM sleep / REM sleep, etc.). Details of the evaluation result database and the service content database will be described later.

The control unit 43 is, for example, a CPU (Central Processing Unit). By executing the program stored in the storage unit 42, the control unit 43 executes the vehicle information acquisition unit 431, the sleep information acquisition unit 432, the determination unit 433, the evaluation unit 434, the determination unit 435, the transmission unit 436, and the notification unit. Functions as 437.

The sleep information acquisition unit 432 acquires the sleep information measured by the measuring device 1 from one or more driver terminals 2 used by each of the one or more drivers registered in the vehicle dispatch service via the communication unit 41. The sleep information acquisition unit 432 acquires sleep information from the driver terminal 2 used by the driver, for example, when the driver sets to start the business related to the vehicle dispatch service. The sleep information acquisition unit 432 inputs one or more sleep information acquired from one or more driver terminals 2 to the determination unit 433.

The determination unit 433 determines whether or not the sleep information acquired by the sleep information acquisition unit 432 is the sleep information corresponding to the driver himself / herself, based on the identification information that can identify the driver included in the sleep information. .. The determination method performed by the determination unit 433 will be described later. The determination unit 433 stores one or more sleep information determined to correspond to the driver himself / herself in the sleep information database.

The vehicle information acquisition unit 431 acquires information about one or more vehicles based on the input information acquired from the communication terminal 3. The input information is the information input by the user on the search screen of the vehicle dispatch service. In the case of a service for transporting passengers, the input information includes departure point information indicating the position of the departure point, arrival point information indicating the position of the arrival point, departure time, and the like. In addition, the input information includes departure point information, arrival point information, cargo size, cargo type, and the like in the case of a service for transporting cargo.

Specifically, the vehicle information acquisition unit 431 starts from the position indicated by the departure point information included in the input information acquired from the communication terminal 3 among the plurality of vehicles driven by each of the plurality of drivers registered in the vehicle allocation service. Acquire information about one or more vehicles existing within a predetermined range. The predetermined range is preset in the distance that can reach the departure point by the departure time included in the input information, the distance that can reach the departure point within the predetermined time (for example, 5 minutes), or the information providing device 4. The distance (for example, 1 km) and the like.

The vehicle information acquisition unit 431 first acquires input information from the communication terminal 3 via the communication unit 41, for example. Further, the vehicle information acquisition unit 431 acquires position information indicating the position of the driver terminal 2 from a plurality of driver terminals 2 registered in the vehicle allocation service via the communication unit 41. The vehicle information acquisition unit 431 identifies one or more driver terminals 2 existing within a predetermined range from the position indicated by the departure point information based on the acquired plurality of position information. Then, the vehicle information acquisition unit 431 acquires information on one or more vehicles corresponding to each of the specified one or more driver terminals 2 from the driver information database. The vehicle information acquisition unit 431 inputs one or more driver identification information corresponding to each of the specified one or more driver terminals 2 to the sleep information acquisition unit 432.

The sleep information acquisition unit 432 acquires one or more sleep information which is information on the sleep of each of the one or more drivers who can drive one or more vehicles. Specifically, the sleep information acquisition unit 432 acquires one or more sleep information associated with each of the one or more driver identification information input from the vehicle information acquisition unit 431 from the sleep information database. The sleep information acquisition unit 432 inputs one or more sleep information acquired from the sleep information database to the evaluation unit 434.

The evaluation unit 434 evaluates the degree of danger when one or more drivers each drive a vehicle based on one or more sleep information input from the sleep information acquisition unit 432. Specifically, the evaluation unit 434 evaluates the degree of danger when one or more drivers each drive a vehicle based on one or more sleep information determined to be sleep information corresponding to the driver himself / herself. The degree of danger when a driver drives a vehicle is, for example, the probability of causing a traffic accident when the driver drives the vehicle. The evaluation method performed by the evaluation unit 434 will be described later. The evaluation unit 434 inputs the evaluation result of evaluating the degree of danger when one or more drivers each drive the vehicle to the determination unit 435.

The decision unit 435 determines the content of the service that the driver can provide based on the evaluation result evaluated by the evaluation unit 434. The content of the service is, for example, the fare (including the reference fare for the fare based on the unit price set by the driver), the mileage, the mileage, and the like when the service for transporting passengers is performed. In addition, the content of the service is, for example, the type of freight, the required time, the freight, etc. in the case of providing a service for transporting freight. The method of determining the service content performed by the determination unit 435 will be described later. The determination unit 435 inputs the content of the determined service to the transmission unit 436.

The transmission unit 436 transmits to the communication terminal 3 the selection candidate information in which the information about one or more vehicles acquired by the vehicle information acquisition unit 431 and the evaluation result evaluated by the evaluation unit 434 are associated with each other via the communication unit 41. do. The transmission unit 436 may transmit the selection candidate information further associated with the content of the service determined by the determination unit 435 to the communication terminal 3. Specifically, the transmission unit 436 uses the communication unit 41 to acquire information about one or more vehicles acquired by the vehicle information acquisition unit 431, the evaluation result evaluated by the evaluation unit 434, and the service determined by the determination unit 435. The selection candidate information associated with the contents of is transmitted to the communication terminal 3. The transmission unit 436 may transmit selection candidate information further associated with one or more sleep information acquired by the sleep information acquisition unit 432 to the communication terminal 3.

The notification unit 437 acquires user selection information from the communication terminal 3 via the communication unit 41. The user selection information is information indicating one vehicle selected by the user among one or more vehicles included in the selection candidate information on the selection candidate screen of the vehicle allocation service displayed based on the selection candidate information. The user selection information includes terminal identification information and driver identification information of the driver terminal 2 used by the driver who drives one selected vehicle. The terminal identification information is, for example, a telephone number, an e-mail address, a MAC address, or the like. When the notification unit 437 acquires the user selection information from the communication terminal 3, the user requests the driver terminal 2 indicated by the terminal identification information included in the acquired user selection information via the communication unit 41 to dispatch the vehicle. Notify that. Further, when the user selection information is acquired from the communication terminal 3, the notification unit 437 is attached to the driver terminal 2 indicated by the terminal identification information stored in the storage unit 42 in response to the driver identification information acquired via the communication unit 41. , The user may notify that there is a request for vehicle allocation.

[Judgment method]
Subsequently, the determination method performed by the determination unit 433 will be described. When disclosing the driving risk evaluated based on the driver's sleep information in the vehicle dispatch service, it is not possible to provide the user with a service in consideration of safety unless the sleep information corresponds to the driver himself / herself. Therefore, the determination unit 433 determines whether or not the sleep information is the sleep information corresponding to the driver himself / herself, based on the identification information that can identify the driver included in the sleep information. The identification information is, for example, a pattern of pressure distribution measured from a mattress.

FIG. 3 is a diagram schematically showing a pattern of pressure distribution. The mattress, which is the measuring device 1, is a mat that can measure the distribution of pressure applied by a sleeping person. The mattress measures, for example, the pressure distribution as shown in FIG. 3 (b) when a person is lying on his back as shown in FIG. 3 (a). The pressure distribution D1 indicates a region where the pressure on the mattress is high. The pressure distribution D2 indicates a region where the pressure on the mattress is low.

For example, in the person shown in FIG. 3, the pressure distribution D1 is distributed on the lower side of the head, the upper right side of the back, the center of the buttocks, and the vicinity of the heels of both feet, and the pressure distribution D2 is on the lower side of the head and the back. It has a pattern distributed on the upper side, the entire buttocks, both elbows, the back thighs of both feet, and the vicinity of the heel. The mattress measures the pressure distribution, for example, when it detects that the driver is lying on its back, or when the button for measuring the pressure distribution is clicked in a dedicated application pre-installed on the driver terminal 2.

The sleep information acquisition unit 432 acquires sleep information including the pressure distribution measured by the mat as shown in FIG. 3 (b). Then, the determination unit 433 determines whether or not the sleep information is the sleep information corresponding to the driver himself / herself, based on the patterns of the pressure distributions D1 and D2 included in the sleep information acquired by the sleep information acquisition unit 432. Specifically, the determination unit 433 compares the patterns of the pressure distributions D1 and D2 included in the sleep information acquired by the sleep information acquisition unit 432 with the pressure distribution pattern of the driver stored in the storage unit 42 in advance. Therefore, it is determined whether or not the sleep information is the sleep information corresponding to the driver himself / herself.

The identification information may be, for example, a pulse measured from a mattress or wearable device. In this case, the determination unit 433 may determine whether or not the sleep information is the sleep information corresponding to the driver himself / herself, based on the pulse included in the sleep information. Specifically, the determination unit 433 compares the pulse pattern included in the sleep information with the driver's pulse pattern stored in the storage unit 42 in advance, so that the sleep information corresponds to the driver himself / herself. It may be determined whether or not it is.

The identification information may be, for example, sleep information measured before the day before the sleep information to be determined. For example, if one day's sleep time and the previous day's sleep time are the same or close, it is likely that the time, proportion, and number of non-REM sleep / REM sleep will be similar. Therefore, the determination unit 433 tells the driver himself / herself by comparing the sleep information of the determination target with the sleep information acquired from the same driver terminal 2 as the driver terminal 2 from which the determination target sleep information was acquired. It may be determined whether or not it is the corresponding sleep information.

The identification information may be, for example, a pre-registered driver terminal 2. The determination unit 433 may determine whether or not the sleep information corresponds to the driver himself / herself by comparing the terminal identification information registered in advance with the terminal identification information included in the sleep information. By determining whether or not the determination unit 433 is the sleep information corresponding to the driver himself / herself in this way, it is possible to prevent a situation in which the sleep information not corresponding to the driver is disclosed to the user.

[Evaluation method]
Subsequently, the evaluation method performed by the evaluation unit 434 will be described. As described above, the evaluation unit 434 evaluates the degree of danger when one or more drivers each drive a vehicle based on one or more sleep information. For example, the evaluation unit 434 classifies each one or more sleep information into ranks based on a predetermined classification standard, and each one or more drivers drives the vehicle based on the one or more sleep information classified into the ranks. Evaluate the degree of risk in the case. The predetermined classification criteria are, for example, in the measurement item of sleep time, when the sleep time is 7 hours or more and less than 8 hours, it is classified into the best rank, and when the sleep time is less than 4 hours, it is the best. It is classified as a bad rank. The evaluation unit 434 stores the evaluation result of evaluating the degree of danger when the driver drives the vehicle in the evaluation result database.

FIG. 4 is a diagram showing the structure of the evaluation result database. As shown in FIG. 4, the evaluation result database associates the driver identification information that identifies the driver registered in the vehicle dispatch service with the measurement date indicating the date measured by the measuring device 1 and the evaluation based on the sleep information. I remember. The plurality of measurement items of the evaluation shown in FIG. 4 are classified into five ranks from 1 to 5. The overall evaluation shown in FIG. 4 shows the overall evaluation classified into five ranks from A to E.

The evaluation unit 434 performs a comprehensive evaluation based on a predetermined evaluation standard. The predetermined evaluation criteria are, for example, in each of a plurality of measurement items, when the ratio of 3 to 5 is 0%, the comprehensive evaluation is set to "A", and when the ratio of 4 and 5 is 10% or more, the comprehensive evaluation is set. For example, "E".

By the way, for example, even if the evaluations based on the two sleep information corresponding to each of the two drivers are the same, there is a possibility of causing a traffic accident depending on the type of vehicle the driver drives or the function of the vehicle. May be higher or lower. For example, if the vehicle driven by driver A, who has the same evaluation, is a large vehicle and does not have a driving control function, he / she must drive more carefully than a normal vehicle, so there is a possibility of causing a traffic accident. It is possible that the price will be higher than when driving a medium-sized or smaller vehicle. On the other hand, if the vehicle driven by driver B having the same evaluation is a small vehicle and has an automatic braking function as a driving control function, the possibility of causing a traffic accident is lower than that of the vehicle driven by driver A. Can be considered.

Therefore, the evaluation unit 434 may evaluate the degree of danger when one or more drivers each drive a vehicle based on one or more sleep information and information on one or more vehicles. By doing so, the evaluation unit 434 can provide the user with information in consideration of safety more accurately.

The evaluation unit 434 compares the sleep information acquired by the sleep information acquisition unit 432 with a sleep index based on a plurality of sleep information stored in the sleep information database, whereby one or more drivers drive the vehicle. The degree of risk may be evaluated. The sleep index is, for example, a plurality of sleep information corresponding to each of a plurality of other drivers different from the one or more drivers to be evaluated. In this case, the evaluation unit 434 evaluates the degree of danger when one or more drivers each drive the vehicle by comparing the one or more sleep information acquired by the sleep information acquisition unit 432 with the sleep index. You may.

For example, in the case of evaluating the degree of risk based on the sleep information corresponding to the driver (hereinafter referred to as driver A) indicated by the driver identification information "D1111" measured on the measurement date "2017/4/2" shown in FIG. It is assumed that the sleep information corresponding to the driver (hereinafter referred to as driver B) indicated by the driver identification information "D2222" measured on the measurement date "2017/4/1" is used as the evaluation index. At this time, as shown in FIG. 4, the evaluation unit 434 classifies each of the plurality of measurement items included in the sleep information acquired by the sleep information acquisition unit 432 into five ranks.

In this case, the evaluation unit 434 is better than the driver B with respect to the driver A because each of the plurality of measurement items corresponding to the driver A has a higher rank than each of the plurality of measurement items corresponding to the driver B. Make an evaluation. By doing so, it is possible to prevent the evaluation unit 434 from evaluating the sleep information better than that of the other driver but lower than that of the other driver.

The evaluation unit 434 weights one or more measurement items associated with a factor causing a traffic accident among a plurality of measurement items included in the one or more sleep information acquired by the sleep information acquisition unit 432. The degree of risk when one or more drivers each drive a vehicle may be evaluated based on the above. Specifically, the evaluation unit 434 first, among a plurality of measurement items included in the sleep information acquired by the sleep information acquisition unit 432, with respect to one or more measurement items associated as factors causing a traffic accident. Weight each driver attribute. Then, the evaluation unit 434 may evaluate the degree of danger when one or more drivers each drive the vehicle based on the weighted one or more sleep information. The attributes of the driver are, for example, the health status of the members (obesity, chronic illness, etc.), the driving ability of the driver (driving frequency, years of driving, traffic violation history, etc.).

FIG. 5 is a diagram schematically showing weighting for each attribute of the driver. As shown in FIG. 5, the weighting is set for each of the plurality of measurement items included in the sleep information for each attribute of the driver. For example, an obese person may have Sleep Apnea Syndrome (SAS), which blocks the airways during sleep and temporarily prevents breathing. In this case, the quality of sleep deteriorates (for example, REM sleep time decreases), sudden loss of consciousness while driving, or loss of attention due to being attacked by strong sleep may cause a traffic accident. Highly sexual. Therefore, for obese drivers, a higher weighting (for example, twice) than usual is set for the measurement item of REM sleep time. By setting the weighting for each measurement item in this way, the evaluation unit 434 can improve the accuracy of evaluating the degree of danger when the driver drives the vehicle.

In addition, the degree of risk of driving evaluated by the evaluation unit 434 may not be accurately evaluated with the sleep information for one day. For example, a driver A who has a daily sleep time of 4 hours or less has a sleep time of 7 hours only on a certain day, and a driver B who has a daily sleep time of 7 hours has a sleep time of 7 hours on a certain day. Even if the sleep time is the same, the risk of driving is different from the case where the time is the same. Therefore, the evaluation unit 434 is based on a plurality of sleep information acquired over a predetermined period of time and a plurality of sleep information determined to be sleep information corresponding to the driver himself / herself. You may evaluate the degree of risk when driving a vehicle. By doing so, the evaluation unit 434 can improve the accuracy of evaluating the degree of danger when the driver drives the vehicle.

[How to determine service content]
Subsequently, a method of determining the service content performed by the determination unit 435 will be described. As described above, the content of the service that the driver can provide is determined based on the evaluation result evaluated by the evaluation unit 434. The determination unit 435 determines, for example, the mileage that the driver can drive based on the evaluation result evaluated by the evaluation unit 434. The determination unit 435 inputs the content of the determined service to the transmission unit 436, and stores the content of the determined service in the service content database.

FIG. 6 is a diagram showing the configuration of the service content database. As shown in FIG. 6, the service content database stores the driver identification information, the determination date indicating the date when the service content is determined, and the service content (for example, the mileage) in association with each other. For example, when the evaluation is "A", the determination unit 435 determines "unlimited" which has the longest mileage, and when the evaluation is "B", determines "within 100 km". The mileage shown in FIG. 6 may be indicated by a numerical value or by region (for example, within the Kanto region, within an adjacent prefecture, etc.).

The decision unit 435 is based on the relationship between the past evaluation result evaluated by the evaluation unit 434 at the time of determining the content of the service and the current evaluation result evaluated by the evaluation unit 434 at the time of determining the content of the service. You may decide the content of the service. Specifically, the determination unit 435 may determine the content of the service based on the degree of improvement of the current evaluation result, which is improved from the past evaluation result at the time when the content of the service is determined immediately before. More specifically, the determination unit 435 may determine the content of the service based on the degree of improvement of the current evaluation result, which is improved from the past evaluation result at the time when the content of the service is determined immediately before. ..

For example, as the content of the service for driver A indicated by the driver identification information "D1111" on April 2, 2017, when determining the mileage, as shown in FIG. 6, on April 1, 2017, the day before. Assume that the rating is "B" and the rating on April 2, 2017 is "A". In this case, since the evaluation on April 2, 2017 is improved from the evaluation on April 1, 2017 on the previous day, the determination unit 435 is based on the mileage determined on April 1, 2017. Also determines the long mileage.

By the way, a driver with a low evaluation such as "D" or "E" has a high possibility of causing a traffic accident due to a decrease in attention due to lack of sleep. If a vehicle driven by such a driver runs on a highway, it may cause a serious traffic accident. Therefore, the determination unit 435 may determine the classification of the road on which the driver can drive based on the evaluation result evaluated by the evaluation unit 434.

In addition, when the driver sets the unit price of distance or time, the determination unit 435 determines the arrival point indicated by the arrival point information from the position of the departure point indicated by the departure point information as a reference charge for the fare based on the unit price set by the driver. You may decide the fare to the position of.

In addition, when a driver transports cargo, if the type of cargo is fragile, such as precision equipment or works of art, it is necessary to drive with care so that the cargo does not move. Therefore, the determination unit 435 may determine the type of cargo that the driver can carry based on the evaluation result evaluated by the evaluation unit 434. The determination unit 435 determines, for example, that a fragile cargo can be carried when the evaluation is "B" or higher, and can carry a fragile cargo when the evaluation is "C" or lower. Decide what you can't do. The determination unit 435 inputs the content of the determined service to the transmission unit 436.

When the content of the service is input from the determination unit 435, the transmission unit 436 determines the content of the service (travelable distance, road classification, cargo type, etc.) determined by the determination unit 435 via the communication unit 41.
