Summary of the Invention

Problems to be Solved by the Invention

[0004] These days, the safety of elderly people's vehicle driving has been regarded as a problem. Although it is possible to evaluate the safety of elderly people's vehicle driving using the above technology, even if it is evaluated that "the safety of vehicle driving is high", there is a situation where the driver's license is returned due to the voices of the society and relatives.

[0005] However, it is also known that returning the driver's license reduces the living range and the risk of requiring care increases rapidly. If even elderly people with high vehicle driving safety return their driver's licenses, there is a risk that it will become difficult to continue a healthy life.

[0006] Therefore, an object of the present invention is to provide a vehicle driving safety comparison system capable of comparing the vehicle driving safety of the elderly and others in a persuasive manner.

Embodiments for Carrying Out the Invention

[0011] Hereinafter, a vehicle driving safety comparison system 1 according to an embodiment of the present invention will be described with reference to FIGS. 1-3.

[0012] As shown in FIG. 1, the vehicle driving safety comparison system 1 is for comparing, for example, the frequency of traffic rule violations that occur on a registered road X between a target vehicle Y driven by an elderly person or the like and a plurality of sample vehicles Z driven by other age groups (hereinafter referred to as non-elderly).

[0013] As shown in FIG. 2, the vehicle driving safety comparison system 1 includes a storage unit 2, an acquisition unit 3, a first determination unit 4, a calculation unit 5, and a second determination unit 6.

[0014] The storage unit 2 stores road position information regarding each position of a plurality of registered roads X and a plurality of traffic rules defined for vehicles traveling on each registered road X.

[0015] As the registered road X, it is preferable to memorize as many roads as possible. For example, it is conceivable to memorize all the roads in Japan. Also, in the present embodiment, as shown in FIG. 1, each link is to be treated as the registered road X.

[0016] As the road position information, the latitude and longitude of each registered road X can be considered, and it is preferable to memorize in the storage unit 2 the latitude and longitude of the range in which each registered road X is included.

[0017] As traffic rules, rules indicated by road signs (regulation signs, guiding signs, auxiliary signs), road markings (regulation markings, guiding markings), etc. can be considered. As the latitude and longitude of the rule application positions to which these rules are applied, for example, those described in the decision-making data issued by the Public Safety Commission, police stations, etc. can be used. When the decision-making data is described by address, it is preferable to memorize in the storage unit 2 the information obtained by converting in advance the range included in the address into latitude and longitude.

[0018] These rule application positions do not need to be displayed like a map because they can be handled in terms of data. However, for ease of understanding, when the latitude and longitude of these rule application positions are displayed, it will be as shown in FIG. 3. In FIG. 3, the latitude and longitude of a plurality of rule application positions to which a predetermined speed limit is applied form a point set range A, the latitude and longitude of a plurality of rule application positions to which a stop is applied form a point set range B, and the latitude and longitude of a plurality of rule application positions to which parking is prohibited form a point set range C.

[0019] Also, in the storage unit 2, the age information of the driver of the target vehicle Y and the age information of the drivers of the respective sample vehicles Z are also to be memorized in advance.

[0020] The acquisition unit 3 can acquire travel information regarding the travel position of a vehicle that has traveled on the registered road X.

[0021] In this embodiment, the target vehicle Y and the sample vehicle Z are equipped with a detection device D capable of detecting its own position information in association with time information, and the acquisition unit 3 acquires the position information associated with the time information transmitted from the detection device D as travel information. It is preferable to sequentially acquire the travel information in a short span.

[0022] As the detection device D, it is conceivable to use a known GPS function, and a GPS device installed in the vehicle may be used, or the GPS function of the driver's smartphone or the like may be used.

[0023] Also, in this embodiment, the vehicle driving safety comparison system 1 is installed in a communication center or the like, and the communication with the detection device D is performed wirelessly.

[0024] The first determination unit 4 determines whether a vehicle violates traffic rules on the registered road X based on the travel information, the road position information, and the traffic rules.

[0025] Specifically, based on the road position information stored in the storage unit 2 and the position information included in the travel information, the registered road X on which the vehicle has traveled is determined, the traffic rules applied to the determined registered road X are extracted from the storage unit 2, and based on the extracted traffic rules and the acquired travel information, it is determined whether the vehicle violates the traffic rules.

[0026] As a method for determining whether there is a violation, for example, in the case of a speed violation, if the speed exceeds a predetermined value in a speed limit section (in the case of FIG. 3, the point set range A), it is determined as a violation, and in the case of a stop violation, if the vehicle does not stop for a predetermined time within a few meters before and after the stop position (in the case of FIG. 3, the point set range B), it is determined as a violation. The speed of the vehicle Y can be calculated by dividing the distance between the target two position information by the time between them.

[0027] The calculation unit 5 calculates, for a plurality of sample vehicles Z driven by drivers within a predetermined age range (excluding the elderly in this embodiment), a first violation frequency of traffic rule violations determined during a predetermined period on a single registered road X, and for a target vehicle Y driven by a driver of an age higher than the predetermined range (the elderly in this embodiment), a second violation frequency of traffic rule violations determined during the predetermined period on the single registered road X.

[0028] As the violation frequency, it is conceivable to calculate the number of violations per one run on the single registered road X or the number of violations per unit time of driving on the single registered road X.

[0029] For example, if a plurality of sample vehicles Z have traveled a total of 10,000 times on a single registered road X during the most recent three months, and among them, the total number of times determined to be traffic rule violations by the first determination unit 4 is 1,000 times, then the first violation frequency is calculated to be 0.1.

[0030] On the other hand, if the target vehicle Y has traveled 100 times on the single registered road X during the most recent three months, and among them, the total number of times determined to be traffic rule violations by the first determination unit 4 is 5 times, then the second violation frequency is calculated to be 0.05.

[0031] Thus, in this embodiment, since the first violation frequency of traffic rule violations by non-elderly people and the second violation frequency of traffic rule violations by the elderly are calculated, it becomes possible to compare the safety of vehicle driving by the elderly and the like in a persuasive manner.

[0032] In addition, since there are registered roads X where traffic rule violations are likely / unlikely to occur, simply comparing the average of traffic rule violations committed by non-elderly people on all registered roads X with the average of traffic rule violations committed by the elderly on the registered roads X on which the target elderly people drove would make it impossible to accurately compare the safety of vehicle driving by the elderly and others. However, in the present embodiment, since the first violation frequency and the second violation frequency are calculated for each registered road X, it becomes possible to accurately compare the safety of vehicle driving by the elderly and others.

[0033] The second determination unit 6 determines the safety of driving by the driver of the target vehicle Y by comparing the second violation frequency with the first violation frequency.

[0034] In the case of the above example, since the second violation frequency is less than the first violation frequency, it can be considered that the driving of the target vehicle Y (in the present embodiment, the driving of the elderly) is determined to be "safe".

[0035] When determining the safety of driving by the driver of the target vehicle Y, the second determination unit 6 preferably makes a determination for each registered road X on which the target vehicle Y has driven during a predetermined period, and determines the comprehensive safety based on each determination result (for example, addition, etc.). In this case, it is conceivable to make a determination according to the number or proportion of registered roads X determined to be "safe". For example, when it is determined to be "safe" on all registered roads X, it can be considered that the comprehensive safety is also determined to be "safe", thereby making it possible to compare the safety of vehicle driving by the elderly and others in a more persuasive manner.

[0036] In addition, in order to compare the safety of vehicle driving by the elderly and others in a more persuasive manner, it is preferable that the second violation frequency regarding the elderly is greater and better than the first violation frequency regarding non-elderly people.

[0037] Therefore, in the present embodiment, when determining the safety of driving by the driver of the target vehicle Y, the second determination unit 6 also considers the degree of difference between the first violation frequency and the second violation frequency.

[0038] For example, if the second violation frequency is less than a predetermined value or more than the first violation frequency, it may be determined as "safe". Also, if the second violation frequency is equal to or less than a predetermined ratio of the first violation frequency, it may be determined as "safe".

[0039] As described above, in the vehicle driving safety comparison system 1 according to the present embodiment, regarding a plurality of sample vehicles Z driven by drivers within a predetermined age range, the first violation frequency of traffic rule violations determined during a predetermined period on a single registered road X, and regarding the target vehicle Y driven by a driver older than the predetermined age range, the second violation frequency of traffic rule violations determined during the predetermined period on the single registered road X are calculated.

[0040] According to such a configuration, the first violation frequency of traffic rule violations by non-senior drivers and the second violation frequency of traffic rule violations by senior drivers are calculated, so it becomes possible to compare the safety of vehicle driving by senior drivers and the like in a persuasive manner. Also, since the first violation frequency and the second violation frequency are calculated for each registered road X, it becomes possible to accurately compare the safety of vehicle driving by senior drivers and the like. As a result, when the safety of vehicle driving by senior drivers and the like has not been evaluated, it becomes possible to encourage the return of the driving license in a persuasive manner. On the other hand, when the safety of vehicle driving by senior drivers and the like has been evaluated, it gives the public and relatives a sense of security regarding the driving of the senior driver, and it becomes possible to continue the healthy life of the senior driver by continuing to drive.

[0041] Also, in the vehicle driving safety comparison system 1 according to the present embodiment, when determining the safety of driving by the driver of the target vehicle Y, the degree of difference between the first violation frequency and the second violation frequency is also considered.

[0042] According to such a configuration, since it can be determined as "safe" when the second violation frequency regarding senior drivers is larger and better than the first violation frequency regarding non-senior drivers, it becomes possible to determine the safety of vehicle driving by senior drivers and the like in a more persuasive manner.

[0043] In addition, in the vehicle driving safety comparison system 1 according to the present embodiment, when determining the driving safety of the driver of the target vehicle Y, a determination is made for each registered road X on which the target vehicle Y has traveled during a predetermined period, and the overall safety is determined based on each determination result.

[0044] According to such a configuration, it becomes possible to compare the vehicle driving safety of the elderly and the like in a more persuasive manner.

[0045] Note that the vehicle driving safety comparison system of the present invention is not limited to the above-described embodiment, and various modifications and improvements are possible within the scope described in the claims.

[0046] For example, in the vehicle driving of the elderly, there is often anxiety about accidentally stepping on the accelerator instead of the brake. However, if the target vehicle Y driven by the elderly or the like is equipped with a function to prevent misoperation, such anxiety can also be reduced.

[0047] Therefore, in the above embodiment, when the second determination unit 6 determines the driving safety of the driver of the target vehicle Y, it is conceivable to also consider the safety equipment of the target vehicle Y.

[0048] In this case, in the storage unit 2, in addition to the age information of the driver of the target vehicle Y, the presence or absence and type (misoperation prevention function, collision prevention function, etc.) of the safety equipment of the target vehicle Y are stored. For example, even if there is a registered road X where the second violation frequency slightly exceeds the first frequency, if the safety equipment is installed, the second determination unit may be configured to determine that "the driver of the target vehicle Y is driving safely". In addition, when considering the degree of difference between the first violation frequency and the second violation frequency, it is also conceivable to add a numerical value or the like corresponding to the presence or absence and type of the safety equipment to the difference.

[0049] In addition, in the case of elderly people, due to problems with reflex nerves etc., exceeding the speed limit may carry a greater risk for the elderly than for others. Therefore, when determining the safety of the driving by the driver of the target vehicle Y, it is conceivable that the second determination unit 6 also takes into account the type of traffic rule violation of the target vehicle Y.

[0050] For example, in cases such as "there has been a significant speed exceeding by a predetermined value or more during a predetermined period" or "there has been a speed exceeding by a predetermined number of times or more during a predetermined period", it is also conceivable that the second determination unit determines that "the driver of the target vehicle Y is not driving safely".

[0051] In addition, in the above embodiment, the second determination unit 6 determines the safety of the driving by the driver of the target vehicle Y by comparing the second violation frequency with the first violation frequency. However, if the user can compare the first violation frequency and the second violation frequency calculated by the calculation unit 5, it is not necessarily required to perform the determination by the second determination unit 6.

[0052] In addition, the vehicle in the above embodiment is not limited to an automobile, and of course includes motorcycles etc. In that case, the first violation frequency and the second violation frequency may be calculated for each type of vehicle.

[0053] In addition, in the above embodiment, as the "latitude and longitude of the rule application position where a predetermined traffic rule is applied" of the present invention, data of decisions issued by the Public Safety Commission, police stations etc. is used, but data obtained from other sources may also be used.

[0054] In addition, the present invention is also applicable to a program corresponding to the processing performed by the vehicle driving safety comparison system and a recording medium storing the program. In the case of the recording medium, the program will be installed in a computer etc. Here, the recording medium storing the program may be a non-transitory recording medium. As the non-transitory recording medium, a CD-ROM etc. can be considered, but it is not limited thereto.

[0055] The computer consists of a CPU, memory, and hard disk. The program is recorded on the hard disk and expanded into the memory during execution, and the processing is performed by performing arithmetic processing on the CPU. Note that the CPU of the computer may be capable of parallel processing, or the computer itself may be in a form capable of distributed processing. The result of the processing can be displayed on an arbitrary display via a network.
