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 needing care increases rapidly. If even elderly people with high vehicle driving safety return their driver's licenses, there is a risk that it will be 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 the like in a persuasive manner.

Means for Solving the Problems

[0007] In order to solve the above problems,

[0008] Furthermore, from another perspective of the present invention, a vehicle driving safety comparison program and a vehicle driving safety comparison method corresponding to the above-described vehicle driving safety comparison system are provided. [Effects of the Invention]

[0009] The vehicle driving safety comparison system of the present invention makes it possible to compare the driving safety of elderly people and others in a convincing manner. [Brief explanation of the drawing]

[0010] [Figure 1] Diagram illustrating a registered road according to an embodiment of the present invention. [Figure 2] Block diagram of a vehicle driving safety comparison system according to an embodiment of the present invention. [Figure 3] Diagram illustrating the rule application position according to an embodiment of the present invention. [Modes for carrying out the invention]

[0011] The vehicle driving safety comparison system 1 according to an embodiment of the present invention will be described below with reference to Figures 1-3.

[0012] As shown in Figure 1, the Vehicle Driving Safety Comparison System 1 is designed to compare the frequency of traffic rule violations occurring on registered roads X between a target vehicle Y driven by elderly drivers and multiple sample vehicles Z driven by drivers of other age groups (hereinafter referred to as "non-elderly drivers").

[0013] As shown in Figure 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] Memory unit 2 stores road location information for each location on multiple registered roads X, and multiple traffic rules established for vehicles traveling on each registered road X.

[0015] As the registered road X, it is preferable to remember as many roads as possible. For example, it is conceivable to remember 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 that the memory unit 2 remembers the latitude and longitude of the range included in each registered road X.

[0017] As traffic rules, rules indicated by road signs (regulation signs, direction signs, auxiliary signs), road markings (regulation markings, direction markings), etc. can be considered. As the latitude and longitude of the rule application positions where 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 that the memory unit 2 remembers 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 on data, but for easy 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 where a predetermined speed limit is applied form a point set range A, the latitude and longitude of a plurality of rule application positions where a stop is applied form a point set range B, and the latitude and longitude of a plurality of rule application positions where parking is prohibited form a point set range C.

[0019] Also, the memory unit 2 is to pre-remember in advance the age information of the driver of the target vehicle Y and the age information of the drivers of each sample vehicle Z.

[0020] The acquisition unit 3 can acquire travel information regarding the travel position of a vehicle traveling 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. 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. 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 applicable 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 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. 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 two target position information by the time between them.

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

[0028] In terms of violation frequency, one could calculate the number of violations per trip on a single registered road X, or the number of violations per unit of time spent traveling on a single registered road X.

[0029] For example, if multiple sample vehicles Z traveled on a single registered road X a total of 10,000 times in the last three months, and the first judgment unit 4 determined that a traffic rule violation occurred a total of 1,000 times, then the first violation frequency would be calculated as 0.1.

[0030] On the other hand, if the vehicle Y in question traveled on the single registered road X 100 times in the last three months, and the first judgment unit 4 determined that it was in violation of traffic rules 5 times, then the second violation frequency would be calculated as 0.05.

[0031] Thus, in this embodiment, the first frequency of traffic rule violations by non-elderly drivers and the second frequency of traffic rule violations by elderly drivers are calculated, making it possible to convincingly compare the safety of vehicle driving by elderly drivers and others.

[0032] Furthermore, since some registered roads X are more prone to traffic rule violations than others, simply comparing the average of non-elderly traffic rule violations occurring on all registered roads X with the average of traffic rule violations committed by the elderly person on the registered roads X they traveled on would not accurately compare the safety of elderly drivers. However, in this embodiment, the first and second violation frequencies are calculated for each registered road X, making it possible to accurately compare the safety of elderly drivers.

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

[0034] In the above example, since the frequency of the second violation is less than the frequency of the first violation, it is conceivable that the driving of the target vehicle Y (in this embodiment, the driving by an elderly person) would be judged as "safe."

[0035] The second determination unit 6, in determining the driving safety of the driver of the target vehicle Y, preferably makes a determination for each registered road X that the target vehicle Y traveled on during a predetermined period, and makes an overall safety determination based on the results of each determination (for example, by adding them together). In this case, it is conceivable to make the determination according to the number or proportion of registered roads X that are determined to be "safe". For example, if all registered roads X are determined to be "safe", the overall safety may also be determined to be "safe", which makes it possible to compare the driving safety of elderly people and others in a more convincing way.

[0036] Furthermore, in order to compare the safety of vehicle driving among the elderly and others in a more convincing manner, it is preferable that the second frequency of violations involving the elderly is significantly better than the first frequency of violations involving non-elderly drivers.

[0037] Therefore, in this embodiment, the second determination unit 6, in determining the driving safety of the driver of the target vehicle Y, also takes into consideration the degree of difference between the first violation frequency and the second violation frequency.

[0038] For example, if the frequency of the second violation is less than or equal to a predetermined value than the frequency of the first violation, it may be judged as "safe." Alternatively, if the frequency of the second violation is less than or equal to a predetermined percentage of the frequency of the first violation, it may also be judged as "safe."

[0039] As described above, the vehicle driving safety comparison system 1 according to this embodiment calculates a first frequency of traffic rule violations determined on a single registered road X during a predetermined period for multiple sample vehicles Z driven by drivers within a predetermined age range, and a second frequency of traffic rule violations determined on the same registered road X during the same predetermined period for target vehicles Y driven by drivers older than the predetermined age range.

[0040] This configuration allows for the calculation of the first frequency of traffic rule violations by non-elderly drivers and the second frequency of traffic rule violations by elderly drivers, making it possible to convincingly compare the safety of vehicle driving by elderly drivers. Furthermore, since the first and second violation frequencies are calculated for each registered road X, it becomes possible to accurately compare the safety of vehicle driving by elderly drivers. As a result, if the safety of vehicle driving by elderly drivers is not evaluated favorably, it becomes possible to convincingly encourage the surrender of their driver's license. On the other hand, if the safety of vehicle driving by elderly drivers is evaluated favorably, it provides reassurance to the public and their relatives regarding the elderly person's driving, and allows the elderly person to continue driving, thus enabling them to maintain a healthy lifestyle.

[0041] Furthermore, in the vehicle driving safety comparison system 1 according to this embodiment, when determining the driving safety of the driver of the target vehicle Y, the degree of difference between the first violation frequency and the second violation frequency is also taken into consideration.

[0042] With this configuration, if the second violation frequency related to the elderly is significantly better than the first violation frequency related to non-elderly drivers, it can be determined to be "safe," making it possible to assess the safety of vehicle driving by the elderly and others in a more convincing manner.

[0043] Furthermore, in the vehicle driving safety comparison system 1 according to this embodiment, when determining the driving safety of the driver of the target vehicle Y, a determination is made for each registered road X that the target vehicle Y traveled on during a predetermined period, and an overall safety determination is made based on the results of each determination.

[0044] This configuration makes it possible to compare the safety of vehicle driving among the elderly and others in a more compelling way.

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

[0046] For example, elderly drivers often worry about mistaking the accelerator for the brake. However, if the target vehicle Y, which is driven by elderly people, is equipped with a pedal misapplication prevention function, this worry can be alleviated.

[0047] Therefore, in the above embodiment, the second determination unit 6 may also consider the safety equipment of the target vehicle Y when determining the safety of the driving by the driver of the target vehicle Y.

[0048] In this case, the memory unit 2 stores not only the age information of the driver of the target vehicle Y, but also the presence and type of safety equipment (such as pedal misapplication prevention function and collision prevention function) of the target vehicle Y. For example, even if there is a registered road X where the second violation frequency is slightly higher than the first frequency, if safety equipment is installed, the second judgment unit can determine that "the driver of the target vehicle Y is driving safely." Furthermore, when considering the degree of difference between the first and second violation frequencies, it is conceivable to add numerical values ​​corresponding to the presence and type of safety equipment to the difference.

[0049] Furthermore, in the case of elderly drivers, speeding violations may pose a greater risk than for non-elderly drivers due to issues with reflexes and other factors. Therefore, when the second judgment unit 6 determines the safety of the driving by the driver of the target vehicle Y, it is conceivable that it may also consider the type of traffic rule violation committed by the target vehicle Y.

[0050] For example, if there is a significant speed violation exceeding a predetermined value during a predetermined period, or if there is a speed violation exceeding a predetermined number of times during a predetermined period, the second determination unit may determine that "the driver of the target vehicle Y is not driving safely."

[0051] Furthermore, in the above embodiment, the second determination unit 6 determined the driving safety of 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 and second violation frequencies calculated by the calculation unit 5, it is not necessarily required for the second determination unit 6 to make a determination.

[0052] Furthermore, the vehicles in the above embodiment are not limited to automobiles, but also include motorcycles and the like. In that case, the first and second violation frequencies may be calculated for each type of vehicle.

[0053] Furthermore, in the above embodiment, the “latitude and longitude of the rule application location to which the predetermined traffic rule applies” of the present invention was based on decision-making data issued by the Public Safety Commission, police station, etc., but data obtained from other sources may also be used.

[0054] Furthermore, the present invention can also be applied to programs corresponding to the processing performed by a vehicle driving safety comparison system, and to recording media that store such programs. In the case of recording media, the program will be installed on a computer or the like. Here, the recording media that stores the program may be a non-transient recording media. Examples of non-transient recording media include CD-ROMs, but the invention is not limited to them.

[0055] A computer consists of a CPU, memory, and a hard disk. The program is stored on the hard disk, loaded into memory at runtime, and processed by the CPU. The computer's CPU may be capable of parallel processing, and the computer itself may be configured for distributed processing. The processing results can be displayed on any display via a network.
