Based on the accident rate of the rapid acceleration section, the second weight value beta can be converted into '1'. Accordingly, the third weight γ can be converted into a value obtained by dividing the accident rate of the rapid deceleration section by the accident rate of the rapid acceleration section.

However, the present invention is not limited to this, and the dynamic safety index calculating unit 214_2 may determine the second and third weights? And? As the accident rate of the rapid deceleration section. On the basis of the accident rate of the rapid deceleration section, the third weight (γ) can be converted into '1'. In order to convert the second weight value beta based on the converted third weight value γ, the second weight value β may be calculated by dividing the accident rate of the rapid acceleration section by the accident rate of the rapid deceleration section.

The weights?,?,? Can be calculated based on the accident record data. The dynamic safety index calculating unit 214_2 may multiply the weights alpha, beta, and gamma by a speed index, an acceleration index, and a deceleration index, respectively. The dynamic safety factor calculation unit 214_2 may calculate the dynamic safety factor by summing all of the multiplied values.

The workload safety index calculating unit 214_3 can calculate the workload safety index based on the travel time data. The workload safety index calculating section 214_3 can receive information on the running times of the vehicles 100_1 to 100_q from the running time calculating section 213_3. The workload safety index can be a measure of safety based on the amount of time the driver has been driving the vehicle during the day. The workload safety index can be calculated based on the accident rate by vehicle operation time. Table 2 shows the accident rates of each vehicle. Table 2 provides an illustration of the results of a study on the relationship between travel time and accident rate reported by Goode in 2003. The information contained in Table 2 may be received from the accident history database 211.

Operating time (length of time) Accident rate The first operating time (1-3) 7.9 Second operating time (4-6) 8.4 Third operating time (7-9) 11.1 Fourth operating time (10-12) 16.5 Fifth operating time (13+) 56.2

Table 2 shows an example of accident rate information according to operating time. Referring to Fig. 2, as the travel time length of the vehicle increases, the accident rate tends to increase. In an embodiment of the present invention, in order to calculate the workload safety index, the workload safety index calculating section 214_3 may convert one of a plurality of accident rates into a reference value. In order to calculate the workload safety index, the workload safety index calculating unit 214_3 may consider only the running time (hour) of the vehicle. This is an embodiment of the present invention, and the workload safety index calculating unit 214_3 can calculate the safety index considering both the hours (hours), minute (minute), and seconds (second) of the vehicle.

 Illustratively, the workload safety index calculating section 214_3 may convert the accident rate (7.9) of the first operating time (1-3) to the reference workload safety index '1'. The workload safety index calculating section 214_3 can convert the remaining accident rates (8.4, 11.1, 16.5, 56.2) to the workload safety index based on the reference workload safety index "1".

Illustratively, the workload safety index of the second operating time 4-6 is calculated by dividing the accident rate 11.1 of the second operating time 4-6 by the accident rate 8.4 of the first operating time 1-3 Value (1.32). In this way, it is possible to calculate workload safety indices for each of the third to fifth operating times 7-9, ..., 13 +.

The workload safety index calculating section 214_3 can receive the running time data for each day of each of the vehicles 100_1 to 100_q from the running time calculating section 213_3. Depending on the operating times of the vehicles 100_1 to 100_q, the workload safety index calculating unit 214_3 can calculate the workload safety index. However, the present invention is not limited to this, and the workload safety index calculating unit 214_3 can calculate the dynamic safety index based on the operating time zone (morning, afternoon, or evening) of each of the vehicles 100_1 to 100_q.

The safety index calculating section 214 may output the static safety index, the dynamic safety index, and the workload safety index to the comprehensive safety index calculating section 215. [

The integrated safety index calculating section 215 may receive the static safety index, the dynamic safety index, and the workload safety index from the safety index calculating section 214. [ For example, in the same manner as in Equation (2), the comprehensive safety index calculating section 215 can calculate the total safety index. Equation (2) is one embodiment for calculating the total safety index. Therefore, the method for calculating the total safety index of the present invention is not limited to the following expression (2). Comprehensive safety indices can be calculated by combining static safety indices, dynamic safety indices, and workload safety indices in various ways.

In this way, the safety index calculation system 210 can calculate the comprehensive safety index using past accident record data and vehicle information data of each of the vehicles 100_1 to 100_q. The safety index calculation system 210 may provide at least one of the static safety index, the dynamic safety index, the workload safety index, and the comprehensive safety index to the drivers of the vehicles 100_1 to 100_q and the vehicles 100_1 to 100_q . Drivers who have been granted a high overall safety index may be more likely to cause accidents. Therefore, the drivers of the vehicles 100_1 to 100_q can refer to the static safety index, the dynamic safety index, the workload safety index, and the comprehensive safety index, and can reduce the accident rate.

The safety index calculation system 210 may store the calculated static safety index, dynamic safety index, workload safety index, and comprehensive safety index in the safety index database 220. [ The driver database 230 may include information on drivers of the vehicles 100_1 to 100_q, respectively.

The safety index calculation system 210 can output the safety index information. The safety index information may include at least one of a static safety index, a dynamic safety index, a workload safety index, and an integrated safety index. The safety index calculation system 210 may output safety index information together with driver information of the driver database 230. [ The safety index calculation system 210 can periodically output the safety index information and output it by an external request.

The safety index calculation system 210 may provide the safety index information to the driver and / or the manager of each of the vehicles 100_1 to 100_q. Illustratively, the safety index calculation system 210 can transmit safety index information to at least one of the PDA, navigation, and GPS receiver of each of the vehicles 100_1 to 100_q. In addition, the safety index calculation system 210 can transmit safety index information to smartphones of drivers who operate the vehicles 100_1 to 100_q, and wearable devices such as a smart clock.
