According to the revision issue of the end of the year of the Ministry of Public Security 2015《Motor vehicle driving license is claimed and uses regulation》(hereinafter referred to as《Newly
Hand over rule》) by the unlawful practice seriousness of driver according to《It is new to hand over rule》Correction formula, I is carried out to A classes data (real time data)
B classes data are carried out the serious sex determination of II class by the serious sex determination of class.Different unlawful practices have corresponding severity score.Tool
It is as follows that the evaluation index data of body list form in：
1st, II liang of serious sex determination of class data
The class evaluation index of table 1 I
| Unlawful practice | Seriousness X |
| Real-time violation data n | an |
| Real-time violation data n-1 | an-1 |
| …… | …… |
| Real-time violation data 3 | a3 |
| Real-time violation data 2 | a2 |
| Real-time violation data 1 | a1 |
The seriousness S of I class evaluation indexes1=an, seriousness is the positive correlation function of n.
The class evaluation index of table 2 II
| Unlawful practice | Seriousness Y |
| History records n in violation of rules and regulations | bn |
| History records n-1 in violation of rules and regulations | bn-1 |
| …… | …… |
| History records 3 in violation of rules and regulations | b3 |
| History records 2 in violation of rules and regulations | b2 |
| History records 1 in violation of rules and regulations | b1 |

2nd, safe class judges computing
The fraction (raw score) in each assessment indicator is calculated, I, II liang of data of class evaluation index is calculated using not
Same computing formula, specific implementation step is as follows：
1) driver's assessment process 1 --- the safety scoring based on I class data
I class data are the real time data of drive recorder record, by collecting into data operation module after data acquisition,
Concrete operation process is as follows：
The reaction time determines in violation situation：
Wherein：Xi is commercial drivers reaction time index score under violation situation；
M is the unlawful practice end time；
N is the unlawful practice time started；
U takes the time (it was found that in violation of rules and regulations and terminate time of the behavior) of the behavior for commercial drivers, and output function is：
If commercial drivers are in violation of rules and regulations, the judgement of violation reaction time is scored at A, if driver is without unlawful practice, this
Judgement is scored at 0.
I class evaluation index driver safety score is calculated：
In I class evaluation index, driver safety score may be used to minor function and represent：
T1=f (ai,Xi)
That is in I class evaluation index, commercial drivers safety is the function of three above variable, thus can calculate survey
Commercial drivers safety in process 1 is commented, computing formula is as follows：
Wherein：aiRepresent driver's unlawful practice severity level；
XiRepresent driver's reaction time index score under violation situation；
Then as described above, then commercial drivers safety T1Derivation can be calculated
2) driver's assessment process 2 --- the safety scoring based on II class data
II class data refer to each item data that shipping company can inspect periodically and record driver, and can carry out fortune every time
The state and each item data of record goods are improved before defeated business.Inspect periodically and be stored in history number because such data belongs to company
According to the data in storehouse, so there is the difference of the real time data of two and drive recorder record：I.e. data have passed through treatment and number
According to time effects factor.
Historical data is shorter away from the modern time, then the severity level of the unlawful practice of commercial drivers is higher, i.e., away from the present
The time weighting at nearer violation time point is higher, and some are the particular content of time adjustment：
Violation historical data is divided into Three Estate from time point：A, B, or C, occur away from existing depending on violation or traffic accident
Time, these three grades represent that unlawful practice is nearer away from modern time respectively, then its weight is higher, disobeying within 12 months
Rule behavior menace level highest, weight distribution is A, as follows by that analogy：
The time weighting table of table 7
| Time | Weight |
| Less than 12 months | A |
| - 24 months 12 months | B |
| - 36 months 24 months | C |
Upper frequency limit：If being counted into multiple same unlawful practices in once checking, only one unlawful practice is driven
Sail people's security evaluation system to be used, by above description, note time weighting is ti.
Because the source of historical data is the regular sampling observation of shipping company, therefore sampling observation number of times is considered to be surveyed in commercial drivers
Comment in process 2, sampling observation number of times is designated as λ.
Then in II class data, commercial drivers test and appraisal are comprised the following steps that：
In order to preferably compare the secure registration fraction of commercial drivers and other drivers in system, operation need to be calculated and driven
The violation time percentage of the person of sailing.Commercial drivers history violation data is extracted, asks its violation number of times to be driven with operation in system
The ratio of the average violation number of times of member：
δi=ki/α
Wherein：α is the average violation number of times of system；
kiIt is i-th bit commercial drivers violation number of times；
N is commercial drivers sum in system；
δiIt is i-th bit commercial drivers violation time percentage；
II class evaluation index driver safety score is calculated：
In II class evaluation index, driver safety score may be used to minor function and represent：
T2=f (ti,bi,δi,λ)
That is in I class evaluation index, commercial drivers safety is the function of three above variable, thus can calculate survey
Commercial drivers safety in process 1 is commented, computing formula is as follows：
Wherein：tiRepresent the time weighting of II class data；
biRepresent driver's unlawful practice severity level；
δiIt is i-th bit commercial drivers violation time percentage；
λ represents selective examination number of times；
Then as described above, then commercial drivers safety T2Derivation can be calculated.
3rd, display module
Human pilot grade (final score) in systems is calculated on the basis of raw score, to show driver's
Safety records location in colleague.Grading display process steps are as follows：
Calculate the gross score of single driver.Formula is as follows：
T=T1+T2, wherein：
T1--- the commercial drivers based on I class data score safely；
T2--- the commercial drivers based on II class data score safely；
Final score is carried out to round treatment, T is made*=Int (T), draws driver safety score.
The score of all drivers is arranged by ascending order from low to high, the ranking R of each driver is drawn.Score is minimum
Driver R=1, driver's ranking R=n of highest scoring；
Percentage P=(R -1)/n is calculated according to ranking.Wherein R is the ranking of driver, and n is total driver's number.P anticipates
Driver of the behavior expression than percentage P that taste the driver is poor.
Example is demonstrated
Collect the real time data such as table 10 of the driver.
The driver history tables of data of table 10
Treatment historical data.
Due to u ≠ 0, thereforeMade a phone call this behavior, m=12 during for driving:14:20, u=12:13:
45, n=12:13:23,
Driver's score=aiXi=0.614 × 5=3.07
Other data are processed as above, by such as table 11. of result after real time data processing
The driver of table 11 items Score Lists
Then T1=3.07+1.37+0.19=4.63
Collect driver history data such as table 13.
The driver history tables of data of table 12
Driver safety fraction measure and ranking are carried out for convenience, it is as shown in the table now by time weighting assignment：
Time weighting table after the assignment of table 13
| Time | Weight |
| Less than 12 months | 3 |
| - 24 months 12 months | 2 |
| - 36 months 24 months | 1 |
Treatment historical data, draws every score and total score of the driver.
For this unlawful practice of driver's injury, due to average violation number of times α=1.2, the violation number of times of the driver
k1=2, therefore driver's violation time percentage
And severity score b1=3, time weighting t1=3
Other data are processed as above, after historical data is processed as shown in table 14.
The driver of table 14 items Score Lists
Then T2=15+15+5+60+7.74+2.58+1.2+3.85=110.37
Show that the driver is scored at：T=T1+T2=115, T*=Int (T)=115
Driver's grading is carried out by above-mentioned PTS：
The fraction of all drivers in computing system.
All fractions are arranged by ascending order from low to high.The driver is located at the 2461st, i.e. R=2461.
Calculate percentage P=(the 2461-1)/10000=24.6% of the driver, the i.e. driver driving than 24.6%
The person's of sailing performance is poor.
