It is standby in real time to monitor driver and whether have a behavior of using terminal equipment, and driver be how using terminal equipment
, be conducive to determining whether the danger of driver's usage behavior, can more precisely analyze the traffic safety of driver.
First operation can be the arbitrary operation that driver is carried out to terminal device, for example, it may be lighting screen
The operation operate, made a phone call, the operation for sending short message, etc..
If terminal device determines that driver has carried out the first operation for terminal device by real-time monitoring state, can be with
Determine the type of the first operation, that is, determine which kind of operation the first operation is actually.For determining the first type for operating
Mode, the embodiment of the present disclosure is not construed as limiting.For example, the state for listening to short message broadcast and note data storehouse determines the first operation
Operation for transmission short message, etc..
Because driver is when vehicle is driven, the behavior of terminal device is operated to influence the security driven a vehicle, more dispersion note
The influence of the operation behavior to travel safety of power of anticipating is bigger, therefore, in the embodiment of the present disclosure, can be it is determined that first operation
After type, the type according to the first operation determines the security reliability of driver's driving behavior.Security reliability can be used to comment
Valency driver currently drives the security of vehicle, and security reliability is higher, and the security that driver drives vehicle is also higher.It is right
In it is determined that the mode of the security reliability of driver's driving behavior, the embodiment of the present disclosure is not construed as limiting, below to several possible
Mode is illustrated.
Optionally, the first operation can be determined according to the corresponding relation between the type of operation and operational hazards grade
The corresponding operational hazards grade of type, further according to the corresponding operational hazards grade of type of the first operation, determines that driver drives
The security reliability of behavior, wherein, operational hazards grade higher, and the security reliability of driving is lower.
That is, to the division of operations of terminal device can be different by driver according to the difference of action type
Operational hazards grade, operational hazards grade can reflect that the operation influences the degree size of driving safety, operational hazards grade to get over
Height, carries out the operation more dangerous during driving.Each action type can have corresponding operational hazards grade, for example, hand-held
The operational hazards grade for receiving calls is λ1, the non-hand-held operational hazards grade for receiving calls is λ2, it is hand-held in startup procedure
Receive calls compared to it is non-it is hand-held receive calls it is more dangerous, then λ1>λ2, etc..
After the first operation that driver carries out is determined, operational hazards grade that can be corresponding according to the first operation come
Determine security reliability.For how to determine security reliability according to the operational hazards grade of the first operation, the disclosure is implemented
Example is not construed as limiting.For example, operational hazards grade can be with security reliability in inverse proportion function relation, exponential function relation, right
Number functional relation or linear functional relation, etc., as long as security reliability is reduced i.e. with the rising of operational hazards grade
Can.By such mode, in startup procedure, carrying out more dangerous operation will cause that security reliability is lower to driver, because
This, security reliability can relatively accurately react the security that driver drives vehicle.
Optionally, according to the corresponding operational hazards grade of type of the first operation, the safety of driver's driving behavior is determined
Reliability, can be according to reliability function R (t)=e-λt, the security reliability of driver's driving behavior is calculated, wherein, R is peace
Full reliability, 0≤R≤1, λ is operational hazards grade, λ>0, t is the lasting duration of operation, t ＞ 0.
The security reliability of using terminal equipment can endanger with the operation of driver's operation terminal device when driving
Dangerous increasing for grade and reduce, security reliability analysis meet reliability theory, reliability function R (t)=e can be based on-λtEnter
Row analysis, t is more long for operation duration, and security reliability R is smaller, the coefficient of operational hazards grade λ i.e. function, for
For the function of monotone decreasing, coefficient is bigger, and curve downward trend is faster, therefore, in the case where t is constant, operational hazards
Grade λ is bigger, and security reliability R is smaller.By driver for the corresponding operational hazards of the first operation that terminal device is carried out
Grade, such as be λ1, and the lasting duration of the first operation, such as it is t1, substitute into above formula, just can obtain driver and drive
Sail the security reliability R of behavior1.So, quantitatively the security that driver drives can be analyzed, as a result more may be used
By, it is accurate.
Optionally, the flow chart of traffic safety analysis method shown in Figure 2, can also include step S14：Obtain
Travel speed of the vehicle when the first operation is carried out, then step S13 can be：Type and traveling speed according to the first operation
Degree, determines the security reliability of driver's driving behavior.
Obtain travel speed, can by the GPS that is arranged in terminal device (Global Positioning System,
Global positioning system) module is obtained, or also can be obtained also by other modes, the embodiment of the present disclosure is not construed as limiting to this.
Because in actual applications, often speed is faster, driver gets over needs and concentrates on driving, therefore driver sets in using terminal
Speed when standby is faster, and security is lower.The type and travel speed of the first operation carried out according to driver are common come really
Determine the security reliability of driver's driving behavior, more accurate result can be obtained, be conducive to preferably assessment driver to drive
Sail the security of vehicle.
Optionally, the first operation can be determined according to the corresponding relation between the type of operation and operational hazards grade
The corresponding operational hazards grade of type；And, according to the corresponding relation between travel speed and traveling danger classes, determine that vehicle exists
The corresponding traveling danger classes of travel speed when first operation is carried out, then can be according to the corresponding behaviour of type of the first operation
Make the corresponding traveling danger classes of travel speed of danger classes and vehicle when the first operation is carried out, determine that driver drives
The security reliability of behavior, wherein, operational hazards grade is bigger with the product of traveling danger classes, and the security reliability of driving is got over
It is low.
According to the difference of travel speed, different travel speeds can be divided into different traveling danger classes, travelled
Speed is faster, and traveling danger classes is higher, therefore, under equal conditions (such as driver carries out same operation), traveling danger
Dangerous grade higher, and the security of driving is just lower.
That is, when the security reliability of driver's driving behavior is calculated, can comprehensive driver to terminal device
The drive speed when type and driver for being operated are operated obtains security reliability jointly, then can be based on driving
Operational hazards grade corresponding to the operation that the person of sailing is carried out is bigger with the product of the traveling danger classes corresponding to travel speed, OK

The security reliability of using terminal equipment can endanger with the operation of driver's operation terminal device when driving
Dangerous grade increases and travels increasing for danger classes and reduce.Reliability function R (t)=e can be so based on-kλtCarry out
Analysis, after introducing traveling danger classes k on the basis of original, equivalent to increased risk factor, k >=1, as k=1,
It is considered that not influenceed on original function, work as k>When 1, it is believed that reduce reliability on the basis of original.For example,
Can set when travel speed is interior positioned at interval [0,40], corresponding traveling danger classes k=1, when travel speed is located at area
Between (40,60] it is interior when, corresponding traveling danger classes k=1.2, when travel speed be located at it is interval (60,80] it is interior when, corresponding row
Danger classes k=1.5 is sailed, when travel speed is interior positioned at interval (80, ∞), corresponding traveling danger classes k=2, etc..
Likewise, being based on reliability function R (t)=e-kλt, t is more long for operation duration, and security reliability R is smaller,
The product of operational hazards grade λ and traveling danger classes k, that is, function coefficient, for the function of monotone decreasing, be
Number is bigger, and curve downward trend is faster, therefore, in the case where t is constant, operational hazards grade λ is with traveling danger classes k's
Product is bigger, and security reliability R is smaller.For example, by driver for the corresponding operation of the first operation that terminal device is carried out
Danger classes, such as be λ1, driver carry out the corresponding traveling danger classes of travel speed that the first operation is vehicle, such as
k1And the first lasting duration of operation, such as it is t1, substitute into above formula, just can obtain the safety of driver's driving behavior

Can be according to reliability function R (t)=α e-λt, the security reliability of driver's driving behavior is calculated, wherein, α is turning
Risk factor,T1It is the duration for completing to turn, T2It is the lasting duration of first operation, R during turning
It is security reliability, 0≤R≤1, λ is operational hazards grade, λ>0, t is the lasting duration of operation, t ＞ 0.
That is, in above-mentioned reliability function R (t)=e-λtOn the basis of introduce turning risk factor α, while based on operation
Danger classes λ and turning risk factor α calculates security reliability.T1It is the duration for completing to turn, that is, starts to turn
Experienced duration, T are completed to turning2Be the lasting duration of first operation during turning, that is, turn when
Between section and the first operation the duration that overlaps of time period.Time of the driver using mobile phone during turning is more long, driving
Security is just lower,So for adding reliability function R (the t)=α e of turning risk factor-λtFor, α
Value it is bigger, security reliability is just higher.
Certainly, calculate security reliability when can also consider simultaneously turning risk factor α, operational hazards grade λ and
Sail danger classes k three, then in this case, reliability function is R (t)=α e-kλt。
By that with upper type, can determine the security reliability of vehicle traveling with reference to many factors, as a result more reliable,
Accurately.
