Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Embodiments of the invention provide a kind of disposal route of road traffic accident information, as shown in Figure 1, comprise the following steps:
S11 obtains the mass parameter of described road traffic accident information;
S12 obtains corresponding certain threshold level according to preseting;
S13, contrast described mass parameter and certain threshold level, according to the result of described contrast, determine whether the quality index of described road traffic accident information is qualified, described quality index comprises at least a in information prompt, information correctness, information integrity and the collection stability.
The disposal route that the embodiment of the invention provides is judged by each quality index to comparing the road traffic accident information that gathers of mass parameter and certain threshold level, can obtain the quality condition of the interior road traffic accident information that gathers of regular period.The quality condition that obtains can provide for follow-up information acquisition the improvement reference, improves the quality of the real-time traffic event information that gathers, and brings into play greatly the positive role of road traffic accident information.
Because being distributed to the user's of intelligent transportation system road traffic accident information should be in time also complete, and want accurately, therefore, the disposal route that the embodiment of the invention provides, the quality index that can determine comprises the information prompt of the road traffic accident information that gathers, information correctness, information integrity, collection stability at least a, the four kinds of quality index of acquired information simultaneously, also one or more quality index can be obtained, the quality index of needs acquisition can be selected according to actual requirement.Certainly, corresponding to different quality index, the mass parameter of obtaining in the S11 step and the certain threshold level of obtaining in the S12 step are different.
Usually, at intelligent transportation field, road traffic accident can be divided quality scale according to road grade, event type and the duration etc. of scene, the road traffic accident of different quality grade is because the factor that relates to is different, desired information quality may be different, therefore, the S12 step can be divided into for two steps and carry out, at first determine the quality scale of described road traffic accident information, then, obtain the certain threshold level corresponding with described quality scale according to preseting, each quality scale is different corresponding to the certain threshold level of each quality index.
The quality scale that adopts in the embodiment of the invention is the road grade according to the road traffic accident scene, event type and lasting cycle (event begins to finish institute's elapsed time to event) divide, road traffic accident is divided into three quality grades of A/B/C, wherein, road grade comprises intercity super expressway RTIC1, high in the city, expressway RTIC2, major urban arterial highway RCITC3 and other roads RTIC4 level Four, event type comprises traffic control, traffic time, construction operation and road barricade, the lasting cycle comprises long period, middle cycle and end cycle.Wherein, corresponding to different road grades and event type, continue the dividing mode in cycle as shown in Table 1, the dividing mode that quality grade is concrete in the embodiment of the invention as shown in Table 2.
Table one: (h: hour, m: minute, d: day)
In the S12 step, if comprise the quality grade of this road traffic accident information in the road traffic accident information, so just can find or obtain by modes such as calculating according to setting in advance the certain threshold level of corresponding this quality index of this quality grade.Certainly, if do not comprise the quality grade of this road traffic accident information in the road traffic accident information, also can be according to the event type that comprises in the information, location of incident and duration etc., according to predefined grade classification mode, determine the quality grade of described road traffic accident information, then according to quality grade, obtain the certain threshold level of corresponding this quality index of this quality grade.
Certainly, adoptable quality scale is not limit the mode shown in the table two in the embodiment of the invention, can be according to the actual conditions setting, and the disposal route that the embodiment of the invention provides is equally applicable to different quality scale mode classifications.
Table two:
Further, the disposal route that provides of the embodiment of the invention also comprises the oeverall quality index qualified step whether of determining other described road traffic accident information of equal in quality level.Through S11 to S13 step, quality condition that can the unit's of acquisition road traffic accident information, afterwards, the Qualification of the quality index that can also obtain according to S11 to S13 step determines whether the oeverall quality index of described road traffic accident information is qualified.Specifically can adopt following manner: the ratio that obtains the total number of the qualified information number of other road traffic accident information quality index of equal in quality level and other road traffic accident information of equal in quality level, it is qualification rate, the qualification rate threshold that described qualification rate is corresponding with this quality scale, when described qualification rate during more than or equal to described qualification rate threshold value, determine the oeverall quality qualified of the road traffic accident information of this quality scale.
