Currently sample details data include：It is the operating range of current road segment corresponding with current bicycle speed sample, current The actual travel time in section, the mark of current road segment and running section flag bit, running section flag bit are that characterization is current Section whether be just travelled into new section mark.Wherein, the new section in the embodiment of the present invention refers to current bicycle herein Section when driving into another section from previous section in secondary stroke.

Therefore, in embodiments of the present invention, terminal can be according to current bicycle speed sample and current sample details data To carry out validity, repeatability and the setting of priority.

Wherein, terminal is according to current line match information, current acquisition time information, historical route match information and history Acquisition time information obtains the operating range of current road segment corresponding with current bicycle speed sample and the practical row of current road segment Sail the time.

It should be noted that in embodiments of the present invention, terminal can pass through history acquisition time information and historical route Match information, at the time of obtaining current bicycle and enter current road segment；Then, terminal can also according to current line match information, Current bicycle is obtained in the operating range of current road segment；Finally, terminal passes through again by current acquisition time information and current bicycle It is made the difference at the time of into current road segment, obtains the actual travel time of the corresponding current road segment of current bicycle speed sample.

Further, terminal realizes the process of S1041, i.e., the process that terminal assesses current bicycle speed sample availability can To include：It is preset based on running section flag bit, the operating range of current road segment, the actual travel time of current road segment, first Free flow journey time and the second default free flow journey time, assess current bicycle speed sample availability.

Specifically, such as S201-S210.It is as follows：

S201, it is based on running section flag bit, judges whether current bicycle enters new section.

After obtaining current sample details data due to terminal, which has just had learned that working as where current bicycle The mark in preceding section, the current bicycle more specific location information and running section flag bit on section in this prior, and the end End is being the historical sample detail data of the available bicycle before, and in this case, which can be according to traveling road Segment mark position and history running section flag bit, judge whether current bicycle enters new section.

Specifically, the stroke of running section flag bit can be：Due to including history in historical route match information The specific location of the mark in section and the bicycle on history section, in this way, terminal can be by judging history section It identifies whether to identify whether unanimously with current road segment come obtain current bicycle be all to enter determined for new section, when When consistent, the flag bit characterization of running section does not enter new section, and when there is inconsistency, the flag bit characterization of running section enters new Section；Alternatively, terminal can gone through by comparing more specific location information and the bicycle of the current bicycle in this prior on section Specific location on history section carries out the judgement whether current bicycle enters new section, and then the number of traveling flag bit is arranged Value.

Optionally, in embodiments of the present invention, when traveling flag bit is 1, characterization current road segment is new section；Traveling mark When position is 0, the section current section Bu Weixin is characterized.The setting embodiment of the present invention of traveling flag bit is with no restriction, reasonable.

It should be noted that historical route match information can acquire current bicycle for terminal in the embodiment of the present invention The corresponding historical route match information of the same bicycle acquired recently before location information.

In embodiments of the present invention, terminal is by judging whether current bicycle enters new section to select terminal be desirable Which kind of validity rule to carry out the assessment of bicycle speed sample availability, the default validity that the embodiment of the present invention proposes by Rule includes：Default first validity rule and default second validity rule.

In embodiments of the present invention, when the case where current bicycle does not enter new section, presetting the first validity rule can be with For it is following any one：

The operating range of current road segment is more than or equal to default first percentage of current road segment total length；

The actual travel time of current road segment is greater than the first default free flow journey time, and the operating range of current road segment More than or equal to default second percentage of current road segment total length.Wherein, the first high percentage is preset in default second percentage.

In embodiments of the present invention, when the case where current bicycle has entered new section, presetting the second validity rule can be with For it is following any one：

The operating range of preceding a road section is more than or equal to the default third percentage of preceding a road section total length；

The actual travel time of preceding a road section is greater than the second default free flow journey time, and the operating range of preceding a road section More than or equal to default 4th percentage of preceding a road section total length.Wherein, it presets third percentage and is greater than the default 4th well-behaved ratio.

Illustratively, it is assumed that current bicycle is vehicle, and the default validity rule in the embodiment of the present invention can be following Any one：

(1) vehicle not yet covers current road segment, and overlay length (operating range of current road segment) is more than current road segment overall length The 70% of degree.

(2) vehicle not yet covers current road segment, and the traveled distance time (actual travel time of current road segment) alreadys exceed Free flow journey time, and overlay length is more than the 50% of road section length.

(3) vehicle has covered current road segment, and overlay length is more than the 50% of road section length.

(4) vehicle has covered current road segment, and the traveled distance time alreadys exceed free flow journey time, and overlay length More than the 30% of current road segment total length.

Wherein, overlay length refers to the distance that vehicle travels on current road segment.The traveled distance time, refer to by current Moment, the time span that vehicle has travelled on current road segment.Free flow journey time refers to when without other vehicle shadows It rings, is only limited down (under i.e. ideal road driving conditions) by current road segment real road condition, the complete current road segment of vehicle driving The time span of required consuming.This is a fixed attribute of current road segment, unrelated with the behavior of vehicle.

It should be noted that accuracy of the embodiment of the present invention based on the considerations of efficiency assessment, setting the default 100th Divide ratio, default second percentage, default third percentage and default 4th percentage.Basic setting principle can be：More When dimension carries out the assessment of validity, the operating range of current road segment be more than the preset percentage of current road segment total length be can be with Operating range than only passing through current road segment carries out the corresponding factor of efficiency assessment and percentage is low, i.e., default second percentage Than presetting the 4th percentage and being lower than default third percentage etc. lower than default first percentage.

S202, when running section flag bit characterization current road segment be not new section when, if the operating range of current road segment is big In default first percentage for being equal to current road segment total length, then current bicycle sample is effective.

S203, when running section flag bit characterization current road segment be not new section when, if the operating range of current road segment is small In default first percentage of current road segment total length, then current bicycle sample is invalid.

Terminal is based on traveling flag bit, after judging whether current bicycle enters new section, if the terminal is judged to work as Preceding bicycle does not enter new section, and characterization terminal acquisition is that can use about the corresponding current bicycle speed sample of current bicycle , then at this moment, which can operating range based on the corresponding current road segment of current bicycle speed sample and current road The actual travel time of section carries out the efficiency assessment of next step.

Specifically, judging the operating range of current road segment, the actual travel time of current road segment and the first default free flow Whether journey time meets default first validity rule, and default first validity rule is for there is current bicycle sample The first of effect property assessment determines that the first default free flow journey time has travelled under conditions of only being limited by road for characterization to be worked as Time spent by preceding section.

Reality of the terminal in the operating range and current road segment for obtaining current road segment corresponding with current bicycle speed sample After running time, which can obtain the first default validity rule, to judge the operating range, current of current road segment Whether the actual travel time in section and the first default free flow journey time meet default first validity rule, wherein pre- If the first validity rule is used to carry out current bicycle sample the first of efficiency assessment to determine.

It should be noted that the first default free flow journey time in the embodiment of the present invention is only limited by road for characterizing The time spent by current road segment is travelled under conditions of system, this first default free flow journey time is that terminal is got The time travelled under conditions of only being limited by road on current road segment.

Specifically, and if the operating range of current road segment is more than or equal to default first percentage of current road segment total length, Terminal then characterizes default first validity rule of satisfaction, and current bicycle sample is effective.Alternatively, if the operating range of current road segment is small In default first percentage of current road segment total length, terminal, which then characterizes, is unsatisfactory for default first validity rule, current bicycle Sample is invalid.

Terminal is default freely popular in the actual travel time for the operating range, current road segment for judging current road segment and first After whether the journey time meets default first validity rule, when the operating range that default first validity rule is current road segment More than or equal to current road segment total length when presetting the first percentage, terminal judges whether that the operating range for meeting current road segment is big In default first percentage for being equal to current road segment total length；If the operating range of current road segment is more than or equal to current road segment overall length Default first percentage of degree then characterizes default first validity rule of satisfaction；If the operating range of current road segment is less than current Default first percentage of section total length, then characterization is unsatisfactory for default first validity rule.It is effective when meeting default first Property rule, then current bicycle speed sample is effective；When being unsatisfactory for default first validity rule, then current bicycle speed sample without Effect.

S204, when running section flag bit characterization current road segment be not new section when, if when the actual travel of current road segment Between be greater than the first default free flow journey time, and the operating range of current road segment is more than or equal to the default of current road segment total length Second percentage, then current bicycle sample is effective, wherein default second percentage is less than default first percentage.

S205, when running section flag bit characterization current road segment be not new section when, if when the actual travel of current road segment Between be less than or equal to the first default free flow journey time, and the operating range of current road segment is less than the default of current road segment total length Second percentage, then current bicycle sample is invalid.

Terminal is default freely popular in the actual travel time for the operating range, current road segment for judging current road segment and first After whether the journey time meets default first validity rule, when the actual travel that default first validity rule is current road segment Time is greater than the first default free flow journey time, and the operating range of current road segment is more than or equal to the pre- of current road segment total length If when the second percentage, when terminal judges whether that the actual travel time for meeting current road segment is greater than the first default free flow stroke Between, and the operating range of current road segment is more than or equal to default second percentage of current road segment total length；If the reality of current road segment Border running time is greater than the first default free flow journey time, and the operating range of current road segment is more than or equal to current road segment overall length Default second percentage of degree then characterizes default first validity rule of satisfaction；If the actual travel time when current road segment is small In being equal to the first default free flow journey time, and the operating range of current road segment is more than or equal to the default of current road segment total length Second percentage, then characterization is unsatisfactory for default first validity rule.The first validity rule is preset when meeting, then current bicycle Speed sample is effective；When being unsatisfactory for default first validity rule, then current bicycle speed sample is invalid.

S206, when running section flag bit characterization current road segment is new section, it is corresponding to obtain current bicycle speed sample Preceding a road section operating range and preceding a road section actual travel time.

It should be noted that historical route match information can acquire current bicycle for terminal in the embodiment of the present invention The corresponding historical route match information of the same bicycle acquired recently before location information.

In embodiments of the present invention, if terminal judges that current bicycle has entered new section, the current bicycle has been characterized just Driven into a new section, at this point, terminal can by default second validity rule to current bicycle speed sample into The assessment of row validity rule.And the speed sample of bicycle next time for the current bicycle that terminal acquires next time is still on the new road It is travelled in section, at that time, terminal can still carry out bicycle speed sample next time by default first validity rule effective The assessment of property.

Therefore, after terminal judges whether current bicycle enters new section, if current bicycle has entered new section, terminal It can then be believed according to current line match information, current acquisition time information, historical route match information and history acquisition time Breath obtains the operating range of preceding a road section corresponding with current bicycle speed sample and the actual travel time of preceding a road section.

It should be noted that in embodiments of the present invention, terminal can pass through history acquisition time information and historical route Match information and current line match information, obtain preceding a road section of current solo running, and obtain current bicycle enter it is previous At the time of section, current bicycle enter preceding a road section traveling-position information and current bicycle be driven out to before a road section position letter Breath；Then, the location information and current bicycle of a road section enter the traveling-position of preceding a road section before current bicycle is driven out to by terminal Information makes the difference, and obtains the operating range of the corresponding preceding a road section of current bicycle speed sample；Finally, terminal is again by will currently adopt Collection temporal information makes the difference at the time of entering preceding a road section with current bicycle, obtains the corresponding preceding a road section of current bicycle speed sample Actual travel time.

If the operating range of S207, preceding a road section is more than or equal to the default third percentage of preceding a road section total length, when Preceding bicycle sample is effective.

If the operating range of S208, preceding a road section is less than the default third percentage of preceding a road section total length, current single Vehicle sample is invalid.

Reality of the terminal in the operating range and preceding a road section for obtaining preceding a road section corresponding with current bicycle speed sample After running time, which can obtain the second default validity rule, with the operating range, previous of a road section before judging Whether the actual travel time in section and the second default free flow journey time meet default second validity rule, wherein pre- If the second validity rule is used to carry out current bicycle sample the second of efficiency assessment to determine.

It should be noted that the second default free flow journey time in the embodiment of the present invention is for characterizing ideal road travel permit Part downlink finishes the time spent by previous section, this second default free flow journey time be terminal get previous The time travelled under conditions of only being limited by road on section.

In embodiments of the present invention, terminal before judgement the operating range of a road section, preceding a road section actual travel time After whether meeting default second validity rule with the second default free flow journey time, the operating range of current a road section is big When being equal to the default third percentage of preceding a road section total length, terminal judges whether that the operating range of a road section before meeting is greater than Equal to the default third percentage of preceding a road section total length；If the operating range of preceding a road section is more than or equal to preceding a road section total length Default third percentage, then characterize default second validity rule of satisfaction；If the operating range of preceding a road section be less than it is preceding all the way The default third percentage of section total length, then characterization is unsatisfactory for default second validity rule.The second validity is preset when meeting Rule, then current bicycle speed sample is effective；When being unsatisfactory for default second validity rule, then current bicycle speed sample without Effect.

If the actual travel time of S209, preceding a road section is greater than the second default free flow journey time, and preceding a road section Operating range is more than or equal to default 4th percentage of preceding a road section total length, then current bicycle sample is effective, wherein default the Four percentages are less than default third percentage.

If the actual travel time of S210, preceding a road section be less than or equal to the second default free flow journey time, and it is preceding all the way The operating range of section is less than default 4th percentage of preceding a road section total length, then current bicycle sample is invalid.

The terminal operating range of a road section, the actual travel time of preceding a road section and second before judgement is default freely popular After whether the journey time meets default second validity rule, it is default free that the actual travel time of current a road section is greater than second Journey time is flowed, and the operating range of preceding a road section is more than or equal to when presetting four percentage of preceding a road section total length, terminal Judge whether that the actual travel time of a road section before meeting is greater than the second default free flow journey time, and the traveling of preceding a road section Distance is more than or equal to default 4th percentage of preceding a road section total length；If it is pre- that the actual travel time of preceding a road section is greater than second If free flow journey time, and the operating range of preceding a road section is more than or equal to default 4th percentage of preceding a road section total length, Then characterize default second validity rule of satisfaction；If it is default freely popular that the actual travel time of preceding a road section is less than or equal to second The journey time, and the operating range of preceding a road section is more than or equal to default 4th percentage of preceding a road section total length, then characterization is discontented Default second validity rule of foot.When meeting default second validity rule, then current bicycle speed sample is effective；When being unsatisfactory for Default second validity rule, then current bicycle speed sample is invalid.

It is understood that terminal can be discarded pair by carrying out the assessment of validity to current bicycle speed sample Lesser sample is contributed in the judgement of the congestion of current road segment, and such processing improves the bicycle speed of terminal to server transmission The validity of the data of sample is spent, and also reduces transmitted data amount between terminal and server, and then service can be mitigated The calculating pressure of device section.

Further, the setting principle of the default repeatability rule in the embodiment of the present invention is by current bicycle speed sample It is compared with the preceding bicycle speed sample once returned, to judge that current bicycle speed sample once returns in front of being Bicycle speed sample be it is duplicate, can abandon.If current bicycle speed sample is for the preceding bicycle speed sample once returned It for this, does not provide and updates more valuable data or information, then the current bicycle speed sample is It is not necessary to return to Server.

It should be noted that default repeatability rule may include it is following any one：

(1), current bicycle speed sample is different from the preceding corresponding section of bicycle speed sample once returned.

(2), current bicycle speed sample is identical as the preceding corresponding section of bicycle speed sample once returned, but respectively right The jam level answered is different.

(3), current bicycle speed sample is identical as the preceding section of bicycle speed sample once returned, corresponding to gather around Stifled grade is identical, and corresponding speed values differ by more than pre-set velocity threshold value.

(4), the corresponding current acquisition time information of current bicycle speed sample and the preceding bicycle speed sample once returned Passback time information differs by more than preset time threshold.

In embodiments of the present invention, terminal is carried out according to process, that is, terminal that default repeatability rule carries out repeated processing S1042 when terminal is for effective current bicycle speed sample, judges according to (1), (2) and (3) in default repeatability rule Whether current bicycle speed sample is to repeat the process of bicycle speed sample to may include：S301-S302.It is as follows：

If S301, current bicycle speed sample are effective, the corresponding preceding a road section of previous bicycle speed sample is obtained Mark, previous history jam level and previous bicycle speed, previous bicycle speed sample be current bicycle sample it The preceding nearest bicycle speed sample for successfully returning to server.

It should be noted that terminal is based on carrying out under the premise of current bicycle speed sample is effective in embodiments of the present invention The judgement of repeated rule, in this way, when terminal carries out the judgement of repeatability of current bicycle speed sample, due to pre- If repeated rule is all based on the judgement carried out between current bicycle speed sample and the preceding bicycle speed sample once returned, Therefore, terminal needs first to obtain the corresponding previous bicycle speed of previous bicycle speed sample and previous historical sample Detail data, previous bicycle speed sample here are server is successfully returned to before current bicycle sample nearest Bicycle speed sample (the bicycle speed sample once returned before i.e.).

In embodiments of the present invention, terminal can be from the mark for obtaining preceding a road section in historic details sample data with before One history jam level.

Specifically, according to the mark of the current road segment in current line match information and previous historical route match information In preceding a road section mark, judge that the corresponding current road segment of current bicycle speed sample and previous bicycle speed sample are corresponding Previous section whether be identical section.

After terminal obtains the corresponding previous historical sample detail data of previous bicycle speed sample, due to previous It may include the mark in the corresponding previous section of previous bicycle speed sample, therefore, terminal in historical sample detail data It is the section that can be known previous bicycle speed sample and travel, in embodiments of the present invention, by previous bicycle The section that speed sample is travelling is known as previous section；Meanwhile terminal is that can obtain by current sample details data Know the mark for the current road segment that current bicycle speed sample is travelling.Finally, terminal can pass through previous section Mark the corresponding current road segment of current bicycle speed sample and previous bicycle speed are judged with the mark of current road segment Whether the corresponding previous section of sample is identical section.Wherein, no matter current bicycle speed sample or previous bicycle For the bicycle that speed sample is arranged both for terminal, that is to say, that current bicycle speed sample and previous bicycle speed It is the same bicycle for spending sample both for the corresponding current bicycle of transformation terminal.

It should be noted that limiting terminal does not judge the corresponding current road segment of current bicycle speed sample to the embodiment of the present invention Previous section corresponding with previous bicycle speed sample whether be identical section implementation, all reasonable realizations , the embodiment of the present invention is with no restriction.

Illustratively, car-mounted terminal knows that current automobile is being travelled this moment in section 1 according to current sample details data On, car-mounted terminal knows current automobile according to the corresponding previous bicycle historical sample detail data of previous bicycle speed sample It is being travelled on section 2 in previous bicycle speed sample, such car-mounted terminal can be sentenced by section 1 and section 2 It is disconnected go out the current corresponding current road segment of bicycle speed sample and the corresponding previous section of previous bicycle speed sample whether be Identical section.

S302, the mark based on current road segment, current bicycle speed, the mark in previous section, previous history congestion Grade, previous bicycle speed and pre-set velocity threshold value, assess the repeatability of current bicycle speed sample.

Terminal judges that current bicycle speed is corresponding with the mark in previous section according to the mark for judging current road segment and works as Whether preceding section and the corresponding previous section of previous bicycle speed sample are identical section.When for same road segment, eventually End gets cur-rent congestion grade further according to current bicycle speed, according to the current jam level and previous history jam level Carry out determine repeatability, when cur-rent congestion grade is identical with previous history jam level, terminal according to current bicycle speed, Previous bicycle speed and pre-set velocity threshold value finally carry out the judgement or assessment of repeatability.

Specifically, the specific implementation of S302 can be：S3021-S3026.It is as follows：

S3021, when current road segment mark it is different from the mark in previous section when, characterizing current bicycle speed sample is Non-duplicate bicycle speed sample.

S3022, when current road segment mark it is identical with the mark in previous section when, by current bicycle speed with preset gather around Stifled hierarchical speed section is compared, and obtains the corresponding cur-rent congestion grade of current bicycle speed sample, and obtain previous list The corresponding previous history jam level of vehicle speed sample.

Terminal judges the corresponding current road segment of current bicycle speed and the corresponding previous road of previous bicycle speed sample After whether section is identical section, the result of terminal judgement can there are two types of, Yi Zhongwei：Current road segment and previous section For different sections；Another kind is：Current road segment and previous section are identical section.So, current road segment with it is previous A section be different sections when, terminal can affirm that current bicycle speed sample is meaningful, not with previous list Vehicle speed sample repeats；If but when current road segment and previous section are identical section, terminal will then be carried out into one The judgement of the repeatability of step.At this moment, terminal can be using the jam level in section to determine whether this current bicycle speed Whether sample has processing meaning.In this case, terminal is when judging current road segment and previous section is identical section, With regard to needing to carry out calculating for the current corresponding cur-rent congestion grade of bicycle speed sample.

Specifically, due to current bicycle speed sample embody be a travel speed numerical value, then terminal is can be with The corresponding current bicycle speed of current bicycle speed sample is obtained, then current bicycle speed sample and default congestion are classified Speed interval is compared, so that it may know which default congestion hierarchical speed section is current bicycle speed can fall in, from And the corresponding cur-rent congestion grade of current bicycle speed sample is obtained.Then, a terminal bicycle speed sample before treatment When, the corresponding previous jam level of previous bicycle speed sample has also been obtained, in this way, terminal can be by current Bicycle jam level and previous bicycle jam level carry out the judgement of further repeatability.

It should be noted that in embodiments of the present invention, default congestion hierarchical speed section, which corresponds to each section, to be had, And default congestion hierarchical speed section is that the server road that can characterize that bicycle speed sample statistics come out based on the received is gathered around The speed class section of stifled situation.Terminal can be got from server in advance.

Optionally, the corresponding relationship library that congestion hierarchical speed section can be jam level and speed interval is preset.For example, Jam level in the embodiment of the present invention can be divided into：Unimpeded, jogging and congestion three grades, but above-mentioned three can also be directed to Kind jam situation carries out the division of refinement levels again, that is to say, that as long as the division rule of jam level and standard are rationally, The embodiment of the present invention and with no restriction.

It illustratively, is as shown in table 1 the corresponding relationship library of jam level and speed interval.Wherein, speed interval is When 50km/h-70km/h, jam level is unimpeded；When speed interval is 20km/h-50km/h, jam level is jogging；Speed When section is 10km/h-20km/h, jam level is congestion.

Table 1

Jam level	Speed interval (km/h)
		It is unimpeded	50-70
Jogging	20-50
		Congestion	10-20

S3023, when the jam level difference of cur-rent congestion grade and previous history jam level, characterize current bicycle Speed sample is non-duplicate bicycle speed sample.

After terminal obtains current bicycle jam level and previous bicycle jam level, which just passes through currently Bicycle jam level and previous bicycle jam level carry out the judgement of further repeatability, which can be worked as by judgement Whether preceding jam level identical as the jam level of previous history jam level, come judge current bicycle speed sample with it is previous Whether a bicycle speed sample repeats.

It is in embodiment in the present invention, terminal may determine that the congestion of cur-rent congestion grade Yu previous history jam level Whether grade is identical, when the jam level difference of cur-rent congestion grade and previous history jam level, characterizes current bicycle speed Degree sample embodies the situation of change of present road situation, and such current bicycle speed sample is to have to the variation of real-time road Meaning and contribution, therefore, terminal judge that current bicycle speed sample in such cases is non-duplicate bicycle speed sample This.And cur-rent congestion grade it is identical as the jam level of previous history jam level when, characterize current bicycle speed sample body The case where having showed present road situation and previous bicycle speed sample are constant in terms of being embodied in congestion, then, it is such Currently whether bicycle speed sample is helpful to the variation of real-time road further to be sentenced by other features again Disconnected, at this moment, terminal can further be judged by the current bicycle speed and previous bicycle speed of acquisition.

S3024, when cur-rent congestion grade is identical as the jam level of previous history jam level, according to current bicycle Speed, the speed of previous bicycle speed and pre-set velocity threshold value carry out repeated assessment.

If the speed difference of S3025, current bicycle speed and previous bicycle speed are more than or equal to pre-set velocity threshold value, Current bicycle speed sample is non-duplicate bicycle speed sample.

If the speed difference of S3026, current bicycle speed and previous bicycle speed are less than pre-set velocity threshold value, currently Bicycle speed sample is to repeat bicycle speed sample.

Terminal obtain current bicycle speed sample current bicycle speed and previous bicycle speed sample it is corresponding previous After a bicycle speed, terminal feelings identical with the jam level of previous history jam level for cur-rent congestion grade Condition, the further judgement that repeatability is carried out by bicycle speed.

In embodiments of the present invention, terminal passes through the list for judging current bicycle speed sample Yu previous bicycle speed sample Vehicle speed difference carries out the judgement of repeatability, i.e. terminal judges that the speed difference of current bicycle speed and previous bicycle speed is It is no to be more than or equal to pre-set velocity threshold value, if speed difference is more than or equal to pre-set velocity threshold value, current bicycle is characterized in jam level In the case where the same, the variation in travel speed has embodied the larger difference with previous bicycle speed sample, explanation Jam level may be changed, in this case, current bicycle speed sample to the variation of real-time road be it is significant and Contribution, therefore, it is non-duplicate bicycle speed sample that terminal, which judges current bicycle speed sample,；Conversely, if speed difference is small In pre-set velocity threshold value, characterize current bicycle in the case where jam level is the same, the variation in travel speed embodied with The difference of the very little of previous bicycle speed sample illustrates that jam level may be current single still without being changed, in this case Vehicle speed sample is little to the contribution of the variation of real-time road, and then, terminal determines current bicycle speed sample to repeat bicycle Speed sample.

Optionally, the pre-set velocity threshold value in the embodiment of the present invention can be 10km/h, and actual pre-set velocity threshold value is It is determined by actual travel and road conditions, the embodiment of the present invention is with no restriction.

Further, in embodiments of the present invention, terminal carries out the process of repeated processing according to default repeatability rule Except S301-S302, terminal carries out the process terminal of repeated processing for effective current according to default repeatability rule When bicycle speed sample, judge whether current bicycle speed sample is to repeat bicycle speed according to (4) in default repeatability rule Degree sample process can also include：S303-S304.It is as follows：

If S303, current bicycle speed sample are effective, the corresponding previous history of previous bicycle speed sample is obtained Time information is returned, previous history passback time information is for successfully returning to server before being characterized in current bicycle sample Nearest bicycle speed sample turn around time.

S304, worked as based on current acquisition time information, previous history passback time information and preset time threshold, assessment The repeatability of preceding bicycle speed sample.

It should be noted that terminal is based on carrying out under the premise of current bicycle speed sample is effective in embodiments of the present invention The judgement of repeated rule, in this way, when terminal carries out the judgement of repeatability of current bicycle speed sample, due to pre- If repeated rule is all based on the judgement carried out between current bicycle speed sample and the preceding bicycle speed sample once returned, Terminal can pass through the time of the turn around time of previous bicycle speed sample and the acquisition of current bicycle speed sample in this way The time interval of time carries out the judgement of bicycle speed sample repeatability.At this moment, terminal needs first to obtain previous bicycle The corresponding previous history of speed sample returns time information, and previous bicycle speed sample here is in current bicycle sample The nearest bicycle speed sample (the bicycle speed sample once returned before i.e.) of server is successfully returned to before, it is previous to go through History passback time information is used to before being characterized in current bicycle sample successfully return to the nearest bicycle speed sample of server Turn around time.Then, terminal can make the difference current acquisition time information and previous history passback time information, to carry out The repeatability judgement of bicycle speed sample.

Specifically, the specific implementation of S304 may include：S3041-S3042.It is as follows：

If the time difference of S3041, current acquisition time information and previous history passback time information are more than or equal to pre- If time threshold, then current bicycle speed sample is non-duplicate bicycle speed sample.

If the time difference of S3042, current acquisition time information and previous history passback time information are less than default Between threshold value, then current bicycle speed sample be repeat bicycle speed sample.

After terminal obtains the corresponding previous history passback time information of previous bicycle speed sample, which can To make the difference current acquisition time information and previous history passback time information, the time difference is obtained, to carry out bicycle speed sample This repeatability judgement.

In embodiments of the present invention, terminal passes through the list for judging current bicycle speed sample Yu previous bicycle speed sample Vehicle speed difference carries out the judgement of repeatability, i.e. terminal judges that current acquisition time information and previous history return time information Time difference whether be more than or equal to preset time threshold, if time difference is more than or equal to preset time threshold, characterize current single It has been spaced a longer time between vehicle speed sample and the previous bicycle speed sample of last passback, then In such a longer time, the case where link change, may have occurred that change, in this case, current bicycle speed sample This is significant and contribution to the variation of real-time road, and therefore, it is non-duplicate list that terminal, which judges current bicycle speed sample, Vehicle speed sample；Conversely, characterizing current bicycle speed sample and last passback if time difference is less than preset time threshold Interval time is very short between previous bicycle speed sample, then within such a shorter time, link change The case where may be still big for the probability that change, in this case, variation of the current bicycle speed sample to real-time road Contribution it is little, then, terminal determines that current bicycle speed sample is to repeat bicycle speed sample.

Optionally, the preset time threshold in the embodiment of the present invention can be 1 minute, actual preset time threshold be by What actual travel and road conditions determined, the embodiment of the present invention is with no restriction.

It should be noted that terminal is when carrying out the repetition sex determination of S301-S304 description, terminal is being judged to work as When preceding bicycle speed sample is repeated sample, such current production of the bicycle speed sample for real-time road data is characterized Be do not have it is helpful, at this point, terminal by the current bicycle speed sample to being discarded, without subsequent priority level initializing and current The processing of bicycle speed sample passback.And if terminal judges that current bicycle speed sample is non-repeatability sample, characterization Such current bicycle speed sample is helpful the production of real-time road data, at this point, terminal is by the current bicycle Speed sample carries out the processing of subsequent priority level initializing and the passback of current bicycle speed sample.

It is understood that terminal can be discarded pair by carrying out the assessment of repeatability to current bicycle speed sample Duplicate sample is contributed in the judgement of the congestion of current road segment, and such processing improves the bicycle speed of terminal to server transmission The validity for spending the data of sample is avoided the repetition transmission of the sample of significant contribution, is reduced between terminal and server with this Transmitted data amount, and then the processing data of server section can be mitigated and calculate the pressure of data.

Further, in embodiments of the present invention, terminal carries out the setting of priority to the current bicycle speed sample Process, i.e. terminal for current bicycle speed sample be non-duplicate bicycle speed sample when, to current bicycle speed sample carry out The setting of priority, meeting passback conditioning process with characterization may include：S401-S402.It is as follows：

If S401, current bicycle speed sample are non-duplicate bicycle speed sample, the current bicycle speed sample is obtained This corresponding cur-rent congestion grade, and take the jam level of the current road segment where announced current bicycle speed sample.

S402, rule is set to current list according to cur-rent congestion grade, the jam level of current road segment and pre-set priority Vehicle speed sample sets priority parameters, obtains the current bicycle speed sample set.

Due to current bicycle speed sample embody be a travel speed numerical value, then terminal is available current The corresponding current bicycle speed of bicycle speed sample, then by current bicycle speed sample and default congestion hierarchical speed section It is compared, so that it may know which default congestion hierarchical speed section is current bicycle speed can fall in, to obtain The corresponding cur-rent congestion grade of current bicycle speed sample in current bicycle speed sample is non-duplicate bicycle speed sample in terminal This when, terminal can be directly obtained cur-rent congestion grade.Then, terminal can also go to get from server current The jam level of the current road segment for the current road segment that current bicycle is travelled in the issued real-time road of server, in this way, Terminal can set rule to current bicycle speed according to cur-rent congestion grade, the jam level of current road segment and pre-set priority It spends sample and sets priority parameters, retrieve the current bicycle speed sample provided with priority and (set the current speed of object for appreciation Spend sample).Then, the current bicycle speed sample for being provided with priority can be returned to server by terminal, to carry out reality When road condition data processing.

In embodiments of the present invention, pre-set priority setting rule includes：

(1), cur-rent congestion grade and when the jam level difference of current road segment the setting of cur-rent congestion grade current preference Grade, higher than the cur-rent congestion grade current priority that cur-rent congestion grade is set when identical as the jam level of current road segment；

(2), when cur-rent congestion grade is different from the jam level of current road segment, and the jam level characterization of current road segment When the non-congestion of road conditions, the road conditions of cur-rent congestion grade characterization are poorer, and the current priority of cur-rent congestion grade setting is higher；

(3), when cur-rent congestion grade is different from the jam level of current road segment, and the jam level characterization of current road segment When road conditions congestion, the rank difference between cur-rent congestion grade and the jam level of current road segment is bigger, the setting of cur-rent congestion grade Current priority it is higher；

(4), when cur-rent congestion grade is identical as the jam level of current road segment, the road conditions of cur-rent congestion grade characterization are gathered around The current priority set when stifled is higher than the current priority set when non-congestion.

Illustratively, in embodiments of the present invention, integer numerical identity priority can be used, the higher characterization of numerical value is preferential Grade is higher, in this way, priority quantizing rule, that is, pre-set priority rule can be as shown in table 2.Here, include with jam level： It is illustrated for unimpeded, jogging and congestion.

Table 2

From Table 2, it can be seen that firstly, cur-rent congestion grade can be when the jam level of current road segment is unimpeded Unimpeded, jogging and three kinds of grades of congestion, cur-rent congestion when being the jam level difference with current road segment for cur-rent congestion grade Cur-rent congestion grade is set when the current priority of grade setting is identical as the jam level of current road segment higher than cur-rent congestion grade Fixed current priority, then, numerical priority value 6 in the first row in table 2 (when cur-rent congestion grade is jogging) or 8 (when When preceding jam level is congestion) it is above numerical priority value 1, wherein and 6 and 8 corresponding cur-rent congestion grades are to be different from working as The jam level in preceding section, 1 corresponding cur-rent congestion grade is the same as the jam level of current road segment.Likewise, table 2 In the second row and the setting of the numerical priority value in the third line and the rule of the first row it is consistent.

Secondly, when cur-rent congestion grade and the jam level difference of current road segment, for example, the cur-rent congestion etc. in the second row It is different from the jogging of the jam level of current road segment when grade is congestion or is unimpeded, and at this moment, the jam level of current road segment characterizes Jogging the case where being non-congestion, in this case, the road conditions of cur-rent congestion grade characterization are poorer, and cur-rent congestion grade is set Fixed current priority is higher, and therefore, the road conditions of the congestion of cur-rent congestion grade characterization are worse than the smooth of cur-rent congestion grade characterization Therefore cur-rent congestion grade is also the bicycle speed sample of congestion in the case where meeting preset rules (1) by logical road conditions Priority be set as 7, set 3 for priority that cur-rent congestion grade is smooth bicycle speed sample.

Then, cur-rent congestion grade and when the jam level difference of current road segment, for example, the cur-rent congestion etc. in the third line It is different from the jam level congestion of current road segment when grade is walks or drive slowly or is unimpeded, and at this moment, the jam level of current road segment characterizes Congestion the case where being congestion, in this case, the grade between cur-rent congestion grade and the jam level of current road segment Difference is bigger, and the current priority of cur-rent congestion grade setting is higher, therefore, cur-rent congestion grade characterization it is unimpeded when, and it is current When the jam level in section is the jogging that the rank difference between congestion is 2, and cur-rent congestion grade characterizes, with gathering around for current road segment Stifled grade is that the rank difference between congestion is 1,2 greater than 1, therefore, in the case where meeting preset rules (1), will also currently be gathered around That blocks up the priority that grade is smooth bicycle speed sample is set as 5, is the bicycle speed sample of jogging by cur-rent congestion grade This priority is set as 4.

Finally, when cur-rent congestion grade is identical as the jam level of current road segment, the road conditions of cur-rent congestion grade characterization The current priority that the sets when current priority set when congestion is higher than non-congestion, then, in table 2, cur-rent congestion grade with When the jam level of current road segment is all unimpeded, or all for jogging when, the priority of bicycle speed sample is both configured to 1, and When cur-rent congestion grade and the jam level of current road segment are all congestion, the priority of bicycle speed sample is both configured to 2, and 2 is high In 1.At this moment because in bicycle speed sample, the importance of the sample for contributing to road conditions congestion is higher than other congestions The sample of grade.

It is understood that in embodiments of the present invention, using the processing for carrying out priority level initializing to bicycle speed sample, Allow opposite end server will be by priority processing, to guarantee as far as possible most to the bicycle speed sample for possessing higher priority Important road condition change information, preferentially can be published out, so that real-time road condition information obtains the processing that timely updates, from And improve the timeliness of real-time road data.

It should be noted that in embodiments of the present invention, pre-set priority rule, default repeatability is regular and is preset with Effect property rule is provided to preferably filter out more useful bicycle speed sample, as long as this big principle is constant, then in advance The set-up mode embodiment of the present invention of setting priority rule, default repeatability rule and default validity rule can not limit System.

In embodiments of the present invention, terminal for validity and repeatability judgement can optionally at least one, this Inventive embodiments can be with no restriction.Preferably, terminal carries out validity, repeatability and priority to current bicycle speed sample Setting.
