Below in conjunction with accompanying drawing, with specific embodiment, method provided by the invention and traffic events system are described in detail.
Embodiment 1:
Be the disposal route of a kind of traffic events that the embodiment of the present invention 1 provides as shown in Figure 2, specifically comprise the steps:
The traffic events that S201, reception report.
In this step, the traffic events reported can be the traffic events that user is reported by map software, navigation software or the social platform etc. that terminal is installed.
Further, can receive by the access service of traffic events system the traffic events reported.
Whether there is the traffic events received with this to belong to the traffic events of the same reporting of user of same information source in the credible traffic events in the issue term of validity that S202, judgement have reported, if had, then enter step S203, otherwise, enter step S205.
Whether S203, the distance of effective time whether between the overlapping and traffic events position of carrying judging these two traffic events are less than default distance threshold, if be all, then enter step S204, if effective time is not overlapping and/or distance between position is greater than default distance threshold, then enter step S205.
Further, in step S202 ~ step S203, first pre-service can be carried out to the traffic events received, comprise: remove the traffic events repeating to report, that is, when existing in the credible traffic events in the issue term of validity reported and this traffic events received belongs to the traffic events of same reporting of user of same information source, can judge further these two traffic events, judge whether these two traffic events meet following two conditions: condition one: whether the effective time of these two traffic events is overlapping simultaneously; Condition two: whether the distance between the position that these two traffic events carry is less than default distance threshold, if meet this two conditions, then determine that these two traffic events are traffic events that the same user of same information source repeats to report, the traffic events that this receives can be abandoned; If do not meet one of them condition or two conditions all do not meet, then determine that these two traffic events are different traffic events of the same reporting of user of same information source, this two traffic events can be retained, continue follow-up process.
S204, abandon this traffic events.This flow process terminates.
Further, because the credibility of the traffic events obtained by multiple channel is different, in order to ensure accuracy and the validity of the final traffic events issued, need to judge the confidence level of traffic events.Step S205 ~ step S213 is the step of the confidence level determining the traffic events received, specifically can be as follows:
S205, judge that whether the event end time that carries of traffic events received is early than current time, if so, then enters step S204, otherwise, enter step S206.
Further, in this step, can judge according to the confidence level of the event end time carried in traffic events to reported traffic events:
When the event end time carried in traffic events is before current time, can determines that reported traffic events is expired, traffic events is abandoned.
Further, start time and the end time of reported traffic events is not carried in the traffic events received, or the start time of carrying and the end time unreasonable time (such as, start time is identical with the end time), according to the default duration of the traffic events corresponding with this traffic events type preset, the start time of reported traffic events and end time can be carried out arranging or revising.
S206, judge that success obtains the event type of traffic events, if can, enter step S207, otherwise, enter step S204.
Further, in step S205 ~ step S206, judge that whether the event end time that carries of traffic events received is early than current time, if, then abandon this traffic events, if not, then obtain the event type of traffic events, if obtained less than event type, then abandon this traffic events, in step S205 ~ step S206, also the event type of the traffic events of reception can first be obtained, if obtained less than event type, then abandon this traffic events, otherwise, judge that whether the event end time that carries of traffic events received is early than current time, if, then abandon this traffic events, if not, then continue subsequent step.
Further, if the event end time carried in traffic events is later than current time, can also obtain further the event type of traffic events, the event type of traffic events can comprise: flow type event (such as: walk or drive slowly, block up, heavy congestion etc.), traffic hazard (such as: general traffic hazard, severe traffic accidents etc.), construction event, control event, weather effect etc.
Further, the event type of traffic events can be obtained in the following way:
The event type that traffic events carries is obtained from the event type field of traffic events, if event type field is empty, then the event content of traffic events is mated with preset event type key table, obtain the event type of event type corresponding to key word as traffic events of coupling;
Further, preset keyword can for the key word relevant to traffic events type pre-set, such as: block up, block, traffic hazard, construction, (traffic | road) & control etc.Such as, the information content of the traffic events received comprises the text description of " Renminnan Road blocks up ", this text description and preset event type key word are compared, determine that the information content of the traffic events received " is blocked up " with preset event type key word to mate, can determine that the type of this traffic events is flow type event.If obtained by the way less than event type, then can abandon this traffic events.
Whether the event type that S207, judgement get is flow type, if so, then enters step S208, otherwise, enter step S210.
S208, judge that success obtains the traffic events speed of carrying, if can, then enter step S209, otherwise, enter step S204.
S209, judge whether speed that traffic events carries falls into velocity range corresponding to traffic flow modes that traffic events carries, if so, then enters step S210, otherwise, enter step S204.
Further, in step S208 ~ step S209, obtain the speed that traffic events carries, if obtained less than speed, then abandon this traffic events, otherwise, judge whether speed that traffic events carries falls into velocity range corresponding to traffic flow modes that traffic events carries, if not, then abandons this traffic events, if so, then step S210 is entered.
Further, when the type determining traffic events is flow type, and carry velocity information in traffic events, can the confidence level of velocity range to this traffic events corresponding to the traffic flow modes that carries of Negotiation speed information and traffic events judge further:
When the speed that traffic events carries does not fall into velocity range corresponding to traffic flow modes that traffic events carries, such as, the traffic events that the person of reporting reports is that Renminnan Road blocks up, and the speed of carrying be 60 step, suppose that the velocity range that congestion status is corresponding steps for being less than 20, the speed that the traffic events then not reporting person to report carries does not fall into velocity range corresponding to congestion status, can determine that reported traffic events is insincere traffic events, be abandoned by this traffic events.
S210, judge whether event content that traffic events carries comprises the word in default sensitive word vocabulary, if comprised, then enters step S204, otherwise, enter step S211.
Further, sensitive word vocabulary can be pre-set, such as: the word not allowing to deliver specified in laws and regulations, statutory regulation do not allow the word etc. occurred on the internet.
S211, according to the information source of traffic events received, from the information source preset with the corresponding relation of confidence level, the confidence level that the information source of acquisition traffic events is corresponding.
Further, in this step, different information sources can have different confidence levels, the reliable information source that can pre-set, such as: special messenger's typing (namely special messenger is according to reliable traffic events message, by traffic events typing traffic events system), this source credibility is higher, preferably, the traffic events from reliable information source directly can be defined as credible traffic events.
Preferably, confidence value can be set for often kind of information source, as the initial trusted angle value of the traffic events from this information source.In follow-up deterministic process, the basis of this initial trusted angle value increases and decreases, obtain the confidence value of this final traffic events.
S212, judge whether carry multimedia messages in traffic events, if carried, then increase the confidence level of traffic events, enter step S213, if do not carried, then enter step S213.
Further, can according to the confidence level of the quantity of the multimedia messages for describing reported traffic events carried in traffic events and/or quality determination traffic events.That is, if carry multimedia messages in traffic events, illustrate that this traffic events sophistication is better, and according to the corresponding relation between the information sophistication preset and confidence level, the confidence level of reported traffic events is judged further.Such as: the information sophistication that the traffic events reported can be weighed by the mode of counting, when comprise in the information content first quantity with preset quality for describing the multimedia file of traffic events time, the information sophistication of the traffic events that this can be reported increases the first quantity digit.Wherein, preset quality can be the readability of multimedia file.Further, according to the corresponding relation between the information sophistication preset and confidence level, the confidence level of this traffic events reported is determined.
Illustrate below: what comprise in the information content of the first traffic events received is 3 width pictures clearly for describing the multimedia file of reported traffic events, the information sophistication of this first traffic events received can be defined as 3 digits, and the multimedia file for describing reported traffic events do not comprised in the information content of the second traffic events received, the information sophistication of this information can be defined as 0 digit, suppose that the corresponding relation between default information sophistication and confidence level is: use the count value of information sophistication to represent confidence level, can determine that the confidence level of the traffic events of the first reception is 3, the confidence level of the second traffic events received is 0.
S213, the text carried by traffic events describe and mate with the antistop list preset, if matched, then increase the confidence level of traffic events, otherwise, keep the confidence level of traffic events constant.
Further, the text that can carry traffic events in traffic events describes, text describes more accurate more in detail, illustrate that the confidence level of this traffic events reported is higher, therefore, the text that traffic events can be carried describes and mates, if matched with the antistop list (such as characterizing the keyword of traffic events type: block up) preset, then increase the confidence level of traffic events, the amplitude of increase can set according to actual needs.
Further, the execution of step S210 ~ step S213 does not have strict sequencing.
If S214 confidence level is greater than default believability threshold, then this traffic events is defined as credible traffic events.
Preferably, confidence level initial value can be set for the traffic events received, described confidence level initial value is corresponding with the information source of this traffic events, confidence level initial value corresponding to more believable information source is higher, and pass through above-mentioned steps, the various information that traffic events carries are judged, correspondingly confidence value is increased and decreased according to judged result, the confidence value finally obtained and default believability threshold are compared, and when confidence level is greater than default believability threshold, this traffic events is defined as credible traffic events.
Further, if confidence level is not more than default believability threshold, then this traffic events can be defined as insincere traffic events, traffic events can be abandoned.
Further, step S215 ~ step S218 is from the credible traffic events in the issue term of validity reported, and determines that the credible traffic events received with this describes the step of the credible traffic events of same traffic events, specific as follows:
S215, judge if be flow type event, then to enter the event type of this credible traffic events received step S216, if be non-flow type event, then enter step S217.
S216, judge can from reported issuing the credible traffic events in the term of validity, determine that the credible traffic events received with this occurs in same link and has overlapping effective time and the credible traffic events of distance within the scope of preset distance of the position of carrying with the credible traffic events that this receives.If determined, then enter step S218, otherwise this flow process terminates.
Further, for the credible traffic events that type is flow type, such as: walk or drive slowly, block up, heavy congestion etc., can think that the coverage of this traffic events is the section at this traffic events place, therefore, can by there is identical road information and have overlapping traffic events effective time and the credible traffic events of distance within the scope of preset distance of the position of carrying with the credible traffic events that this receives is defined as same traffic events.
Can S217, judgement from the credible traffic events in the issue term of validity reported, determine that the credible traffic events received with this has overlapping effective time and occurs in the credible traffic events in same link.If determined, then enter step S218, otherwise this flow process terminates.
Further, for the credible traffic events that type is non-flow type, such as: construction, control etc., can think that the coverage of this traffic events is relevant with the character of event itself, therefore, overlapping effective time will can be had with the credible traffic events that this receives and the credible traffic events occurred in same link is defined as same traffic events.
Further, in step S216 ~ step S217, what reported can comprise and being polymerized and the father's event issued, the credible traffic events etc. that reports issuing the credible traffic events in the term of validity, even if these events are issued, as long as but in the issue term of validity, just can continue for carrying out with the same credible traffic events just received being polymerized and continuing to issue, until stale event.Like this, jointly determine to form the credible traffic events of same traffic events by the credible traffic events not yet issued and the traffic events issued, what avoid traffic events repeats issue, causes information redundancy.
Further, if all do not determine corresponding credible traffic events in S216 and S217, then determine in the credible traffic events in the issue term of validity reported, there is not the traffic events that the credible traffic events received with this describes same traffic events, subsequent treatment can be carried out to the credible traffic events that this receives after this traffic events treatment scheme terminates, such as, this traffic events received be distributed to application terminal or specify platform etc.
Further, step S218 ~ step S221 be by this credible traffic events received and from reported issuing the credible traffic events determined the credible traffic events in the term of validity and be polymerized to the step of a credible traffic events, and the execution of step S218 ~ step S221 does not have strict sequencing, specific as follows:
S218, by this credible traffic events received and from reported issuing in the credible traffic events determined the credible traffic events in the term of validity, the positional information that the credible traffic events that confidence level is the highest carries, is defined as the positional information of the traffic events after being polymerized.
S219, the initial time of being carried by credible traffic events the highest for confidence level and termination time, be defined as initial time and the termination time of the traffic events after being polymerized.
S220, the text descriptor of being carried by credible traffic events the highest for confidence level, be defined as the text descriptor of the traffic events after being polymerized.
Further, describe if credible traffic events does not comprise text, credible traffic events mates with road by the positional information of then carrying according to credible traffic events, if can match on road, the road then mated according to credible traffic events and the event type of credible traffic events, the text generating this credible traffic events describes, if can not match on road, then carry out the event type of location information and the credible traffic events obtained against geocoding according to the positional information of carrying credible traffic events, the text generating this credible traffic events describes.
S221, evaluate superposition by this credible traffic events received with from what reported at the multimedia file and user of issuing the credible traffic events determined the credible traffic events in the term of validity, the multimedia file after superposition and user are evaluated the multimedia file being defined as the traffic events after being polymerized and user evaluates.This flow process terminates.
Further, the traffic events of the issue reported, when again issuing, can have user to evaluate and confidence level, usually not have user to evaluate for the event newly reported itself.
Further, subevent can be defined as by the credible traffic events of this reception with from the credible traffic events in the issue term of validity reported, be polymerized by the credible traffic events received by this with from the credible traffic events in the issue term of validity reported father's event that the credible traffic events obtained is defined as subevent.
During concrete enforcement, it can be the traffic events allocation identification (ID) of each reception, so, a new traffic part can be defined as by being polymerized the traffic events obtained, i.e. father's traffic events, and distribute ID, the traffic events of repetition corresponding for this father's traffic events is defined as sub-traffic events.Illustrate below:
Example 1: suppose that user A reports traffic events, content comprises: the Jing Mi south of road, 2013-11-2910:00 ~ 11:00 Beijing is north to the text description of blocking up, user B reports traffic events, content comprises: the text description of Jing Milu direction, 2013-11-2910:10 ~ 11:30 Beijing blocking, and for the picture that describes this traffic events and audio file, determine that the first traffic events that user A reports and the second traffic events that user B reports are credible traffic events, again because the first traffic events and the second traffic events are flow type event, the position of carrying in the content of the traffic events reported according to user A and user B, determine that the first traffic events that user A reports and the second traffic events that user B reports occur in same link, determine that distance between the position that the first traffic events carries and the position that the second traffic events carries is within the scope of preset distance further, again because the first traffic events and the second traffic events have overlapping effective time, determine that the first traffic events and the second traffic events describe same traffic events,
Further, the with a high credibility in the first traffic events of the second traffic events is determined.Converging operation is performed to the first traffic events and the second traffic events, generate the 3rd traffic events, the content of the 3rd traffic events can comprise text description corresponding to the second traffic events, the i.e. text description of Jing Milu direction, 2013-11-2910:10 ~ 11:30 Beijing blocking, comprise the position that the second traffic events carries, comprise traffic events 10:10 ~ 11:30 effective time that the second traffic events is corresponding, and the multimedia file that second carries in traffic events, so, first traffic events and the second traffic events can be defined as the subevent of the 3rd traffic events, 3rd traffic events is father's event of the first traffic events and the second traffic events.
Further, subsequent treatment can be carried out after this traffic events treatment scheme terminates, traffic events after polymerization be distributed to application terminal or specify platform, for this application terminal or specify platform to be user on the map of specifying application to show this credible traffic events, and calculate flow information or the congestion of road according to credible traffic events when navigation path planning, be the more time saving guidance path of user's planning.
Further, father's traffic events can be issued, also father's traffic events and sub-traffic events all can be distributed to application terminal or specify platform, that is, when user sees father's traffic events of this issue, the multiple sub-traffic events aggregating into this father's traffic events can be seen simultaneously.
Further, when generating new father's traffic events for announced traffic events and the traffic events not yet issued, and when father's traffic events is issued, by the original event of issuing traffic from application terminal or specify platform to delete.
Owing to have employed this programme, making can be automatically merged accurately and rapidly by the traffic events of different channel reception, and fast sharing gives other users.And by traffic events being distributed to traffic flow integrated service and online navigation Service, the effect that traffic events affects traffic flow modes, affects navigation programming route can be realized.Meanwhile, validity and the coverage of event can be dynamically updated by traffic flow
Further, the traffic events of issue is changing as time goes by, can upgrade announced traffic events.Such as, when traffic events solves, traffic events and expired, renewal rewards theory needs the traffic events of Delete Expired from the traffic events issued; When the person of reporting has reported the new multimedia file of certain traffic events, renewal rewards theory needs the multimedia file of this traffic events to upgrade; When the comment (such as step on, praise) for certain traffic events have updated, renewal rewards theory needs to upgrade the comment content of this traffic events; When the state updating of certain traffic events, renewal rewards theory needs the duration etc. upgrading this traffic events.Therefore, in this step, budget rules can be formulated according to actual needs, the relevant information of institute's Communities concerned with traffic event is upgraded.
Based on same inventive concept, the embodiment of the present invention additionally provides a kind of traffic events system, the principle of dealing with problems due to these systems is similar to the disposal route of aforementioned a kind of traffic events, and therefore the enforcement of this system see the enforcement of preceding method, can repeat part and repeat no more.
