Road conditions result.
For 606 steps in above scheme, only one length is more than charge station within the scope of charge station's road at this time
The section section of road range needs to use the hourage in the section section and calculating in database for the judgement of its road condition
Slow hourage threshold range of gathering around out is compared and can just be obtained, illustratively, specific embodiment one referring to shown in Fig. 4,
Include:
701, from the category for obtaining the single section section of outbound road or inbound road within the scope of charge station's road in database
Property data, the attribute data include save section length, position etc..
702, judge to charge according to lookup result after the road condition data in the database lookup section section according to attribute data
Whether the single section section stood within the scope of road has corresponding road condition data in the database.
If the single section section within the scope of charge station's road executes 703 in the database without corresponding road condition data；If receiving
There is corresponding road condition data in single section section within the scope of the road of expense station in the database, executes 704.
703, determine that the section section be road condition is unimpeded.
Specifically, this processing result is mainly to set in systems after investigating statistics according to practical situation.
704, judge whether the section section is that lower high speed sails out of charge station.

706, judge whether the section section is that lower high speed enters charge station.
If lower high speed enters charge station, 708 are executed；If not lower high speed enters charge station, 707 are executed.
707, judge whether the section section is that upper high speed enters charge station.
If upper high speed enters charge station, 708 are executed.
704 to 707 above-mentioned steps distinguish various vehicles by charge station's different situations, are primarily due to
Calculating needs to use vehicle driving average speed when gathering around slow hourage threshold range, and the vehicle row under these four different situations
It sails average speed to be different, so distinguishing.
708, according to length be more than charge station's road range section section length, preset vehicle traveling average speed and
The default waiting time that vehicle enters charge station gathers around slow threshold range calculating and gathers around slow hourage threshold range, and vehicle enters charge
The default waiting time threshold range stood is the queuing time range that vehicle enters charge station.
Wherein as the average speed of the preset vehicle traveling in the case of four kinds of 704 to 707 and vehicle enter charge station
The default waiting time gathers around slow threshold range and is different；Specific formula for calculation is as follows:
When hourage threshold values (unit: 0.1s)=section 1.0/ average speed of road section length * (unit: km/h) * 36+ is waited
Between (unit: 0.1s)
The relevant explanation of formula is as follows:
A, above-mentioned formula is equivalent to: vehicle is in charge station's used time=running time+queuing time, and wherein vehicle is in charge station
Used time and hourage threshold value be it is identical, queuing time is equal to the waiting time.
B, formula (section 1.0/ average speed of road section length *) part indicates, enters charge station in vehicle and uses without being lined up
Time.
C, formula (waiting time) part indicate, before have vehicle, the time for needing to be lined up.
D, variable average speed is determined according to statistics under historical data line.
E, the variable waiting time determines according to system designer subjectivity, illustratively, the processing of current toll gate road conditions
System enters charge station and gathers around slow threshold range [90s, 180s] waiting time, sails out of charge station and gathers around slow threshold range the waiting time
[20s, 40s].
709, basis gathers around slow hourage threshold range and the hourage of the section section in the database judges the section road
The case where road condition of section, wherein the hourage of the section section in the database is also to step 704 to 707, is related；Include:
When the length be more than charge station's road range section section in the database corresponding hourage be greater than gather around slow hourage threshold
Be worth range in maximum value when, determine length be more than charge station's road range section section road condition be it is unimpeded；When length is super
Cross the section section of charge station's road range in the database the value of corresponding hourage be located at and gather around slow hourage threshold range
When middle, the section section road condition for determining that length is more than charge station's road range is slow；When length is more than charge station's road model
Corresponding hourage is less than when gathering around minimum value in slow hourage threshold range in the database in the section section enclosed, and determines length
Degree is more than that the section section road condition of charge station's road range is congestion；Hourage is that vehicle passes through length more than charge station road
The time that the section section of road range needs.
710, the Vehicle Speed value of the section section in the database is modified according to obtained section section road condition.
This measure is primarily due in charge station's road conditions processing system provided in an embodiment of the present invention be existing road conditions
The improvement of a part of processing system or new addition part need one in each standard and existing road conditions processing system
It causes, and mainly determines each section section road condition by speed in the prior art, and in treatment process of the invention
As shown in table 2, the raw velocity interval threshold of original system is changed, also within the scope of charge station's road only one
Section section in the case where be road condition is determined according to hourage, so this need by road condition reconvert at
The comparison processing of total system after facilitating in the database is stored after the corresponding velocity amplitude of the identical road condition of original system.
The charge station's road conditions processing method provided in above-described embodiment one, gets charge station from database first
The attribute data in the single section section of road range inner outlet or entrance, is then looked into from database according to these attribute datas
Corresponding road condition data is looked for, classification processing is carried out according to lookup result, if not finding corresponding data, it is determined that the section section road
Condition state be it is unimpeded, if finding corresponding data according to the section section present position it is different calculate gather around slow travelling accordingly when
Between threshold range, then will gather around slow hourage threshold range and compared with the hourage in road condition data, so that it is determined that
The road condition in the section section, finally adjusting the velocity amplitude in road condition data according to road condition makes entire road conditions processing system number
It is consistent according to relationship.Charge station's road conditions processing method in the embodiment by charge station's road range inner outlet or
The different situations that person's entrance contains single section section carry out calculation processing to obtain more realistic more quasi- with different data
True road conditions.
Illustratively, for for the step 607 and step 608 mentioned above the case where, charge station's road model at this time
When outbound road or inbound road in enclosing include multiple section sections, specific embodiment two is referring to as shown in Figure 5, comprising:
801, from the attribute data in the multiple section sections obtained in database within the scope of charge station's road.
