Urban road is in continuous variation just, makes the database in our the GPS navigation system be faced with regular modification.The banning of turning movement traffic rules are important navigation datas, be recorded in and turn on the junction node, writing down in the sign description field of junction node junction node code ID, advance limit inLink, go out limit outLink, be illustrated on this junction node, can not redirect to out the limit from entering the limit; Referring to the Fig. 1 in the description of drawings, represented is on the crossing point of node ID=45546202418, can not redirect to the limit of LinkID=45546202502 from the limit of LinkID=45546201168.This shows, the recording method of this banning of turning movement rule and relevant sign code ID close association, this just requires in the navigation data in a zone, must all distribute unique relevant sign code ID for every section road with each road junction in advance, and the ID of every section road to remain in editing process from now on constant.Because in the navigation data production run, we can not determine to have what section roads in advance in the navigation data in a zone, more can't determine can increase or delete what section roads along with the development and change of this area road construction.When intersecting when one section new road of every increase and original section road intersect, can increase a new crossing point so on original section road, road originally also can be divided into two, newly-increased crossing point and two sections of being divided into two all need to redistribute the ID code; When one section road of deletion also similar problem can appear.Which kind of no matter under the situation, when the import or export ID of the banning of turning movement rule that is write down changes, all need this record is carried out edit-modify again.And this phenomenon meeting ubiquity in the navigation data production run, frequent modification banning of turning movement regular record is not only made mistakes easily, and has increased the workload of data edition, thereby has influence on quality and efficient that data are produced.
Summary of the invention
The input method that the purpose of this invention is to provide banning of turning movement sign in crossing in a kind of automated navigation system, use the banning of turning movement identification record of a certain junction node of this method generation, only relevant with the inlet highway section in the counterclockwise serial number of junction node target with authentication code, the junction node target authentication code in outlet highway section.
The concrete method that adopts of the present invention is to realize that by means of computor-keyboard said input method is finished by following steps under the support of GPS navigation software and electronic chart:
1. at a selected crossing that the road working direction is reached, 0-N flowing water numbering is carried out according to the order that is rotated counterclockwise in each road junction that links to each other with this crossing point, the flowing water sequence number of wherein selected road way outlet is made as 0, is followed successively by 1-N according to each import sequence number of counter clockwise direction;
2. a N bit be set be the limited code that turns to that enters behind this road along place, crossing that working direction reached, the figure place of this binary number is corresponding to the number of the flowing water at the target crossing that will change over to numbering, and the numerical value of the sign indicating number corresponding with target crossing numbering was 1 in this binary number when target crossing limit changed over to, not limit the numerical value of this yard position when changing over to be 0;
3. with above said N bit value as turning to the input of regular attribute codes, the banning of turning movement attribute setting of giving a nearest shape point at the crossing that is reached apart from this road working direction.
The new input method that turns to regular attribute codes depends on the structure at crossing and the relative position and the forbidden rule of entry and exit fully, the content of revising can be resequenced to the crossing that junction node connects by the software program that weaves, according to the position at deletion or newly-increased crossing, successively the value of banning of turning movement rule is upgraded.So just can accomplish to increase or delete the crossing and need not revise the purpose of banning of turning movement regular record.Revise phenomenon meeting ubiquity in the navigation data production run, the elimination of frequent modification banning of turning movement regular record reduces the workload of data edition of knowing clearly, thereby the quality and the efficient that have influence on data production are improved greatly.
Description of drawings
Fig. 1: the recording method example of banning of turning movement traffic rules during existing navigation data is produced.
Fig. 2: change the crossing coding rule over to from anterior approach section and each in the invention.
Further specify below in conjunction with accompanying drawing and the objective of the invention is how to realize:
Embodiment
In order to overcome prior art defective in the crossing banning of turning movement identification record production process in automated navigation system.The input method that the banning of turning movement that relates to is identified redesigns.This method is to realize that by means of computor-keyboard said input method is finished by following steps under the support of GPS navigation software and electronic chart:
1. at a selected crossing cr that road inLink working direction is reached, 0-N flowing water numbering is carried out according to the order that is rotated counterclockwise in each road junction that links to each other with this crossing cr point, the flowing water sequence number of wherein selected road inLink outlet is made as 0, is followed successively by 1-N according to each import sequence number of counter clockwise direction;
2. a N bit be set be the limited code that turns to that enters behind this road inLink along cr place, crossing that working direction reached, the figure place of this binary number is corresponding to the number of the flowing water at the target crossing that will change over to numbering, and the numerical value of the sign indicating number corresponding with target crossing numbering was 1 in this binary number when target crossing limit changed over to, not limit the numerical value of this yard position when changing over to be 0;
