Embodiment
about station board:
As Fig. 1, this station board is comprised of support 1, board body 2, and 3 on board body 2 is that site name, 4 is that station board ID, 5 is circuit and website sequence information thereof, and the website of this station board is ' Yong Songlu '.Station board ID is ' 1263A6 ', and the uniqueness of this station board ID refers to that it is also the station board of ' 1263A6 ' that can not there be second station board ID in same city.In ' 1263A6 ' ' 1263 ' is the station code of this station board place website, and ' A ' is the curbside coding of this curbside, station board place, and ' 6 ' is the concentrated name placement of the station board of this station board in curbside, place.While only having a station board as certain website, can omit when curbside coding and name placement information ，Ru Mou curbside only have a station board and can omit name placement information.
This station board ID can have equivalence to change, as Fig. 2, site name ' Yong Songlu ' forms station board ID Ji‘Yong Song road A6 ' jointly with ' A6 ', although ' Yong Songlu ' and ' A6 ' are not set together, but pro forma separation does not affect these two parts jointly to be formed this station board ID and has uniqueness, this expression mode advantage easily of encoding.
In Fig. 1, station board ID also can be expressed as ' 12630106 ', and wherein encode in ‘01’Shi curbside, and ' 06 ' is name placement; Wherein name placement also can be expressed as ' F ', but this expression mode is insuperior; Also can add therein delimiter, be expressed as ' 1263-01-06 ', ' 1,263 01 06 ', ' 1263-1-6 ' etc., so that passenger reads; Also the order of capable of regulating each several part, is expressed as ' A6-1263 ', ' 01-06-1263 ' etc.Passenger reads station board ID several times just can understand wherein implication, and these represent equivalence.
Can be like this during to station code, imagination is divided the position of this each website of city with the grid of a M*N, if any two websites, drop in (22,35) grid of this grid, these two websites be encoded to 22351,22352.Can also be like this, in down town, get a terrestrial reference, imagination is designated as initial point with this ground and gets plane right-angle coordinate, its four quadrants are numbered respectively A, B, C, D, and imagination is got a M*N grid in each quadrant, if any two websites, fall into (22, the 35) grid in C district, this two website be numbered C22351, C22352.Rear a kind of station code mode has better extendability.
When encoded in curbside, cardinal rule is to take website as the Dui Qige of unit curbside coding.Further, should be according to the distribution pattern Dui Ge curbside coding of curbside in this website, common curbside distribution pattern has single street, T-shaped street, cross street, even can there is ' π ' shape, ' work ' type etc., during coding, to arrange a kind of rule so that passenger grasps and applies, set rule and should be advisable to embody a simple feature.
A coding rule, as Fig. 3, the curbside distribution pattern of this website is ，Liang curbside, single street called after E, F respectively; As Fig. 4, the curbside distribution pattern of this website is T-shaped street, and these curbsides are considered as to 3 called after A, B, C.Ru Tu5， curbside distribution pattern is cross word street, and these curbsides are considered as to 4 called after A, B, C, D.Basic characteristics Shi Ge curbside coding in Fig. 4 and Fig. 5 is in turn counterclockwise distribution centered by T-shaped or intersection.
Determine first curbside coding.As Fig. 8, the street center line XX' of imagination is divided into single street plane on the center line of ，Gai street, ①②Liang region and gets central point O, and from 45 ° of O Dian Qu east by south reference line, reference line falls into ②，Ze Jiang region, region ②Zhong curbside called after E.As Fig. 9, street center line XX' and the OY of imagination are divided into ①②③ region by T-shaped street plane, and XX' and OY intersection point are T-shaped center O, and from 45 ° of O Dian Qu east by south reference line, reference line falls into ③，Ze Jiang region, region ③Zhong curbside called after A.Situation and the T-shaped in cross street are similar.Also desirable is reference line from O point with the line of the city terrestrial reference of agreement.
Special circumstances, take cross street as example, with reference to Figure 10, street center line XX' and the YY' of imagination are divided into ①②③④ region by cross street plane, from intersection point, be that cross center O is got 45 ° of east by south reference line, ③④ boundary line, this reference line Qia Yan region, therefore increase agreement, getting wherein Kao Dong region is that ④Zhong curbside, ，Ji region, region, A curbside is A.These special circumstances in single street or T-shaped street are determined to E or A equally.
On the basis of the above, can divide more accurately curbside.During single street, be encoded to A, B, simpler; As Fig. 6, during T-shaped street, be regarded as 6 curbsides and be encoded to A1, A2, B1, B2, C1, C2; As Fig. 7, during cross street, be regarded as 8 curbsides and be encoded to A1, A2, B1, B2, C1, C2, D1, D2.The basic characteristics of Fig. 7 He Tu8Zhong Ge curbside coding are still centered by center, crossing along distributing in turn counterclockwise, aforementioned A, B, C, D are respectively the combinations of A1 and A2, B1 and B2, C1 and C2, D1 and D2 here, A1 HeA2Shi Yan path positive dirction connects into aforementioned A in turn, other is same, and this corresponding relation has also determined to determine A1 with the same method of determining A.
While determining website Zhong curbside distribution pattern, when meeting, obviously without current Shi，Qi curbside, the lane distribution pattern of public transport, should think single street.Though when certain website is near cross street, its station board distribution is only when Zhong Liang curbside, a bit of street, rule is preferentially judged as single street type according to a preconcerted arrangement.
When encoded in curbside, though Ru Tu7Zhong curbside B1 and C1 are without station board, for not destroying coding rule ，Reng Duigai curbside coding.When encoded in curbside, should not stick to the curbside that station board distributes, because when passenger is during in intersection, which curbside he does not understand there is station board, he is that the integral status distributing according to this website curbside judges what encoded in certain curbside.
For example, ' 1,2,3 ' in three station boards ' 125C1 ' of Ru Tu4，Yan curbside C, ' 125C2 ', ' 125C3 ' is that the positive dirction of sequencing information ，Qi Yangai curbside increases progressively to name placement information.In two station boards ' 125B21 ' in the B2 of Ru Tu6，Yan curbside, ' 125B22 ' ' 1,2' are sequencing informations.
Further, each curbside distribution schematic diagram of station board place website is set on station board, in Figure 11, with lines, represents this Shang Ge curbside, cross street, and mark Liao Ge curbside coding.The coding of curbside, this station board place can not mark in the diagram.If there is no station board on this Mou curbside, cross street, can be dotted.
Further, in Figure 11, also with solid initial point, mark and represent that current station board is in B1Zhong position, curbside, other hollow initial point represents the position of other station board in website.
Further, station board ID is deposited in the database of bus routes inquiry system, and it is associated with corresponding website and circuit, as the situation of Fig. 1, unique circuit of this station board one side forward travel along this section of road that the website associated with ' 1263A6 ' is ' Yong Songlu ' in database, and associated circuit is that name is called ‘11 road ' He‘ 23 tunnels '.
