In another embodiment of the present invention, use is included in based on the road section ID in the bus location assembly of road section ID represents that the bus information field 603a of the current location of motorbus stores the prediction time of arrival of motorbus at next bus stop in addition, shown in Fig. 6 C.Similarly, use is included in to be represented based on a pair of bus stop sequence number in the bus location assembly of motorbus sequence number in identification highway section that the bus information field 604a of current location of motorbus and use are included in based on a pair of bus stop ID in the bus location assembly of the bus stop ID in identification highway section and represents that the bus information field 605a of the current location of motorbus stores the prediction time of arrival of motorbus at next bus stop in addition respectively, shown in Fig. 6 D and Fig. 6 E.As mentioned above, prediction is 2 byte longs and shows with stopwatch time of arrival.Because based on the bus location assembly of road section ID, represent the position of motorbus based on the highway section that comprises two bus stops, be included in prediction among bus information field 603a, 603b and the 603c and be time of arrival prediction time of arrival in the destination of corresponding road section based on the bus location assembly of the motorbus sequence number in identification highway section and based on the bus location assembly of the bus stop ID in identification highway section.
BSI scrambler 11 is determined the optimum bus location component type of bus line in view of present case, and creates the bus location assembly of the type.For example, if the quantity of motorbus that is in bus stop is more than the quantity that operates in the motorbus between the bus stop, then BSI scrambler 11 is created based on the bus location assembly of bus stop sequence number so that improve degree of accuracy about the information of bus location, and provides the bus location of being created assembly to terminal.Because be longer than bus information field, so can be by selecting reduce the size of needed data based on the bus location assembly of bus stop sequence number based on the bus stop sequence number based on the bus information field of bus stop ID.If do not define the bus stop sequence number between BSI scrambler 11 and terminal, then 11 establishments of BSI scrambler are based on the bus location assembly of bus stop ID.Be less than the quantity that operates in the motorbus between the bus stop if be in the quantity of the motorbus of bus stop, then BSI scrambler 11 create bus location assembly based on road section ID, based on the bus location assembly of the motorbus sequence number in identification highway section or based on the bus location assembly of the bus stop ID in identification highway section, so that improve the degree of accuracy of positional information.Yet, having precedence under the situation of positional information degree of accuracy in the reduction size of data, BSI scrambler 11 can be created the bus location assembly based on the bus stop sequence number.
In order to transmit the required time of each highway section that comprises two continuous bus stops along the bus line process, BSI scrambler 11 is created the Link Travel Time assembly according to the sentence structure shown in Fig. 6 F, promptly has the BSI assembly of identifier 0x85.The information that the Link Travel Time assembly comprises the employed bus information bsi01_xx of system of expression, is used for the bus line ID of unique each bus line of identification, is positioned at the quantity 561 of bus line bus stop along the line and represents the Link Travel Time field 560 of the time that process bus line each highway section along the line is required.This Link Travel Time assembly comprises that sequentially process starts from the required time of each highway section at the bus line starting station, but is not that unique ID is distributed in each highway section, thereby effectively reduces the size of the data that need transmission.The quantity 561 of bus stop does not comprise the starting station on the bus line, so the quantity of Link Travel Time field equals the quantity 561 of bus stop.
In another embodiment of the present invention, the quantity 561 of bus stop comprises the starting station on the bus line.In this case, the quantity 561 of bus stop is Duoed one than the quantity of Link Travel Time field, and the quantity 561 of decoding of public traffic information receiving terminal and bus stop deducts 1 as many Link Travel Time field.
In order to transmit the additional information of bus line, BSI scrambler 11 is created route additional information assembly according to the sentence structure shown in Fig. 6 G, promptly has the BSI assembly of identifier 0x86.Route additional information assembly comprises the information of representing the employed bus information bsi01_xx of system, the bus line ID that is used for unique identification bus line, bus service name 571 and at least one additional service information field.Bus service name 571 is the motorbus number of expression bus line or the information that comprises the destination of this motorbus number and motorbus.Alternatively, bus service name 571 can be the combination of bus company title and other types information.
The schedule time 574, motorbus working time that the additional service information field can comprise bus line type 572, bus company title 573, operate in the first bus on this bus line and last bus at interval 575, motorbus concentration zones 576 and bus line turn round a little 577 and the identifier of representing information type.
According to the type of bus line, the bus line type 572 with the sentence structure shown in Fig. 6 H has the value such as " intercity ", " main line " (or " doing ") or " branch line " (or " propping up ").
Have the sentence structure shown in Fig. 6 J operate in the first bus on the bus line and the time 574 of last bus has two fields 611, be used to store first vehicle hour and final vehicle hour, these two fields all are shown in Fig. 7 A＜specific_﹠amp; _ iterative_time〉type.
Shown in Fig. 7 A＜specific_﹠amp; _ iterative_time〉sentence structure of type has the selector switch of bit switch type.If each position of selector switch all is arranged to 1, then this has the value of 1 byte of the correspondence after selector switch.If two or more positions of selector switch are arranged to 1, then two or more bytes early occur with the data that are associated than low order of selector switch after selector switch in this case.For example, if＜specific_﹠amp; _ iterative_time〉data of type are " 58h 07h 15h ", then three positions of selector switch (58h) are configured to 1.Each implication of selector switch has been shown among Fig. 7 A.In this example, selector switch 58h represents that unappropriated field uses current date and time, and hour and minute be worth after selector switch.Because corresponding to hour the position than corresponding to minute the position more approach LSB, and corresponding to hour, minute and second each field all store than actual value and Duo 1 value, so following data " 07h 15h " are represented 6 hours and 20 minutes.Other fields such as second, day and year obtain from current date and time.Therefore, if current date is on October 12nd, 2006, then value " 58h07h 15h " is meant the 6:20 on October 12nd, 2006.In another example, if＜specific_﹠amp; _ iterative_time〉data of type are " 50h 15h ", then it represents that unappropriated field uses current date and time, and minute value is after selector switch.In this case, if current date and time is 6 points on October 12nd, 2006, then these data are meant the 6:20 on October 12nd, 2006.The time that transport information provides server 100 to encode the first bus and last bus by this way, and data encoded is stored in the corresponding field 611.
The first bus and final vehicle hour 574 comprise represents the included first bus and final vehicle hour are applied to field when 612 weekly.The information that is stored in the field 612 is followed the sentence structure shown in Fig. 7 B.As shown in the figure,＜day_selector〉type definition the value of 1 byte, and each of its lower 7 was corresponding to weekly one day.The MSB of this value represents whether the included first bus and final vehicle hour repeat in this day weekly by its low 7 appointments.For example, 1 byte value of 01h represents that the first bus and final vehicle hour are applied to Sun..Similarly, 1 byte value of C0h represents that the first bus and final vehicle hour are applied to each Saturday.
Motorbus interval working time 575 has the sentence structure shown in Fig. 6 K or Fig. 6 L.If motorbus is always constant at interval working time, then use the sentence structure shown in Fig. 6 K.If motorbus working time at interval according to weekly when or which of every day change constantly, then use the sentence structure shown in Fig. 6 L.According to the coding of the sentence structure shown in Fig. 7 C motorbus working time of information at interval.
