(Operation of Example 1)
FIG. 11 is an operation explanatory diagram of the first embodiment, and is an operation explanatory diagram when the next arrival bus (BUS2) is traveling between the bus stop S2 and the bus stop S3.
FIG. 12 is a graph showing the difference in bus arrival time at each bus stop in FIG. 11, with the vertical axis representing the difference in bus arrival time and the horizontal axis representing the bus stop.
FIG. 13 is an operation explanatory diagram of the first embodiment, and is an operation explanatory diagram when the next arrival bus (BUS2) does not leave the first bus stop S1.
The operation of the bus waiting time display system S according to the first embodiment having the above configuration will be described with reference to FIGS.

  In FIG. 11, the bus route having the first bus stop S1 and the bus stops S2, S3, S4,... Is running, and the time when the bus BUSm arrives at the bus stop Sn is defined as tBUSm_Sn. In the case shown in FIG. 11, when the designated bus stop is the bus stop S4, the bus BUS2 arrives at the designated bus stop S4 next, so that the bus BUS2 is searched as the next arrival bus (see ST24). The bus BUS2 departs from the first bus stop S1, and the immediately preceding bus stop that passed immediately before is searched (determined) as the bus stop S2 (see ST25 and ST26). Next, since the bus preceding the next arrival bus is the bus BUS1, the bus BUS1 is searched as a past bus (see ST28). Then, a bus arrival time difference (see FIG. 12), which is a time difference between the passage times tBUS1_S2 and tBUS2_S2 of the buses BUS1 and BUS2, at the immediately preceding bus stop S2 is calculated (see ST31). Then, it is estimated that the time difference between the past bus BUS1 and the next arrival bus BUS2 is held at each bus stop, and the past bus passing time tBUS1_S4 when the past bus BUS1 passed the designated bus stop S4, the current time, The bus waiting time at the designated bus stop S4 is calculated from the arrival time difference (see ST32).

  Further, as shown in FIG. 13, when the next arrival bus BUS2 has not yet departed from the first bus stop S1, the immediately preceding bus stop is set to the first bus stop S1, and the scheduled departure time of the timetable is next to the next arrival bus BUS2. The arrival bus passage time tBUS2_S1 is set (see ST25 and ST27). Then, a bus arrival time difference is calculated based on the transit times tBUS1_S1 and tBUS2_S1 of the immediately preceding bus stop S1 (see ST31), and a bus waiting time is calculated (see ST32).

Therefore, in the bus waiting time display system S according to the first embodiment, the waiting time of the next arrival bus (BUS2) that arrives next at the designated bus stop (S4) designated according to the user input is the same as the designated bus stop (S4). It is calculated based on the time difference from the previously passed bus (BUS1). As a result, it is possible to accurately obtain the bus waiting time based on the passage time of a bus stop that is easily available without using information on the actual traveling speed of a bus that is difficult to obtain.
Further, in the bus waiting time display system S of the first embodiment, when the next arrival bus (BUS2) does not depart from the first bus stop, the scheduled departure time is set as the next arrival bus passage time. Even waiting time can be calculated. Therefore, the waiting time can be calculated (predicted) even if the bus does not actually move, and an accurate bus waiting time can be calculated even when the designated bus stop is close to the first bus stop.
Furthermore, in the bus waiting time display system S of the first embodiment, the user can know the bus waiting time by using the mobile phone 1, which is highly convenient.

Next, the bus waiting time display system S according to the second embodiment of the present invention will be described. In the description of the second embodiment, components corresponding to the components of the first embodiment are denoted by the same reference numerals. Detailed description thereof will be omitted.

In FIG. 14, the bus waiting time distribution server 7 of the second embodiment has a bus arrival time difference calculating means C19 ′ instead of the bus arrival time difference calculating means C19 of the first embodiment.
C19 ′: Bus Arrival Time Difference Calculation Unit The bus arrival time difference calculation unit C19 ′ according to the second embodiment includes a next arrival bus passage time search unit C19A ′, an already-passed bus passage time search unit C19B ′, and a time difference change calculation unit C19C. The time difference between the next arrival bus and the already-passed bus is not only the time difference at the bus stop immediately before passing, but also the time difference at the bus stop that passed before the bus stop immediately before passing is calculated, and the difference in bus arrival time is calculated based on the change in time difference. The bus arrival time difference calculating means C19 ′ according to the second embodiment of the second embodiment is based on the change in the time difference between the time difference at the immediately preceding bus stop and the time difference at the previous bus stop on the route of the immediately preceding bus stop. Calculate the time difference. Therefore, when the time difference becomes larger or smaller as it approaches the designated bus stop, the time difference change corresponding to the ratio is calculated, and the time obtained by adding the time difference change to the time difference at the designated bus stop is calculated as the bus arrival time difference.

C19A ': Next arrival bus passage time search means C19A' is a previous arrival bus stop passage time search means C19A1 for searching for the time when the next arrival bus has passed the immediately preceding bus stop. A time at which the next arrival bus passes through each bus stop, having a previous bus stop passage time search means C19A2 for searching for the time at which the next arrival bus has passed the bus stop immediately before the passing bus stop (the previous bus stop). Search for.
C19B ′: Passed Bus Passing Time Search Means Passed Bus Passing Time Searching Means C19B ′ is a previous pass bus stop passing time searching means C19B1 for searching for a time when the passed bus has passed through the previous pass bus stop, and the previous bus stop. And a previous bus stop passage time searching means C19B2 for searching the time when the already-passed bus passes, and searches for the time when the already-passed bus passes each bus stop.
C19C: Time difference change calculating means The time difference change calculating means C19C calculates the change (time difference change) between the time difference at the immediately preceding bus stop and the time difference at the immediately preceding bus stop for the next arriving bus and the already passed bus.

Next, although the flowchart of Example 2 is demonstrated, since the process of the mobile telephone 1 and the bus operation condition delivery server 8 is the same as that of Example 1, detailed description is abbreviate | omitted.
(Description of processing of the bus waiting time distribution server 7)
FIG. 15 is a flowchart of the bus waiting time distribution process according to the second embodiment, and is a flowchart corresponding to FIG. 9 according to the first embodiment.
In FIG. 15, in the bus waiting time distribution process according to the second embodiment, the following ST31 ′ process is executed instead of ST31 of the bus waiting time distribution process according to the first embodiment.
In ST31 ′ of FIG. 15, the following processes (1) to (4) are executed, and the process proceeds to ST32.
(1) Based on the transit time record table, the time when the next arrival bus passed the previous pass bus stop (passing time immediately before the next arrival bus stop) and the time when the past pass passed the previous pass bus stop (just before the previous pass bus) The time difference (passing bus stop passing time) and the time difference (previous passing bus stop time difference) are calculated.
(2) Based on the transit time recording table, the time when the next arrival bus passed the previous bus stop (the time when the next arrival bus passed the previous bus stop) and the time when the already passed bus passed the previous bus stop (existing) The time difference (the time difference between the previous bus stop) and the time at which the previous bus stop passed) is calculated.
(3) The difference (time difference change) between the difference between the bus stop time immediately before passing and the time difference between the previous bus stops is calculated.
(4) The time difference change is calculated by multiplying the time difference change by the number of bus stops from the immediately preceding bus stop to the designated bus stop, and the bus arrival time difference is calculated by adding the time difference change to the immediately preceding bus stop time difference.

(Operation of Example 2)
FIG. 16 is a graph showing the difference in bus arrival time at each bus stop in the bus waiting time display system S of the second embodiment, where the vertical axis represents the difference in bus arrival time and the horizontal axis represents the bus stop.
In the bus waiting time display system S according to the second embodiment having the above-described configuration, a change in time difference at a plurality of bus stops is calculated, and a bus arrival time difference is calculated in consideration of the time difference change. For example, when a traffic jam occurs on the bus route between the passage of the already-passed bus and the passage of the next arrival bus, the time difference at the bus stop may vary as shown in FIG. In response to this, in the bus waiting time display system S of the second embodiment, the slope of the change in the bus time difference is extended so that the bus arrival time difference at the designated bus stop is larger than the bus arrival time difference at the immediately preceding bus stop. Calculate the waiting time. Conversely, when the generated traffic congestion is going to be resolved, the time difference at the bus stop may fluctuate, but in this case, the bus arrival time difference at the designated bus stop is calculated to be smaller than the bus arrival time difference at the immediately preceding bus stop. The Therefore, the bus waiting time display system S according to the second embodiment can display the bus waiting time in consideration of the time difference of the bus transit time due to traffic congestion or the like. As a result, the bus waiting time can be displayed more accurately than in the first embodiment.

Further, in each of the above embodiments, when determining the time difference between the next arrival bus and the already-passed bus, the time difference of the transit time at each bus stop was used, but is not limited thereto, and a specific intersection or turn on the route, It is also possible to set the interchange, junction, service area, etc. of the expressway in front of the facility as a checkpoint, calculate the bus arrival time difference using the time passing each checkpoint, and obtain the bus waiting time.

Further, in each of the above embodiments, in the case of the first bus in the morning, the position information of the bus is displayed. However, in addition to this, for example, the time difference between the past bus and the next arrival bus is a predetermined time. If there is more than (for example, 30 minutes or 1 hour), it is possible to display the position information without displaying the waiting time. Instead of displaying the position information, it is also possible to display the bus waiting time calculated based on the scheduled passage time of the timetable.
In the second embodiment, the bus waiting time is calculated based on the change in time difference between the two bus stops of the immediately preceding bus stop and the previous bus stop. However, the present invention is not limited to this, and the change in time difference at three or more bus stops is calculated. It is also possible to calculate the bus latency based on At this time, it is also possible to calculate the bus waiting time by linear approximation using the least square method.
