[Problems to be solved by the invention]

Since the conventional specific vehicle operation control system is configured as described above, when the driver's indicator is on the ground, information such as the operation interval adjustment is displayed by the indicator light, so check while driving. In this case, it is necessary to install a considerably large driver's indicator in order to make it easy to see, and there are problems such as difficulty in distinguishing from other signs and missing.

In addition, the operation instruction device installed on the vehicle merely displays the instructed event (for example, the instruction to leave in FIG. 9), and is intended for the bus driver who originally operates based on the basic timetable. In this case, it is necessary to display the information including time information, and there is a problem that it is difficult to ensure punctuality because there is no operation instruction based on this time information.

The present invention has been made to solve the above-mentioned problems, and each time an arrival vehicle arrives at a specific point P near the terminal by the central processing unit, an arrival vehicle, a next arrival vehicle and a next arrival terminal are arrived. The estimated arrival time of the bus arriving at is calculated and tracked based on the arrival time (prediction) of the terminal, and the next operating timetable of the arriving vehicle is confirmed by passing the arriving vehicle at point Q immediately before the terminal. The purpose is to obtain a route bus operation management device that displays operation instruction information such as the operation timetable of "basic timetable" or "corrected timetable" when the arriving vehicle arrives at the terminal when it arrives at the terminal. And

[Means for solving problems]

The route bus operation management device according to the present invention detects the passage of the bus near and immediately before the terminal to predict the arrival time of the terminal, and the prediction result to the operation instruction device according to the embodiment of the present invention. This operation instruction device is not a simple operation instruction information such as conventional departure and standby, but determines whether the operation according to the basic timetable is possible from the terminal as the operation timetable of the corresponding line, The operation timetable etc. are displayed on the operation instruction device.

[Action]

In the operation instruction device according to the present invention, operation instruction information for enabling evenly-spaced operation is created from the predicted value of the arrival time at the terminal by the route bus operation management device and is transmitted to the roadside device of the terminal. When the train arrives, the operation instruction information such as the operation timetable (after departure from the terminal, the time of the outbound route to the turnaround point via the stop and the time of the return route) is displayed on the in-vehicle operation instructing device, so you can get the timetable according to the traffic situation. Modifications will be made all the time to allow equidistant departures from the terminal. In addition, the bus operation according to the timetable will prompt the arousal of passengers.

Is the traveling direction and (69) is the traveling path.

Figure 3 is expected to arrive at the terminal. It is a diagram which shows a diamond and a basic diamond.

FIG. 4 is a diagram divided into cases according to diamonds arriving at the terminal and arrival conditions of the diamonds.

Fig. 5-a and Fig. 5-b show the case-specific processing for diamond correction.

In FIG. 6, (17) is an operation instruction device, and (171) is an operation instruction unit.

FIG. 7 shows an example of operation instruction of operation information.

Next, the operation will be described. The prediction of the bus arrival time is the same as the conventional one, as shown in Fig. 1, at the points A, B, and C.
Route (12a) to (12c) along the route (69)
Passage information from (15a) to (15c) is sent to the central processing unit (11) via the line (84
Since it is transmitted via a) to (84c), it is possible to track and manage each bus point. Therefore, it is possible to predict the passing time before the road machines (12a) to (12c) on the travel route (69) of the buses (15a) to (15c). Next, the arrival time / minute predicting means of the central processing unit (11) will be described. When the central processing unit (11) predicts the time required to pass each unit section of the road machines (12a) to (12c) and others (not shown) on the traveling path, the traffic flow changes momentarily. Therefore, since the latest passing data has the highest reliability, weighting is applied to the actual required time of several buses that have passed each section in the past and the average value is given to give the average value Is calculated by adding a value based on the past data to the actual value of.

Figure 2 shows the roadside equipment near the terminal and at the terminal (1
2p) to (12r) are shown. The road machine at point P (12p)
The central processing unit (11) has a role of predicting the arrival time of a bus arriving at the terminal, and the central processing unit (11) collects the passage information of each bus on the travel route shown in FIG. ) Is capable of predicting the arrival of the arrival vehicle, the next arrival vehicle and the next arrival vehicle at the point P based on the passage information. Further, the central processing unit (11) determines the timetable of only the arriving vehicle by using the predicted value when the arriving vehicle passing through the point P among the predicted arrival values passes through the point Q.

The confirmed timetable is transmitted to the roadside machine (12r) of the terminal at the point R through the line (84). Then, this confirmed timetable information, that is, the operation instruction information, is temporarily transmitted to the operation instruction device (17) when the arrival vehicle comes in front of the roadside machine (12r) at the terminal, by communication between the onboard machine and the roadside engine. ) Is displayed.

Next, the diamond interval extension processing means of the central processing unit (11) will be described. FIG. 3 is a diagram of a route bus, in which the horizontal axis represents the time and the vertical axis represents the required time between the start point and the end point.

“Basic” and “basic” mean a basic timetable in a predetermined operation plan, which is usually expressed by a timetable number.
A, B, M, and N are the waiting time at the starting point and the ending point of the diamond and the above. The waiting time is provided in order to absorb the delay time d due to the traffic situation on the way, in addition to the driver's rest time d. In the current bus operation, if a delay occurs due to traffic conditions, one driver will continue to operate several strokes (one stroke = 1 operating time = 1 round trip), so there is a margin in the total value for the waiting time. For example, after a few strokes, it will return (recover) to the basic diamond.
For example, the waiting time for one stroke of the diamond shown in FIG. 3 is A + B. Also, in the figure, "3
Although there is a display of "minute", this means the allowable rest time d of the driver. Further, the definition of the adjustment time in the figure is a value specific to each timetable, and shows the range of the waiting time obtained by removing 3 minutes from the time when the basic timetable starts.

Further, β ₁ and β ₂ in the figure are defined as follows.

It shows the delay or extension range from the departure time of the basic timetable at the terminal, based on the arrival time of the timetable at the terminal. Is subtracted.

FIG. 4 shows the diamond and diamond terminal arrival (prediction) situation, that is, three cases (A, B, C).

In case A, the diamonds are ‘and the diamonds are‘ both and arrive at the terminal (predicted) within the above adjustment time, and therefore the schedule is not corrected (from the basic schedule) and the basic schedule is followed.

Case B, diamonds in the 'diamond in adjusting hours and minutes with', departure at regular intervals h ₁ was adjusted with stretching the diamond only alpha ₂ diamonds also only alpha ₁ since the delay arrives within the range of 3 + beta ₂ Let However, α ₁ and α ₂ are the time for making the intervals even and for stretching the diamond.

In case C, the diamond arrives late within the range of 3 + β ₁ at ′, and the diamond arrives within the adjustment time at ′, so the diamond is stretched by α ₁ and the diamond is also adjusted by α ₂ at equal intervals h. Start at ₁ .

By the way, Cases A, B, and C are the arrival conditions of two diamonds (diamonds and diamonds) at the terminal, and it is necessary to trace three diamonds including the arrival vehicle at the point P. Considering three diamonds in the combination of the cases A, B, and C, there are seven cases shown in FIGS. 5-a and 5-b. (However, all arrival cars, next arrivals, and arrivals one after another may arrive on the basis of the basic timetables when they arrive within the adjustment time. Here, only cases with timetable adjustments are targeted.) Figure 5-a And, to summarize each case of Fig. 5-b, the way to correct the timetable is that the arrival time, the next arrival time, and the next arrival time are based on the departure time of the basic timetable, and the departure time is the latest. Before and after the predicted bus, the front and rear diamonds are subjected to interval drawing processing, and the drawing time is gradually reduced so as to gradually return to the basic diamond, and processing is carried out so as to approach equidistant departure.

Next, the operation instruction information creating means of the central processing unit (11) will be described. FIG. 6 is a block diagram of the operation instruction device (17), and displays operation instruction information in the operation instruction unit (171).

FIG. 7 is an example of the operation instruction information. One operation time from the terminal (one stroke) in the operation timetable
Is displayed.

For example, leave the Rokko stop at 7:05, arrive at the turning point Okamoto stop at 7:48, take a break for a while, leave the Okamoto stop at 7:54, and arrive at the final stop at Rokko stop at 12:12. It means to come back to 15.

Although the operation instruction information is displayed on the operation instruction device (17) on the vehicle in the above-mentioned embodiment, a display device (not shown) is provided somewhere in the terminal to connect to the terminal of each timetable. It is also possible to display the transit time (actual results) on the way to the bus stop, and also display the estimated terminal arrival time for each timetable and display them in different colors.

Further, in the above-mentioned embodiment, the operation instruction section (171) is not limited to the display element, but may be any element such as an EL display element, a CRT display device, a plasma display, a liquid crystal display, etc.

〔The invention's effect〕

As described above, according to the present invention, in order to predict the arrival at the terminal, the roadside machine is arranged on the traveling path of the bus, and the terminal transmits the operation instruction information to the bus, which is suitable for the current traffic situation. Since it is configured to display the operation instruction information on the operation instruction device as the operation time method (1 operation hour), it is possible to plan the bus interval departure from the terminal, which is very useful for eliminating so-called "dango operation". be able to. Therefore, it is possible to secure the bus operation according to the timetable, and to encourage the users.
