[Problems to be solved by the invention]

Since the conventional specific vehicle operation control system is configured as follows, when the driver's indicator is on the ground, information such as operation interval adjustment is displayed by the indicator light, so check while driving. In that 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 overlooking.

Further, the operation instruction device installed on the vehicle simply displays the event to be instructed (for example, the instruction to start in FIG. 7), and is originally intended for the bus driver who 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 every time an arrival vehicle arrives at a specific point P near the terminal by the central processing unit, the arrival vehicle, the next arrival vehicle and the next arrival terminal are arrived. The estimated arrival time of the bus arriving at will be calculated and tracked based on the arrival time (prediction) of the terminal, and the next operating timetable for the arriving vehicle will be confirmed at the point Q immediately before the terminal. When the arriving car arrives at the terminal, obtain the route bus operation management device that displays the operation instruction information such as the operation timetable of "Basic timetable" or "Modified timetable" on the operation instruction device on the vehicle. To aim.

[Means for solving problems]

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

[Action]

In the operation instruction device according to the present invention, operation instruction information enabling the operation at the current interval is created from the predicted value of the arrival time at the terminal by the route bus operation management device, and the operation instruction information is transmitted to the roadside device of the terminal. When arrives, operation instruction information such as the operation timetable (after departure from the terminal, passing time to the return point via the stop and return time) is displayed on the operation instruction device in the vehicle, so you can get the timetable according to the traffic information. 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 an operation instruction device, (87) is a vehicle antenna, (88) is a traveling direction, and (89) is a traveling route.

FIG. 3 is a diagram showing a timetable and a basic timetable predicted to arrive at the terminal.

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

Fig. 5-a and Fig. 5-b show the case-by-case treatment of diamond correction.

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

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

Next, the operation will be described. As in the conventional method, the bus arrival time is predicted as shown in Fig. 1 at the points A, B, C.
Place (12a) to (12c) along the travel route (89) and
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 point of the bus. Therefore, it is possible to predict the passage time before the road machines (12a) to (12c) on the travel route (89) of the route 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 travel route, the traffic flow changes momentarily. Therefore, since the latest passing data has the highest reliability, weighting the actual required time of several buses that passed each section in the past, giving an average value, and passing the roadside machine that passed immediately before It is calculated by adding a value based on the past data to the actual time value.

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 the 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 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 the operation instruction information when the arrival vehicle arrives in front of the roadside machine (12r) of the terminal, by the communication between the onboard machine and the roadside machine. Displayed in (17).

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 there is a delay due to traffic conditions, one driver will continue for several strokes (one stroke = 1 operating time = 1 round trip), so
If there is a margin in the total value for the waiting time, after a few strokes, the basic timetable will be returned (recovered). For example, the waiting time for one stroke of the diamond shown in FIG. 3 is A + B. Further, in the figure, "3 minutes" is displayed at the starting point and the ending point, which 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 in the figure is defined as follows.

It shows the range of delay or extension from the departure time of the basic diamond at the terminal, based on the arrival time of the terminal at the terminal, and d (minutes) from the waiting time at the start / end points
3 = 3 (min) × 3 = 9 (min) is subtracted (β = A + B-9).

Further, t in the figure is defined as follows.

When it is predicted that the basic diamond can be recovered after the next or subsequent strokes, it is a stretch set value set beyond the range of β.

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

In case A, the diamond is 'and the diamond is', and both arrive (predict) at the terminal within the adjustment time, and therefore the schedule is corrected (from the basic schedule) and the basic schedule is followed.

In case B, the diamond is' within the range of 3 + β ₁ ,
Beyond the range of 3 + beta ₂ with diamonds', since arriving in the range of t, with stretching the diamond by d _2, diamond also adjusted by d _1, thereby departure at h _{1, 2} close at regular intervals.

In the case of Case C, the diamond reaches the range of t beyond the range of 3 + β _{1 in} the case of t, and the diamond reaches the range of 3 + B _{2 in the case} of ', so that the diamond is stretched by d ₁ and
Adjust the diamonds by d _{2 as} well, and start at h ₁ and ₂ that are close to each other.

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 the diamonds for three units in the combination of the cases A, B, and C, there are seven cases of the units 5-a and 5-b. (However, when all arriving cars, next arrivals and subsequent arrivals arrive within the adjusted time, the departure may be according to the basic schedule, and here only the case with a schedule modification is targeted.) Figure 5-a and Summarizing each case in Fig. 5-b, the way to correct the timetable is predicted to be the latest delay based on the departure time of the basic timetable among arrival vehicles, next arrival vehicles and next arrival vehicles. Based on the bus, the front and rear diamonds are stretched at intervals, and the stretching time is gradually reduced so as to gradually return to the basic diamond, and processing is performed 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, and displays one operation hour (one stroke) from the terminal in the operation time table.

For example, you can 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 leave at the final stop at Rokko stop at 12:15. : It means to come back to 15.

In the above-mentioned embodiment, the operation instruction information is displayed on the operation instruction device (17) on the vehicle, but a display device (not shown) is provided somewhere in the terminal to display the information up to the terminal of each timetable. It is also possible to display the time (actual result) when passing through the stop on the way along with the estimated time and time of arrival at the terminal of each timetable, which may be displayed in different colors.

Further, in the above 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 arrival at the terminal, a roadside machine is arranged on the traveling route of the bus, and at the terminal, operation instruction information is transmitted to the bus so that the current traffic situation can be promptly understood. Since the operation instruction information is displayed on the operation instruction device as an operation timetable (1 operation hour), the buses departing from the terminal can be operated at even intervals, and the so-called "dango operation" can be eliminated. Can be of great help. Therefore, it is possible to secure the bus operation according to the timetable, and to encourage the users.
