Description

  The present invention relates to a system and a program for assisting taxi dispatch.

  Conventionally, in a taxi company, an operator (a dispatcher) decides how many taxis to install in a plurality of standby places in the business area in consideration of the day of the week and the time zone. Also, especially in rural areas, it was more efficient to move from the waiting area to the pick-up vehicle than to acquire customers by sinks, and the company was effectively managed by the operator.

  However, the conventional allocation of vehicles is largely dependent on the intuition of the operator, and there is a problem that it is difficult to know whether the allocation is really efficient.

  In addition, when a call is received from a user (customer) and the operator responds, for example, “It is crowded and it takes about 15 minutes to go there”, it is refused as “ It is often the case for another taxi company. There is a reality that it is quite difficult for even experienced operators to reduce such lost opportunities or to optimally arrange taxis so that they do not take 15 minutes.

  Also, even within taxi companies, there are many differences in business results depending on the driver, and there is dissatisfaction that the operator is hesitant about a specific driver and dispatches to a waiting place with a higher turnover rate. Sometimes In other words, there is a problem that the dispatch is not objective.

  The present invention has been made in view of the above, and it is an object of the present invention to provide a vehicle allocation assistance system and program that are objective and enable optimal taxi deployment.

  The vehicle allocation assistance system according to claim 1 includes usage information storage means for storing usage information, which is information including the date and time of getting on and off the taxi in the past, and weather, events and other factors that affect taxi use. Area that is information including factor information storage means that stores factor information, which is information including influential factors and weights of the influential factors, a divided area obtained by dividing a taxi sales area, and a taxi waiting place Area information storage means for storing information, date and time input means for inputting date and time, factor setting means for setting influence factors, date and time input by date and time input means, and usage information and area stored by usage information storage means Based on the area information stored in the information storage means, the division of which standby area is responsible for which divided area at the date and time and the standby area Or it is memorized by the reference division allocation determination means for determining the reference division allocation with the number of taxis to be turned in the division, and the influence factor and factor information storage means set by the factor setting means Based on the weights of the influencing factors, the appropriate zoning deployment determining means that corrects the standard zoning deployment determined by the standard zoning deployment determining means and determines the appropriate zoning deployment, and the appropriate zoning deployment determining means. And an appropriate partition allocation output means for outputting the corrected appropriate partition allocation.

  In other words, the invention according to claim 1 is suitable for the date and time by adding the influence factors that are fluctuation factors or external factors to the zoning and taxi allocation number (number of dispatched vehicles / deployment number) that are assumed to be valid at the date and time. Assists the operator with the assumed zoning and taxi assignment.

The weight is a numerical value that causes an increase or decrease in the divided areas in the zoning or an increase or decrease in the number of taxi assignments. Although it is good also as a multiplication coefficient in a calculation formula etc., it is not limited to this, It is good also as an addition / subtraction value.
Influential factors can include accidents, construction, special days, etc. in addition to the weather and events exemplified. Depending on the mode of use, factors that should be considered as usage information such as days of the week and holidays may be used as factors. The day of the week and weather affect the entire sales area, while accidents and construction affect a relatively narrow area. Therefore, the weight is not necessarily uniform, and may be different depending on the divided area or division.
The divided areas may be subdivided according to addresses, or may be subdivided by a road network or the like. Although the division | segmentation which does not overlap is a principle, it is not necessarily limited to this. The area information may include map information.
The taxi waiting place includes both a unique waiting place that can be used only by the taxi company and a general taxi waiting place (a so-called taxi stand) such as in front of the station.
Entering the date and time includes setting the date and time, and may use a predetermined time such as every hour, and is broad.
In the said date and time, you may give width | variety, such as the predetermined time (for example, 30 minutes) after that including the said date and time.
Ward allocation can also be expressed as a shared area. It includes a mode in which the division is dynamically changed according to the date and time (including a mode in which the divided area is increased or decreased).
In the proper division allocation, the number of assignments may not be an integer depending on the coefficient, but may be rounded off as appropriate, or the operator may carry out rounding up or down.
For example, the output is drawn together with the map on the monitor, but may be printed or voice output.

  The vehicle allocation assistance system according to claim 2 is the vehicle allocation assistance system according to claim 1, wherein the standard allocation allocation determined by the standard allocation allocation determining unit is after the date and time input by the date and time input means. It is characterized by comprising change determination means for determining the date and time of change, and change date and time output means for outputting the date and time determined by the change determination means.

  In other words, the invention according to claim 2 enables the vehicle allocation in anticipation of the next deployment. For example, when a taxi dispatched from a waiting place in ward division A drops a user at warding part B, depending on the situation, it may be left as it is in the waiting place in ward part B. It can also be directed to the waiting area inside. Depending on the mode of use, it is possible to preferentially rearrange drivers with low results.

  Needless to say, the usage information stored in the usage information storage means is used for the determination. The factor information is used as it is.

  The vehicle allocation assistance system according to claim 3 is a vehicle allocation assistance system according to claim 1 or 2, wherein the lost opportunity input means for inputting the date and place of the loss opportunity for a lost opportunity that was not found while looking for a taxi. And a lost information storage means for storing the date and place input by the lost opportunity input means, the reference division allocation determining means is also based on the date and location stored by the lost information storage means, It is characterized by deciding the standard division allocation.

  That is, the invention according to claim 3 can substantially enhance the usage information and increase the profit of the company.

  It should be noted that the input mode may be such that the driver uses a taxi radio to send a message to the operator, or that an input device is provided in the taxi and the driver presses a button to store it. Alternatively, a telephone call that has been called by the operator but could not be finally dispatched (rejected) may be input.

  The vehicle allocation assistance system according to claim 4 is the vehicle allocation assistance system according to claim 1 or 2, wherein the usage information stored in the usage information storage means and the appropriate allocation allocation determined by the appropriate allocation allocation determining means. The present invention is characterized by comprising optimization means for optimizing the division and / or weight so as to minimize the excess or deficiency of the deployment based on the history.

  In other words, the invention according to claim 4 can bring the prediction closer to reality as the system is operated, reduces the dependence on the operator, and realizes the most efficient dispatch.

The weight is not always constant and may be changed according to the date and time.
Optimization should be done in a timely manner. For example, the processing is started at 3:00 am unclear from the viewpoint of load distribution.
As a method of optimization, for example, a least square method can be used. A complement formula may be used.
The optimized result is reflected in the factor information. However, the evaluation items to be optimized are not necessarily limited to the optimization of the zoning and the number of allocations based on it, but may include the fare (company sales). This is because lost opportunities have decreased, but it is necessary to consider the case where the overall sales of the company do not grow. Further, the evaluation items may be optimized including reducing the difference in the sales of the driver.

  The vehicle allocation assistance program according to claim 5 is a computer, wherein the computer uses the usage information storage means, factor information storage means, area information storage means, date and time input means, factor setting means, reference division allocation determination means, It is made to function as a proper division allocation determination means and a proper division allocation output means.

  In other words, the invention according to claim 5 is suitable for the date and time by adding the influence factors that are fluctuation factors or external factors to the number of divisions and the number of taxi allocations (number of dispatched vehicles / deployment number) that are assumed to be valid at the date and time. It is possible to provide a computer program that assists the operator by making the assumed zoning and taxi assignment.

In addition, a computer can be functioned as each means of Claims 2-4.
That is, in the vehicle allocation assistance program according to claim 5,
Computer,
A change determination means for determining a date and time after the date and time input by the date and time input means and when the reference zoning deployment determined by the reference zoning deployment determination means changes; and
Change date output means for outputting the date determined by the change determination means;
It is good also as a dispatch assistance program characterized by making it function as.

Further, in the vehicle allocation assistance program according to claim 5 or the above,

  As illustrated, the vehicle allocation assistance system 1 includes a computer device 10 operated by the operator Op and an input device 20 disposed in the taxi T.

  Next, the hardware configuration of the vehicle allocation assistance system 1 will be described. FIG. 2 is a block diagram illustrating a hardware configuration example of the vehicle allocation assistance system 1.

<Vehicle allocation assistance system 1: hardware configuration of computer device 10>
Of the vehicle allocation assistance system 1, the computer device 10 includes a CPU 101, a ROM 102, a RAM 103, a hard disk (HD) 104, a graphics card 105, a monitor 106, and a keyboard (K / B) 107 as hardware configurations. A mouse 108 and a LAN card 109.

  The CPU 101 controls the entire computer device 10 together with the OS, and in particular dynamically determines the division of the business area and the number of taxi assignments in the division. The CPU 101 also performs control for temporarily saving work data stored in the hard disk 104 in the RAM 103.

  The ROM 102 stores a boot program and the like. Depending on the mode of use, the ROM 102 may store a control program for the computer device 10.

  The RAM 103 is used as a work area for the CPU 101. Specifically, usage information, factor information, area information, lost opportunity information, and the like read from the hard disk 104 are temporarily stored.

  The hard disk 104 stores an operating system (OS), application programs, and various types of information. The configuration of the hard disk will be described later.

  The graphics card 105 transmits an image signal to be output to the monitor 106. Specifically, a map of the business area, a waiting place, and a taxi place such as a rent are sent to the monitor 106. The graphics card 105 also includes a VRAM that stores an image signal to be output and an image output interface (image output I / F) that outputs the processed image signal to the monitor 106. The image output I / F outputs RGB image data expanded in the VRAM to the monitor 106.

  The LAN card 109 connects the computer apparatus 10 to the network N. By connecting to the network, lost opportunity information and boarding / exiting history are received from the input device 20. In addition, the computer device 10 can also be equipped with a CD-ROM drive device or the like.

The hard disk 104 will be described in detail. The hard disk 104 includes an application unit 110 and a database unit (DB unit) 130.
The application unit 110 includes an OS 111 that controls the entire computer device 10, a division of which waiting area is in charge of which divided area, and a number of taxis to be turned within the waiting place or the division ( And a zoning allocation program group 112 that determines the number of vehicles dispatched).

The ward allocation program group 112 is

A management program 124 for performing data input / output management with the input device 20 and the DB unit 130;
An optimization program 125 that performs optimization processing in a timely manner so that the number of divisions and taxi allocations is optimized;
Have

  Note that the above-described program describes a group of programs that are aggregated from the viewpoint of division and deployment determined by the computer apparatus 10, and an actual program is configured by a number of components, DLLs, and the like. The functional configuration to be described later can be realized in various ways by a single or a plurality of these programs in some cases in cooperation with the DB unit 130.

  Next, the DB unit 130 will be described. The DB unit 130 includes a usage information storage unit 131 that stores usage information, which is information including the date and time of getting on and off of a taxi user in the past, and weather, events, and other influencing factors that affect taxi use. A factor information storage unit 132 that stores factor information, which is information including the weight of the influential factor, a division area based on map information and divided into taxi sales areas, and a taxi waiting place. An area information storage unit 133 that stores area information that is information, and a lost information storage unit 134 that stores lost opportunity information that is information on the date and place of missed opportunities.

  The DB unit 130 updates timely use information and lost opportunity information from a radio from a taxi, a data logger, or a storage device, and is expanded as needed.

<Vehicle allocation assistance system 1: hardware configuration of input device 20>
Next, the hardware configuration of the input device 20 will be described.
Of the vehicle allocation assistance system 1, the input device 20 includes an input button 21, a GPS unit 22, and a wireless communication unit 23 as its hardware configuration.

  The input button 21 is a push button that is easy for the driver to operate. The input button 21 also inputs customer information. That is, if it is pressed once, it indicates that there was a customer who failed to pick up along the road, and if pressed twice, it indicates that there was a customer who failed to pick up on the other side of the road.

  When the input button 21 is pressed, the GPS unit 22 stores the date and time (including information on whether the road is on the opposite side). That is, the lost opportunity information is stored.

  The wireless communication unit 23 transmits the current position of the taxi and lost opportunity information to the computer device 10. This transmission may be performed when the taxi returns to the office or may be transmitted as needed.

<Vehicle allocation assistance system 1: Functional configuration>
Next, the functional configuration of the vehicle allocation assistance system 1 will be described. FIG. 3 is an explanatory diagram showing an example of a functional configuration of the vehicle allocation assistance system.

  The vehicle allocation assistance system 1 includes, as its functional configuration, a date and time input unit 201, a factor setting unit 202, a reference division allocation determination unit 203, an appropriate division allocation determination unit 204, and an appropriate division allocation output unit 205. , A change determination unit 206, a change date output unit 207, a lost opportunity input unit 208, and an optimization unit 209.

  The date input unit 201 inputs date and time. The operator Op inputs, for example, a numerical value obtained by typing the current time or designating a time after 20 minutes. It should be noted that a mode in which a “current time” button, a “10 minute unit until one hour later” button, and the like are appropriately drawn on the screen and clicked is also included. Further, the case where the preset time, for example, every 30 minutes including every hour is set, is not included in the input by the operator Op.

  The date and time input unit 201 can realize its function by, for example, the keyboard 107, the mouse 108, the input setting program 122, and the like.

  The factor setting unit 202 sets an influence factor. The operator Op inputs and sets weather, event information, and the like. In particular, rain information is quickly reflected in the system, such as by capturing a real-time rainfall map. The event information can be set as appropriate even when the end time is not always constant, such as a baseball night game. Factors such as small-scale events and accident information do not necessarily affect the entire sales area, and there are local factors. Therefore, you may enable it to input an influence factor for every division or every division area.

  The factor setting unit 202 can realize its function by, for example, the keyboard 107, the mouse 108, the input setting program 122, and the like.

  Based on the date and time input by the date and time input unit 201, the usage information stored by the usage information storage unit 131, and the area information stored in the area information storage unit 133, the reference division allocation determination unit 203 A reference divisional deployment is determined, which is a division of which waiting area is responsible for which division area and the number of taxis to be routed in the waiting area or the division. That is, based on the past business results or history, the zoning and the number of dispatches that are considered appropriate at the date and time are determined.

  For example, on weekdays, from 18:00 to 22:00, it can be said that there are many taxis in downtown. Therefore, during that time period, the divisions assigned to each taxi waiting area in the downtown area are determined, and a predetermined number of taxis are deployed. Similarly, in the morning of the first day of consecutive holidays, many taxis are deployed at the station waiting area. Note that the zoning is dynamic. For example, after 21:00, the waiting area in the vicinity of the residential area is in charge of an area larger than the division area so far. The concept of the dynamic change of the division is shown in FIG.

Further, the reference division allocation determination unit 203 determines the reference division allocation based on the lost opportunity information stored by the loss information storage unit 134. In other words, the lost opportunity information is information according to the usage information, and by supplementing with the lost opportunity information, more appropriate deployment and division are possible.

  The reference division allocation determining unit 203 can realize its function by the CPU 101, the determining program 123, the management program 124, the RAM 103, the usage information storage unit 131, the lost information storage unit 134, and the like.

  The appropriate partition allocation determining unit 204 is determined by the reference partition allocation determining unit 203 based on the influence factor set by the factor setting unit 202 and the weight of the influence factor stored by the factor information storage unit 132. Modify the standard zoning and determine the appropriate zoning. In other words, the standard zoning is corrected in consideration of external factors such as weather and events.

  For example, an international conference may be held at a university or a certain hall, but this is not a regular event but a spot event. Therefore, when there is such a meeting, the number of deployments (taxi allocation number) is increased by reassembling the airport and the surrounding standby areas more appropriately. In addition, if heavy rain falls during the time when the office worker returns home, the station and the waiting area nearby will be reassembled to increase the number of deployments. In addition, when high temperature warnings are issued in summer, the number of places around tourist spots should be increased. Individual specific modifications are appropriate zoning.

  Here, the weight is important for the correction from the standard allocation. When the number of deployments in an area is H, when the weight of the weather factor is α, the temperature factor is β, and the event factor is γ, the modified deployment number H ′ is, for example, H ′ = α × (H + β) + γ.

  The appropriate partition allocation determination unit 204 can realize its function by, for example, the factor information storage unit 132, the determination program 123, the management program 124, the RAM 103, the CPU 101, and the like.

  The appropriate partition allocation output unit 205 outputs the appropriate partition allocation corrected by the appropriate partition allocation determination unit 204. Here, the image is drawn on the monitor 106. That is, as shown in FIG. 5, based on a map that covers an approximate business area, a mark (●) of a standby location, a boundary display indicating how far the standby location is responsible, and GPS information The location of each taxi (small dot) is displayed. In addition, tracks, stations, and main roads are also drawn (actually, detailed roads are also drawn on the map, but are omitted here for convenience of explanation).

  A blowing line extends from each standby place, for example, (3-6) / 9 → 10 is displayed. 3 is the number of taxis waiting in the waiting area, 6 is the number of taxis that are paid out by renting or receiving cars, etc., in the ward allocation, and 9 is the number of deployments determined by the appropriate zoning deployment determining unit 204 It is. Reference numeral 10 denotes the number of deployments required in the next time zone determined by the change determination unit 206. With such a display, the operator can visually recognize the current situation efficiently and rearrange taxis in anticipation of the future.

  The appropriate partition allocation output unit 205 can realize its function by, for example, the monitor 106, the graphics card 105, the drawing program 121, the area information storage unit 133, and the like.

  The change determination unit 206 determines the date and time after the date and time input by the date and time input unit 201 and when the reference zone allocation determined by the reference zone allocation determination unit 203 changes. Thereby, the operator Op can know a temporary standard of how long the current division and deployment will continue. In practice, it is common for changes to occur more quickly depending on the influencing factors, but it is possible to know a rough guideline and to optimize vehicle allocation.

  This guideline can be used in reverse. In other words, today, if the zoning is good and there is no movement in another place, there is no change for 2 hours, so you can turn a little more taxi into a good division. I can judge.

  The change date output unit 207 outputs the date determined by the change determination unit 206. Actually, as shown in FIG. 5, the number of minutes until the change time is displayed on the upper right of the screen.

The change determination unit 206 can realize its function by, for example, the usage information storage unit 131, the determination program 123, the CPU 101, the RAM 102, and the like.
The change date output unit 207 can realize its function by, for example, the drawing program 121, the monitor 106, the graphics card 105, and the like.

The lost opportunity input unit 208 inputs the date and place of the lost opportunity for the lost opportunity that cannot be dispatched while searching for a taxi. In the present embodiment, the input is triggered by pressing a taxi input button, and data is skipped to the computer device 10 by the wireless communication unit 23 via the GPS unit 22.
The function of the lost opportunity input unit 208 can be realized by the input button 21, the GPS unit 22, the wireless communication unit 23, the LAN card 109, the management program 124, the lost information storage unit 134, and the like.

  Based on the usage information stored in the usage information storage unit 131 and the appropriate zoning deployment history determined by the appropriate zoning deployment deciding unit 204, the optimization unit 209 determines that the allocation excess / shortage is minimized. Optimize splits and / or weights. In other words, the forecast and the actual result are reviewed at any time, the division and weight are changed, and the optimum setting is performed. Since taxis can be deployed without excess or deficiency, the driver will not have to wait too long, have a moderate tension, and can take a proper vacation. As a result of relieving stress, it can be expected that the driver will respond better to the passengers in a reflective manner. On the other hand, the company does not need to own more vehicles than necessary, and management efficiency can be improved.

  For the optimization, a least square method may be used, or an SOM technique or a big data technique may be used.

  The optimization unit 209 can realize its functions by the CPU 101, the RAM 102, the optimization program 125, the DB unit 130, and the like.

  As described above, the vehicle allocation assistance system 1 is objective and realizes optimal taxi deployment.

  Note that the vehicle allocation assistance program of the present invention can be appropriately installed in the computer device 10 and realized as each means in the vehicle allocation assistance system.

  Moreover, you may arrange | position a part or all of the program installed in the computer apparatus 10 on a web server.

The driver may be guided using this system. For example, some drivers may go through places where people do not pass because they want to return to the waiting place soon after getting off the passenger. For such a driver, the operator Op can be guided to go through the xx street to the waiting place x. In conjunction with lost opportunity information, it is also possible to pass through as many lost opportunities as possible.
On the other hand, some drivers take routes that lead them to profitable places. If this system is used, it becomes possible for the operator Op to dispatch a car in consideration of a driver with poor results so as not to cause a jealous feeling between drivers in the company.
In addition, the present system can be applied to, for example, a review of municipal bus routes and a review of timetables.
