Description

The present invention relates to a parking lot guidance method, a parking lot guidance device, and a computer program thereof.

In order to avoid traffic congestion caused by an event, a parking lot guidance device that preferentially guides a parking lot away from the event venue is known. This is because when the event is over, the spectators return all at once and the road is congested near the event venue. As an example of such a guidance device, Patent Document 1 describes an electronic device for searching a parking lot around a destination, and when it is determined that the destination is an event venue, the purpose including the destination. An electronic device including a search means for searching a parking lot outside the first range around the ground and a display control means for displaying the parking lot on a display is disclosed.
In addition, the parking lot around the destination is extracted by referring to the parking lot information, the congestion prediction point is determined by referring to the road traffic information, and the route from the parking lot to the preset second destination is determined. When a search is performed and the searched route is an advantageous route, a navigation device that guides the parking lot that is the starting point of the searched route has been proposed (Patent Document 2).
See also Patent Document 3, which discloses prior art related to the present invention.

According to the technique disclosed in Patent Document 1, it is possible to avoid traffic congestion by selecting a parking lot away from the event venue. However, a parking lot away from the event venue means that access from the parking lot to the event venue is burdensome. In other words, it is preferable to select a parking lot that can avoid traffic congestion and is as close as possible to the event venue.
However, no criteria for selecting the parking lot other than the distance from the event venue are disclosed.
On the other hand, according to the technique disclosed in Patent Document 2, although the advantageous parking lot is guided by using the traffic jam prediction, the distance to the event venue is not considered, and in the embodiment, the event is performed from the parking lot. The use of public transportation (so-called park-and-ride) is recommended for transportation to the venue.
There are often many parking lots near the event venue, and the size and number of parking lots vary from event venue to event venue. Therefore, from the standpoint of avoiding congestion, all prior documents recommend parking lots in areas away from the event venue. However, there is no disclosure or suggestion of how far the parking lot should be from the event venue, and any criteria for that.

The present inventors have been diligently studying the criteria for extracting and guiding parking lots that can avoid congestion after the event and that can exist as close as possible to the event venue. As a result, we came to pay attention to the main road. Most cars departing from the parking lot around the event venue merge into the main road. In other words, the traffic on the general road that joins the main road from the event venue is the heaviest, and if you avoid the parking lot that leads to this general road, you can efficiently avoid congestion after the event.
That is, the area including the event venue is specified with reference to or with reference to the main road, and the guidance of the parking lot existing in that area is avoided. In other words, we decided to guide the parking lots outside the area.

The first aspect of the present invention is defined as follows. That is,
It is a parking lot guidance method that prioritizes avoidance of traffic congestion on the way back by selecting a parking lot from outside the first area including the event venue and guiding the user.
The first area is a parking lot guidance method defined based on the main road.

Vehicles leaving the parking lot in the first area including the event venue will join the main road via the general road leading to the parking lot, but the traffic on this general road is heavy. According to the guidance device specified in the first aspect, the parking lot is extracted and guided by removing the first area, so that the parking lot is not caught in the congestion on the way back.
Here, since the first area is specified with reference to the main road, the first area can be set narrower than in the conventional example in which there is no standard. For example, the area opposite to the event venue when viewed from the main road can be set narrow. This is because when returning from the opposite side of the main road from the event venue, a guide route that excludes the main road may be recommended due to the distance cost.
If the first area can be set narrow in this way, the distance from the parking lot outside the first area to the event venue will also be shortened.

Here, the main road refers to a road on which many vehicles are guided when the navigation system is operated with the event venue as the destination, such as a national road existing near the event venue or a road with multiple lanes. More specifically, it refers to the road with the lowest transit cost used when calculating route guidance near the event venue. It is preferable to use a road having a small transit cost that is separated from a predetermined threshold value or more as a trunk road as compared with a road (general road) around the event venue.
When viewed from the event venue, there may be multiple highways.

It is preferable that one boundary of the first area specified with reference to the main road is in contact with the lane facing the event venue on the main road (second aspect). That is, the area between the event venue and the main road is set as the first area. Of course, this first area may extend to the opposite side of the event venue as seen from the main road. The area extending to the opposite side can be made narrower than the area between the main road and the event venue.
In other words, the first area can be widened toward the main road side centering on the event venue and narrowly spread in the other directions.

The third aspect of the present invention is defined as follows. That is, in the guidance method described in the first or second aspect, the parking lot is selected from the second area existing outside the first area.
According to the guidance method of the third aspect defined in this way, the distance between the extracted parking lot and the event venue can be limited by specifying the second area outside the first area. ..
The second area is preferably defined according to a predetermined rule. Here, the predetermined rules include, in addition to the distance from the event venue, the existence or nonexistence of public transportation stations, the density of parking lots, past traffic congestion information, and the like. If there is a station, the waves of people returning from the event venue may hinder driving, and if the parking lot is dense, there is a high possibility of traffic congestion. Needless to say, refer to past traffic jam information.

As a predetermined rule, the area on the opposite side of the trunk road from the event venue can be specified. Since walking across a highway is psychologically burdensome, generally few vehicles are parked in this area and the probability of congestion in this area is low. On the other hand, even on the opposite side of the trunk road, the distance to the event venue may be relatively short. Such an area on the opposite side of the main road is set as a third area, and parking lots existing in this third area can be preferentially guided (fourth aspect).
In particular, when there are a plurality of trunk roads with respect to the event venue, it is preferable that the area on the opposite side of the trunk road closest to the event venue is set as the third area (fifth phase).

The sixth aspect of the present invention is defined as follows. That is, it is a guidance method for any of the first to fifth aspects, and when an event venue is designated as a destination, it is determined whether or not an event is being held.
Only when it is determined that an event is being held, the parking lot is selected from outside the first area.
According to the guidance method of the sixth phase defined in this way, it is located only in the parking lot outside the first area, for example, the second area or the third area only when the event is held at the event venue. You will be guided to the parking lot to do. That is, when the event venue is set as a destination when the event is not held at the event venue, the route to the event venue is guided according to general navigation guidance software, and the parking lot also has general rules. It applies, for example, the nearest parking lot for the event venue is guided. In other words, the parking lot is guided as described above only when the event is held at the event venue where the destination is set. Here, the determination as to whether or not an event is being held may be made by the manual input of the user, or may be based on the information sent from the server via the Internet line.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic representation of a map displaying the event venue I, and a parking lot P is attached to the event venue. Two highways 1 and 2 in the figure are arranged. General roads are indicated by reference numerals A1 to A9 and reference numerals B1 to B9.
Here, the main road 1 and the main road 2 are national roads, respectively, and are roads having two lanes on each side. The transit cost of these trunk roads is X. On the other hand, general roads A1 to A9 and B1 to B9 include narrow streets, and their cost is 3X or more. That is, in this embodiment, a road having a passing cost of 1/3 or less of the passing cost of the road (general road) around the event venue I is defined as a trunk road. When operating a navigation system to perform route guidance for an event venue, most guidance routes select a road whose transit cost is sufficiently low compared to the surroundings with a high probability.

In FIG. 1, reference numeral 11 indicates a first area. The first area 11 is arranged so as to surround the event venue I. The area of the first area 11 in contact with the first highway 1 is wider than the other areas. This is because vehicles from the parking lot P adjacent to the event venue I and the parking lots in the vicinity thereof start running toward the first highway 1 all at once, so there is a higher possibility that traffic congestion will occur than in other areas. Is. Here, the other areas are the area opposite to the first main road 1 and the area parallel to the first main road 1 as viewed from the event venue I.
In FIG. 1, the second highway 2 also appears. The passage cost of the first highway 1 and the second highway 2 is the same. Since the first main road 1 is closer to the second main road 2 when viewed from the event venue I, in this example, the first area 11 is defined based on the first main road 1.

In such a first area 11, traffic congestion of vehicles is predicted with a high probability after the event ends. Therefore, we will guide you to parking lots other than the first area 11. As a result, it is possible to prevent being involved in the traffic jam on the way back.
In this example, the first area 11 is defined based on the general road network. The area in contact with and inside the road selected from the periphery of the event venue I is the first area 11. It is assumed that the selected road includes the main road 1. The criteria of the selected road can be set arbitrarily, but it is assumed that the main road 1 is within a predetermined distance (for example, 1000 m) from the event venue I. Similarly, general roads that exist within a predetermined distance from the event venue I can be selected, but on the other hand, the number of general roads from the event venue I may be selected.

As shown in FIG. 2, the data defining the first area 11 is stored in the map data storage unit 21 in the return route congestion avoidance area storage unit 23 in the guidance device 20. The map data storage unit 25 of the guidance device 20 is provided with a road data storage unit 26 generally used in a navigation system. Road information such as nodes and links and characteristic values of the nodes and links (passage cost, other speed limits, prohibition of turning left and right, etc.) are stored in the road data storage unit 26. The characteristics of each facility are stored in the facility data storage unit 27. Whether or not a facility is an event venue is also stored in the facility data storage unit 27. The parking lot data storage unit 28 stores the coordinates, polygons, names of the parking lot, and other information necessary for identifying the parking lot.
A general-purpose input means represented by a touch panel is used for the input unit 31. In addition to the display, the output unit 34 may also have a voice guide.
The guide unit 33 is composed of a computer device, and when a destination is set and input from the input unit 31, the navigation system searches for the optimum route from the current location to the destination or the route that meets the user's needs, and searches for the route. invite.

In the present invention, the guide unit 33 not only functions as a normal navigation system, but also executes the process shown in FIG.
In step 1, the input destination is compared with the data stored in the facility data storage unit 27, and it is determined whether or not this corresponds to the event venue.
When the entered destination does not correspond to the event venue (step 1 = N), for example, the nearest parking lot is extracted and displayed according to the software of a normal navigation system (steps 2 and 3).
When the input destination corresponds to the event venue (step 1 = Y), it is determined whether or not the event is actually held at the event venue (step 5). Whether or not an event is held can be determined by the navigation system 20 directly accessing the site of the event venue via the Internet or the like. The user can also manually enter whether or not the event is being held. Therefore, when the destination corresponds to the event venue, it is preferable to display the guidance for inputting whether or not the event is held on the input screen of the navigation system.

Even at the event venue, the event is not always held, so when the event is not held (step 5 = N), for example, the nearest parking lot is extracted according to the software of the normal navigation system. Display (steps 2 and 3).
When an event is being held at the event venue I (step 5 = Y), whether or not the first area 11 is set around the event venue I with reference to the return traffic congestion avoidance area storage unit 23. Is determined (step 7). When the first area 11 is set (step 7 = Y), when the first area 11 is read out (step 8), the guidance of the parking lot in the first area 11 is prohibited, and the first area 11 is prohibited. A parking lot outside the area 11 of 1 is extracted (step 9) and guided (step 10). The method of guidance is not particularly limited, but it is based on displaying the P mark on the display.
In the navigation system 20, depending on the scale of the map displayed on the display set by the user, the event venue and the area other than the first area may not be displayed at the same time. Even in such a case, when step 7 is determined to be Y, the scale is adjusted, and the display shows an area other than the event venue I and the first area 11 where the parking lot is displayed. Will be displayed once.

Depending on the event venue I, the return congestion avoidance area storage unit 23 may not have the first area 11 set. In that case, the first area 11 is set each time in step 11, the guidance of the parking lot in the first area 11 is prohibited, and the parking lot outside the first area 11 is extracted (step 11). 9) Guide this (step 10)

A method of setting the first area 11 each time will be described with reference to FIG.
In step 111, the location of the designated event venue is specified. This position can be, for example, the coordinates of the center of the event venue. In step 112, the observation range R is set centering on the position of the event venue. For example, a circle with a radius N = 500 m is set as the observation range R. The maximum value of this radius N is 1000 m (step 113). When the main road exists within the observation range R (step 114 = Y), the first area is selected in step 117. When the main road does not exist in the observation range R, the observation range R is expanded and steps 112 to 114 are repeated.
Here, as shown in FIG. 1, the area surrounded by the main road 1 existing in the observation range R and the general road around the event venue I can be set as the first area 11. In the example of FIG. 1, the outer edge of the first area 11 is defined by using the general roads (A3, A8, B8) close to the event venue I for the sake of modeling, but the scale and holding time of the event venue I Etc., the outer edge can be arbitrarily selected.

The example of FIG. 5 shows a case where two highways 1 and 2 exist within the observation range R. In this case, the first area 12 is defined by two highways 1 and 2 and general roads (A8, B8) close to the event venue I.
FIG. 6 shows an example of geometrically defining the first area 13. When the main road 1 exists in the observation range R, a perpendicular line is drawn from the center of the event venue I to the main road 1, and a virtual isosceles triangle (indicated by a dotted line) with the perpendicular line as the center line is drawn. After that, the perpendicular line is extended 1.5 times with respect to the main road 1 to form outer edge diagonal lines 132 and 133 parallel to the sides of the isosceles polygon from the end point 131. The ends 134 and 135 of the outer edge diagonal lines 132 and 133 are equal to the length of the hypotenuse of the bisector triangle, and the outer edge perpendicular lines 136 and 137 are formed from there to the main road 1. In this way, the area defined by the first highway 1, the outer edge diagonal line 132, 133, and the outer edge vertical line 136, 137 is referred to as the first area 13.

In the example of FIG. 7, when the distance between the event venue I and the first highway 1 is more than a predetermined value (for example, 1000 m) in FIG. 1, the event is held from the lane facing the event venue of the first highway 1. A predetermined range toward the venue I (for example, a range of 200 m or an area defined by an adjacent general road) may not correspond to the first area.
Even in the first area 14 defined in this way, the area on the first highway 1 side is set wider than the other areas.

Next, a second area set outside the first area will be described. By setting a second area and displaying only the parking lot existing in the area, it is possible to prevent the parking lot from being unnecessarily separated from the event venue I. When the second area is set, the second area is stored in the return traffic congestion avoidance area storage unit 23 in FIG. Then, as shown in FIG. 8, in step 16, the second area is read out, the parking lot in which the second area exists is extracted (step 17), and is displayed on the display (step 19). In FIG. 8, the same processing steps as those in FIG. 3 are designated by the same reference numbers, and the description thereof will be omitted.
When setting this second area, there are conditions to be considered such as the existence of a public transportation station in addition to the distance factor, so it is preferable to set this second area manually. Therefore, also in FIG. 8, when the second area is not set in the event venue (step 7 = N), only the first area is set according to step 11.

The setting of the second area is arbitrary, but for example, as shown in FIGS. 9 to 12, the second areas 201, 204, and 205 have the same width over the entire outer circumference of the first areas 11, 12, and 14, respectively. Can be set with. It may be set to a part of the outer circumference, or its width can be set arbitrarily. The width can be, for example, 100 to 500 m. Furthermore, the outer edge of the second area can be defined by a general road.
In the example of FIG. 13, the outer edge of the second area 206 is substantially equidistant from the event venue I.
Other factors, such as the presence or absence of public transport stations, parking density, and past congestion information, are also taken into account when defining the second area.
As shown in FIG. 10, in the second area, the area existing on the opposite side of the event venue I from the main road 1 is defined as the third area, and the parking lot existing in this third area is given priority. Can guide you.
When there are a plurality of main roads, it is preferable to provide the third area on the main road near the event venue.

The hardware configuration of the guidance device 1 as a computer is shown in FIG.
The arithmetic unit includes a CPU, ROM, and RAM, functions as a guide unit 33, and controls the entire system. The ROM includes a non-volatile memory (not shown) in which a control program or the like for controlling the arithmetic unit is stored. The RAM readablely stores various set values preset by the user via an input device, and provides a working area to the CPU. The control program that controls the arithmetic unit is not limited to the ROM, and may be stored in the RAM, the first storage device, and the second storage device.

The second storage device is a memory device provided in a general-purpose guidance device, and stores data necessary for executing road search and navigation as a map data storage unit 25. More specifically, a road data storage unit 26, a facility data storage unit 27, and a parking lot data storage unit 28 are allotted.
The first storage device is provided with an area storage unit 23 for avoiding traffic congestion on the return route. As the base road congestion avoidance area, the first area is saved and the second area is saved. The first area may be temporarily saved to determine the second area.
It is preferable that the first and second storage devices utilize a part of the area of the memory device provided in the guide device, such as a hard memory and a flash memory.
A part of the RAM of the arithmetic unit can be used for the so-called buffer memory for temporarily storing data.
As shown in FIG. 14, each device constituting the computer is connected by a system bus.
This computer device can communicate with the data center 300 and other external servers (including the server at the event venue) via the communication device 200.

The calculation unit also executes step 11 of FIG. 3 when an event venue in which no data is stored in the return traffic congestion avoidance area storage unit 23 is set as the destination.
More specifically, the center point is calculated by referring to the data of the event venue stored in the facility data storage unit 27. After that, the main road is selected with reference to the road data stored in the road data headquarters 26. Next, referring to the map data stored in the map data storage unit 25, a perpendicular line is drawn from the center point of the event venue to the selected highway, and an isosceles triangle having this perpendicular line as the center line. To draw. Further, with reference to the map data, the outer edge lines 132, 133, 136, 137 are drawn as shown in FIG.

The present invention is not limited to the description of the embodiment of the above invention and its modifications. Various modifications are also included in the present invention as long as those skilled in the art can easily conceive without departing from the scope of claims.
