Embodiments of the present invention will be described with reference to the accompanying drawings. Where possible, the same parts are given the same reference numerals and redundant explanations will be omitted.

FIG. 1 is a block diagram showing the functional configuration of a route guidance device 100 according to this embodiment. This route guidance device 100 periodically acquires time information and position information from the in-vehicle equipment 201 of each of the other vehicles 200 that are moving objects that are not subject to route guidance, and based on the position information etc. The evaluation value of the advertisement 200a mounted on the vehicle 200 is calculated and stored. The route guidance device 100 derives a route with high advertising effectiveness based on positions with high advertising evaluation values, and notifies the route to the vehicle 200 that has requested route guidance. Note that there are a plurality of automobiles 200, and one or more other automobiles 200 that are not route guidance targets transmit information for calculating an advertisement evaluation value to the route guidance device 100. Route guidance device 100 calculates and holds an advertisement evaluation value. The route guidance device 100 acquires location information and the like from the vehicle 200 that has requested route guidance, derives a route with high advertising effectiveness based on the advertisement evaluation value, and notifies the vehicle 200 of the route. In the following description, unless otherwise specified, the vehicle 200 is the vehicle that has requested route guidance.

The automobile 200 includes an on-vehicle device 201, a GPS device 202, a vehicle speed sensor 203, and a route display section 204. The in-vehicle device 201 acquires the position information measured by the GPS device 202 and the vehicle speed measured by the vehicle speed sensor 203, and periodically transmits them to the route guidance device 100. The route display section 204 is a section that receives the route transmitted from the route guidance device 100 and displays it. In this embodiment, the route display section 204 is assumed to be realized by a car navigation system installed in the automobile 200, but it may also be realized by a smartphone/portable terminal and its navigation application. When using a smartphone or the like, information on the current location, destination, etc. is provided by the smartphone's GPS function and its communication function. Further, the automobile 200 has an advertisement 200a placed on its side. Advertisement 200a may be placed on the rear window of automobile 200.

This route guidance device 100 includes a control section 101, a storage section 101x, an evaluation section 102 (calculation section), a management section 103, and a route derivation section 104 (route determination section, notification section, storage section). .

The control unit 101 is a part that generates information in a database held by the storage unit 101x based on the position information and time information transmitted from the in-vehicle device 201, and stores the information in the corresponding database.

The storage unit 101x stores a driving state management DB 101a, a traffic jam information DB 101b, a population etc. information DB 101c, and a weather information DB 101d.

The driving state management DB 101a is a database that stores the ID, time, location information, and vehicle speed of the vehicle 200, which are periodically transmitted from the on-vehicle device 201, in association with each other. In addition, the control unit 101 calculates the traveling direction of the vehicle 200 based on the amount of change in the position information of the vehicle 200 (for example, 0° to 359° where true north is 0° and true south is 180°). °) and is stored in the running state management DB 101a. The driving state management DB 101a is a database for providing the evaluation unit 102 with position information, vehicle speed, and heading information.

The traffic jam information DB 101b is a database that stores traffic volume and traffic jam information on each road. The traffic volume indicates the number of vehicles passing on each road per predetermined time. The traffic congestion information is information indicating the degree of congestion of vehicles passing on each road, and indicates the degree of congestion in multiple stages depending on the speed of the vehicles. Note that roads are generally passable in both directions, and the traffic volume and congestion information indicates the number of vehicles passing in both directions and the degree of congestion. The control unit 101 derives traffic volume and congestion information for the point and its surrounding roads based on the location information and time information of the vehicle 200 obtained from the driving state management DB 101a, and provides the information to the evaluation unit 102.

The population etc. information DB 101c is a database that stores population information for each predetermined section divided into mesh shapes. Population information includes the number of people present in a specific area and time, as well as additional information such as gender and age. Further, the population information may be based on statistical information compiled in advance, but may also be based on information calculated by processing information based on location registration of a mobile terminal or the like. Based on the location information and time information of the vehicle 200 obtained from the driving state management DB 101a, the control unit 101 derives information such as the population, gender, age, etc. of the point and its surroundings, and if possible, the time period. and provides it to the evaluation unit 102.

The weather information DB 101d is information indicating weather such as clear skies, rainy skies, and cloudy skies. Weather information is shown for each specific area and time of day. This weather information is based on information obtained in advance from a weather site or the like. Based on the location information and time information of the vehicle 200 obtained from the driving state management DB 101a, the control unit 101 derives weather information for the location, its surroundings, and the time period, and provides the information to the evaluation unit 102.

The evaluation unit 102 is a part that evaluates advertisements installed in the automobile 200 based on various information stored in the driving state management DB 101a, the traffic jam information DB 101b, the population etc. information DB 101c, and the weather information DB 101d. The evaluation unit 102 evaluates the advertisement mounted on the car 200 based on the position of the car 200, speed, time zone, population information at the position, traffic congestion information (degree of congestion) at the position, and weather at the position at the advertisement evaluation point. Calculate the evaluation value of effectiveness. In this embodiment, the advertisement evaluation point is a predetermined intersection, but is not limited to this, and may be an arbitrarily determined position. The advertisement evaluation value is calculated based on how many people have seen the advertisement.

For example, the advertisement evaluation value is calculated based on the following formula.

Evaluation value of advertising effectiveness for surrounding pedestrians = Surrounding situation x Vehicle situation
= (Surrounding population x Surrounding weather coefficient x Day/night coefficient) x Vehicle speed coefficient Evaluation value of advertising effectiveness for drivers around the area = Surrounding situation x Traffic volume x Advertising shape x (Congestion situation in the forward direction + Traffic congestion situation in the opposite direction)
= (surrounding weather coefficient x day/night coefficient) x traffic volume x advertisement shape factor x traffic congestion level coefficient (progress) x traffic congestion level coefficient (oncoming)
The above-mentioned vehicle speed coefficient and the like are information acquired from the driving state management DB 101a, and are information based on the vehicle speed of a vehicle 200 different from the vehicle 200 being routed.

Note that the method of calculating the advertisement evaluation value for each advertisement evaluation point is not limited to the above. For example, the evaluation unit 102 calculates the advertisement evaluation value based on position information, vehicle speed, etc. obtained from the plurality of cars 200, but the information from the cars 200 is not necessarily essential. The evaluation unit 102 may periodically acquire population information, traffic congestion information, etc. of the advertisement evaluation point, and calculate an advertisement evaluation value of the advertisement evaluation point based on this information. Further, an advertisement evaluation value may be set in advance for each advertisement evaluation point.

The evaluation unit 102 stores the calculated advertisement evaluation value in the location-specific advertisement effect DB 104a for each advertisement evaluation location.

In this embodiment, the evaluation unit 102 calculates an evaluation value for each intersection that is set in advance as an advertisement evaluation point. This advertisement evaluation point is determined in advance and stored in, for example, an intersection DB (not shown). Note that road information stored in a road information DB 104b, which will be described later, may be used. The evaluation unit 102 outputs the ID of the car 200 and the advertisement type, as well as its evaluation value, to the management unit 103 and the location-specific advertisement effect DB 104a.

The management unit 103 is a part that holds a vehicle DB 103a and an advertisement DB 103b that store evaluation values calculated by the evaluation unit 102. The vehicle DB 103a stores the ID of the vehicle 200 to be evaluated, the advertisement type, the evaluated advertisement evaluation point (intersection), and its evaluation value. Note that information on advertisement evaluation points (intersections) is not essential. Information stored in the location-based advertising effect DB 104a may be used. Advertisement DB 103b stores various information regarding advertisements carried by automobile 200. Various types of information include information about advertisers, information about the content of advertisements, information about the format of advertisements (for example, the format and size of wrap advertisements, sticker advertisements, etc.), and information about advertisement contracts (posting period, budget, etc.). be.

The route deriving unit 104 receives the current location of the vehicle 200 that has requested route guidance and the destination (end point) specified by the driver of the vehicle 200 from the vehicle 200 (in-vehicle device 201), and based on this information, normally This is the part that derives the route. This route derivation processing is similar to known navigation processing, and uses, for example, the route search DB 104c. In this embodiment, the route derivation unit 104 further includes a location-by-point advertising effect DB 104a and a road information DB 104b, and uses these to derive the second route.

That is, the route derivation unit 104 selects an advertisement evaluation point based on the road information stored in the road information DB 104b and the advertisement evaluation value for each intersection stored in the advertising effect DB 104a by point, and applies the selected advertisement evaluation point. A second route passing through the point is derived using the route search DB 104c. This derivation method will be described later.

The location-based advertising effectiveness DB 104a stores advertising evaluation values indicating the advertising effectiveness evaluated by the evaluation unit 102 for each of the identification information assigned to each region divided into a mesh shape and each advertising evaluation point included in each region. do. The road information DB 104b stores road information indicating advertisement evaluation points (for example, intersection IDs) for each identification information indicating each area divided into a mesh shape. The route search DB 104c is a database for route derivation. Since this is a well-known database, its details will be omitted.

A specific example is shown in FIGS. 2 and 3. As shown in FIGS. 2 and 3, the location-based advertising effectiveness DB 104a stores advertising evaluation values for each advertising evaluation location. The road information DB 104b indicates, for each piece of identification information indicating a region, advertisement evaluation points included in that region. In the figure, ID is shown for convenience, but advertisement evaluation points may be specified using information such as latitude and longitude.

The route deriving unit 104 notifies the automobile 200 that has requested route guidance that there is an advertising cost consideration route as a second route, and also notifies the normal route and/or the second route in accordance with instructions from the driver. Note that in this embodiment, the route deriving unit 104 derives the normal route, but the normal route may be derived in the automobile 200 and the route deriving unit 104 may derive only the second route. In that case, the route derivation unit 104 obtains information indicating the normal route (for example, intersection information, direction of travel, right/left turn direction, etc.) from the automobile 200, and derives the second route based on the information.

The operation of the route guidance device 100 configured in this way will be explained. 4 to 7 are flowcharts showing the operation of the route guidance device 100 of this embodiment. FIG. 4 is a flowchart showing the first half of the basic operation of the route guidance device 100.

The route derivation unit 104 receives a route guidance application activation signal from the automobile 200 (S101). This route guidance application is a program that operates on the in-vehicle device 201, and its activation signal includes a route guidance request. The route derivation unit 104 determines whether the route search conditions have been initialized or changed (S102). If it is determined that there is an initial setting or setting change here, route search conditions are set (S103). This initial setting or setting change refers to the initial setting or setting change of search conditions for deriving the normal route and the second route. The application activation signal includes a search condition, and the route deriving unit 104 can determine whether or not there has been a change based on the search condition and the already set search condition. If the search conditions have not been set, the search conditions indicated by the activation signal are set to initial values.

The route derivation unit 104 determines whether a destination needs to be set based on the destination of the automobile 200 (S104). This destination is included in the application activation signal or the destination signal separately received from the vehicle 200, and is information set by the driver of the vehicle 200.

Further, the route derivation unit 104 receives purpose information of the automobile 200 and determines the purpose (S105). The driving purpose is included in the application activation signal or the driving purpose signal separately received from the car 200, and is information specified by the driver of the car 200. The on-vehicle device 201 and route display unit 204 of the automobile 200 allow the driver to select a destination and transmit the selected information to the route guidance device 100.

Here, if the route derivation unit 104 determines that the vehicle is traveling for the purpose of transportation, the route derivation unit 104 acquires position information from the automobile 200 (S106). The route derivation unit 104 uses the position information as a starting point and derives a route for the automobile 200 based on the starting point and the destination acquired in advance (S107).

The route derivation unit 104 transmits identification information (mesh code, etc.) of the area where the derived route exists (area divided by mesh) and its surrounding area (for example, an adjacent area) to the road information DB 104b, and determines the advertisement evaluation point. information (intersection ID, etc.) indicating the intersection is acquired (S108). The route derivation unit 104 uses the route search DB 104c to perform the route derivation process in step S107, and also acquires the identification information of the area where the derived route exists from the map data held by the route search DB 104c. In the map data, identification information is given to each area divided into a mesh pattern, and the area is maintained so that the area can be identified.

FIG. 5 is a flowchart showing the second half of the basic operation of the route guidance device 100.

In FIG. 5, when the route derivation unit 104 acquires the information of the advertisement evaluation point as in step S108, the route derivation unit 104 acquires the advertisement evaluation value of the advertisement evaluation point from the advertisement effect DB 104a by location (S109). Then, the route deriving unit 104 derives a route with high advertising effectiveness based on the advertising evaluation value for each advertising evaluation point (S110). For example, the route derivation unit 104 selects the top n advertisement evaluation points with the highest advertisement evaluation values, and derives a route passing through the advertisement evaluation points. At that time, a route is derived based on the route search conditions. Route search conditions include travel time, travel distance, advertising effectiveness, etc. For example, the travel time in the route search condition indicates the upper limit of the additional time required from the normal route derived in step S107. Similarly, the mileage indicates the upper limit of the additional distance taken from the normal route. Advertising effectiveness indicates the lower limit of advertising effectiveness. That is, the advertising effect in the search condition indicates information that provides the minimum advertising effect. Here, the advertisement fee that the driver can obtain is shown as the advertisement effect.

The route derivation unit 104 determines the route with the highest advertising effect among the routes that satisfy the route search conditions as the second route, but a plurality of routes may be included in the second route. The route derivation unit 104 also calculates the total value (normal total value) of advertisement evaluation values at advertisement evaluation points on the normal route, and calculates the total value (normal total value) of advertisement evaluation values at advertisement evaluation points forming the second route. The notification process may be performed when the second route total value) is larger than the normal total value. Conversely, if the total value of the second route is smaller than the normal total value, the notification process may not be performed, or a notification to that effect may be performed.

The route deriving unit 104 transmits a route candidate including the normal route and the second route to the automobile 200, and causes the route display unit 204 to display the route candidate or a message to that effect (S111). The route candidates include the normal route derived in step S107 and the second route derived in step S110.

In the automobile 200, the driver selects one route from the provided route candidates while looking at the route display section 204. The route display unit 204 acquires the selected route from the route guidance device 100 and stores it (S112). The in-vehicle device 201 and the route display unit 204 provide route guidance for the automobile 200 to the driver based on the selected route and the position of the automobile 200. Note that this route guidance processing may be performed within the automobile 200, or may be performed while sequentially exchanging position information in the route guidance device 100.

The route derivation unit 104 acquires position information of the automobile 200 at any time (S113). When the route derivation unit 104 determines that the automobile 200 has deviated from the selected route (S114: Y), the process returns to step S106 and re-derives the second route. The route deriving unit 104 also determines whether a more effective route has been found based on the position information of the vehicle 200 (S115). For example, such processing may occur when there is an advertisement evaluation point with higher advertising effectiveness due to the effect evaluation value of the location-based advertising effectiveness DB 104a being updated. Note that the evaluation unit 102 periodically refers to the storage unit 101x, calculates an evaluation value of advertising effectiveness at each advertising evaluation point, and updates the advertising effectiveness DB 104a by location. If there is a more effective route, the process returns to step S106 and the route is re-derived.

Then, the route deriving unit 104 repeatedly processes S113 to S115 until the automobile 200 finishes traveling (S116).

Next, the process when the destination is not set in process S104 of FIG. 4 will be described. FIG. 6 is a flowchart showing the processing.

The route derivation unit 104 acquires current position information of the automobile 200 (S201). Then, the route derivation unit 104 acquires advertisement evaluation points around the location information from the road information DB 104b (S202). For example, the route derivation unit 104 acquires advertisement evaluation points included in each of the area including the location information and the area adjacent to the area. That is, the advertisement evaluation point corresponding to the identification information assigned to each region is acquired.

The route derivation unit 104 refers to the advertisement effect DB 104a by location, selects the advertisement evaluation points with the highest n advertisement evaluation values from the acquired advertisement evaluation points, and notifies the vehicle 200 of the advertisement evaluation points ( S203). Note that the order of the process of acquiring advertisement evaluation points in S202 and the process of referring to the location-specific advertisement effect DB 104b does not matter. That is, the advertising effectiveness DB 104b by location may be referred to to obtain the m-th top advertising evaluation point, and from there, surrounding advertising evaluation points may be obtained.

The route derivation unit 104 constantly acquires the location information of the vehicle 200 (S204), and each time the location information changes, it notifies the vehicle 200 of the advertisement evaluation point (S203, S205). The route display section 204 in the automobile 200 displays the advertisement evaluation value of the advertisement evaluation point. Note that only advertisement evaluation points with advertisement evaluation values greater than or equal to a predetermined value may be notified.

When the automobile 200 finishes traveling, the route deriving unit 104 receives the start-off signal transmitted from the automobile 200, and ends the process (S205). Note that the route derivation unit 104 may derive a route between the current position of the automobile 200 and an advertisement evaluation point with a high advertisement evaluation value, and notify the automobile 200 of the route.

Next, a description will be given of a process performed in step S105 when the purpose is to earn advertising fees. FIG. 7 is a flowchart showing the processing. It is assumed that the driver of the automobile 200 is driving for the purpose of earning advertising fees, not for traveling to a specific destination.

When the route derivation unit 104 receives information indicating that the driving purpose is to earn advertising fees from the automobile 200, it sets advertising fee earning conditions (S301). The route derivation unit 104 also acquires position information of the automobile 200 (S302). Then, the route derivation unit 104 acquires advertisement evaluation points around the location information from the road information DB 104b, and based on this, from the advertisement effectiveness DB 104a by location, the route derivation unit 104 acquires the advertisement evaluation points around the current location information and the surrounding advertisement An advertisement evaluation value is acquired (S303). For example, the route derivation unit 104 acquires advertisement evaluation points and advertisement evaluation values included in each of the area where the automobile 200 is located and the adjacent area adjacent to the area. In addition, in the process of S303, similarly to the processes of S202 and S203, the processing order of the advertisement evaluation point acquisition process and the process of referencing the location-based advertisement effect DB 104a (acquisition of the top mth ranking) does not matter.

The route derivation unit 104 derives a route based on the advertising effectiveness condition among the route search conditions (S304). For example, the advertisement evaluation values to be acquired are set to the top m, etc., and a route that provides an advertisement evaluation value equal to or greater than a predetermined value is derived. In this embodiment, advertising effectiveness can be converted into monetary value. Therefore, the route deriving unit 104 derives a route that allows a predetermined fee to be obtained as an advertising fee. The route derivation unit 104 transmits the derived route to the vehicle 200 and displays it on the route display unit 204 (S305).

The route derivation unit 104 acquires position information of the automobile 200 at any time (S306). If the route derivation unit 104 determines that the automobile 200 has deviated from the selected route (S307: Y), the process returns to step S304 and re-derives the route. Furthermore, the route derivation unit 104 determines whether a more effective route has been found based on the position information of the automobile 200 (S308). If there is a more effective route, the process returns to step S304 and the route is re-derived. Then, the route derivation unit 104 repeatedly processes S304 to S308 until the vehicle 200 finishes traveling (S309).

As described above, the route guidance device 100 can derive a second route with high advertising effectiveness based on the location information of the automobile 200, the destination, and the search conditions for the second route. 8 to 10 are explanatory diagrams of the process when deriving the second route. FIG. 8 shows a diagram in which the automobile 200 starts from a starting point S and aims at an ending point E (destination). As described above, the end point E is the destination, and is information set by the driver of the automobile 200. The route deriving unit 104 derives a normal route R using the starting point S and the ending point E.

FIG. 9 is a diagram showing advertisement evaluation points around the normal route R. In FIG. 9, the map is divided into meshes. Advertisement evaluation points K1 to k6 are shown in each region.

For example, the advertisement evaluation point K2 is a point that exists within the area M1 where the normal route R exists. Further, the advertisement evaluation point K3 is a point that exists within the region M2 around the region M3 where the normal route R exists. The same applies to advertisement evaluation points K1, K4 to K6.

The route derivation unit 104 selects an advertisement evaluation point with a high advertisement evaluation value from among these advertisement evaluation points K1 to K7. In this embodiment, K1, K3, K4, K5, and K6 are selected as advertisement evaluation points with high advertisement evaluation values, and a route passing through these advertisement evaluation points is derived. FIG. 10 is a diagram showing a specific example thereof, in which the route derivation unit 104 derives a route R2 as a second route in addition to the normal route R, and transmits this information to the automobile 200.

In the example of FIG. 10, only one second route is derived, but the second route is not limited to this. For example, the route derivation unit 104 may derive a plurality of second routes by changing the combination of advertisement evaluation points K1 to K7, and select one or more routes with high advertisement evaluation values from among them. For example, the route derivation unit 104 may derive a route that passes through all advertisement evaluation points, and may derive a route that passes through the advertisement evaluation point with the highest advertisement evaluation value or the top n advertisement evaluation points. The route derivation unit 104 may also compare the distance or transit time of the normal route R and narrow down the second route so that it falls within the conditions.

FIG. 11 is a diagram showing an example of a screen displayed on the route display section 204 of the automobile 200. As shown in the figure, when the route guidance device 100 is able to derive the second route, a screen for notification of reroute taking into account advertising expenses is displayed. When the driver selects a new route here, the route display section 204 displays a second route, which is not the normal route (generally the shortest route), and which passes through advertising evaluation points with high advertising effectiveness. For example, the route is displayed in the format shown in FIG.

FIG. 12 is a diagram schematically showing a route search condition setting screen. This figure shows an example of a screen displayed on the route display section 204. As shown in the figure, in addition to the normal route search conditions, the driver can select route search conditions that allow him to earn advertising fees. As shown in the figure, the driver can set travel time conditions, travel distance conditions, and advertising effectiveness conditions, and the in-vehicle device 201 can notify the route guidance device 100 of these advertising effectiveness conditions.

Next, the effects of the route guidance device 100 of this embodiment will be explained. The route guidance device 100 in this embodiment provides a location-by-point advertisement effect DB 104a that stores advertisement evaluation values of advertisement evaluation points, and a route passing through the advertisement evaluation points to the driver (user) of the automobile 200 based on the advertisement evaluation values. and a route deriving unit 104 that notifies the user.

With this configuration, the driver of the automobile 200 can be notified of the route passing through the advertisement evaluation point, and the driver can know the route. Therefore, drivers can obtain higher advertising fees by passing through advertising effect points as needed.

More specifically, in the route guidance device 100, the route derivation unit 104 provides a second route that passes through advertisement evaluation points around the normal route (first route) derived based on the destination input by the driver of the automobile 200. Derive the route. Then, the route derivation unit 104 performs a notification process of the second route.

With this configuration, it is possible to move along the second route that passes around the first route. Therefore, the driver can earn more advertising fees without having to make a major detour.

The route derivation unit 104 also extracts advertisement evaluation points around the first route, and sets a route passing through the advertisement evaluation points as a second route. Thereby, route derivation processing can be performed based on advertisement evaluation points, and the algorithm for the route derivation processing can be simplified.

More specifically, the route derivation unit 104 determines a first route based on the specified end point, and extracts one or more advertisement evaluation points from a predetermined area including the first route and an adjacent area adjacent to the predetermined area. Then, a second route leading to the end point via the advertisement evaluation point is determined.

Furthermore, when a plurality of advertisement evaluation points are extracted, the route derivation unit 104 extracts one or more advertisement evaluation points that satisfy a predetermined condition. For example, by narrowing down the search to advertising evaluation points with high advertising evaluation values, routes with high advertising effectiveness can be derived.

In addition, the route derivation unit 104 performs notification processing when the total value of second advertisement evaluation values of advertisement evaluation points on the second route is larger than the total value of the first advertisement evaluation values of advertisement evaluation values on the first route. I do.

Thereby, when the advertisement evaluation value of the second route is small, it is possible to prevent unnecessary notification processing from being performed.
Furthermore, in the route guidance device 100, the route derivation unit 104 notifies the automobile 200 of advertisement evaluation points that satisfy a predetermined condition. For example, the route derivation unit 104 may select and notify advertisement evaluation points with high advertisement evaluation values from advertisement evaluation points not included in the second route, as well as the second route.
This allows the user to be provided with information for selecting another route.

The route guidance device 100 further includes an evaluation unit 102 that calculates an advertisement evaluation value for each advertisement evaluation point based on the movement status of each other vehicle 200 that is not a route guidance target.
