Description

  The present invention relates to a navigation device and a navigation program, for example, to route guidance when a destination is located on a premises such as a market.

In recent years, the transportation industry has a problem of labor shortage. In particular, the problem is remarkable in the industry related to long-distance transportation.
One of the reasons behind the shortage of human resources in the long-distance transportation industry is the high turnover rate due to interpersonal relationships, as well as the nature of their work.
When a newcomer performs long-distance transportation business, an experienced driver usually performs on-the-job training (OJT) on the newcomer. Generally, on-the-job training is carried out by veterans and newcomers in a single vehicle, from the collection of luggage to transportation and returning to the workplace after transportation. The main contents of OJT are to confirm the place and time to take a break or rest, the road conditions, etc. if the destination is far, and if the destination of luggage is the market, it is peculiar to the market. Due to the existence of the rules, newcomers will also be trained by veterans. This veteran guidance to newcomers is largely based on veteran rules of thumb.
Here, in the case of long-distance transportation, it often takes 24 hours or more from the time of departure to the time of returning to work, depending on the distance traveled. Meanwhile, veterans and newcomers will spend time together in a narrow car, not only during their travel time but also during their rest time. If the veteran and the newcomer are compatible with each other, OJT will also work, but if the compatibility is not good, it will be a great pain for both because they will be restrained in a narrow car for a long time.
Also, there are many areas in the market that are not open to new entrants due to the rules, so even if you get lost on the premises, at the time of a busy time such as auction time, a new driver will be able to unload it to related parties or traders in the market. Can be very difficult to ask. Due to the nature of long-distance transportation, transportation vehicles are large, so if the road is wrong in the market, it may be difficult to change the direction of the transportation vehicle, and it may become impossible to move. The psychological burden felt by new drivers in the market is extremely limited.
Against this background, there are very few new drivers who actually continue to employ even if they apply for a job from a transportation company. In other words, interpersonal relationships within the shipping company and at shipping destinations such as the market are one of the causes of employee turnover, which is the cause of the labor shortage in the operation industry.
And 90% of physical distribution in Japan is by truck. As the current transportation industry is aging and the demand for the transportation industry is increasing, it is urgent to solve the labor shortage problem in the transportation industry.
Another problem facing the transportation industry is the cost of using toll roads and the cost of delay compensation. For example, a driver may use a toll road, such as a highway, if the arrival is unlikely to arrive on time in the market. In this case, the driver often pays the cost of traveling on the expressway, which is a burden to the driver.

Here, a navigation device and a navigation system are disclosed as a method for visualizing the know-how of individual service operations of routes and visited destinations that professional drivers have independently based on their experience (for example, Patent Document 1).
However, the technology described in Patent Document 1 is one-size-fits-all to route delivery, and is a market entrance for arriving at the unloading place at the desired time of vehicle operation and arrival at the unloading place during congestion on the premises. It is not possible to provide timely arrival time, arrival time at each market entrance when passing through multiple markets, arrival time at the unloading place, and departure time at the market exit.

In the RAM, it is possible to secure an area for performing various processes in this embodiment.
The control unit 110 includes a route search unit 111 and an arrival time acquisition unit 112.

The route search unit 111 receives information such as a destination input by the user from the input unit 240 of the user terminal 200 described later, and searches for a route on the premises using the premises information database 121 described later.
The arrival time acquisition unit 112 acquires congestion information from the congestion information database 122 described later, and acquires the arrival time and the like.

The storage unit 120 is composed of a readable / writable storage medium, and a hard disk, SSD, or the like is used.
The storage unit 120 has a premises information database 121, a congestion information database 122, a map information database 123, a market database 124 and other databases.

The premises information database 121 stores information on a route network on the premises such as a market. The route network is represented by a combination of nodes and links. Nodes are intersections, unloading locations, and other nodes on the route network representation. A link is a route section between nodes.
The node data includes information such as a node number, a name, a position coordinate, a node type, the number of connecting links, and a connecting node number.
The node number is a unique number for identifying the node. The name is a name given to the node, such as the name of each unloading place for each item or the name of each wholesale office. The position coordinates represent the position of the node by latitude, longitude, and altitude. The node type is information such as an entrance to the premises, an exit, an entrance gate and an exit gate, a route intersection and a corner, an elevator entrance / exit, an unloading place, a guard room, a receiving office, and a wholesaler office. The number of connecting links is the number of links connecting to the node, and the connecting node number is the number of the node connecting to the node via the link.

The link data includes information such as a link number, a starting node number, an end node number, a link type, a link length, the number of lanes, a road width, lane information, and traffic restrictions such as speed limits.

The passage time is, for example, the time at which the user terminal 200 has passed each of the start node and the end node.
Travel time is the time required to pass between two points. For example, it is the time required for the user terminal 200 to pass between two points of the node, that is, the time required to pass a link, the time required for the user terminal 200 to pass a specific node from the position of the user terminal 200, and the like. The travel time can be calculated by the difference between the passing times of the start node and the end node.
Further, the congestion information database 122 may associate each record with the user terminal 200. This makes it possible to track the movement of the specific user terminal 200 on the premises. Further, the stop time at the node can be calculated from the start node passage time and the end node passage time of the linked records. For example, the time required for unloading can be obtained from the difference between the ending point passage time and the starting point passage time at the node at the unloading place.

Whether or not congestion has occurred can be determined by comparing the travel time in normal times acquired by “dividing the link length by the speed limit on the premises” with the travel time in the premises information database 121. Further, the moving speed of the user terminal 200 is measured by the speed sensor of the current position acquisition unit 280 included in the user terminal 200, which will be described later, and the measured speed is less than or equal to the speed limit of the premises or the general road on which the user terminal 200 is located. Whether or not congestion may occur may be determined based on the above.

Subsequently, the route search unit 111 searches for a route (S3). The route search unit 111 searches for a route starting at the market entrance, passing through the unloading place, and ending at the market exit.
For example, the route search 111 searches the premises information database 121 for the acquired unloading place and acquires the corresponding node.
The route search 111 acquires a connection node corresponding to the acquired node and a link connecting to the node, and searches for a route from a start point to a waypoint and a waypoint to an end point. The route search unit 111 ends the process when the route search is completed.
The starting point of the route guidance is not limited to the entrance, and may be the current position of the user terminal 200, an arbitrary position designated by the user on the map displayed on the display unit 250 of the user terminal 200, or the like. In this case, if the starting point is outside the market, the route from the starting point to the market entrance may use an existing navigation system.

In addition, the route search 111 may calculate the total cost from the start point to the end point when a plurality of routes are searched. The route search 111 can set the route with the lowest cost as the optimum route. The cost can be determined by the required time, the moving distance, and the like.
When the cost is calculated based on the required time, the route search 111 acquires the link length of the link included in the searched route and the speed limit on the premises, and divides the link length by the speed limit to determine the time required to pass the link ( Travel time). By totaling the travel times of all the links included in the route, the total cost of the time related to the route can be calculated.
In addition, the travel time of the congestion information database 122 may be used to add the congestion status to the cost calculation of the required time.

  When a plurality of queues for transportation vehicles are formed on the premises and congestion occurs, the route search 111 may search for which line to line up according to the destination. For example, when the user terminal 200 is mounted on each transportation vehicle, the route search 111 communicates with the user terminal 200 mounted on each transportation vehicle to acquire the position information and the like. Then, the route search 111 acquires each user terminal 200 located on the route to the destination of the user terminal 200 that is the target of route guidance, and selects the user terminal 200 located at the end of the column continuing to the destination. Get the position.

In the case of transportation, it is a situation that should be avoided if the package does not arrive in time for receipt of the package, as it causes problems such as compensation due to delay. For example, when the premises are crowded, a situation in which a time loss occurs, such as arranging in a wrong line and then rearranging in a correct line, which causes a delay, should be avoided. Therefore, when the transportation vehicles form a line in the premises due to congestion, it is important to identify the correct line leading to the unloading place of the user and line up in this line. The navigation device 1 is the last line in the line. You can guide the tail.
In addition, if the destination is beyond the crowded row, the route search 111 may guide the lane without the crowded row when there are a plurality of lanes on the searched route. Good. Further, the route search 111 may guide the lane even if the number of lanes is one as long as it is possible to pass the side of the crowded row due to the width of the lane.

The route searched by the route search 111 is not limited to a plane. For example, the route search 111 can search for a route even when the market consists of multiple floors. More specifically, when the unloading place is on the 2nd floor and the elevator for the transportation vehicle is used for going and the slope is used for returning, the navigation device 1 uses the market entrance to the elevator entrance and the elevator exit to unload place. , The route from the unloading place to the slope entrance and the slope exit to the market exit can be searched by using the premises information database 121. The route search 111 retrieves map data from the map information database 123 based on the searched route. It acquires and transmits the route and map information to the user terminal 200.

The control unit 210 of the user terminal 200 receives the route and map information from the navigation server 100. The control unit 210 displays a map on the display unit 250 and the route on the map based on the received route and map information.
When starting the route guidance, the control unit 210 of the user terminal 200 may output the route guidance from the voice output unit 260 to provide voice guidance.

The navigation device 1 may also display traffic information when displaying the route and the map on the display unit 250. The traffic information is information about one-way traffic, lanes, the number of lanes, the width of a road, or the like.
The long-distance transportation vehicles that enter the market are large, and for example, if a vehicle goes backwards into a one-way street, it is not possible to change the direction of the vehicle in a narrow premises and in a situation where many people come and go. Very difficult. If it becomes necessary to change direction, the driver must run to the guard room and obtain guidance from the guard. In this way, it is necessary for the long-distance transportation vehicles to pass through the premises more accurately than when traveling on ordinary roads. Here, if the one-way traffic is displayed on the map displayed on the user terminal 200, even if the transportation vehicle deviates from the route displayed on the user terminal 200, the navigation is performed. While waiting for the result of the re-search of the route in the device 1, it is possible to prevent the reverse entry into the one-way road.
Similarly, by displaying the dedicated lane, the number of lanes, the road width, etc., the user can grasp traffic information in the premises in advance, and can be more calm when moving within the premises.
In addition, for places such as guard rooms, receiving offices, forklift storage areas that are likely to be needed by users on the premises, icons and colors may be added to the map to make it easier for users to recognize. Good. The user may specify the locations that may be needed on these premises. This is because the necessary information may vary depending on the user's skill level of work.

FIG. 3 is a flowchart showing the flow of acquiring the arrival time.
As mentioned above, in transportation, packages must arrive at their unloading location by the time of receipt. The problem here is that the congestion situation on the premises of the market and outside the premises near the entrance changes depending on the time of day, so in order to arrive at the desired arrival time at the unloading place, consider this congestion situation. The point is that it is necessary to determine the arrival time at the market entrance. As for the arrival time, the arrival time at the market entrance for arriving at the unloading place at that arrival time is acquired from the desired arrival time at the unloading place, taking into consideration the congestion situation on the market premises and near the market entrance. It is a thing.

The control unit 210 of the user terminal 200 acquires a market list from the market database 124 of the navigation server 100 and displays it on the display unit 250.

The arrival time acquisition unit 112 of the navigation server 100 acquires the desired arrival time at the unloading place received from the user terminal 100 as the desired arrival time (S4).
The arrival time acquisition unit 112 searches for a route (S5). The route search unit 111 acquires the market name and the item name received from the user terminal 100, searches for a route starting from the entrance of the market and ends at the unloading place, and the arrival time acquisition unit 112 receives the search result.

The arrival time acquisition unit 112 acquires a link connecting to the end node from the received route search result (S6). The arrival time acquisition unit 112 acquires, from the congestion information database 122, a record that is the same as the acquired link and has an end point node passage time that is before the acquired desired arrival time and is closest to the desired arrival time (S7). The arrival time acquisition unit 112 acquires the origin node passage time from the acquired record.
The arrival time acquisition unit 112 sets the arrival time as the starting point node passing time (S8).
When the acquired start node of the link is the same as the start node (S9: Y), the arrival time acquisition unit 112 ends the process.
When the origin node of the acquired link is not the same as the starting node (S9: N), the arrival time acquisition unit 112 returns to S6 and, from the route search result, the link following the acquired link, that is, the origin of the acquired link. Get the link that connects with the node as the end point and continue the process.
The control unit 110 of the navigation server 100 transmits the desired arrival time to the user terminal 200 as the arrival time.
The control unit 210 of the user terminal 200 receives the arrival time from the navigation server 100 and displays it on the display unit 250 as the market entrance arrival time.

In obtaining the arrival time, you may consider the traffic congestion situation that continues from the market entrance to the outside.
In the present embodiment, the arrival time acquisition unit 112 searches from the end point to the start point, but may search from the start point to the end point. Estimated time of arrival at the unloading location can be provided, such as when you have already arrived at the market entrance.
Further, the end point is not limited to the unloading place, and may be the exit of the market or the like. By searching at the market entrance as the starting point, through the unloading location, and as the market exit as the ending point, the market entrance arrival time for the desired exit time of the market and vice versa, the market exit arrival expected time for the market entrance arrival time Can be provided.

FIG. 4 is a display example of expected times of arrival at the market and arrival at the unloading place. Displays an expected list of arrival times at the market and unloading locations by time zone. Market arrival time is the time of arrival at the market entrance.
The arrival time acquisition unit 112 of the navigation server 100 acquires the result of the route search from the entrance to the unloading place from the route search unit 111, and statistical data regarding the market arrival time, the congestion degree, the unloading place arrival time, and the required time. From the congestion information database 122. The statistics may be real-time, or may be based on the latest week, month, half year, or one year ago, the market opening date, or the like. The arrival time acquisition unit 112 acquires the receipt time from the market database 124 and determines whether the arrival time at the unloading place is within the receipt time.
The control unit 110 of the navigation server 100 transmits the market arrival time, the degree of congestion, the arrival time at the unloading place, the receipt time, and the required time to the user terminal 200, and the control unit 210 of the user terminal 200 receives this. It is displayed on the display unit 250.

As shown in FIG. 4, the display unit 250 displays the market arrival time divided into a certain time and the corresponding unloading place arrival time. The market arrival time may be switched between 30 minutes, 15 minutes, and every 10 minutes so that the user can display the desired unit.
The congestion level represents the congestion status from the entrance to the unloading place at the market arrival time. Expressed as the percentage of travel time that increases compared to travel time in normal times. For example, if the travel time required to reach the unloading place through the entrance is increased by 20% as compared with the travel time in normal times, for example, one of five rectangles is colored. As the congestion rate increases, the number of colored rectangles increases. As a result, the user can grasp the congestion situation from the entrance to the unloading place at a glance. The display of the congestion degree may be expressed by the display of the congestion rate by characters, the shading of colors, or the like, regardless of the above.

Within the receiving time, "○" is displayed if the arrival time at the unloading place is before the receiving time, and "x" is displayed if it is after the receiving time. This allows you to check the final arrival time at the entrance at a glance.
The required time is the time (travel time) required from the entrance to the unloading place.
From the display example, it can be seen that when the arrival time at the entrance is 3:00, the time required to reach the unloading place is 50 minutes. The user can determine the departure time from the luggage collection place, the shipping place, or the like by referring to the display example.
In addition, the arrival time at the exit of the market may be displayed together. Further, the navigation device 1 may calculate the time required for unloading from the congestion information database 122, display it together, or take it into account when acquiring the exit arrival time.

FIG. 5 is a flowchart showing a flow of acquiring the market arrival time, the unloading place arrival time, and the exit arrival time when passing through a plurality of markets.
With regard to long-distance transportation, due to the problem of transportation efficiency, transportation vehicles take a business form of traveling through multiple markets to the final market. Even when passing through multiple markets, the arrival delay of the baggage is naturally a problem, and the arrival time at the market is more complicated because it passes through multiple markets.
In addition, when traveling around multiple markets located in a loop, it is necessary to judge whether to turn on a clockwise route or a counterclockwise route, for example, because there is no significant difference in the transportation distance itself. It is necessary to judge which route should be adopted depending on the traffic conditions in the area. The choice of which route to use is an important decision, because incorrect selection of the route will delay the arrival at the market.
In the case of passing through multiple markets, the point arrival time acquisition is based on the receipt time in the final market, in order to meet the receipt time in the final market, to the market entrance, unloading place, and market exit in each market. Is to get the arrival time of. For example, in the case of traveling in the order of market A, market B, and market C as transportation routes, the navigation device 1 provides the entrance arrival time, the unloading place arrival time, and the exit arrival time of each of the markets A, B, and C. ..

The control unit 210 of the user terminal 200 acquires a market list from the market database 124 of the navigation server 100 and displays it on the display unit 250.
Subsequently, the control unit 210 acquires the selected market name, acquires the items handled in the acquired market from the market database 124 of the navigation server 100, and displays them on the display unit 250.
The user uses the input unit 240 to select an item of parcel to be transported from the items handled in the market displayed on the display unit 250.
The user repeatedly inputs the market name and the item name in the order of going around the market. For example, market A, market B, and market C are input in this order.
The control unit 210 transmits the market name, the item name, the input order, that is, the transportation order to the navigation server 100.

The control unit 110 of the navigation server 100 receives each market name, each item name, and the transportation order from the user terminal 100.
The arrival time acquisition unit 112 acquires the number of transportation destinations from the transportation order received from the user terminal 100 and sets it in the variable COUNT (S11).
The arrival time acquisition unit 112 acquires the market entrance arrival time for the last input market C among the received market names (S12).
The arrival time acquisition unit 112 searches the market database 124 for the received market name and item name for the market C, and acquires the corresponding consignment time as the desired arrival time. When the cargo receiving time has a range, the arrival time acquiring unit 112 sets the final cargo receiving time as the desired arrival time. The user may specify the desired arrival time.

The arrival time acquisition unit 112 receives, from the route search unit 111, a search result of a route starting from the entrance of the market C, passing through the unloading place, and ending at the exit of the market C.

The arrival time acquisition unit 112 acquires, from the congestion information database 122, a record that is the same as the acquired link and has an end point node passing time that is before the acquired desired arrival time and is closest to the desired arrival time. The arrival time acquisition unit 112 acquires the origin node passage time from the acquired record. Here, the passing time of the end point node of the acquired record is the arrival time at the unloading place.
The arrival time acquisition unit 112 repeats the process from the unloading place to the market entrance, which is the starting point, and acquires the starting node passage time at the starting point, that is, the market C entrance arrival time.

When COUNT is the number of destinations (S13: Y), the arrival time acquisition unit 112 acquires the arrival time at the end point (S15). As for the end point arrival time, when the market to be processed is the final transportation destination market, the exit arrival time to the market is acquired according to the route search result based on the unloading place arrival time.
The arrival time acquisition unit 112 sets the acquired arrival time at the unloading place as the end arrival time (S17).
Next, the arrival time acquisition unit 112 acquires from the route search result a link connecting the node at the unloading place as a starting point (S18).
The arrival time acquisition unit 112 acquires, from the congestion information database 122, a record that is the same as the acquired link and has a start node passage time that is after the acquired end point arrival time and is closest to the end point arrival time (S19).
The arrival time acquisition unit 112 acquires the end point node passage time from the acquired record and sets it as the end point arrival time (S20).

  When the end node of the acquired link is the same as the end node of the market exit (S21: Y), the arrival time acquisition unit 112 ends the process. When the end point node is not the same as the end point node (S21: N), the arrival time acquisition unit 112 returns to S18 and continues the process. The arrival time acquisition unit 112 acquires a link that connects from the end point node of the link as a starting point from the route search result, and repeats the above processing until the end point node of the acquired link becomes the same as the end point node. The end point arrival time is the exit arrival time.

Returning to the point arrival point acquisition will be described.
The arrival time acquisition unit 112 decrements COUNT if the COUNT is not the number of destinations (S13: N) (S14).
When COUNT is 0 or less (S16: N), the arrival time acquisition unit 112 ends the process.
When COUNT is larger than 0 (S16: Y), the arrival time acquisition unit 112 returns to S12 and continues the processing.

At that time, although not shown, the arrival time acquisition unit 112 acquires the travel time from the market B to the market C. The arrival time acquisition unit 112 can acquire the travel time from the market B to the market C from an external server or the like. The travel time may include the traffic jam situation at the arrival time of the market C on the road to be used. The arrival time acquisition unit 112 can acquire the congestion information from VICS (registered trademark) or the like. It is possible to provide a more accurate arrival time to each market by taking into consideration the traffic jam condition of the road between each market.
The arrival time acquisition unit 112 calculates a time (market B departure time) obtained by subtracting the travel time between the market B and the market C from the arrival time at the entrance of the market C.

The arrival time acquisition unit 112 returns to S12 and continues the processing.
The arrival time acquisition unit 112 acquires the market name and the item name of the market B, searches the market name and the item name from the market database 124, and acquires the market B departure time as the desired arrival time.
The arrival time acquisition unit 112 receives from the route search unit 111 a search result of a route starting from the entrance of the market B, passing through the unloading place, and ending at the exit of the market.
The arrival time acquisition unit 112 acquires a link connecting the exit node of the market B as an end point from the search result. The arrival time acquisition unit 112 acquires, from the congestion information database 122, a record that is the same as the acquired link and has an end point node passing time that is before the acquired desired arrival time and is closest to the desired arrival time. The arrival time acquisition unit 112 acquires the origin node passage time from the acquired record. Here, the end point node passing time of the acquired record becomes the exit arrival time.

In this way, the arrival time acquisition unit 112 traces back from the end point to the start point, and the end point node passage time (market B unloading place arrival time) and the start point node passage at the start point in the link having the node of the unloading place as the end point node. Get the time (market B entrance arrival time).
When the difference between the market B departure time and the market B exit arrival time is large, the arrival time acquisition unit 112 sets the market B exit arrival time as the market B departure time, and the travel times of the markets B and C, and The entrance arrival time of the market C, the arrival time of the unloading place, and the exit arrival time may be recalculated. At this time, the arrival time at the unloading place is calculated to be within the receiving time.

After that, the arrival time acquisition unit 112 continues the process until COUNT becomes 0 or less (S16: N).
The arrival time acquisition unit 112 acquires the travel time of the market B and the market A and calculates the market A departure time. As in the case of the market B, the arrival time acquisition unit 112 determines the arrival time of the origin node at the start node in the market A (the arrival time of the market A) and the arrival time at the end node of the link whose destination node is the unloading place (the arrival time at the end node). Market A unloading place arrival time) and end point node passing time (market A exit arrival time) at the end point node are acquired.
Also in this case, when the difference between the departure time of the market A and the arrival time of the exit of the market A is large, the arrival time acquisition unit 112 sets the arrival time of the exit of the market A as the departure time of the market A and the succeeding market B and the market. The entrance arrival time, the unloading place arrival time, and the exit arrival time at C may be recalculated. At this time, the arrival time at each unloading place is calculated to be within the range of each receiving time.
The acquisition of the arrival time at the market entrance may take into consideration the traffic jam situation that continues from the entrance to the market to the outside. Further, the arrival time acquisition unit 112 may calculate the time required for unloading from the congestion information database 122 and take this into consideration when acquiring each arrival time.
