Description

  The present invention relates to a movement guidance device, a movement guidance system, and a computer program for performing a movement guidance of a moving object.

  2. Description of the Related Art In recent years, a vehicle is often equipped with a navigation device that provides travel guidance for a vehicle and enables a driver to easily reach a desired destination. Here, the navigation device means that the current position of the vehicle is detected by a GPS receiver or the like, and map information corresponding to the current position is obtained through a recording medium such as a DVD-ROM or HDD or a network and displayed on a liquid crystal monitor. It is a device that can do. Further, the navigation device has a route search function for searching for an optimal route from a departure place (for example, the current position of the own vehicle) to a set destination when a desired destination is set. It also has a traveling guidance function of performing traveling guidance according to a route (guide route). In recent years, some mobile phones, smartphones, tablet terminals, personal computers, and the like have functions similar to those of the above-described navigation device (hereinafter, referred to as a movement guide device including the navigation device).

That is, with a travel guidance device having map information that does not include a newly constructed road, appropriate travel guidance may not be performed when traveling around the newly constructed road. In particular, in the case of a smartphone, a tablet terminal, or the like, there is a case where the map information itself is not provided on the movement guide device side.

  Therefore, in recent years, it has been performed to acquire, from a server device, guidance information necessary for providing a vehicle or the like with a moving body. For example, Japanese Patent Application Laid-Open No. 2001-27539 discloses that, when performing a traveling guide of a vehicle based on a guidance route searched by a center route search, a navigation device guides a predetermined distance from a current position of the vehicle along the guidance route. There has been proposed a technology for sequentially requesting information from a server device and performing vehicle travel guidance using guidance information distributed from the server device.

  Further, the communication module 38 is a communication for receiving various information such as map update information, route information, travel guidance information, and traffic information transmitted from the server device 4, a VICS (registered trademark) center, a probe center, or the like. The device is, for example, a mobile phone or a DCM.

  Subsequently, in the movement guidance system 2 having the above configuration, a movement guidance processing program executed by the navigation device 1 and the server device 4 will be described with reference to FIGS. 4 and 5 are flowcharts of the movement guidance processing program according to the present embodiment. Here, the movement guidance processing program is executed after the ACC power supply (accessory power supply) of the vehicle is turned on, that is, after the navigation device 1 is activated, to search for a route from the departure place to the destination and to follow the guide route. This is a program that provides travel guidance. 4 and 5 are stored in a RAM or a ROM provided in the navigation device 1 or the server device 4, and are executed by the CPU 21 or the CPU 51.

  First, a movement guidance processing program executed by the CPU 51 of the navigation device 1 will be described with reference to FIGS. In step (hereinafter abbreviated as S) 1, the CPU 51 sets a destination of the route. The destination is basically set based on the user's operation (for example, the operation of reading a registered point, the operation of searching for and selecting a facility) received by the operation unit 34.

  Thereafter, in S2, the CPU 51 transmits a route search request for requesting a search for a route from the departure place to the destination to the server device 4. Here, the route search request includes a terminal ID that specifies the navigation device 1 that has transmitted the route search request, a departure place (for example, the current position of the vehicle), which is a search condition for the route search, and an object set in S1. And information for identifying the ground.

  Thereafter, in S3, the CPU 51 receives the search route information transmitted from the server device 4 in response to the route search request. Here, the search route information received in S3 is based on the departure point searched by the server device 4 using the device side map information 25 which is the latest version of map information based on the route search request transmitted in S2. This is information (for example, a link string included in the center route) that specifies a recommended route to the ground (hereinafter, referred to as a center route).

  Subsequently, in S4, the CPU 51 sets the center route received in S3 as a guide route to which the navigation device 1 performs the travel guidance of the vehicle. However, it is not always necessary to set the center route itself as the guide route, and a route obtained by partially changing the center route may be used as the guide route.

  Next, in S5, the CPU 51 requests the travel guidance information 26 necessary for guidance output within a predetermined distance from the current position of the vehicle along the guidance route. The request for the travel guide information 26 includes a terminal ID for specifying the navigation device 1 that has transmitted the request for the travel guide information, and information (for example, coordinates and link ID) for specifying a section for which the travel guide information is requested. It is included. In the present embodiment, as shown in FIG. 6, the travel guidance information 26 required for guidance output in a section of 10 km along the guidance route 61 from the current position of the vehicle is requested. The section for which the travel guidance information is requested may be 3 km or 5 km. Further, since the processing after S5 is repeatedly executed at predetermined intervals until the vehicle arrives at the destination, it is necessary to sequentially request the traveling guidance information along the guidance route set in the navigation device 1 from the departure point side. It becomes.

  Thereafter, in S6, the CPU 51 receives the travel guide information 26 transmitted from the server device 4 in response to the request for the travel guide information 26 in S5. The travel guidance information 26 includes a phrase of voice guidance output in the vehicle, image data output in the vehicle, an intersection name of the guidance intersection, a position coordinate of the guidance intersection, an entrance link ID and an exit link ID at the guidance intersection, and the like. Contains identifying information. However, in step S6, the content of the guide phrase (that is, text data or voice data) is not received, but is received using identification information (for example, ID) shared between the server device 4 and the navigation device 1. Similarly, image data is received by identification information (for example, ID).

  For example, in the example shown in FIG. 6, a guide route 61 within 10 km from the current position of the vehicle toward the destination includes a congestion section 62, and includes intersections 63 and 64 as guidance intersections. Therefore, the travel guidance information 26 for guiding the congested section 62, the travel guidance information 26 for performing the travel guidance at the intersection 63, and the travel guidance information 26 for performing the travel guidance at the intersection 64 are respectively acquired. Become. In addition to information on traffic congestion sections and guidance intersections, information for performing, for example, lane regulation guidance, railroad crossing guidance, lane change guidance, merging guidance, etc. is also included in the traveling guidance information 26 as necessary. It is.

  Thereafter, in S7, the CPU 51 executes a later-described DB update process (FIG. 7). Note that the DB update process is a process of updating the distribution information DB 46 that stores the travel guidance information 26 distributed from the server device 4 in accordance with the attribute assigned to the travel guidance information 26.

  Next, before describing S8 and subsequent steps, a movement guidance processing program executed by the CPU 21 of the server device 4 in parallel with S1 to S7 will be described. Note that the following processes of S31 to S33 and S34 to S45 are started at the timing of receiving the corresponding information from the navigation device 1, and are executed in parallel with each other. Therefore, the execution order of each step is not always performed in ascending order of step numbers.

  First, in S31, the CPU 21 receives a route search request transmitted from the navigation device 1. The route search request includes a terminal ID for specifying the navigation device 1 that has transmitted the route search request, a departure place (for example, the current position of the vehicle) which is a search condition for the route search, and a destination set in S1. And information for specifying

  Next, in S32, the CPU 21 performs a route search process from the departure place to the destination using the route search request received in S31 and the device-side map information 25 included in the server device 4, and performs a search from the departure place to the destination. Identify the recommended route (center route) to the ground. For example, a known Dijkstra method is used to search for the center route, and the route with the smallest total cost value is set as the center route.

  Subsequently, in S33, the CPU 21 transmits search route information (for example, a link string included in the center route) for specifying the center route specified in S32 to the navigation device 1 that has transmitted the route search request. As a result, the center route is set as the guide route in the navigation device 1.

  Thereafter, in S34, the CPU 21 receives a request for the traveling guidance information 26 transmitted from the navigation device 1 after the guidance route is set. The request for the travel guide information 26 includes a terminal ID for specifying the navigation device 1 that has transmitted the request for the travel guide information and information (for example, coordinates and link ID) for specifying a section for which the travel guide information is requested. ) And is included.

  Next, in S35, the CPU 21 creates a link sequence using the device-side map information 25 for the section where the travel guidance information has been requested.

  Subsequently, in S36, the CPU 21 determines whether guidance is necessary for each link included in the link string created in S35. Specifically, when the end point of the link corresponds to a guidance intersection (an intersection where the guidance route does not pass in the direction of the road, or a special intersection even when the route passes in the direction of the road), and a congested section in the link If there is an event to be guided to the occupant, such as a lane regulation, a level crossing, a lane change section, or a merging section, it is determined that guidance is necessary.

  When it is determined that the link corresponds to a link requiring guidance (S36: YES), the process proceeds to S37. On the other hand, when it is determined that the link does not require guidance (S36: NO), the link to be processed is switched. Then, after the processing of S36 to S43 is completed for all the links included in the link string created in S35, the process proceeds to S44.

  In S37, the CPU 21 reads, for the link to be processed, the travel guidance information created in S39 and S42, which will be described later, in the past processing for the vehicle that has requested the travel guidance information. Note that the past process is a process executed within the same traveling, that is, after the ACC power (accessory power supply) of the vehicle that has requested the traveling guidance information is turned on. The travel guidance information created in the server device 4 in the past is stored in the flash memory 24 or the like.

  Next, in S38, the CPU 21 determines whether or not the travel guidance information has been read in S37.

  If it is determined in S37 that the driving guidance information has not been read (S38: YES), that is, the driving guidance information relating to the link to be processed in the same driving has been transmitted to the vehicle that has requested the driving guidance information in the past. If not, the process proceeds to S39.

  In S39, the CPU 21 provides a vehicle guidance such as a voice guidance phrase output in the vehicle, image data output in the vehicle, an intersection name of the guidance intersection, a position coordinate of the guidance intersection, an entrance link ID and an exit link ID at the guidance intersection. Various types of information required for the vehicle are acquired from the device-side map information 25 or an external server, and are generated as travel guide information to be distributed to the navigation device 1. The phrase and image data for voice guidance are obtained by identification information (for example, ID).

  Further, in S40, the CPU 21 assigns “new” as an attribute to the travel guidance information generated in S39, indicating that the information has not been distributed from the server device 4 in the past. Thereafter, the link to be processed is switched, and the process returns to S36.

  On the other hand, when it is determined in S37 that the travel guidance information has been read (S38: NO), that is, the travel guidance information relating to the link to be processed in the same travel has been transmitted to the vehicle that has requested the travel guide information in the past. If it is distributed, the process proceeds to S41.

  In S41, the CPU 21 determines the driving guidance information read out in S37 (that is, the driving guidance information previously distributed to the vehicle that has requested the driving guidance information) and the link to be processed at the present time. It is determined whether or not the travel guidance information completely matches. For example, if the traveling direction of the vehicle at the guidance intersection has changed or the content of the event (congestion or the like) targeted for guidance has changed from the time when the past travel guidance information was created to the present, the reading in S37 is performed. The issued travel guidance information and the travel guidance information necessary for guidance on the link to be processed at the present time have different contents. In addition, the case where the timing at which the guidance is performed is changed even when the contents of the guidance (phrase and output image) are the same also corresponds to the case where the traveling guidance information is different.

  If it is determined that the traveling guidance information read in S37 and the traveling guidance information necessary for guidance for the link to be processed at the present time completely match (S41: YES), the traveling guidance information is already determined. Since the necessary travel guidance information is distributed to the vehicle that has requested the travel guidance information and is assumed to be stored in the distribution information DB 46, the process ends without generating new travel guidance information. Thereafter, the link to be processed is switched, and the process returns to S36.

  On the other hand, if it is determined that the traveling guidance information read in S37 does not completely match the traveling guidance information required for guidance for the link to be processed at the present time (S41: NO), S42 is reached. Move to.

  In S42, the CPU 21 provides a vehicle guidance such as a voice guidance phrase output in the vehicle, image data output in the vehicle, an intersection name of the guidance intersection, a position coordinate of the guidance intersection, an entrance link ID and an exit link ID at the guidance intersection. Various kinds of information necessary for the information are acquired from the device-side map information 25 or the external server, and in particular, a portion (change portion) different from the travel guidance information read in S37 is distributed as travel guidance information to the navigation device 1. Generate. However, in S42, not only different portions but also overlapping portions may be generated as travel guidance information.

  Further, in S43, the CPU 21 assigns, as an attribute, to the travel guidance information generated in S39, which indicates that the content of the travel guidance information previously distributed from the server device 4 is to be changed. Thereafter, the link to be processed is switched, and the process returns to S36.

  Next, in S44, the CPU 21 determines, for the link train for the predetermined distance created in S35, all the travel guidances created in S39 and S42 in the past processing for the vehicle that has requested the travel guidance information. Read information. Note that the past process is a process executed within the same traveling, that is, after the ACC power (accessory power supply) of the vehicle that has requested the traveling guidance information is turned on. If, among the read travel guide information, there is travel guide information that has not been compared in S38 or S41, that is, travel guide information that is no longer necessary for guidance at the present time, the travel guide The information is also generated as travel guidance information to be distributed to the navigation device 1. Furthermore, “delete” indicating that the travel guide information distributed in the past from the server device 4 is deleted is added to the travel guide information as an attribute.

  Thereafter, in S45, the CPU 21 transmits the travel guidance information generated in each of S39 to S44 to the navigation device 1 of the vehicle that has requested the travel guidance information. Note that any attribute of “new”, “change”, and “delete” is added to the transmitted travel guidance information.

  Next, after receiving the travel guidance information 26 distributed from the server device 4 in S6 and performing a later-described DB update process (S7) based on the received travel guidance information 26, the CPU 51 of the navigation device 1 executes The following describes a moving guidance processing program to be executed.

  In S8, the CPU 51 specifies the current position of the vehicle based on the detection result of the current position detector 31 and the map information. When specifying the current position of the vehicle, a map matching process for matching the current position of the vehicle with the map information is also performed. The specification of the current position of the vehicle is basically performed based on the terminal-side map information 47 of the navigation device 1. However, when the version of the terminal-side map information 47 of the area where the vehicle is currently located is old, or when the navigation device 1 When the map information does not have the map information, the map information may be specified using the map information for specifying the current position of the vehicle acquired from the server device 4.

  Next, in S9, the CPU 51 determines whether or not it is time to acquire audio data for performing travel guidance. Specifically, the timing at which the current position of the vehicle is located 500 m before the timing at which the audio data is output, or the timing at which the current position is 5 seconds before the current vehicle speed is set as the audio data acquisition timing. The voice data for performing the traveling guidance includes, for example, specifying a guidance intersection, guiding the traveling direction of a vehicle at the guidance intersection, and congestion sections, lane regulation, railroad crossings, lane change sections, merging sections, and the like. There is voice data that guides the event. Further, the acquisition timing of the audio data can be appropriately changed as long as it is before the timing of outputting the audio data. The case where the request button arranged on the navigation device 1 is operated is also included in the audio data acquisition timing.

  If it is determined that it is time to acquire voice data for performing travel guidance (S0: YES), the process proceeds to S10. On the other hand, if it is determined that it is not time to acquire the voice data for performing the travel guidance (S9: NO), the process proceeds to S11.

  In S <b> 10, the CPU 51 reads out, from the travel guidance information 26 previously distributed from the server device 4 and stored in the distribution information DB 46, the identification information of the voice phrase that specifically specifies the voice data to be acquired. Then, the CPU 51 acquires audio data corresponding to the read identification information. The CPU 51 reads out the stored sound data when the corresponding sound data is stored in the storage medium of the navigation device 1, and acquires the corresponding sound data from the server device 4 when the corresponding sound data is not stored. .

  Next, in S11, the CPU 51 determines whether or not it is time to output audio data for performing travel guidance. For example, the timing of outputting the voice guidance for the guidance intersection is 300 m, 100 m, and 30 m before the guidance intersection. In addition, when there is an event to be guided to the occupant such as a congested section, a lane regulation, a railroad crossing, a lane change section, and a merging section, a predetermined distance of the event (the distance is appropriately set according to the content of the event). The front is the output timing of the audio data. Further, the case where the request button arranged on the navigation device 1 is operated is also included in the output timing of the audio data.

  Then, when it is determined that it is the output timing of the voice data for performing the traveling guidance (S11: YES), the process proceeds to S12. On the other hand, when it is determined that it is not the output timing of the voice data for performing the traveling guidance (S11: NO), the process proceeds to S13.

  In S12, the CPU 51 outputs the audio data acquired in S10 from the speaker 36. For example, at the timing when the vehicle is located 300 m before the guidance intersection, a sound such as “approximately 300 m ahead, right (left) direction” is output. Thereafter, the process proceeds to S13.

  In S13, the CPU 51 determines whether it is time to acquire image data for performing travel guidance. Specifically, the timing at which the current position of the vehicle is located 500 m before the timing at which the image data is output, or the timing at which the current position is 5 seconds before the current vehicle speed is set as the image data acquisition timing. The image data for performing the travel guidance includes, for example, an enlarged view of an intersection. Further, the acquisition timing of the image data can be appropriately changed as long as it is before the timing of outputting the image data.

  If it is determined that it is time to acquire image data for performing travel guidance (S13: YES), the process proceeds to S14. On the other hand, when it is determined that it is not time to acquire the image data for performing the travel guidance (S13: NO), the process proceeds to S15.

  In S14, the CPU 51 reads out, from the travel guidance information 26 acquired from the server device 4 in S6, identification information for identifying, in particular, image data to be acquired. Then, the CPU 51 acquires image data corresponding to the read identification information. The CPU 51 reads out the stored image data when the corresponding image data is stored in the storage medium of the navigation device 1, and acquires the corresponding image data from the server device 4 when the corresponding image data is not stored. .

  Next, in S15, the CPU 51 determines whether or not it is time to output image data for performing travel guidance. For example, the timing of outputting the enlarged view of the intersection at the guidance intersection is 500 m before the guidance intersection.

  Then, when it is determined that it is the output timing of the image data for performing the traveling guidance (S15: YES), the process proceeds to S16. On the other hand, when it is determined that it is not the output timing of the image data for performing the traveling guidance (S15: NO), the process proceeds to S17.

  In S16, the CPU 51 outputs the image data acquired in S14 to the liquid crystal display 35. For example, an enlarged view of an intersection at a guidance intersection ahead of the traveling direction of the vehicle is displayed. Thereafter, the process proceeds to S17.

  In S17, the CPU 51 determines whether or not the vehicle has reached the destination.

  When it is determined that the vehicle has reached the destination (S17: YES), the movement guidance processing program ends. On the other hand, when it is determined that the vehicle has not reached the destination (S17: NO), the process proceeds to S18.

  In S18, the CPU 51 determines whether or not the vehicle has traveled a certain distance (for example, 1 km) since the travel guidance information 26 was previously obtained from the server device 4 (S6).

  If it is determined that the vehicle has traveled a predetermined distance since the previous time when the travel guidance information 26 was obtained from the server device 4 (S18: YES), the process returns to S5, and the travel guidance information corresponding to the current position of the new vehicle is provided. 26 is received from the server device 4. Thereafter, travel guidance using the received travel guidance information 26 is performed. That is, in the present embodiment, every time the vehicle travels a certain distance, the travel guidance information 26 necessary for guidance output in a section of 10 km along the guidance route 61 from the current position of the vehicle is sequentially received from the server device 4. It will be.

  On the other hand, if it is determined that the vehicle has not traveled the predetermined distance since the travel guidance information 26 was previously acquired from the server device 4 (S18: NO), the process returns to S8, and the travel guidance is continued.

  Next, a sub-process of the DB update process executed in S7 will be described with reference to FIG. FIG. 7 is a flowchart of a sub-processing program of the DB update processing.

  The subsequent processing of S51 to S56 is performed for each information unit (specifically, for each guidance to be output) with respect to the travel guidance information received in S6. Then, the process proceeds to S8 after the processes of S51 to S56 are completed for all the traveling guidance information received in S6.

  First, in S51, the CPU 51 reads an attribute added to the traveling guidance information to be processed. Note that the travel guidance information distributed from the server device 4 is provided with one of the attributes “new”, “change”, and “delete” as described above (S40, S43, S44).

  Next, in S52, the CPU 51 determines whether or not the attribute assigned to the traveling guidance information to be processed is “new”. The “new” attribute is an attribute indicating that the information has not been transmitted from the server device 4 in the past.

  Then, when it is determined that the attribute added to the traveling guidance information to be processed is “new” (S52: YES), the process proceeds to S53. In S53, the traveling guidance information to be processed is newly stored in the distribution information DB 46. The travel guidance information stored in the distribution information DB 46 is used for traveling guidance of the vehicle as described above (S9 to S16).

  However, there is a case where other travel guidance information stored in the distribution information DB 46 is changed as the travel guidance information whose attribute is “new” is newly stored in the distribution information DB 46. Specifically, as shown in FIG. 8, when the guidance intersection is continuous within a predetermined distance W (for example, 300 m) and the traveling guidance information for guiding the guidance intersection on the back side is newly added, In some cases, the contents of the traveling guidance information for guiding the guidance intersection on the near side may be changed. For example, in the example shown in FIG. 8, the voice guidance for the guidance intersection on the near side is changed from "soon, right (left) direction" to "soon, right (left) direction, right ahead (left) direction". Will be changed.

  On the other hand, when it is determined that the attribute assigned to the processing-target traveling guidance information is not “new” (S52: NO), the attribute assigned to the processing-target traveling guidance information is “change”. It is determined whether or not (S54). Note that the “change” attribute is an attribute indicating that the information has been transmitted from the server device 4 in the past, but the content has been partially changed.

  If it is determined that the attribute assigned to the processing-target travel guidance information is "change" (S54: YES), the process proceeds to S55. In S55, the information to be changed is updated (changed) from the travel guidance information stored in the distribution information DB 46 to the newly distributed content using the travel guidance information to be processed. Note that the changed travel guidance information stored in the distribution information DB 46 is used for travel guidance of the vehicle as described above (S9 to S16).

  Then, when it is determined that the attribute given to the traveling guidance information to be processed is not “change” (S54: NO), that is, when the attribute given to the traveling guidance information is “delete”, The process moves to S56. In S56, the information to be deleted is deleted from the travel guidance information stored in the distribution information DB 46. Then, the process proceeds to S8 after the processes of S51 to S56 are completed for all the traveling guidance information received in S6.

  By performing the above-described DB update process every time the travel guidance information is received from the server device 4, the distribution information DB 46 of the navigation device 1 includes a section for 10 km along the guidance route 61 from the current position of the vehicle. The traveling guidance information 26 necessary for the outputted guidance is stored. As shown in FIG. 9, as the current position of the vehicle moves, the travel guidance information 26 necessary for guidance also changes, but the distribution information is distributed in accordance with the attribute given to the travel guidance information distributed from the server device 4. By updating the DB 46, every time the travel guide information 26 is received, the travel guide information 26 corresponding to the surrounding situation at that time and the current position of the vehicle can be stored.

For example, in the example illustrated in FIG. 9, at the first (at the start of traveling) distribution timing of the traveling guidance information 26, the traveling guidance information 26 at the guidance points “001” and “002” within 10 km from the current position of the vehicle. Is distributed as the driving guidance information 26 having the attribute “new” and stored in the distribution information DB 46.
At the next delivery timing of the traveling guidance information 26, the traveling guidance information 26 at the guidance point “003” newly included within 10 km from the current position of the vehicle is added as the traveling guidance information 26 with the attribute “new”. Delivered. Since the travel guidance information 26 at the guidance point "002" is not distributed again, the communication amount can be reduced.
Thereafter, at the third delivery timing of the travel guidance information 26, the travel guidance information 26 at the guidance point “004” newly included within 10 km from the current position of the vehicle is added as the travel guidance information 26 with the attribute “new”. Delivered. On the other hand, when the guidance point “002” does not require guidance for some reason (change in traffic event, change in guidance route, etc.), the travel guidance information 26 with the attribute “delete” is distributed to “002”. The travel guidance information 26 at the guidance point of "" can be deleted from the distribution information DB 46. As a result, erroneous guidance in the vehicle can be prevented.
Further, at the distribution timing of the fourth travel guidance information 26, if the guidance start position of the guidance point “003” is changed for some reason (change in traffic event, change in guidance route, etc.), the attribute “ By distributing the travel guide information 26 of “change,” the travel guide information 26 at the guide point of “003” can be corrected in the delivery information DB 46. As a result, it is possible to provide accurate guidance according to the current vehicle situation and surrounding situation.

  As described in detail above, the navigation device 1, the travel guidance system 2, and the computer program executed by the navigation device 1 according to the present embodiment use the travel guidance information 26 distributed from the server device 4 to travel the vehicle. Is performed, the travel guidance information with the attribute is received from the server device 4 at predetermined intervals based on the current position of the vehicle (S6), and the distribution information DB 46 storing the received travel guidance information 26 is received. On the other hand, the vehicle is updated according to the attribute given to the travel guidance information 26 (S7), while the travel guidance of the vehicle is performed using the travel guidance information 26 stored in the distribution information DB 46 (S9 to S16). While the traveling guidance based on the latest guidance information is made possible, the communication amount between the server device 4 and the navigation device 1 is reduced. It is possible to reduce as far as that can.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various improvements and modifications can be made without departing from the spirit of the present invention.
For example, in the present embodiment, the navigation device 1 has the terminal-side map DB 45 in which map information is stored, but the terminal-side map DB 45 may be omitted.

  Further, in the present embodiment, the route search processing is performed by the server device 4, but may be performed by the navigation device 1.

  Further, in the present embodiment, there are three types of attributes “new”, “change”, and “delete” as attributes to be added to the traveling guidance information, but the number of attributes may be two or less, or three or more. For example, only "new" and "change" may be used.

  In addition, the present invention can be applied to various devices having a route search function and a travel guidance function other than the navigation device. For example, the present invention can be applied to mobile phones, smartphones, tablet terminals, and the like (hereinafter, collectively referred to as communication terminals). Further, the portable communication terminal is not limited to the traveling support for the vehicle, and can also perform the traveling support for the pedestrian or the bicycle.
