摘要： An analyzer of the invention adequately analyzes a change in road network by using probe information generated with driving of a vehicle. This analyzer determines a traffic amount of vehicles passing through a specified section included in the road network from a plurality of the probe information accumulated over a predetermined period. The analyzer also determines a discontinuity rate, which is a rate of incidents that vehicle locations are discontinuous in the specified section, from the plurality of probe information accumulated over the predetermined period. The analyzer detects a change in the road network, based on a degree of change between traffic amounts in two different periods with respect to the specified section included in the road network and a degree of change between discontinuity rates in the two different periods. The detected change in the road network can be used for survey of the road network.

摘要： Route search systems, methods, and programs search for a recommended route for transfer with switching between a plurality of transportation modes. The systems, methods, and programs acquire link information for specifying a link for transfer by each of the plurality of transportation modes and connection information related to connection between links for transfer by different transportation modes, and set a condition for switching from a first transportation mode to a second transportation mode, which is different from the first transportation mode, on the basis of a combination of the first transportation mode and the second transportation mode. The systems, methods, and programs search for the recommended route for transfer with switching between the plurality of transportation modes on the basis of the link information, the connection information, and the set condition, the recommended route connecting links for transfer by different transportation modes.

摘要： A route search apparatus comprises a road information storage part configured to store road information including link information comprised of single link information and composite link information; and a route searcher configured to search a recommended route between two different points using the link information. The single link information includes information regarding an approach link that is a link approaching to a node at one end of a target link, an exit link that is a link exiting from a node at the other end of the target link, and a cost of the target link for entering from the approach link and exiting to the exit link. The composite link information includes information regarding an approach link that is a link approaching to a node at one end of a target link array, an exit link that is a link exiting from a node at the other end of the target link array, and a cost of the target link array for entering from the approach link and exiting to the exit link.

摘要： A regulation information analysis system determines transit regulations imposed on a target road or intersection to be analyzed based on probe information sent from a plurality of vehicles. An analysis terminal determines if transit regulations are in effect or not by detecting if the probe information indicating a transition that violates a method of transition to be analyzed, such as right/left turn prohibition is present at the target road or intersection. The analysis terminal determines, based on the geometric shape and the like of the target road or intersection, if there is an avoidance factor which a driver would desire to avoid transiting the target rode or intersection. The quantity of the probe information used for determining the presence or absence of the transit regulations is increased if the avoidance factor is found, whereby the determination accuracy is increased while the overall quantity of the probe information is suppressed.

摘要： A road network analysis system detects major changes in a road network based on probe information from a plurality of vehicles. The probe information is tabulated and the change in the amount of traffic is calculated for each road with a predetermined time interval. If a remarkable change in the amount of traffic is detected for a road before and after a specific baseline day, it is determined that a major change in the road network affecting the traffic has occurred in the vicinity of the road, and the road is specified as a change-related road. A path search may be performed between the endpoints of a plurality of change-related roads, and the searched paths that have the most overlap with the searched paths are selected so as to identify the change-related roads which are commonly affected by the same cause and the endpoints thereof.

摘要： A travel time data processor extracts a link that is present in the neighborhood of a target link, as a reference link. The travel time data processor selects an identical time zone of the reference link that is identical with the time zone of the target link in which the number of sample data is less than a reference number, and searches for another time zone having similar statistical data to that of the selected time zone. The travel time data processor adds the number of sample data in a time zone of the target link corresponding to the searched another time zone of the reference link to the number of sample data in the time zone of the target link that is equal to or less than the reference number, and generates statistical data from the summed-up sample data.

摘要： Route search systems, methods, and programs search for a recommended route using a cost value of a link or a node that constitutes a route. The systems, methods, and programs calculate the cost value of the link or the node on the basis of calculation material information that serves as a material for calculating the cost value, and specify a reliability degree of the calculated cost value of the link or the node on the basis of a number of pieces of the calculation material information used to calculate the cost value of the link or the node. The systems, methods, and programs correct the cost value of the link or the node, the reliability degree of which has been specified, on the basis of the specified reliability degree, and search for the recommended route using the corrected cost value.
