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 devices and programs obtain network data including nodes and links, and link information including (i) travel times for traveling a link included in the network data, the nodes and the links representing a road network, and (ii) for each entry link or each exit link, information that identifies a value representing statistical variation of travel times for the link, the entry link being a link entering a node at one end of the link, and the exit link being a link exiting from a node at another end of the link. The devices and programs search for a recommended route by taking into account (i) a travel time to a destination, based on the network data and the link information, and (ii) cost values identified based on a representative value of travel times for a link and a value representing statistical variation of the travel times.

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 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： 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.
