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 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.

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.
摘要翻译：调节信息分析系统基于从多个车辆发送的探测信息来确定施加在要分析的目标道路或交叉点上的过境规则。分析终端通过检测在目标道路或交叉口处是否存在表示违反要分析的过渡方法的转移的探测信息（例如右/左转弯禁止）是否存在，是否有效。分析终端基于目标道路或交叉点的几何形状等来确定，如果存在驾驶员希望避免过渡目标路线或交叉路口的避免因素。如果发现避免因素，则用于确定过境规则的存在或不存在的探测信息的数量增加，从而在抑制探测信息的总量的同时提高确定精度。
