Abstract
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.
