Abstract: A number of traveling routes are determined by computations, using a route processor and map information on the basis of current position information and destination information. The rating of the current traffic jam or the predicted traffic jam on each of the traveling routes is recognized based on a traffic jam prediction table and a calendar table obtained by statistically processing VICS data and past traffic conditions in terms of temporal elements. The number of traveling routes to which candidate traveling routes are narrowed is increased as the traffic jam rating is raised. Thus, the number of candidate traveling routes from which a user can select the actual traveling route is increased as the traffic jam rating rises in order to accommodate a situation where secondary traffic jams can take place on any candidate traveling route, thereby providing the user with useful traveling route information and appropriate guidance.

Abstract: Disclosed is a subjective optometric apparatus in which the earpiece members and the nose pad member for attaching the main body of the device to the subject can be easily adjusted without involving any effort. The subjective optometric apparatus has a horizontal frame and an inner tube inserted into the horizontal frame, with a support bar for supporting a nose pad member being passed through the horizontal frame and the inner tube. In a state in which the inner tube is being biased by a spring, a rubber member provided in a through-hole of the inner tube abuts the peripheral surface of the support bar to lock the support bar, thereby bringing the nose pad member into a locked state. Further, when a push-button is pushed in against the biasing force of the spring, the inner tube is displaced and the rubber member is detached from the peripheral surface of the support bar, with the result that the nose pad member is released from the locked state and becomes capable of being displaced.
