Abstract: An apparatus includes a map data storage device, a map update device, a determination device, and a data production device. The storage device stores map data. The update device reflects a first map update to a first version of the map data to produce a second version of the map data when the first map update occurs. The update device reflects a second map update to the second version of the map data to produce a third version of the map data when the second map update occurs after the first map update. The determination device determines whether the first and second map updates depend on each other. The production device produces map differential data from the first and second map updates when the determination device determines that the first and second map updates depend on each other.

Abstract: A solenoid pump is equipped with a housing formed therein with a fluid passage through which a fluid flows from an inlet port to an outlet port, and a movable member, which is displaced based on an excitation state of a solenoid section, for thereby opening and closing the fluid passage. The fluid passage includes an inlet side passage that communicates with the inlet port, an outlet side passage that communicates with the outlet port, and a pump chamber made up of a space in communication with the inlet side passage and the outlet side passage, and surrounded by the housing and an end portion of the movable member. Accompanying displacement thereof, the movable member opens and closes communication between the pump chamber and the outlet side passage.

Abstract: A movable terminal stores previously a travel time schedule in a regular travel state of a public transportation. The movable terminal executes a route retrieval from candidates containing route sections traveled by using the public transportation and route sections traveled by using different transportation (i.e., foot, vehicle) other than the public transportation. As a result of the route retrieval, when it is determined that the route using the public transportation is more suitable, a request for a multi-modal retrieval based on actual present travel state of the public transportation is transmitted to a center. A center route received thereafter from the center is recorded as a guidance route used for executing route guidance.

Abstract: A traffic situation prediction apparatus for predicting a traffic situation based on a traffic situation statistical data is disclosed. The traffic situation prediction apparatus includes a map information storage and a controller. The apparatus determines, in response to an update of the map information, whether a specific factor affecting a traffic flow has emerged based on a difference between the map information before and after the update. The apparatus identifies an effect on the traffic flow resulting from emergence of the specific when the specific traffic flow effect factor has emerged. The apparatus predicts the traffic situation by incorporating the identified effect into the traffic situation predicted based on the traffic situation statistical data.

Abstract: When a vehicle deviates from a guide route at a first branch point, the state of the first branch point is memorized. Afterward, when a second branch point becomes a target for a route guide and the state of the second branch point is similar to the memorized state, a user of the vehicle is provided with a guide for preventing deviation from the guide route at the second branch point with a manner of the guide changed. This procedure allows learning of tendency of the user with respect to a state apt to cause the user to mistake a guide route. A guide to help prevent a user from deviating from a guide route at a branch point can be thus performed appropriately.
