摘要:
Systems, methods, and programs, store map data including a roadway network, detect a current position of the vehicle, and detect or receive at lest one of a distance to another vehicle, a speed of another vehicle, and traffic congestion information. The systems, methods, and programs determine whether the vehicle is within a predetermined distance of a passing lane, a climbing lane, or a lane for slower traffic based on the detected current vehicle position and the map data. If the vehicle is within the predetermined distance, the systems, methods, and programs provide guidance regarding the passing lane, the climbing lane, or the lane for slower traffic based on at least one of the distance to the other vehicle, the speed of the other vehicle, and/or the received traffic congestion information.

A CPU of a navigation device transmits probe information including link traveling information and average vehicle speed information at every predetermined time to an information distribution center. On the other hand, when receiving the probe information, a CPU of the information distribution center reads the road type corresponding to each link ID and user's average vehicle speed during uncongested road traveling from the probe information, and determines the vehicle speed region corresponding to this link ID from a vehicle speed region determination table. Thereafter, the CPU of the information distribution center creates traffic information from this vehicle speed region and the probe information, stores it in a center side traffic information DB and statistically processes traffic information of a certain period to generate a link cost corresponding to a link ID and a time zone of a relevant vehicle speed region of statistical traffic information.

Provided is a wiring structure and the like which can completely connect a wiring layer to a body to be wired while keeping insulation between two adjacent wiring layers and realize high density packaging due to a narrowed pitch.In a semiconductor-embedded substrate, a conductive pattern is formed on both sides of a core substrate and a semiconductor device is placed in a resin layer stacked over the core substrate. The resin layer has via-holes so that the conductive pattern and a bump of the semiconductor device protrude from the resin layer. Inside the via-holes, the bump and conductive pattern are respectively connected to via-hole electrode portions whose cross-sectional area has been increased toward the bottom of the via-hole. A void is defined between the via-hole electrode portion and upper portion of the inner wall of the via-hole.

A mesh is placed over an image of an element thereby dividing the image (element) into a plurality of solids. Each of the solids is then divided equally into the even number of parts. Inclusion-ratio determination-points, which are points where the straight lines and the mesh intercross, are decided. Moreover, it is determined whether the inclusion-ratio determination-points are inside or outside of the element. An analytical model for the element is created based on whether the inclusion-ratio determination-points are inside or outside of the element.

Navigation information distribution systems, methods, and programs transfer a piece of vehicle position information to an information distribution center every predetermined time period, the piece of vehicle information including a vehicle position and a time when the vehicle passes through the vehicle position. The systems, methods, and programs receive pieces of vehicle position information and traffic information including congestion information, store the received pieces of vehicle position information in order of arrival, and specify a congested road section on the basis of congestion information. The systems, methods, and programs assign a weight of a first travel distance within the congested road section, the weight of the first travel distance calculated on the basis of two of the received pieces of vehicle position information received from the navigation apparatus and congestion information about the congested section. The systems, methods, and programs calculate a first travel time corresponding to the first travel distance, calculate the congested section travel time necessary for passing through the congested section based on the calculated first travel time, and distribute the calculated congested section travel time to a navigation apparatus.
