摘要:
A router particularly providing a P2P traffic supporting router which discriminates and effectively controls P2P (Peer to Peer) traffic transmitted in a network. The router comprises a router part to execute a router function, a discrimination part to discriminate P2P traffic from input traffic, an assignment part to assign discrimination information to the P2P traffic discriminated in the traffic discrimination part, a notification part to create notification information to notify the discrimination information to other routers, and a controller to control the discriminated P2P traffic, wherein the router part outputs the notification information according to directions from the notification part and outputs P2P traffic containing the discrimination information according to directions from the controller.

According to one embodiment, the light-emitting apparatus is provided with a substrate, a plurality of light-emitting devices, and a phosphor layer. The plurality of light-emitting devices are mounted on the substrate. The phosphor layer is formed of a translucent resin containing a phosphor and includes a phosphor portion that is formed in a convex shape and covers a predetermined number of the light-emitting device. Bases of the adjacent phosphor portions are formed by being linked with one another.

A DC power source unit 37 is provided which boosts source voltage from a power source portion 36. A lighting circuit 38 is provided which supplies DC voltage to loads, the DC voltage being obtained by stepping down output current of the DC power source circuit 37. A control circuit 39 is provided which controls the lighting circuit 38 in accordance with at least either voltage or current of LEDs 25 and controls the DC power source unit 37 so that a ratio of output voltage to voltage of the LEDs 25 becomes a preset fixed ratio.

A traffic information providing system externally acquires traffic information including information relating to the travel time of a link, calculates a travel time for a non-provision link to which no travel time is provided through estimate/complement operation. The estimate/complement operation is carried out with use of travel times, emergencies, travel times of links in the vicinity of the non-provision link, and so on, obtained in the near past. The system stores and statistically processes the externally-acquired traffic information, and also estimates a travel time in the near future. When there is an abnormality in the acquired traffic information, the system deletes the abnormality, regards the information as a non-provision link, calculates a probability distribution of travel times of links, calculates a probability distribution of travel times of the entire route made up of a plurality of links, and also calculates a probability for a specific travel time range.
摘要:
In a congestion prediction using measurement data which is acquired by an on-road sensor or a probe car, and which includes none of explicit information about bottleneck points, with respect to time-sequence data on congestion ranges accumulated in the past, data on congestion front-end positions are summarized into plural clusters by the clustering. Representative value in each cluster is assumed as position of each bottleneck. A regression analysis, in which day factors are defined as independent variables, is performed with congestion length from each bottleneck point selected as the target. Here, the day factors refer to factors such as day of the week, national holiday/etc. It then becomes possible to precisely predict a future congestion length.
