摘要： Provided is a route through which a user can smoothly travel and on which an evaluation of traveling environment is reflected. A route search system includes a user input receiving unit which uses a delay time from an expected travel time as an index indicating comfort of a route and selects a factor such as traffic conditions and pedestrians set as a condition that a user desires avoidance, a delay time calculation unit which calculates a delay time from an expected arrival prediction time according to map information, traffic information, and traveling environment information so as to reduce a delay as far as possible due to the selected factor, and calculates a cost based on the delay time, and a route search unit which calculates a cost of a link used for a route search from the delay time, and searches a route by using the calculated cost.

摘要： In a traffic information system, the principal component analysis of the floating car data collected in the past is performed for each traffic area. From among the bases representing the traffic data collected on the road-links in the traffic area, the bases which have strong correlation to the road-links on which real-time traffic data were collected are selected. The weighting coefficients for the selected bases are calculated by projecting the real-time traffic data onto the selected bases. The traffic estimation data are calculated by linearly combining the selected bases with the obtained weighting coefficients as the coefficients of the respective bases. The calculated traffic estimation data are used for the interpolation of the road-links on which the real-time traffic data were not collected.

摘要： It is an object of the present invention to provide a route searching which can reflect know-how such as easiness of running included in the probe car data in an entire route from departure place to destination.A center device detects main branch nodes from probe car data received from an in-vehicle terminal device by means of a main branch node detecting section. A probe car data dividing section divides the probe car data into probe segments by the main branch nodes. A route dividing section divides an initial route generated by a initial route generating section based on specified departure place and destination, and a derived route generating section substitutes probe segments for the divided routes so as to generate derived routes. The route selecting section scores the derived routes and select one so as to provide a recommended route in which know-how such as easiness of running included in the probe car data is reflected.

摘要： Because a route selection model for traffic demand prediction of selecting a route from among travel routes in probe data cannot include other routes than the travel route in the probe data, it is not possible to predict a traffic volume on the route that has not been traveled. A traffic-volume prediction device according to the invention includes a simple-network creation device (130) that makes a simple network connecting principal intersections extracted from travelling loci in the collected probe data, a model creation device (140) that determines a utility between the principal intersections based on the data of the travelling loci and calculates a selection probability for each principal intersection based on the utility, and a traffic-volume assignment device (160) that distributes a traffic volume to the routes between the principal intersections according to the selection probability and thereby uses it as the traffic volume for each route candidate to be a traffic demand prediction object.
