摘要： A central device uses a link shape compression unit to compress information of shape of ups and downs of a road link obtained from a three-dimensional road map, and calculates a geometry parameter based on variation of energy of a vehicle travelling on the road link. An on-board terminal device estimates the vehicle's average travelling pattern by using a travel-pattern-estimation unit based on the geometry parameter calculated by the central device, a link-travelling time estimated from statistically-stored traffic information, and a link length. The on-board terminal device further calculates fuel consumption of the vehicle travelling on each road link based on the estimated travelling pattern and parameters of the vehicle by using a fuel-consumption calculation unit, and then, searches a fuel-efficient route by using the fuel consumption as a link cost. The on-board terminal device has a vehicle-type selector for selecting a type of the vehicle. The present invention can reduce data size of information processed by the on-board terminal device, and facilitate application of a fuel-efficient route search to various types of vehicles.

摘要： There is provided a method and a device for accurately estimating traffic information of a link having no traffic information even if different types of roads are mixed. The device finds a parameter characterizing a damping curve of a quantity of change of relative speed based on stored traffic information for links on a city center side on a minimum-time cost route connecting the city center and suburbs, finds a quantity of change of relative speed of the link having no observed traffic information and estimates its traffic information based on the damping curve. The device also calculates a ratio of quantities of change of relative speed of two links whose road types change as a speed change similarity ratio and estimates traffic information of the link of a second road type from known traffic information of the link of a first road type by using that ratio.

摘要： A statistic DB creation processing section creates a statistic traffic DB, based on past actual traffic data (probe DB or VICS DB), and stores it in a statistic DB storage section. A reference-link-candidate extraction processing section extracts a complement target link (temporal missing link) from the statistic traffic DB, and further extracts complementary-reference-link-candidates for the complement target link, according to plural extraction rules to extract complementary-reference-link-candidates. A complement-evaluation application processing section calculates correlation coefficients of the statistic traffic data of the complementary-reference-link-candidates to the statistic traffic data of the complement target link for the respective extraction rules, assigns a priority order to the extraction rules in the order of higher correlation coefficient, and complements the missing data of the statistic traffic data of the complement target link by the use of the statistic traffic data of the complementary reference link extracted by the extraction rule of the highest priority.
