    摘要: This invention is to provide a travel time information arithmetic operation method and apparatus for calculating travel time information using data obtained by a toll collection system. The travel time information arithmetic operation apparatus includes a travel time arithmetic operation section for calculating a travel time (time required by a vehicle to travel from a given point to another given point) of a vehicle on the basis of data obtained by the toll collection system installed on a tollroad and representing the entry point, entry time, exit point, exit time, and model of the vehicle, and date, a tollgate data storage section for storing the data obtained by the toll collection system and travel time data obtained by the travel time arithmetic operation section, and a travel time information arithmetic operation section for calculating an average travel time value using the travel time n-minutes accumulated data stored in the tollgate data storage section and generating travel time information.

    摘要: A navigation server rapidly generating guide support information in view of a traffic state after occurrence of an accidental situation in a road section, and make a navigation device recognize the same. After occurrence of the accidental situation in a target road section, a changing pattern g2(t) of a cumulative traffic volume CQ of a second position x2 during a first period is estimated, on the basis of a value of a traffic volume Q1 of the target road section at the first time t1. Further, a primary guide support information during the first period is generated on the basis of a standard changing pattern g1(t) of the cumulative traffic volume CQ of the first position x1 and a changing pattern g2(t) of the cumulative traffic volume CQ of the second position x2 as the estimation result.
