Traffic situation estimation method and traffic situation estimation / provision system using probe information

摘要

The invention relates to a method of presuming traffic conditions for implementing a forecast and a presumption of traffic jam situation in an area where probe cars (101, 102) are not traveling currently, in which the probe cars (101, 102) send floating car data that is times and positions of traveled areas to center facilities (104), and the center accumulates the floating car data in a floating car data database (106) by traffic conditions presumption means (105) and also presumes forecast traffic jam information (120) in the forward areas of the probe cars (101, 102) and presumed traffic jam information (121) in the backward areas thereof by using the current floating car data and the floating car data database (106) accumulated from the past to the present.
