Abstract:
PROBLEM TO BE SOLVED: To provide a traffic situation identification apparatus capable of estimating a traffic situation in a road section to be estimated on the basis of a traffic situation which is in the light of travel modes such as right/left turn and straight-ahead travel of vehicles traveling around the road section to be estimated.SOLUTION: A traffic situation identification apparatus 1 identifies a traffic situation of each road section on the basis of vehicle probe information. The traffic situation identification apparatus 1 also identifies a traffic situation of each road section for every travel direction after passing of the road section. The traffic situation identification apparatus 1 calculates a coefficient defining a relationship between the traffic situation of each road section and the traffic situation of this road section connected to a road section identified for every travel direction after passing the road section. If the traffic situation of a certain road section is not identified in a specific time zone, the traffic situation identification apparatus 1 estimates the traffic situation of the certain road section on the basis of the traffic situation of a road section connected to the certain road section and identified for every travel direction after passing of the road section in the time zone and the coefficient.SELECTED DRAWING: Figure 2
