INTERSECTION DETERMINATION METHOD

摘要

PROBLEM TO BE SOLVED: To inexpensively and speedily determine the presence/absence of a signal at an intersection to be determined. SOLUTION: Probe information including coordinate information, stop information and start information corresponding to an intersection to be determined and the azimuth information of entry to the intersection to be determined is extracted, and the stop time of a probe car which has generated the extracted probe information is calculated, and the presence/absence of a signal in the intersection to be determined is determined based on the distribution of the acquired stop time.
