SYSTEM FOR COLLECTING OF TRAFFIC INFORMATION, REVISION DEVICE OF VALID SAMPLING AND METHOD FOR REVISION OF VALID SAMPLING

摘要

PURPOSE: A traffic information collection system, a valid sample correction apparatus, and a valid sample correction method thereof are provided to flexibly correct a valid sample, thereby simplifying a process for extracting the valid sample. CONSTITUTION: Average velocity is computed by calculating transition speed of a road section(S105). Traffic information of each portable terminal is collected in the road section. An elimination target sample is selected(S109). The elimination target sample is registered in a sample information table(S117).
