Abstract

An algorithm to combine VICS data and probe-vehicle data is proposed to construct a dynamic route guidance system with a high accuracy and wide coverage area Factors causing the discrepancy between probe data and VICS data are examined at first by the time tables accumulating one month data Based on the results, the functions to correct VICS data is developed Link time tables for each day and time slice are constructed next by accumulating probe-vehicle data collected through nine months, and missing values are filled by VICS data The results of the experiments comparing the time tables and practice vehicle nuis suggest that developed time table can improve accuracy in travel time estimation compared with VICS data.
