Analysis of Day-to-Day Variations of Travel Time Using GPS and GIS
説明
This paper presents an analysis of day-to-day variations of travel time on road network using Global Positioning System (GPS) and Geographic Information System (GIS). Data collection system was developed using GPS connected with notebook PC, which can capture vehicle movement of multiple days. One-week vehicle travel surveys using the system were conducted for commuting drivers in local cities. Methods for handling GPS data on GIS platform were summarized, and day-to-day variations of travel time and speed were analyzed in the study area. Although positional data are very promising, usefulness in travel time studies depends on the process of data handling and the quality of GIS database.
