GENERATING A ROAD MAP BASED ON LOCATION POSITIONING DATA OF PROBE VEHICLES

In recent years, traffic survey methods using probe vehicles have become popular in Japan. Enormous probe vehicle data are stored in database day after day. These probe data can be utilized not only for observing individual travel behavior in a network but also for measuring LOS (Level of Services) indexes such as travel time, loss time caused by traffic congestion, and so on. In this study the authors intend to propose a new utilization method of the location positioning data collected with probe vehicles.
