It could lead a significant waste of money and time. In recent years, cars equipped with GPS devices become widespread and the location information of those cars could be very useful to estimate traffic condition in the complex city road network. According to the accurate traffic condition estimation, we can provide appropriate route guidance to road drivers and they can avoid the congestion. In this thesis, we use the GPS coordinates of cars driving on the city road network to estimate the traffic condition of road segments. We propose a speed pattern model to describe traffic condition as the travel speed pattern. And we propose a classification-based route guidance model by learning the historic traffic data using machine learning technique. The route guidance model could provide route guidance to drivers according to current traffic condition and how traffic condition would change by the experience learned from historic traffic data.5273189 bytesapplication/pdfen-USGPS速度模式估計路徑指示機器學習speed pattern estimationroute guidancemachine learning[SDGs]SDG9[SDGs]SDG11thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/251291/1/ntu-99-R97725020-1.pdf
