In this paper, the authors summarized the development and problems existed in the implementation of GIS-T in developed countries and P. R. China. Based on the requirement analyses of GIS-T system structures and functions, some key issues that affect the successful applications of GIS concepts and technology for transportation problems are studied. By using the data-driven ideas, the authors presented some considerations about data collection and update, data sharing, data quality control, data modeling and etc. At the end of this paper, a practical example of GIS-T for the comprehensive transportation planning is described.
