Based on time series Landsat MSS/TM/ETM + imagery and historical census data, analysis of the relationship between land use dynamics, built-up land expansion patterns, and underlying driving forces from 1978 to 2008 was performed, using an integrated approach of remote sensing (RS) and geographic information system (GIS) techniques and statistical methods. The results showed that rapid expansion of built-up land in the Hangzhou Metropolitan Area (HMA) led to accelerated land use conversion. The built-up land increased from 319.3 km2 in 1978 to 862.5 km2 in 2008. Expansion patterns of built-up land in the HMA were essentially characterized by axial expansion centered on the former city proper before 1991. In 1996 and 2001, two significant administrative division adjustments for the former city proper and two neighboring municipalities occurred. This led to the success in implementing strategies of "frog-leaping development along the Qiantang River" and "crossing the Qiantang River and developing southward". Spatially, a closer linkage between the former city proper and two neighboring municipalities was established. Consequently, rapid development of infrastructures, facilities, intensive industrial parks, and urban and rural settlements along the Qiantang River resulted in the eastward and southward expansion of built-up land. Thus, from 1991 to 2008 the model of urban expansion resulted in a multi-nuclei pattern. Furthermore, as shown with detailed analysis, the growth pattern of built-up land of the HMA is highly correlated with socio-economic factors, including the gross domestic product (GDP), per capita disposable income, popul

Scientific development is an invaluable asset to a country. Policies and development modes should be carried out based on scientific findings not only in industry, but also in transportation infrastructure construction. Building an integrated transportation system, which is in line with the national requirements of China and supports sustainable socio-economic development, is a key strategic issue related to building a moderately prosperous society and achieving realistic goals of a medium-level developed country. Based on a systematic review of the advances in China's transportation infrastructure over the last 60 years, this paper explores the main drivers of transportation development, including national policy, transportation structure, investment efficiency, and technological innovation. Analysis shows that China's comprehensive transportation infrastructure construction since 1949 can be divided into five stages initiated by these drivers, which correspond to four transition modes: policy transition, structural transition, efficiency transition, and technology transition. The transition path of China's transportation development shows that the dominant factors have changed, and the interval for each transition has shortened. With the implementation of the '12th Five-Year Plan', China's transportation infrastructure construction is showing some new characteristics and facing a new development transition. Finally, this paper analyzes the trends in transportation development in China and concludes that technological innovation will be the main driving force to increase the transportation supply and service area in the future.
