Greater understanding of the topological evolution characteristics of the supply side of urban transport systems could help urban planners and policy makers uncover patterns of both city growth and road development. This paper examines the road network topological evolution characteristics of a unique government-oriented development district, Shanghai Pudong New District, from 1995 to 2007, where a road-name–based dual approach is adopted to capture the homogeneity and functional continuity of different segments. The urban road network is found to evolve from a broad-scale system to a scale-free system driven by the government interventions. A generalized extreme value distribution is utilized to provide a general form for the road network topological evolution model with a good fit. This scale-free road network has shown to be effective in supporting economic development. This paper offers a new perspective that describes the patterns of topological evolution characteristics for transportation planners regarding network design and urban planning in the long run.

This journal article asks the question: what will US electricity sector CO 2 emissions be in 2030 if today's inexpensive natural gas and renewable energy subsidies persist? The answer is necessary in order to determine the impact of the US EPA's Clean Power Plan (CPP) announced on
