Road Network,Transportation and Urban Planning

Aiming at the rapid development of large cities,increasing motorization and characteristics of diversified travel modes,this paper discusses the relationship among capacity of roadway system,network layout,and hierarchy of roadways,and stresses that current transportation planning for large metropolitan areas must reserve spaces for future roadway development.While giving the priority to public transit and strengthening highvolume-and-high-speed public transport modes,large metropolitan areas should also emphasize the integration of various travel methods and assign the highest right-of-way to mass travel modes.Finally,the paper stresses that to solve urban transportation problem,the transportation planning must be integrated with urban and regional development planning.
