目前交通节约集约用地更多的是各种交通方式各自开展,而且主要在设计、施工阶段从工程技术角度等实现节约用地。应跳出工程技术层面,从制度建设上促进交通节约集约用地,从宏观、中观和微观三个层面研究交通节约集约用地。一、交通基础设施网络大发展决定了交通节约集约用地的紧迫性截止2012年底,我国铁路营业里程9.8万公里,公路通车里程424万公里(其中高速公路9.6万公里), At present, land for traffic conservation and intensive use is more developed by various means of transportation, and land conservation is mainly realized from the perspective of engineering and technology during the design and construction phases. Should jump out of the engineering and technical level, from the institutional building to promote traffic conservation and intensive land use, from the macro, meso and micro three levels of land intensive research on traffic conservation. First, the great development of transportation infrastructure network determines the urgency of traffic conservation and intensive land use. By the end of 2012, the mileage of our railway business was 98,000 km, the mileage of highway opened to traffic was 4.24 million km (including 96,000 km of expressway)
