城市区域交通影响评价定位与方法

Orientation and Methodology for the Regional Traffic Impact Analysis

为了改善现行单体交通影响评价存在的弊端,综合考虑区域土地开发的叠加效应,把区域内部和外围道路瓶颈点作为未来土地开发规模的约束条件,研究了城市区域范围内对土地开发进行交通影响分析的方法.提出了区域交通影响评价方法的定位、技术思路和评价方法,研究了利用目标年道路能力余量推算区域容许土地开发量,建立了逆4阶段用地反馈模型,为城市区域土地开发的控制提供了理论基础.

To improve sufficienl of Traffic Impact Analysis and on the basis of the Pile-up Effect of Local Land Development, Traffic Impact Analysis of land development in urban areas is put forward. The aralysis takes essential traffic bottlenecks in or around the study area as constraint conditions and the paper proposes the positioning, technical solutions and, the assessment method of Regional Traffic Impact Analysis （RTIA）. This paper also studies the key technique of RTIA, which states how to decide regional land development capacity calculated by surplus road capacity in objective year. Inverse Four-stage Land Feedback Model is also set up which will provide the theoretic base for controlling urban regional land use.
