交通影响分析(TLA)范围是TIA中重要指标之一.本文针对其确定方法存在缺陷,分析其中的基本问题,包括分析流程、关键问题、典型路网等,提出操作性强、针对不同区域等级的TIA范围确定方法.该方法考虑了3个主要因素:道路交通环境,项目产生量及其方向性.结合上海市交通状况,针对A-E五种区域等级在相应的交通影响分析阈值和出行量等级的前提下,确定TIA范围的指标.数据表明:上海市的典型路网为三车道的主(次)干道,在区域交通等级A下,交通影响分析阈值为200～500、500～1000和≥1000下的交通影响分析范围分别为3、3、1个交叉口,B、C级下分别为5、4、2和6、5、3.当区域交通状况等级为D和E时,一定需要做交通影响分析,具体出行量等级和交通影响分析范围至少要满足C级情况.

Analysis scope is one of the indexes of traffic impact analysis (TIA). Focusing on the shortcomings of current methods,the paper analyzes some key problems including analysis flow,typical road networks and so on,and proposes an effective method of disseminating analysis scope,which considering three main factors,road traffic surroundings,flows from project,and its direction. Taking Shanhai city as an example,the analysis scope are concluded based on five types area level (A - E) and their thresholds of TIA and level of travel flow. Results indicate that,at level A and thresholds as 200- 5110,500- 1000 and ≥ 1000,their analysis scopes are 3,3,1 intersections,respectively. 5,4,2 are for level B,and 6,5,3 are at least for level C,D,E,respectively. The TIA is necessary when the regional traffic status located in level D and E,and the travel volume and TIA scope should meet level C.
