Abstract: At present, the common existing problem of Traffic Impact Analysis (TIA) is that there is no control on land development intensity on the stage of approval. This paper evaluates the restriction of residual capacity of intersection on land development intensity. Intersection is frequently a bottleneck of urban road network. With estimation of the proportion of turning flow and consideration of traffic organization, this paper analyzes the production or attraction of the project impact on intersection, and the restricting relations between the residual capacity of intersection and land development intensity in a micro-level. It should form a “Traffic Impact Analysis Opinion” on land development during the process of control regulation adjustment, which can be regarded as a pre-supplementary evaluation for the TIA, to effectively control the “source” of traffic generation. Moreover, an example is used to illustrate the feasibility and operability of the proposed method.

Key words: urban traffic, margin development model, proportion of intersection turning flow, land use, traffic impact analysis

摘要: 审批阶段没有对土地开发强度进行控制是目前交通影响分析(TIA)实施中存在的普遍问题. 对此,提出基于交叉口剩余容量推算土地开发强度的方法并建立了关系模型. 交叉口是城市路网的瓶颈,该方法通过预估交叉口流量转向比例,并结合交通组织确定了交通量在路网上的分担比例,从微观层面分析了项目发生/吸引交通量对交叉口的影响,及其对土地开发余量的制约关系. 提出在控规调整阶段对土地开发强度形成“交通影响分析意见书”,作为TIA前期的补充评价,以有效控制产生交通的“源”. 通过实例分析,证明方法的可行性和易操作性,具有广泛的实用价值.
