| 摘 要： | 基于对环境交通容量和交叉口运行状况的分析,提出交叉口的环境交通容量优化模型。主要利用峡谷街道排放模型和北京工业大学修正箱式模型来确定交叉口污染物的排放。模型的优化目标是交叉口通行能力的最大化,利用了非线性规划理论,并根据一般约束条件下的广义惩罚函数法进行求解。运用实例说明在一定的污染物条件下交叉口所能达到的通行能力。该模型对交叉口的设计、管理和改善有一定的参考意义。

| Abstract: | After the analysis of environmental traffic capacity and the operation situation of urban intersection,the optimal model of environmental traffic capacity(ETC) on urban intersection is established,and the allowable pollutant emission at intersection is determined by utilizing the street canyon pollution model and revised Beijing University of Technology(BJUT) box model.The optimal object of the model is the maximum of traffic volume of urban intersection.Utilizing non-linear programming theory,the solution ... |
