城市道路交叉口转弯比例反算模型的一般解法

A General Solution Method for Intersection Turning Movement Proportions Inversion Model

从转弯比例一般方程组入手,提出了用于反算交叉口转弯比例的约束非线性规划模型;采用矩阵描述模型,简便地利用Matlab优化工具箱完成对模型的求解,从而建立了对该转弯比例反演模型的一般解法.通过算例分析,证明该算法得到的转弯比例与实测值有较好的吻合.

This paper presents a constraint nonlinear programming model for estimating the intersection tuming movement proportions. The constraint nonlinear programming model of the turning movement proportions is described by matrixes and then resolved by the optimization toolbox of MATLAB, so the general solution method for the intersection tuming movement proportions inversion model is established. Finally, an example is given to prove the proportions of turning movement acquired by the constraint nonlinear programming model can agree with the field data.
