【Abstract】 This paper presents a constraint nonlinear programming model for estimating the intersection turning 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 turning 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.更多还原
