摘要
Method for approximation of speed (km/h) and traffic flow density (auto/km) relation by new square least method in mathematical traffic flow models is presented. The main idea of modification of least square method is minimization of sum square distances between experimental points and prime line. The non-uniqueness of the problem's solution and reduce the variance of the approximation compared to the classical approach are shown.
