由路段交通量估计交通起止点矩阵OD时,一般都要求解非线性的目标函数,使用通常的随机搜索算法容易陷入局部最优的陷阱。本文将模拟退火算法应用于OD估计问题,使用双层规划的OD估计模型,并给出了启发性算法。
It is generally required to solve the nonlinear objective function when estimating the traffic starting and ending matrix OD by the traffic volume of the road section. It is easy to fall into the local optimum trap using the usual random search algorithm. In this paper, the simulated annealing algorithm is applied to the OD estimation problem. The OD estimation model of bilevel programming is used and the heuristic algorithm is given.
