| 摘 要： | 在传统的OD矩阵估计模型的基础上,并在路段分配概率是随机变量这一假设的前提下,给出了一个统一的OD矩阵模型基本形式,针对该OD矩阵估计模型给出了一个基本求解算法———混合遗传算法。该算法是在传统的数学规划方法和遗传算法的基础之上给出的。同时通过算例的求解,分析了算法的优缺点。

| Abstract: | A uniform statistical model for OD estimation is presented,which is based on the traditional modeling in the estimation of OD matrix under the assumption that the link choice proportion is a random variable.And a basic algorithm,hybrid genetic algorithm,is presented for the model,which is based on the combination of traditional method of mathematical programming and the basic genetic algorithm.At last the advantage and disadvantage of the algorithm has been analyzed by solving an example. |
