| 摘 要： | 首先分析交通需求预测中基于起点-迄点的OD(origindestination)分布矩阵与产生点-吸引点的PA(producingabsorbing)分布矩阵的概念以及区别;然后针对实际中经常将二者混淆的情况,分析了将OD矩阵转化为PA矩阵的方法,并特别针对运用流量反推OD技术的情况,提出一种新的转化方法;最后通过实际调查数据验证此方法的精度.

| Abstract: | Firstly this paper analyzes concept of O-D(origin-destination)distribution matrix and P-A(producing-absorbing)distribution matrix which are both applied in traffic demand analysis and the difference between them.Secondly this article analyzes the methods of the conversion from O?-D matrix to P-A matrix due to the situation of confusing them in practice frequently,and especially it brings forward a new conversion method for another situation of applying the technique of estimating O?-D demand from link traffic flow volume.Finally it examines the precision of the above method by using practical survey data. |
