摘要
针对现有用路段交通量推算 O-D 的理论和方法存在的问题,用线性代数理论讨论了推算 O-D 中解及其误差情况,在此基础上提出了选择观测路段的方法。用此方法选择观测路段既不降低解的精度又能使投入的费用最小。最后给出了方法应用的实例。
Aiming at the problems existing in the present theories and methods of esti- mating O-D trip distribution from link traffic volumes,this paper discusses the precision of solutions obtained from estimation according to the theory of algebra,and the method of routes choice is put forward.Choosing routes in this method,you will get precise so- lutions at the least cost.An example is given in the end of this paper.
