For example , you could calculate a specialized or generalized cost function based on a formula you believe to be appropriate 比如,你可用一个你认为合理的公式得到一个函数来计算专门的或者通用的成本。
These methods are usually encountered when there is no information available concerning the network interzonal distances , travel times , or generalized costs 如果不能得到小区之间的距离,出行时间或者运输成本,这种方法就有困难。
Usually , in trip distribution , a new flow matrix is forecasted based on estimates of future productions and attractions and measurements of current flows or measurements of the generalized cost of each trip 通常,在出行分布中,通过调查现状交通量和运输成本以及预测未来年发生、集中量,最后得到一个新的流量矩阵。
Based on the former studies of the network balance , this paper proposes the concept of the multi - mode network balance : many traffic modes run on a traffic network under the designated od matrix , travelers are unable to obtain smaller generalized cost by changing traffic modes or trip routes , this state reaches the multi - mode network balance 在以往对交通领域中平衡问题研究的基础上,提出了多种方式运行下网络平衡的概念,即在多种交通方式运行的网络上,给定od交通量情况下,出行者无法通过改变出行方式或出行路径,获得更小的广义费用,此种状态达到多方式运行下交通网络平衡。
