For example , you could calculate a specialized or generalized cost function based on a formula you believe to be appropriate 比如,你可用一個你認為合理的公式得到一個函數(shù)來計算專門的或者通用的成本。
These methods are usually encountered when there is no information available concerning the network interzonal distances , travel times , or generalized costs 如果不能得到小區(qū)之間的距離,出行時間或者運輸成本,這種方法就有困難。
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,通過調(diào)查現(xiàn)狀交通量和運輸成本以及預(yù)測未來年發(fā)生、集中量,最后得到一個新的流量矩陣。
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 在以往對交通領(lǐng)域中平衡問題研究的基礎(chǔ)上,提出了多種方式運行下網(wǎng)絡(luò)平衡的概念,即在多種交通方式運行的網(wǎng)絡(luò)上,給定od交通量情況下,出行者無法通過改變出行方式或出行路徑,獲得更小的廣義費用,此種狀態(tài)達到多方式運行下交通網(wǎng)絡(luò)平衡。
