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(duì)交通領(lǐng)域中平衡問(wèn)題研究的基礎(chǔ)上,提出了多種方式運(yùn)行下網(wǎng)絡(luò)平衡的概念,即在多種交通方式運(yùn)行的網(wǎng)絡(luò)上,給定od交通量情況下,出行者無(wú)法通過(guò)改變出行方式或出行路徑,獲得更小的廣義費(fèi)用,此種狀態(tài)達(dá)到多方式運(yùn)行下交通網(wǎng)絡(luò)平衡。
