existing research results, mainly to network reliability, average network traffic flow parameters such means to evaluate the road network traffic conditions.
现有研究成果中,主要以路网可靠性、路网交通流参数均值等方式来评价路网的交通状态。
on the basis of the above result, the characteristics of urban road network traffic system are studied and the condition which can make the system stable is obtained.
在此基础上,研究了路网交通系统的各种特性,得出了系统稳定的条件。
so this paper combined with road network traffic characteristics, use the road network delay per unit distance which physical meaning was specific as the state of network traffic evaluation method.
本文结合实际路网交通特征,选择路网单位里程延误这一物理意义较为明确的指标,作为路网交通状态的评价方法。
currently, the state evaluation of the road traffic has been more mature; however, the study of the evaluation of the regional road network traffic conditions also not much.
目前道路交通状态评价研究已经较为成熟,但面向区域路网交通状态评价领域的研究还并不是很多。
