本文通过城市道路交通系统和热力学系统的对比,将热力学的基本理论———熵运用到交通流领域,并在交通流流体理论的基础上建立了熵产生模型。分析确定指定状态时注入的负熵及其意义,建立了主-支路交汇处交通系统的总熵模型,从而得到交通状态判别熵模型和需要注入负熵的条件。研究结果表明,熵值越小,道路服务水平越高。
本文通過城市道路交通繫統和熱力學繫統的對比,將熱力學的基本理論———熵運用到交通流領域,併在交通流流體理論的基礎上建立瞭熵產生模型。分析確定指定狀態時註入的負熵及其意義,建立瞭主-支路交彙處交通繫統的總熵模型,從而得到交通狀態判彆熵模型和需要註入負熵的條件。研究結果錶明,熵值越小,道路服務水平越高。

Through comparing urban road traffic system with thermodynamic system , this study applied the basic theory of thermodynam-ics into the field of traffic flow , and established the entropy production model based on the fluid theory of traffic flow .The negative entro-py which has been injected in the given state and its significance was analyzed , and the total entropy model of traffic system for major -minor intersection was set up , then the discrimination entropy model for traffic states and the condition that need to inject negative entro -py were obtained .The results show that the smaller the entropy value is , the higher the road service level will be .
