摘要

提出了一个四车道模型，探讨了长度为100 m的高速公路工作区占用III和IV车道对车辆油耗的影响。在车辆流仿真中，采用WENO5-RK3方法对模型方程进行了数值求解。提出了一种车辆燃油消耗模型，并与无工作区的情况进行了比较，定义了额外的燃油消耗。仿真结果表明，高速公路工作区域对车辆油耗影响较大，当初始密度经拥堵密度归一化后，一旦超过0.18，就会引发交通拥堵。

Freeway work zone effects on vehicular fuel consumption explored by a four-lane model

A four-lane model is put forward to explore the effects on vehicular fuel consumption of a freeway work zone which has a length of 100 m and occupies lanes III and IV. The model equations are solved numerically in the simulation of vehicular flows by a method called WENO5–RK3. A vehicular fuel consumption model is presented, with an additional fuel consumption defined in comparison with the case in the absence of a work zone. Simulation results show that the freeway work zone affects vehicular fuel consumption significantly, triggers a traffic jam as soon as initial density normalized by jam density is beyond 0.18.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
